Best Whole House Water Filter – Reviews, Awards, and Discounts 2021

---

When we reviewed the best water filters of 2021, we saw that most people were after systems that provide filtered water for the entire home. That makes sense, as water contaminated with lead, chlorine, or other minerals usually causes a foul food taste, weird water odor, and issues with the hair and skin. By purchasing a whole-house water filter, you’ll ensure that each member of your family gets to drink delicious water, cook tasty meals, and have showers that leave them as refreshed as possible. Of course, you can also tackle all those issues by buying separate shower filters, faucet filters, under-sink filters, or even countertop filters. If you live in extreme conditions, a portable filter or a filter pitcher is also a clean water alternative.  

While that is an option worth considering, nothing will make you feel more at ease than a whole-house filter. Needless to say, you’re going to spend some extra bucks on setting the whole thing up, but we can honestly say that the by-product will be more than worth it. Below, you will find a list comprising of the nine most renowned whole-house water filters of 2021. We have picked these products via a screening process that emphasized reliability, long-term duration, performance, and most of all – price. We tried including numerous units, various filtering methods, and different price ranges, so everyone can find a system that perfectly matches their needs. Without further ado, let’s see what the market has to offer.

Best Whole-House Water Filters of 2021

1. Pelican Premium Whole-House Filter System ($759)

First, we must let you know that Pelican manufactures two systems for different bathroom capacities. The first one is made for one to three bathrooms and can sustain up to 600,000 gallons of water, whereas the second suits four to six bathrooms and satisfies up to 1,000,000 gallons of filtered water.

In our water pitchers review, we discussed that many manufacturers put false claims in their water treatment units. The best way to prove their genuineness is to see whether they’re certified by relevant agencies. Pelican is among the very few brands that not only carry the NSF/ANSI seal but showcase the authentic documents containing the full list of contaminant removal rates. You can learn more about this in our Pelican filters review, but here, we can tell you that this water filter is certified to remove about 97% of chlorine from drinking water. To do this, the Pelican filter utilizes a 5-micron filter that combats even the smallest and most stubborn water contaminants to absolute perfection. This filter is also great for hard water, as it prevents scale build-up on your plumbing and other fixtures. 

2. Springwell Whole-House Water Filter System ($811)

This, in turn, causes the filtration elements to combat the contaminants more roughly, which then equals cleaner water. This procedure is done on four separate stages, so excellence is inevitable. 

First, the contaminated water goes through the KDF media that is specially made for removing larger particles found on municipal water. The spotlight here falls on chlorine and chloramines, as they are the main chemicals used in city water disinfection. The treated water then goes to the coconut-shell carbon that removes any remaining elements like VOCs, pesticides, and herbicides. In stage three, the whole-house filter utilizes a pressurized system that prevents water channeling and ensures that all significant elements are removed from the filters. In the last step, Springwell features a 5-micron sediment filter that identifies and removes any remaining sand, silt, clay, or other dirt formations for the ultimate filtration.

Besides being certified by the NSF for the effective removal of water pollutants, Springwell is also renowned for using state-of-the-art components in its filtering mechanisms. This means that while the whole-house water filter will treat the water as efficiently as possible, it will also ensure that the system is there for you in the long run. To take water protection to the next level, you can also attach a Springwell UV protection unit. The Springwell filter also has three models to choose from, all of which come with different flow rates. The 1-3 bathroom model supports a flow rate of up to 9 GPM, the 4-6 bathroom unit can sustain up to 12 GPM, whereas the 7+ bathroom system will boast about 25 GPM. The system itself is straightforward to install and is supported with a lifetime guarantee on all its parts & labor. As of now, the Springwell whole-house water filter has over 300 reviews and a 4.9 score. 

