9 Superior Whole House Water Filter Reviews – Get Cleaner Water in 2024

When looking for an all-in-one water filtration system that’s dependable and affordable, our research showed that you can’t go wrong with the iSpring RCC7. This multi-layered system filters over 1,000 different types of contaminants, ensuring clean and healthy water in the home. Although this is not a whole house system, it delivers amazing results at a great price!

What makes the RCC7 one of the best systems out there is its five-stage filtration which eliminates bacteria, viruses, iron, lead, mercury, chlorine, asbestos, and much more. The system consists of three pre-filters: the polypropylene (PP) sediment filter, the granular activated charcoal (GAC) filter, and the carbon block (CTO) filter.

The PP sediment filter removes sediments, dust, sand, dirt, and rust from the water, while the GAC filter ensures that no chlorine comes through. It also makes the water odorless and colorless, while removing foul tastes and cloudiness. The third pre-filter, the CTO filter, removes chloramines and other harmful chemicals.

Here’s what we really loved:

The heart of this excellent filtration system is the RO (reverse osmosis) membrane. It’s a very fine membrane that removes contaminants down to 0.0001 microns. This basically means that nothing except water molecules is able to pass through. After the RO membrane, another GAC post-carbon filter removes possible residual tastes and odors, ensuring perfectly clear and healthy water.

All the filters have to be changed about once or twice a year, depending on water quality and hardness. The only exception is the RO filter, which should be changed after two years. The replacement filters are inexpensive and easy to come by.

With its 75 gallons per day capacity, the RCC7 is perfect for home use. What also sets it apart from most other filtration systems is that it looks great. It also comes with a convenient and visually enticing lead-free brushed nickel faucet.

This system is small enough to easily fit under any sink, and even a beginner can install it in about two hours. All the installation pieces and equipment come with the system, and there is also an instruction manual, as well as many handy YouTube installation videos available. iSpring also offers live phone support, and while doing our research, we’ve confirmed that this company’s customer service is unparalleled.

Our research also showed that there are a few downsides to this iSpring RCC7 RO system. Firstly, the faucet included in the package sometimes starts dripping. Some users report that it started dripping right away, while most report that the dripping begins after six or more months of use.

We also found that the installation manual that comes with the product is a bit outdated, and does not include all the items that come with the product. Luckily, the YouTube videos by iSpring are very convenient and helpful, so the mistakes in the installation manual can be overlooked.

There are some very popular add-ons that go with this product. iSpring ICEK Ultra-Safe Fridge Water Line Connection and Ice Maker Installation Kit is used to connect the water filtration system to the ice maker or water dispenser of a refrigerator. This kit contains all the items you need to install it, including tubing, valves, and a compression fitting set. It’s easy to install, even for beginners, and there are absolutely no tools required.

There’s also iSpring 1-Year Filter Replacement Supply Set for 5-Stage Reverse Osmosis Systems. The set includes two of each of the pre-filters and one post-filter. Each filter is wrapped individually. This replacement set is meant to cover your replacement filter needs for a full year. Note: this set doesn’t include a replacement RO membrane, only pre- and post-filters.

The second filter is the GAC filter which removes chlorine, organic chemicals, suspended particles, dirt, and odors found in tap water. It also removes any unnatural tastes, which provides absolutely clean drinking and cooking water. The CTO or Carbon Block filter is made from fine coconut shell carbon which once again removes suspended particles, chemicals, and dirt on a finer level.

Want to know the best part?

All of the filters have been tested by independent laboratories, so you can be sure they work as promised. All of them also have relevant industry certificates to ensure safety and efficiency.

This water filtration system also includes a pressure gauge and pressure release button. Previous buyers have reported that this means you can easily determine incoming water pressure, as well as replace the cartridge without much hassle. We found that the only downside to this filtration system is that it includes plastic housing caps which can sometimes break if handled roughly.

This whole house filtration system is simple and inexpensive and is a great solution for an average homeowner. Made by a reputable company, our research showed that it mostly provides what it promises.

