Best Whole House Water Filter (Here’s Our #1 Pick)

  • by

Are you looking for the best water filter? Many homes are located in areas with a contaminated water supply. Did you know that 900,000 people get sick in the US from contaminated drinking water? It’s not just public water supplies either. The water delivered to your home may have trace amounts of bacteria, lead, chlorine, arsenic, cysts, and other micro-contaminants that make your water unpleasant.

Imagine simply turning on any faucet in your home and enjoying clean, pure water? It even helps with your shower water and washing machines as many whole house water filters also eliminate hard water problems.

What Does A Whole House Water Filter Do?

A whole house water filter cleans your water from the main water line into your home. As soon as water enters your home, it’s already been purified, which means that you can from any faucet any home.

While many people invest in water filter pitchers and other individual filters for faucets, the best whole house water filters provide contaminant-free water to every hose, shower, washing machine, kitchen faucet, ice maker, and so forth, in your home.

There are different whole house water filters that offer more filtration than others, and some whole house water filter types provide ways to soften water or control the pH balance and hardness of the water as well.

Benefits Of Whole House Water Filtration

There are a number of advantages to whole house filtration in comparison to individual filter systems like faucets and filtered water pitchers.

Here are the top benefits of whole house water filtration:
• Improves water taste and smell
• Less wastewater than individual filtered faucets or under-the-sink filters
• Cleans water at the point of entry
• Purifies all water in your home
• Typically removes 97 to 99% of all contaminants
• Longer filter lifetime
• Stronger filtration
• Better for whole house consumption

For those who want the best whole house water filter with multiple stages, water softener, and well water adapter, the Aquasana Rhino Whole House Water Filter offers the best features and purity.

After testing multiple systems, this is the best whole house water filter on the market currently. It’s particularly excellent at treating and purifying water with high levels of chlorine. With a 10-year warranty and large filters, this system is also easy to install and manage for years. It is also significantly cheaper than most systems with a reverse osmosis filtration system.

Top Reasons To Buy

Best Performance for Effective Filtration

Not only does the Aquasana Rhino whole house water filter meet NSF standards, but it also goes beyond, removing almost all traces of contaminants. It’s very effective at removing chlorine.

This is because of the multi-stage filtration that includes four different filter levels. Aquasana has been shown to remove nearly 99% of all contaminants, including chlorine, lead, arsenic, bacteria, viruses, cysts, rust, hard minerals like magnesium and calcium, sediment, and other micro particles. If you are looking for the best water filter, then it must include filters that can reduce contaminants with a 5 micron filter or lower.

Excellent Multi-Stage Filtration

Aquasana built the Rhino whole house filter to remove all contaminants and hard minerals. This means that the system cleans and softens for truly pure water. It’s the best whole house water filter because of its unique upflow tank as well.

The five stages of water filtration include:
Stage 1: 5 Micron Pre-Filter

This step is essential for removing sediment and other microscopic particles such as dust. This is also done first to protect the main carbon tank from clogging and other damage.

Stage 2: UV Water Purifier

If you deal with well water, UV filtration is absolutely necessary for removing bacteria and chlorine. During this stage, water is sterilized.

Stage 3: Carbon Tank

At this stage, a mixture of copper-zinc oxidation and crushed minerals form a barrier against chlorine. It also makes the pH slightly more alkaline through the process of water ionization, which is better for drinking and cooking. Alkaline water is an antioxidant that is often given to patients who suffer from cancer and other terminal diseases.

Stage 4: Carbon Filter

Another layer of filtration removes smaller particles and chemicals, further cleansing water through a carbon media filter. This works well to remove chlorine and bacteria.

Stage 5: 0.35 Micron Filter

In the last stage of filtration, Aquasana built a 0.35 micron filter that removes organic particles and microscopic cysts.

