Looking for the best whole house water filter 2021? Good! We’ve assembled a comprehensive, far-reaching guide for you. We hope that by the time you’re done reading this article, not only will you be in a position to pinpoint a water filter that suits your household needs but also know what a good water filter should look like. In short, we’ve done extensive research to make this your to-go-to resource for anything and everything you’d need to create the best whole house water filtration system for your home.
Before we take a look at the top-rated water filters for your home, let’s start with the basics. According to the United States Environmental Protection Agency (US EPA), up to 85% of the US cities use hard water. In fact, if you’re reading this, there every chance you live in a city or state with a high prevalence of hard water. By extension, this means that the water in your home contains high levels of minerals such as dolomite, chalk, and fluoride. While this water isn’t dangerous to drink, the accumulation of lime-scale in your water pipes can lead to corrosion and blocked sewage lines. Plus, hard water doesn’t lather easily. It, therefore, makes perfect sense to invest in a filtration system that will get rid of the minerals, doesn’t it?
… So, why a home water filter?
Sure, there are other methods of home water purification such as reverse osmosis, lime softening, distillation and using an ion-exchange device. However, these are relatively expensive and time-consuming. The primary reason for using a home water filter is the ability to get rid of impurities at a fraction of the cost. But, it goes without saying that you have to install an efficient, reliable, high-performing water filter – which brings us back to the first point at the beginning of this write-up. What follows is a rundown of ten home water filters with proven capacity to all of the above and more.

Home Master makes a return to our whole house water filters reviews, this time with the HMF3SDGFEC.

Expect finer filtration with this model down to 1 micron. Another unique highlight is the fact that this unit doesn’t sacrifice water flow. In fact, it can handle a remarkable 90 psi of pressure.

The iSpring WGB22B is a brilliant point of entry filtration system. However, unlike other similar reverse osmosis models that have to be installed to a particular faucet, this one filters your water right from the source. Put differently, water from each and every output in your home will have undergone two filtration stages before you can use it.
In the first stage, the iSpring WGB22B gets rid of dirt and large particles down to 5 microns using the high-capacity polypropylene sediment filter. The second carbon block filter removes targeted contaminants, tastes, and odors. It also eliminates up to 90% of chorine. Also, this unit is highly efficient on herbicides, industrial chemicals, and pesticides.
What we’re trying to say here is that the iSpring WGB22B will serve you well if you want to purify highly contaminated or chlorinated water. It will also come in handy if you get your water from a well and want to remove heavy metals such as lead and iron. It will filter up to 100,000 gallons of water before you need to replace the cartridges. Now, that’s an equivalent of one year of clean water for your family.
Other than that, the WGB22B can handle a water flow rate of up to 15 gallons per minute. Those who’ve used it say it has enough output for a high flow kitchen faucet and up to two bathrooms. While this is not the best of performances, it is adequate for day to day purification needs. Keep in mind that this is a two-stage filter, so that explains its capacity. And to top it off, it comes at a competitive price.
APEX did its homework on this one. A well-rounded whole house water filter, the MR-3020 comes with multi-stage 20-inch housing. It features a one-micron filter pad, a Granular Activated Carbon filter, and an Activated Alumina cartridge. With such a combination, it can effectively remove arsenic chlorine, fluoride, heavy metals and a variety of other contaminants from your water.
The MR-3020 also has an NSF approved, high-performance coconut shell complete with carbon filters to absorb by-products such as TCE and THM. And then there is the 20 in sediment filter that sieves deposits such as rust down to five microns. It will reduce fluoride up to 93% as well.
While the MR-3020 is relatively small, its wide cartridge design allows it to meet the demands of condos, large homes and apartments with ease. It is a great filtration system for a busy eatery or medical facilities. We love the unique cartridges, engineered to serve for at least six months, thereby reducing maintained frequency.
For those who may want to know, the MR-3020 comes with all filters included – all you have to do is to fit into place and you’re good to go. It measures 28″x22.5″x9″ and can handle a water pressure of anywhere between 80 to 90 psi. For the best results and optimal filtration, be sure to keep the flow rate at 5 gallons per minute. The only thing you need to note with this system is that it doesn’t come with mounting hardware but that’s by no means a deal breaker.
There is every reason to vouch for the Watts WH-LD. For one, it is ridiculously affordable and as if that’s not enough, it comes in a pack of three! And, different from any other model on this list, each filter has a clear housing. What does this tell you? Well, it means that you can see the dirt and sediments being filtered. Most importantly, you’ll always know when the filters are due for replacement.
The Watts WH-LD touts metal threaded inserts (3/4 inches), a good alternative if you don’t like plastic fittings. Don’t worry if the water in your house requires filtration for a host of chemicals. This unit uses 10 by 25 inches filters so you have the freedom to choose filters that work as per your needs beyond the manufacturer-branded ones. We love the integrated valve bypass which makes filter change super easy. In fact, you don’t have to turn off the water flow or install separate valves on your pipes to keep the water flow under control.
The Watts WH-LD can operate at a maximum pressure of 100 psi, more than any other model on this roundup. The maximum operating temperature stands at 100 degrees Fahrenheit. Indeed, this is a one stage filtration system but it could very well be the only filter you need for your home. In gets rid of everything from large particles to chlorine, chemicals and everything in between. Even then it doesn’t come with a mounting bracket so keep that in mind when purchasing.
Wrapping up our best whole house water filter reviews is this model by APEC. A premium 20-inch model, it strikes a combination of both durability and versatility required to meet your large capacity filtration needs including heavy sediments and high flow application. When working at its optimum, this unit will give you filtered water up to 70,000 gallons with only one replacement required every 12 months.
The APEC features a radial flow granular activated carbon filter cartridge to eliminate organic contaminants and improve your water’s taste. And just as you’d expect it doesn’t affect the flow rate or drop pressure of the water coming out of your faucet.
While its performance isn’t in doubt, the other thing that makes the APEC special is the leak-proof design. Unlike most models with a relief button that requires frequent replacement to reduce leakages, this one comes with a reinforced polypropylene cap that’s completely leak-free. It even has a standard 1 inch FPT pour that makes it compatible with copper plumbing and other conventional PVC pipes.
Plus, every package comes with a wrench and bracket of convenient installation. With what this has to offer, we reckon that the APEC is a perfect water filter for a mid-sized family, beverage shop owners and a small restaurant. It is also a good option if you’re a gardener in search of a unit that can give contaminant-free water for your garden, trees, and flowers. Plus, it comes at a cost that won’t leave a whole in your wallet.
How to Choose a Whole House Water Filter (Buyer’s Guide)