Our research found that this quality filtration system can provide any household with water that’s free from the taste, smell, and harmful chemicals. It makes it safe for the family, as well as pets and plants. Another advantage of this system that it removes chlorine, radon, VOCs (volatile organic compounds) and other common chemicals. This filter also removes cloudiness, offensive odors, colors, and unpleasant tastes. Basically, the filtered water protects your appliances from accruing any damage, which can increase their efficiency and lifespan, saving you money on bills and repairs.

This system features three-stage filtration: a polypropylene sediment filter, a GAC filter, and a CTO filter. The sediment filter removed dust, dirt, rust, and other debris from the water. The second stage filter, the GAC, filters out chlorine, radon, VOCs, and other harmful chemicals, while the CTO carbon block filter eliminates pesticides, insecticides, and industrial solvent, as well as odors and bad tastes.

This system also comes with 3 pre-installed filters and one extra filter set. Filters need to be changed every 3 months. Luckily, the replacement filters are inexpensive and easy to find.

But guess what:

Unlike some other systems, this one is also extremely simple to install. And with the see-through housing, you can take a peek inside and know when the filters need changing. However, our research showed that, when this system is installed, sometimes the water pressure drops. So consider this system only if you have strong water pressure.

If you want to know the quality of your water, you might want to invest in HM Digital Water Quality TDS Tester. It’s a popular add-on among owners of water filtration systems because it’s an inexpensive, but precise item. Its microprocessor technology allows it to be very efficient, measuring from 0 to 9990 ppm. The results can easily be read off of the large LCD screen, but this gadget also allows you to save measurements with the hold function. The item shuts off automatically after 10 minutes of non-use to preserve battery life.

Features:

• Whole house filtration system
• 5-micron filtration
• 3-stage filtration
• Polypropylene sediment filter
• Quality GAC filter
• CTO carbon block filter
• 1/2" port connection

If you’re on the lookout for a whole house filtration system, this iSpring system is a good choice. The company is a reputable one, and our research showed that they sell high-quality items. This system provides sediment and chemical filtration which gives you clean and healthy water.

This iSpring system is easy to install, thanks to the built-in frame, and our research has shown that the complete installation takes less than two hours. The company also provides DIY installation videos on YouTube, to make the process even simpler.

The iSpring whole house system uses three stages of filtration. During the first stage, the high-quality polypropylene sediment filter catches dirt, rust, silt, and various other sediment particles. The second stage utilizes the coconut-shell carbon block filter which removes chlorine and other chemicals from the water. The third stage purifies the water further by running it through an even finer filter, thus removing residual chlorine, odors, cloudiness, colors, etc.

It gets better:

This means that, when using this system, as much as 95% of sediment, chlorine, pesticides, herbicides, and various other contaminants are removed from the water. Also, while researching this system, we have noticed that many users report that their water pressure isn’t reduced, which is a common downside when installing some other filters.

This system has a capacity of 500 gallons per day, which means it’s perfect for households of a small to medium size. The filters have a standard dimension, which makes them easy to find, buy, and replace when the time comes. The system also features a pressure release valve, which makes installing and replacing filters even easier.

All in all, this is a very good filtration system, but our research did produce a few downsides. Namely, if you have bacteria, viruses and other microorganisms in the water, you should know that this system doesn’t remove them. However, many people buy an iSpring UV disinfection system to handle that issue. See more about a compatible UV sterilizer – the iSPring #UVF55 below.

Also, some users have reported that the system sometimes leaks. The company is very responsive and quick to send replacement parts, but it can still be a hassle.

A common add-on for this product is iSpring Whole House UV Disinfection System. If you want to remove bacteria from your water, this UV sterilizer goes along perfectly with the iSpring whole house filtration system. It uses UV light to eliminate bacteria, viruses, and protozoan cysts from the water.

Features:

• Whole house filtration system
• Sediment filtration
• Chemical filtration
• Dimensions: 20 x 4.5 inches
• 500 gallons per day capacity
• 5-micron filtration
• 3-stage filtration
• Polypropylene sediment filter

• Pressure release
• 1-inch inlet/outlet
• DIY installation video

The Home Master HMF2SDGC is a great whole house water filtration system perfect for those using city water. Our research shows that it’s easy to install, and most people don’t need the help of a professional. Instruction manual is included with the product.