Easy Installation and Maintenance

Another reason why we loved the Aquasana Rhino filter is that it lasts forever. This is a 1,000,000-gallon system that is rated for 10 years for a family of four. The company also makes it easy to install with simple instructions and all the fixtured necessary to set up your filter at the main water line to your home.

The filters are extremely durable, meaning that you won’t have to replace any of the filters for the first year. It also requires no back-flushing since the system cleans itself. That’s incredibly convenient since many other filtration systems require you to change out the filters every 30 to 90 days.

Cheat Sheet: Finding the Best Under Sink Water Filter for Your Household

Are you looking for a system that can do it all? For those who want the best whole house water filter, there are a few out there that have all the bells and whistles so that you never have to worry about contaminants. If you have noticed that the water in your home tastes funny out of the tap or has a funky odor, then you may want to look into a whole house filter system. Filtration improves the taste and smell of water, but it also makes it healthier to drink, cook, and bathe with your home’s water.

Unless you have worked with water filtration and installation in the past, it can be difficult to find the best water filter systems. There are hundreds to choose from, but there are only about 10 water filtration systems that actually work. The best whole house water filter is typically one that includes the features below.

To find the best whole house water filter, we’ve put together a list of features and phrases to help with your search:

NSF Certification: Removes Most Contaminants

The number one thing that a whole house filter should have is an NSF certification. This means that the filter meets high standards for contaminant removal. When looking at the specifications, you should also see a list of contaminants removed including:

• Lead and heavy metals
• Bacteria, viruses, and other diseases
• Chlorine, arsenic, and other chemicals
• Cysts

Overall, most filters need a multi-step filtration process to handle most of the contaminants in the water supply. It’s best to test your water first to see how strong of a filter you need. In addition, well water owners need to look at a UV light for well water and an iron filter for well water for another level of purification.

Multi-Step Filtration with Reverse Osmosis

Most whole house water filters have multiple stages or layers. The first filter is typically a sediment filter that removes all dirt and other micro particles. Chlorine and other chemical removal typically happens in the second stage, which is an activated charcoal or carbon filter is used. This is a must-have for the best whole house water filter systems.

Finally, filters should have a reverse osmosis stage also known as RO filtration, which is a membrane that filters out almost 99% of all other contaminants. It’s used by the best water filtration companies to create extremely purified water.

Flow Rate in GPM

Most houses require a 30 GPM or more flow rate. We’ll explain what this means.

Everyone has to calculate their flow rate according to their home’s needs. Your flow rate may be different from someone else depending on your showerhead, toilet, faucet types, washing machine, and dishwasher.

Flow rate is measured in gallons per minute (GPM), and it matters because your flow rate decides the amount of water that is available to run all the water-dependent appliances in your home.

To calculate your flow rate, you need to look at the demand ratings labeled on all of your appliances, as well as the toilet and faucet. For example, showerheads typically have a 3 GPM flow rate, whereas a toilet may have a 5 GPM flow rate and a dishwasher has a 3 GPM. You are already at 11 GPM.

Houses typically have between 15 to 50 GPM needs, so if you spot a whole house filtration system with a low flow rate below 20 GPM, it’s probably not going to work for all your appliances.

Gallons Per Day = GPD Rating

You also want to know that your system can handle a ton of volume, especially if you have a larger home with many people who take showers, cook, and drink water. The GPD rating of the best whole house water filters is typically over 30 GPD and estimated around 50 GPD with reverse osmosis filters.

Water Filter Life: How Long Do Filters Last

Filter longevity and water filter life pertains to how many gallons the filter can purify before it starts to lose its strength. After that, your filter won’t work properly. You want a system that can last years without ever needing a filter change, but these are typically more expensive. Finding the right filter is a good balance between whether it works with your system and how much water you use.

You also want a system that can last without too much maintenance. This is why you should look at reviews for any filtration system, as you may purchase one thinking it’s a deal, but you have to buy carbon filters every 3 months. This could cost you an extra $200 to $500 per year depending on the filter types and filter load. The manufacturer should include what the filter load is and how often you need to change the filter.