3. Aquasana Rhino Water Filter System ($799)

Indeed, the Aquasana Rhino filter is certified by the NSF for significantly reducing chlorine, different types of heavy metals, herbicides, pesticides, organic chemicals, VOCs, and many industrial solvents. Another advantage to this Aquasana filter is that it does quite a lot of favors to your air quality since it removes the hard water minerals evaporated from your steamy showers. If you’ve noticed a slimy texture in your shower curtains or an odd smell coming from them, then you ought to be pleased to know that Aquasana will most definitely make that a problem of the past. As a result, your home will get a transformed water quality that will promote tasty drinking water, fresh breathing, better cooking, brighter clothes, restored skin and hair, and most importantly – overall better health.

4. Aquaox 7-Stage Whole-House Filter System ($2,999)

The secret behind Aquaox’s premier whole-house filter is that it utilizes a seven-stage procedure to eradicate contaminants from your water supply completely. First, the “dirty” water flows through a sediment pre-filter that removes the larger particles of pollutants, whether the water is from a city or well water source. Then, the water enters a catalytic carbon media that remove sulfides, iron, and chloramines. In the third stage, the water is taken on a KDF ride that removes chlorine, bacteria, algae, and any remaining iron parts in the water. After most of the damage is done, the whole-house filter system utilizes a coconut carbon shell media that is specially designed to tackle foul taste and odor, pesticides and herbicides, and other contaminants like pharmaceuticals out of your water supply.

Where things get really interesting is the filter system’s garnet media tank that starts and concludes the fifth stage of water filtration. Here, the water is rid of total suspended solids, some of the more hard-to-remove pollutants in nature. Garnet media is quite hard to get a hold of, but luckily, brands like Aquaox and Clack have managed to utilize them for their water filtration units. In the sixth stage, the brand’s whole-house filter features a filter AG that prevents screening to a maximum and removes any remaining dirt particles. In the seventh and last stage, the whole-house filter initiates a backwashing cycle that cleans the system up and ensures that its next session will be as practical as ever. To help you make the decision, Aquaox has warrantied its fantastic device with a 10-year no-hassle warranty and a 20-year premium performance guarantee. Right now, the system holds a 4.8 review score. 

5. iSpring 3-Stage Filter System ($469)

Moreover, the water filter has a 95% efficiency rate of removing sediment, rust, VOCs, industrial solvents, herbicides, pesticides, and everything in between. For those who want a mid-range product that does it all and then some, iSpring is the way to go.   

To install the whole-house filter system in your home, all you’re going to need is a little bit of willpower and iSpring’s installation manual. People love this filter system so much because it is completely DIY and has little no maintenance. The iSpring whole-house filter also causes the smallest impact on a house’s water flow, as it can hold up about 15 GPM of consistent flow. The space-saving filter system has a capacity of 100,000 gallons of water, which will supply the average US family with clean water for about a year. Besides the filters that do most of the work, iSpring has also used high-quality parts in constructing all features of this water filter. That’s why the US-based brand has the agency to say that while the unit may last for just a year, the customer satisfaction will go on for a lifetime.

Considering that this whole-house water filter uses a multi-faceted approach, we can safely say that no contaminant is safe from its screening process. The filtration process begins by utilizing a polypropylene pre-filter with a 5-micron texture for the maximum contaminant removal. Here, the whole-house system removes bigger particles like sediment, silt, dust, and rust, and by doing so, protects the unit from damage. In the second and third stage, the water goes through a CTO carbon-block filter that not only enhances the system’s efficiency but extends its filter’s life too. This stage is where most magic happens, as the water system carefully pinpoints each polluted element that needs to be taken apart from the clear water particles. The iSpring unit will also retain all the beneficial minerals in the water, so the end-product will taste delicious, feel smooth, and look healthy. In Amazon, this product is currently rated at 4.5 stars, whereas on its 123 Filter it has a 4.8 review score.

6. ProOne Standard ProHome Filter System ($1,799)

However, we’ve concluded that the ProOne Standard filter is entirely capable of doing a good job, and its extensions are mere tools to be used in regions with specific pollutants. But what exactly makes the ProHome as good as we say? 