This product features 2-stage filtration, which means it includes two filters. The first filter is a multi gradient depth polypropylene sediment filter. This filters catches dirt, rust, silt, and other sediments. It has four layers with 25, 10, 5 and 1 microns, so it captures even the smallest particles of sediment in your water. It’s also resistant to bacteria and chemicals and has a huge dirt holding capacity.

The second filter is an activated carbon filter made from coconut shell with radial flow. It removes various chemicals including chlorine, and helps with the taste and odor of your water. It’s made with high-quality coconut shell and carbon contact time is lengthened, so your water comes out as pure as it can be.

This system features oversized filters, housings, and one-inch ports. This can ensure that your water pressure always delivers! One of the best pros of this system is that the filters don’t need maintenance and they only need to be replaced approximately once a year.

And when the filters need replacing, getting new ones is a breeze. For the 1^st stage filtration, this Home Master Sediment Filter is a great choice. It fits this system perfectly, also have a life of approximately 12 months, chemical and bacterial resistance, and a huge holding capacity.

And the Home Master Radial Flow GAC is a perfect fit as a 2^nd stage filtration replacement filter. It’s easy to install, and doesn’t hurt your water pressure (<1 PSI pressure drop).

The system comes with everything you need to install it – mounting bracket, wrench, ports, etc. It also features a 2-year limited warranty.

But here’s the deal:

Unfortunately, this system will not eliminate bacteria and other microorganisms, so if you have these in your water, it’s important to select a system with a UV or bacteria elimination stage. Also, the ports which come with this system are plastic, and we’ve found that, when installing the system, getting a tight seal might be a bit difficult.

Features:

• Dimensions: 22.5 x 14.2 x 12.9 inches
• 20 GPM
• Big housings
• 1-inch ports
• Gradient density filters
• 1 micron filtration
• 100,000 gallon capacity
• Inlet/outlet ports don't restrict water pressure
• Includes mounting bracket
• Includes bolts and wrench for installation
• Includes installation instructions
• 2-year limited warranty

The HQUA-UV-12GPM is a great purifier if you’re on the lookout for a quality ultraviolet water purification system. Our research showed that these systems can ensure the water in your home is clean and drinkable. HQUA is a reputable company with exceptional customer service, and this model is a top choice when it comes to UV systems.

Our research has shown that one of the best features of the HQUA-UV-12GPM is that it’s very easy to install. Although it comes disassembled in a box, the parts and assembly are intuitive, even for a beginner. There’s also a handy instruction manual that comes with the product.

When you order the HQUA-UV-12GPM, the box contains the chamber made from stainless steel, two UV bulbs, and a protective quartz sleeve. There are two O-rings, two plastic brackets, and a 55-watt electronic ballast with a standard three-prong plug.

Here’s where it gets good:

Unlike standard filtration methods which can include chlorine or other chemicals, this system doesn’t add anything to the water – it’s completely free of chemicals. It uses UV to purify the water. Of course, this means it doesn’t affect the makeup of the water in any way, apart from removing bacteria and germs.

A potential downside to this filter is that water quality is important for its performance – it requires water with little amounts of iron, manganese, and tannins, a specific hardness, etc. We’ve found that it’s recommended to have a 5-micron filter in front of this one to prevent particles from covering the tube.

If your home has pre-filtered water, this filter can be a great choice. But the HQUA-UV-12GPM isn’t a great system for homes which have problems with dirt, sand, rust, and other residue in the water, as it won’t remove any of the undesirable particles and they will influence its effectiveness. You can buy additional filters to complement this one – we’ve found that the DuPont Cartridge and DuPont Filtration System are great choices.

However, many customers who have tainted water and have failed numerous bacteria tests (coliform, E-Coli, etc.) claim that this filter solved their problem efficiently. So if the only problem is bacteria in the water, this system is a good choice.

Our research showed that, when compared to other similar UV filtration systems, the HQUA-UV-12GPM is extremely fast, purifying water at a rate of 12 GPM (gallons per minute), which is awesome if you have a quality kitchen faucet. It’s also incredibly durable, with the UV tube made to last at least 9000 hours. This package also includes an extra tube.