There are also different sizes of filters. With larger filters, you typically don’t have to replace them as much. In addition, more water can flow through larger filters, so it’s important to pick a filter size that is 4.5” by 20,” but this is also particular to your home’s needs. Larger homes will benefit more from higher GPM systems and larger filters.

Water Softener and Filtration

Filtration removes contaminants, but the process also leads to other benefits such as water softening. However, filters and softeners are separate systems. Water softeners use chemicals or materials to remove minerals that cause hard water. However, filters remove chemicals and particles with a filter. Some systems can do both at the same time.


Basically, some water filtration systems are easy and come with instructions that make it simple to set up with any water supply lines. However, others have too many parts or have issues with missing components. It’s best to look at reviews to see how customers felt about installation. However, if you are not comfortable at all with plumbing, you may have to hire a professional to help you install the system.

Warranty and Protection

Anything that works well has a long-term warranty of five years of more. Some systems cover different parts of the system for different lengths of time. You should always read the fine print and look for a moneyback guarantee when buying a filtration system online.

Micron Rating

The best whole house water filters block everything over 0.35 microns. However, these are more expensive than filters that block at 1 micron only. If you consider that a single micron is a one-thousandth a millimeter, then you realize how small this is. However, it has to be to catch microbials and small, invisible particles. However, it’s overkill to have a 0.35 micron level if you don’t have a severely contaminated water supply, which is why you have to check your water first with a water testing kit.

Water Sources for Whole House Filters

Most whole house water filters are set up at the main water line to your home. However, you may have a well or a different setup. It’s important to check the system to know whether you need a well hookup or a municipal supply line hookup.

How Does A Whole House Water Filter Work?

There are actually several different types of systems when it comes to water filtration. Whole house water filters are only the beginning. The process may be different if water softeners, UV filtration, or well water hookups are included.

Whole House Water Filter

This is your typical whole house water filter system. These connect to the main water line of your home, usually right before it even goes to your water heater. Some whole house systems are also able to hook up to your outdoor water needs for sprinklers and irrigation.

What’s included with a typical whole house water filter?

There are a few components to look for in a good water softener, including:
• Carbon tank
• Multiple filters including sediment, carbon, and RO filters
• UV sterilizer (optional)
• Water softener
• Hookups for main water line or well water
• Separate under-the-sink tanks (optional)

The typical water treatment process works like this:

  1. Connect the filter to the main water line.

The filtration must start as soon as the water enters the house. This means that you will hook up most water filtration systems outside at the point of entry, whether you have a municipal water supply or a well.

  1. Water moves through pre-filter to remove sediment and other large particles.

This is the first layer against larger contaminants. At this stage, you may also have a UV filter that uses light to destroy bacteria and chlorine as well.

  1. The next layer of filtration includes crushed minerals like zinc and copper to filter out heavy metals, chemicals, bacteria, and other chemicals.
  2. Carbon filter absorbs remaining contaminants.
  3. Water softening may take place at this level if you have a good combination water filtration and softener system.

This step is beneficial if you have hard water in your home. If you notice that your skin feels dry or your dishes have hard water spots or stains, then you likely need a system that also removes heavy minerals like calcium and magnesium.

  1. Clean, purified water flows through your water heater, faucets, and other appliances.

The process is different depending on the types of filters in the system and how your come connects to a water supply. There are two systems that have significantly different processes than a traditional whole house water filter.

Whole House UV Water Filter

We wanted to look specifically at how water filters work with a UV sterilization process. These are popular with homeowners because they disinfect and protect against viruses and bacteria like E. coli. They are also useful for removing chlorine and lead from the water as well. This is especially useful for well water, as municipality water is typically safe. However, bacteria and other elements may be found in wells.

UV lights work with these filtration systems through a sleeve used inside the water chamber. The water flows in slowly through the filter at first to ensure that it’s treated properly. The UV filter doesn’t ever touch the water, but they still strike and kill the microorganisms to sterilize the water.