For starters, the whole-house water filter has a great filtering capacity, as it is NSF-certified to remove up to 100,000 gallons of chlorine and up to 50,000 gallons of other contaminants. Among those, ProOne names non-organic acids, disinfectants, VOCs, water cysts, herbicides, pesticides, pharmaceuticals, and heavy metals. To do this, the system’s manufacturers have used the ProOne G2-0 filters that are entirely known in the water treatment industry for their excellent efficiency in contaminant removal. The next “big thing” of this system also includes the sub-micron post-filter, which is an electrically-charged filter that does wonders for the polluted water. The ProOne Standard whole-house filter is suitable for both city and well water supplies, but depending on your location, you may need a water softener too. Luckily, ProOne has its range of saltless water conditioners to match the ProHome system perfectly, so you won’t have to scour the web for alternatives.

Like most “pricey” filters, the ProOne system also favors a remineralizing scheme. This means that while the “bad guys” in your water are extracted, the “good guys” are left in there. Another fantastic advantage is that the whole-house water filter is incredibly cheap to maintain, as it will only cost you an average cost of four cents per gallon. The ProOne filter also requires no electricity or drainage to run, so you’ll save thousands of dollars from maintaining the device properly. Unfortunately, the brand’s website doesn’t have a review section for assessing the customers’ satisfaction.

7. Whirlpool Central Home Filtration System ($479)

This process is programmed to happen once every two weeks or so, which means that you won’t have to interfere with the system’s maintenance for as long as the whole-house filter unit functions in your home.

Besides the undeniable advantage of maintenance-free use, this water filter system is also great for many other reasons. First, we must note that the Whirlpool filter is made of high-grade components and premium filter elements, a fact that is even more fascinating when you consider the system’s budget-friendly price. Moreover, this filter system is certified by the NSF to remove dozens of contaminants from city or well water supplies, so you can perfectly match the system for your living situation. What’s even more interesting is that Whirlpool is certified to remove particles as small as 40 microns, so no chlorine, pesticide, herbicide, VOC, water cyst, or heavy metal element is safe. The unit’s filter parts are safely locked in, so you won’t have to worry about any health hazards or eventual leakage on Whirlpool’s end.  

8. Tier1 Eco Series Water Filtration System ($761)

Now, the water filter lies all its trust on the system’s KDF media that goes above and beyond, so you and your beautiful family will get to have clean water wherever and whenever they want to. This media can reduce many contaminants like heavy metals, chlorine, mercury, lead, herbicides, pesticides, VOCs, pharmaceuticals, and more. Moreover, the system’s activated granular carbon will place the final nail in the coffin, as its joint effort with the KDF media will produce deliciously-tasting water that prioritizes good health. If you want to adapt the whole-house water system for your well water source, you may have to opt for an additional pre-filter that will also take care of sediment and dirt; or a water conditioner that will tackle hard water issues. For more about that, you can check out our softeners guide.

All in all, the Eco Series filter system is ideal for larger homes and small commercial purposes, as it holds an excellent and consistent water flow and doesn’t interfere with your house’s existing water pressure. What’s most favorable about this water filter system is that the Tier1 unit will come self-contained and pre-loaded with the media filter, so it’ll be ready for you to use as soon as you take it out of the package. The brand has also included all the fittings, valves, and mounting brackets, which – when combined with the easy-to-read instruction manual, will turn the unit’s installation into a walk in the park. After all is said and done, Tier1 guarantees that your water will be completely cleared of all those awful tastes and odors, dissolved minerals, microorganisms, sediment, and turbidity. This system is currently rated at 4.9, but we’re unsure whether the reviews are from confirmed purchases.  

9. GE Appliances Whole-House Filter ($69.99)

To install this system in your house, all you’re going to have to do is utilize its plumbing connection, pressure-relief valve, and mounting bracket – all of which are included within the package. The whole-house water filter also has a filter indicator, so you’ll always know beforehand that your system needs a change. According to the manufacturers, this filter will last the average family for about three months, which is more than what GE’s competitors have to offer. GE advises using genuine replacements for the optimal filtration results, but many customers have noted that third-party ones work just fine too. Water Whizz has also covered some of the best replacement filters on the market, so make sure to check that out.