When it comes to maintenance, this filter doesn’t require much. The quartz sleeve needs to be cleaned out approximately once every eight months, and the UV lamp should be replaced yearly.

But we’re not quite done:

There are two awesome add-ons you can get to complement your filtration system. DuPont Universal Whole House 2-Phase Cartridge reduces chlorine, rust, dirt, and other particles in the water, thus increasing the clarity and quality of the water. Our research showed that it extends the life of appliances, and can be the pre-filtration that will complement the HQUA-UV-12GPM. This product includes two cartridges, each with a lifespan of three months.

There’s also DuPont Universal Whole House 15,000-Gallon Filtration System. This simple water filtration system increases water clarity by removing sediment and various particles from the water. It can be used along with the HQUA-UV-12GPM and comes with a 3-year Limited Warranty.

Features:

• Dimensions: 37.2 x 2.5 x 2.5 inches
• Weight: 7.9 pounds
• Voltage: 120 volts
• Wattage: 55 watts
• Flow rate: 12 GPM
• ¾-inch in/outlet
• No secondary pollution
• 9000 hours of life of UV bulb
• Detailed instruction manual included
• Extra UV tube included

If you’re looking for a great whole house filtration system, the Home Master HMF3SDGFEC is a quality choice, especially if you’re using city water which is full of chemicals, iron, and dirt. When we researched this system, we’ve found that installation is easy and simple – not many people need the help of a professional plumber. The installation manual is easy to read and follow.

This Home Master whole house filtration system features three-stage filtration. This means that the system includes three separate filters. All of the filters are durable, high-quality, and require little maintenance.

Let’s take a closer look:

First, there’s a huge multi-gradient depth sediment filter made from quality polypropylene. Its main purpose is to eliminate dirt, silt, rust, and other sediment from your water. It’s multi-gradient, which means it features multiple layers of filtration, in this case it has four layers. The shell filters up to 25 microns, followed by 10- and 5-micron layers, and the 1-micron core gets rid of even the smallest particles.

The second filter featured in this system is a specialized iron filter. It’s a radial flow filter which gets rid of iron in your water up to 3ppm! So if you have iron in your water, this phase is a must. It also helps with hydrogen sulphide and manganese.

The third and final filter in the system is a carbon filter. Made from high-quality coconut shell, this filter features radial flow, and it eliminates various chemicals from your water. Our research showed that it effectively removes any unnatural tastes and odors from the water it filters.

However:

One of the cons of this system is that it won’t get rid of microorganisms. Also, some users complain that the ports featured in this system are plastic, and when we did research on that, it showed that getting a tight seal on the system might be a bit difficult when installing it.

On the other hand, all the filters in this system are specially designed not to reduce water pressure. Also, the filters are oversized, which means you only need to change them approximately once a year!

And when they do need replacing, it’s easy to get new ones. The Home Master Sediment Filter is a quality choice as a first-stage replacement filter. It’s designed for this system, so it also lasts for approximately 12 months, and it’s easy to install because it fits the system perfectly.

For the second stage, the Home Master Radial Flow Iron Reducing Filter is a great replacement choice. It does everything the original filter does and is easy to install. The Home Master Radial Flow GAC is a good choice if you need the third-stage filter replaced. It’ll fit perfectly and won’t interfere with your water pressure. Our research shows that it only causes a <1 PSI pressure drop!

Features:

• Dimensions: 24 x 9 x 25 inches
• 15 GPM
• 90 PSI
• Gradient density
• 1 micron filtration
• 100,000 gallon capacity
• 1-inch inlet/outlet ports don't restrict water pressure
• Includes mounting bracket
• Includes bolts and wrench for installation
• Includes installation instructions
• 2-year limited warranty for parts

Many people live in areas which are affected by hard water and high iron quantities in the water. Luckily, there are great water filters designed just for those issues. The IRON Pro2 is a high-quality system which removes sediment and metals and softens the water in a household.

Water softeners are used to eliminate hard minerals, which can inconveniently cause build-up in pipes and faucets, as well as lower the longevity of home appliances. The IRON Pro2 does that very efficiently, and it requires little maintenance.