Whole House Water Filter For Well Water

Many homes in the US get their water from a private well on the property. One of the main concerns is whether the water is safe or not, especially when the well is older or when soil has been contaminated aboveground. There are naturally-occurring chemicals and minerals in wells, such as coper, calcium, arsenic, and radon. However, runoff into wells may cause pesticides, herbicides, and other chemicals to get into your water supply.

Well water also isn’t treated like municipality water, which means that it doesn’t contain fluoride or sewer pollutants such as pharmaceuticals. It can harbor bacteria, parasites, viruses, and heavy metals though. This is why it’s necessary to have more filtration for well water.

Water filter systems for wells are different than those created for a supply line from a municipality. They are mostly different because of UV filtration, which requires the location to be near a power source.

Whole House Water Filter Reviews

We reviewed some of the best whole house water filters, whittling down our top choices based on the system’s ability to filter out chemicals, minerals, bacteria, viruses, cysts, and other harmful contaminants. We also just their installation process, flow rate, filter quality, warranty, and customer satisfaction.

Aquasana Water Filter: Rhino Whole House Water Filtration System

Aquasana is one of the most well-known whole house filtration systems, and their most popular product is the Rhino whole house filter. This system comes with add-ons, allowing you to create four different types of filtration.

The base model Rhino breaks down into the EQ-1000 and EQ-600, which comes with 3 stages of filtration. This includes a sediment pre-filter, copper-zinc and mineral stone filter, and activated carbon filter. We also checked out the add-ons, including the SteriLight UV filter.

We loved that the system comes with a long filter lifespan, which means low maintenance. It can handle residential and commercial usage with different flow rates. We found that the system was able to remove all contaminants to a 99% pure water result.

The UV filter attaches to the water chamber and effectively kills all the microorganisms. We found that this is the best way to get the purest water, which is necessary for well water systems.

What We Liked

Aquasana makes it easy to install their Rhino filtration system. You simply need to make changes to the piping and connect to the water filter system. The company provides a video on the installation as well as detailed instructions. We were able to install it easily within an hour.

The Aquasana is truly a complete filtration system even with the base Rhino model. It comes with several ways to customize your water filtration, including a UV filter and water softener. This can lead to a longer lifespan for your pipes and appliances.

The system also includes a 0.35 micron filter, which blocks out most of the micro-contaminants that can make it into your water supply.

What We Don’t Like

Do you have enough space for all of the add-ons? The tanks can be quite large, and you’ll need a power supply near the point of entry to install the SteriLight UV filter.

The systems can be difficult to distinguish, so pay attention to specifications and make sure that you know your home’s flow rate. You may need add-ons, which cost a bit more than the base system.

iSpring Whole House Water Filter: WGB32BM 3-Stage Whole House Water Filtration System

The iSpring WGB32BM whole house water filtration system includes a 20-inch big blue sediment filter, as well as carbon block filters. The latest system is equipped with three-stage filtration, which removes pesticides, herbicides, industrial solvents, bacteria, cysts, chlorine, and other contaminants.

As a whole house system, you can install this at the main entry point of your water supply to treat the water in your entire home. While it’s not a RO system, this means that you’ll keep most of the healthy minerals in the water. However, it may not be able to remove hard water minerals like calcium and magnesium from your water if you are looking for a water softener.

This system includes a 100,000 gallon capacity filter made up of coconut shell, activated carbon. This means you only have to replace filters once a year, which is less than most under-the-sink filters and cheaper whole house filters.

We found that the iSpring WGB32BM removes about 95% of all contaminants, including chloramines, chlorine, chemicals, and sediment.

What We Liked

We found that this system is one of the most affordable for homes with a municipal water supply. The three-stage system is perfect for four-person householders or small offices. The three-stage filter includes multiple filters, including a coconut shell carbon block filter that can remove 99% of the chlorine in your water.