In other words, you’ll spend a significant amount of money so you’d better be sure the model you intend to purchase doesn’t fall short when it comes to capacity.

You see, any filtration worth your money should do exactly what you expect it to do. You’re better off with a model that can rid of as many contaminants as possible. You have to be sure that the unit can eliminate pollutants such as chlorine, fluoride, heavy metals and so on. The last thing that you want is to invest in a high-end water filter only to discover that it can’t get rid of some contaminants.
The Flow Rate
Again, a good water filter shouldn’t affect the flow rate of the water coming out of your faucet or any other points. It shouldn’t lower the pressure. Some models such as the Express Water Whole House Water Filter System come with an integrated gauge that allows you to see the rate at which your water is flowing. All in all, mounting a filter in your home shouldn’t in any way mean that you should compromise the rate at which your water was previously flowing.

You need to know that the water filter you’re planning to use is safe for use. Be on the lookout for NST international and Water Quality Association certification. That way, you can rest assured that indeed the filter has been certified to get rid of contaminant and most importantly, using it will cause no harm to your health.
A Filter Change Indicator
Needless to say, your system will only remain effective if you replace the filters within the required time. The best unit, therefore, should have a mechanism that reminds you when that time comes. Some models such as Watts WH-LD come with a clear casing so you can know exactly when to change the filters.
A Variety of Compatible Attachments
The best water filter should be compatible with other attachments that increase its efficiency. Take the Aquasana, for instance. This unit supports UV filtration, increasing the percentage of the bacteria that it kills. It uses a variety of filters to increase the time it takes to replace them and the filtration capacity. In short, you’re better off with a system that allows you to customize it to fit your needs even more.
…In addition, ask yourself;
What contaminants am I dealing with?
All water isn’t the same in terms of pollutants. You need to identify the specific contaminants in your area to determine if a particular water filter is best for you. You can easily know the status of the water in your area of residence by visiting the United States Environmental Protection Agency official website.
How much water do I need to filter?
As you may have already noticed in our water filter reviews above, different models have a varying filtration capacity. You have to interrogate the unit you want to purchase capability to handle your every day needs. If you don’t require a lot of purified water, then you may choose an affordable model and vice versa.
How often will I have to change the filters?
Just like any other appliance, a water filter requires regular maintenance to keep it in a good working condition. Mostly, whole house water filters need consistent changing of filters and cartridges. If you don’t want to spend a lot of money on maintenance cost, then you should choose a model that comes with long lasting filters. Some units can go an entire year without the need for a replacement.
How easy is it to install the filter?
You have to mount your water filter correctly if you want it to work well. While we recommend finding a plumber to do the installation on your behalf, you should consider a unit that easy to install with little help. Remember, you will have to replace the filters later on and you don’t want to keep calling your plumber every time you need to do so. Note – some manufacturer may render the warranty and its specifications void if you don’t use a professional plumber to do the installation.