This system also eliminates iron, manganese, and other metals from the water. It’s a good choice for areas with very hard water and high metal content because it can handle high quantities of both with ease. It can handle up to 8 ppm of iron and 6 ppm of manganese.

This is crazy:

This filter isn’t just very versatile when it comes to contaminants it eliminates. It’s also highly efficient due to its meter based regeneration feature. Basically, the system measures water usage and only regenerates when needed. When less water is being used, it regenerates less, thus conserving water.

The filter comes with a digital control system, and programming the system is extremely easy. Note that you will have to know what the water hardness is, what the system capacity is, and what the water usage would be. Installation is also simple, with all the tools and instructions provided, and it takes about two hours.

This filter is designed and sold by Fleck, which is a prominent company that has been producing quality water softeners for years. They are known for their high-quality customer service, and our research confirmed that they are available and always happy to help. They also provide great warranties – the IRON Pro2 has a 10-year warranty on the tank and a 5-year warranty on the control head.

The only downsides we could find are that the system is not suitable for very large households. So if there are more than eight people in your home, it’s better to opt for a more powerful system. Also, the installation lines aren’t included in the package.

Features:

• Water softener
• Iron filter
• Dimensions: 13 x 54 inches
• Flow rate: 18 GPM
• Capacity: 80,000 grains
• Fine mesh resin
• Digital control system
• Can handle hardness up to 85 gpg
• Can handle iron up to 8 ppm
• Can handle manganese up to 6 ppm
• Eliminates scale build-up
• 18 x 40 brine tank included
• Bypass valve included
• DIY Installation video provided
• Control Head – 5-year warranty; Tank – 10-year warranty

The Aquasana Whole House Water Filter is a filtration system which purifies the water in the entire home and removes microorganisms, chemicals, and sediment. It’s a great system for eco-friendly filtration.

This system features pre- and post- filters and sub-micron filtration, which makes it extremely effective in removing all kinds of unwanted particles from the water. This includes pesticides, herbicides, dirt, rust, silt, sediment, heavy metals, industrial solvents, and more. It’s a complete system for purifying all the water in your home and making it clean, healthy, and safe.

The Simplysoft salt-free water softener featured in this system softens water but doesn’t use chemicals or salt. This means it’s great for preventing scale formation, and protecting the pipes and plumbing of a home. Also, the system won’t negatively affect the environment because it doesn’t add excessive amounts of sodium into the communal water system.

But it gets even better:

This system also includes a UV Sterilight filter which uses UV light to eliminate 99% of bacteria, viruses, and other microorganisms like E. coli, giardia, and cryptosporidium from the water. The Aquasana system lasts for 10 years, or one million gallons and the package includes a pro installation kit. However, the kit doesn’t include PEX tubing.

All in all, the Aquasana system might seem like a great choice, but our research has shown some troubling potential cons. Although many users have reported that the system functions perfectly, many people also complain that the system starts leaking and malfunctioning around the 2-year mark. We’ve also uncovered that the company seems to be aware of the pitchers’ tendency to leak, but haven’t found a solution.

The system also sometimes causes water pressure to drop unexpectedly. The fittings and tubing is plastic, so it’s prone to leaking. Also, note that the filters need to be changed every two to three months.

Many users also have problems taking advantage of their warranty, with the company being unresponsive or dismissive when issues are brought up. Very bad customer service is often brought up by people who have installed the system. Also, the company will only warranty if the system is set up by a licensed plumber, and the cost of installation is usually around two-thirds of the cost of the system itself. This means that in reality, the total cost is even higher than anticipated.

Also, customers that use bleach while washing clothes or doing chores have reported that the Aquasana system turns their water brown when bleach is used. The installation of the system is fairly complicated, and although the installation kit and instructions are provided, a professional plumber might be needed.

So even though the system works perfectly for some users, and they have reported being very satisfied, our research shows that purchasing this system comes with its risks.

Features:

• Dimensions: 9 x 46 x 69 inches
• Whole house water filtration system
• Removes microorganisms, chemicals, and sediment
• Flow rate: 7 GPM
• Filter life: 10 years
• UV Sterilight filter