We found that the filters were exceptional at purification for most contaminants. It has a 15 GPM flow rate, which is acceptable for most small families. However, you may want to consider a larger system if you have a bigger home with three or more bathrooms and more than four people.

What We Don’t Like

While the iSpring system is affordable, there are a few issues that we should address. For one, it’s not as easy to install as an Aquasana. It requires some plumbing experience and knowledge of mounting brackets and pipes. You also need to check that your pipes match the 1-inch diameter system that iSpring is designed for.

iSpring Whole House Water Filter: iSpring WGB21B 2-Stage Heavy Duty Whole House Water Filtration System

For smaller householders, iSpring also creates a 50,000-gallon capacity water filter system that is best for residential homes. This two-stage filter has a 15 GPM and comes with a one-year limited warranty. This design includes a coconut shell carbon filter. We found that it eliminates 95% of the contaminants, including chlorine, sediments, bacteria, cysts, viruses, lead, arsenic, and others.

Unlike the other system from iSpring, this one comes pre-assembled, so you simply have to attach it to the point of entry to get started. We found that all odors, foul tastes, and clarity were all improved after a thorough test.

The iSpring brand also provides all kinds of installation help and customer service, so you don’t have to worry if there are any issues, such as leaks.

What We Liked

The filtration is quite good for a smaller, two-stage process. In fact, it works almost as well as their larger three-stage system. Since it’s pre-assembled, installation took less time than most of the filtration systems we reviewed. It’s also designed to be compact despite having multiple filters.

The system also tries to mitigate water pressure loss and prevents clogs. This design is particularly important as some filters can alter how your water flows to different faucets, such as your shower. Not only does this system provide reliable multi-layer filtration, but you won’t notice any difference in your water flow. However, you have to make sure that the flow rate matches your household’s needs, as this is a smaller 50,000 capacity system.

What We Don’t Like

Most families will need a larger filtration systems, especially if you have multiple appliances that use water. For example, if you have more than 3 people in your home with a dishwasher, washing machine, shower, and two faucets, you may require a higher flow rate.

Customer satisfaction is generally high, but there were a few complaints about systems that came with leaky tanks. This could be an ongoing issue with the iSpring brand so make sure that you check the tanks and pipes after installation.

Aquasana Water Filter: Rhino Whole House Water Filtration System (Well Water plus SimplySoft + UV)

The Aquasana Rhino system comes with different add-ons. Their whole house water filtration system with well water plus SimplySoft and UV filtration comes with a 1,000,000-gallon capacity and a 10-year limited warranty.

In our research, this was the top combination from Aquasana that includes a three-stage filtration system. It removed 97% of the contaminants, including sediment, chlorine, lead, arsenic, bacteria, cysts, and more. However, that’s not all that the system does. With SimplySoft, the filtration system also prevents hard water from entering your home.

Since it’s such a high-capacity water filtration system, it includes a 20-inch pre-filter, UV SteriLight, and a salt-free water softener. The results include extremely pure water that removed 99.99% of all bacteria and viruses.

We also tested the pro-grade installation kit add-on, which made the system easier to install with adapters for smaller pipes. It also includes shut-off valves, brass fittings, and bend supports.

What We Liked

This is a premium whole house water filter system that provides excellent drinking water and whole house water softening. Most of the contaminants were removed completely after the three-stage filtration. The filters are extremely efficient, and they are rated for 10-year usage or 10 million gallons of water. This means that you don’t have to replace the filters as often as other filtration systems.

Aquasana also has amazing support, and customers love the quality of the filtration. Water tastes absolutely pure, and with SimplySoft, hard water is completely removed from your supply. If you have problems with hard water, then this is the best system for you. The warranty is also impressive, as none other systems have a 10-year comprehensive protection.

What We Don’t Like

While we tested the pro-grade installation kit, you may still need a plumber to ensure that there are no leaks. The easy installation kit was also extra, when it should be included with the system.

The system is also quite large due to the multiple stages and large tank. In addition, we found that the flow rate is lower for such a large tank.

Aquasana Water Filter: Well Water Filter System w/ UV Purifier & Salt-Free Descaler (5 Year System)

Are you looking for a higher capacity system? The five-year system from Aquasana is the best for those with well water systems. It includes a UV purifier and salt-free descaler to keep your pipes and water lines clear. The UV filtration is especially important if you suspect issues with bacteria and viruses.

In addition, this system removes lead, mercury, herbicides, pesticides, VOCs, and much more. This is a high-performance system that includes carbon and KDF filtration. The salt-free descaler is also important if you have issues with sodium and cholesterol.

The Aquasana five-year system also does not require any draining and back-flushing, and it does not de-mineralize your water. This means that your water will still have healthy minerals.

What We Liked

This is one of the easier systems to install from Aquasana. It only takes under an hour to get whole house filtration with a salt-free softener. It includes a carbon media filter, 20-inch pre-filter, and a specialized UV filter.

While this system works with municipal water supplies, it’s best for well water. It’s designed with a unique upflow tank design. This increases the time that the water is treated and also prevents clogging within your pipes.

However, it’s the salt-free technology that is truly special about this particular system from Aquasana. There aren’t too many water filtration systems that include salt-free treatments. The UV filter also delivered with 99% pure water, removing bacteria, viruses, cysts, chemicals, pesticides, and more.

What We Don’t Like

The base install kit includes plastic fittings, post-filter, UV filter, and a 20-inch pre-filter. However, it doesn’t include shut-off valves, bend supports, or brass fittings. For that, you would have to pay extra for the pro grade install kit.

Bluonics Water Filter: 110W UV Light + Sediment & Carbon Well Water Filter Purifier Disinfection System

The Bluonics Water Filter includes a 110W UV light with a sediment and carbon well water filter. With three stages of filtration and a 24 GPM rate, this system produced some of the highest purity rates.

The three-stage filtration process includes a 5-micron sediment filter, 5-micron carbon block filter, and a UV sterilization filter. We found that the system was able to eliminate 99% of all contaminants, including E. coli, bacteria, algae, fungi, viruses, cysts, chlorine, lead, arsenic, and others.

It also can withstand a maximum pressure of 125 PSI. This means that both small and large homes can benefit from this high-capacity system. However, you should expect to replace the UV lamp after one year of use.

What We Liked

Bluonics designed the perfect system with complete instructions that are easy to follow. We were able to set up the system within 20 minutes using the provided equipment and tools. There was also no loss in water pressure thanks to the system’s 125 PSI rating.

The best part about this system is the UV sterilization and three-stage filtration. Our post-filtration tests concluded that all of the contaminants had been removed. The water was odorless and alkaline with absolutely zero chlorine.

The GPM is much higher on this system than with others we reviewed. We were able to operate multiple appliances at the same time, as well as the shower, and we didn’t experience a single drop in pressure or water flow.

What We Don’t Like

The system does require you to replace the filters after 3 months of use. In addition, you’ll need to replace the UV lamp after one year. We felt that Bluonics had an amazing system design, but when it comes to customer service and the warranty, it wasn’t as comprehensive as other brands such as Aquasana.

Top Whole House Water Filter For Well Water

In addition to our main reviews for traditional and combo filtration systems, we also wanted to check out whole house filters fitted specifically for well water homes. We based our rating on how well these systems filtered out common contaminants from wells such as pesticides, herbicides, bacteria, viruses, cysts, rust, and lead.

Aquasana Whole House Water Filter System w/ UV Purifier & Salt-Free Descaler

Aquasana has developed multiple systems for well water homes. The Aquasana Whole House Water Filter System includes a UV purifier and salt-free descaler. It kills bacteria and viruses, but it also removes pesticides, radon, herbicides, rust, lead, and many other contaminants specifically found in wells.

With a 500,000-gallon rating, this system is best for small family homes. This is also a salt-free system that does not demineralize your waters. Instead, it softens the water with a natural conditioner. In addition to being healthier for most people, this system also prevents scale and corrosion on your pipes.

There are additional benefits to this system, as it does not require any electricity, backflushing, or drainage. It has a unique upflow design that increases the duration of time that the water spends in filtration, which results in ultra-pure and softened water for your whole house.

What We Liked

There are some definitive bonuses to this well water system from Aquasana. For one, it removes 99% of all contaminants, including dangerous bacteria and viruses that are often found in well systems.

With a six-stage system and a high-capacity tank, the system has every type of filtration, including a water softener. The filters include a sediment pre-filter, activated carbon filter, post-filter, copper-zinc and mineral stone filtration, UV filter, and salt-free water conditioner. Chlorine levels were reduced to an insignificant amount with this process.

What We Don’t Like

There are some considerations for homeowners with this system. For one, you need to calculate your flow rate and ensure that it matches the maximum 7 GPM flow rate included with this system.

In addition, we found the installation to be a bit difficult. You may need a professional plumber to properly fix this system to your pipes, unless you opt for the pro-grade installation kit.

iSpring Whole House Water Filter: WGB32BM 3-Stage Whole House Water Filtration System

Some filtration systems are designed to optimize water softening, while others remove chlorine and lead at a micro-level. The iSpring WGB32BM is a three-stage whole house water filter designed for well systems. It can reduce magnesium, calcium, lead, arsenic, chlorine, bacteria, cysts, and so many other contaminants.

We found that this system removed 95% of all contaminants, including pesticides and herbicides that often make their way into well water from nearby contaminated soil. The system features a “Big Blue” 20-inch by 4.5-inch filter that allows for a higher PSI level. This means you won’t lose any water pressure.

The other filter is a CTO carbon block filter that uses coconut shells. This extends the total lifespan of the filter, while also providing a higher-degree of filtration overall. This is one reason why the system is NSF-certified.

What We Liked

While this is a smaller-capacity system at 100,000 gallons, the design is rated for 0.25 gallons per second. This means that your water is filtered fast and efficiently. The basics are all here, and it removes most chlorine and bacteria, which is extremely important.

We also liked that you could customize the PSI according to your home’s need. If you have a system with a PSI higher than 90, you may need to add a regulator, but this isn’t typical of homes that would be compatible with this system.

What We Don’t Like

While the system is more affordable than others, it lacks one important feature that most well water designs include. A UV filter is typically necessary to ensure that almost all bacteria, viruses, lead, rust, chlorine, and pesticides are removed from the water before entering the home. Without this feature, it’s slightly inferior to other systems.

Home Master Water Filter: Home Master HMF3SDGFEC

If you are looking for a well water system with high performance and filter longevity, the Home Master Water Filter system is a great start. It provides clear, clean, pressurized water with three stages of water filtration. It also has a higher flow rate of 15 GPM, which is perfect for most families of four.

The filtration system is a little different than others, as it includes radial flow, multiple gradients, and radial carbon filters. This means that it can reduce manganese, hydrogen sulfide, and iron in addition to other contaminants, such as rust, pesticides, herbicides, and chlorine.

In our test, this system reduced contaminants like chlorine by 95 percent, but it excelled at filtration for bacteria and microorganisms, reducing to merely 99 percent.

What We Liked

The Home Master has a higher flow rate than most filtration systems, and the three-stage design includes strong filters that reduce most of the contaminants.

The design also doesn’t reduce water pressure at all, so you can maintain water flow and pressure throughout your home. It also includes filters down to 1 micron, which means that almost all microorganisms, particles, dust, and other microbes won’t get past this system.

What We Don’t Like

While the system is efficient and works well for most homes, you should test your well water beforehand. If you have problems with bacteria and chlorine, it’s best to have a UV filtration system, which Home Master does not include.
