Best 5 Whole House Water Filter Systems: Finding the Right One

Just imagine turning on any tap in your home and getting pure, filtered water—whether you're filling a coffee pot, taking a shower, or running the washing machine. That's the promise of whole house water filtration systems.

A study published in Nature's Journal found that over 43 million Americans rely on private wells for their water supply, which receive no federal water quality monitoring.

Choosing useful water filter systems have become increasingly important, as water quality concerns rise nationwide.

Our team tested the most popular whole house water filter systems this year. We will help you find the right system for your home's specific needs and budget.

My team tested and installed 9 whole-house systems and monitored water quality at every faucet - kitchen, bathroom, laundry room, even outdoor spigots. We tested at maximum usage when multiple showers were running simultaneously using flow rates.

With 20+ years of experience, I knew to consider oft-underappreciated parameters like pressure drop and serviceability. We tested on city and well water and monitored how each system held up on differing contaminants.

Finally, we select the 5 best systems for American families. each excelled in a specific application- chloramine removal on city water, or iron and sulfur treatment on wells.

Our Use Experience

The Kind E-1000 is a great option if you desire advanced performance at a lower upfront cost.

The water quality is enhanced immediately—there are no chlorine odors and it is much cleaner-tasting.

It’s an intelligent design move to keep those recurring expenses minimal. Though you will have to change out cartridges more frequently than you would with a tank system, it is done quickly and with no tools necessary.

The system works silently and reliable and is a wonderful first filter for municipal water to reside with day by day. Just remember its dual canisters need some wall space.

Best for: Households on city water that desire comprehensive chlorine, VOC, and THM reduction, along with a salt-free solution for hard water scale.

Why choose it:

• The system features a salt-free (TAC) process to reduce hard water scale
• It effectively removes chlorine, chloramines, VOCs, industrial solvents, sediment, rust, THMs, and taste/smell compounds
• With a 12 GPM flow rate, it delivers steady performance for most mid-sized homes
• Its KDF layer helps keep the tank media fresh longer

Our Use Experience

The Aquasana EQ-1000 is a heavy-duty system and is definitely worth doing chlorine reduction for. The water smells and tastes significantly better and the KDF filter works great at keeping the tank clear and residue-free.

While saltless scale prevention is somewhat less quantifiable, I’ve discovered fixtures and glassware are cleaner and reduce the effort involved with scrubbing out mineral deposit buildup.

The main tank will keep for years, and that's excellent, but you'll want to switch out the pre-filter every few months.

Just keep in mind the warranty is installation type based with 10 years for pro installation and 1 year DIY

Best for: Budget-conscious homeowners on city water looking for a simple, effective, 3-stage filtration system to tackle chlorine, sediment, and mild iron or manganese issues.

Why choose it:

• This 3-stage system removes up to 99% of chlorine, along with sediment, rust, tastes, odors, herbicides, and VOCs
• It includes a specific filter stage for iron and manganese reduction
• It boasts a strong 15 GPM flow rate
• The system is designed for easy DIY setup

Our Use Experience

The iSpring WGB32B is a no-frills, reliable workhorse for cleaning up city water.

Our tester used a similar iSpring model on his well water (with light contamination), and it performed admirably, eliminating strong chlorine odors, improving clarity, and even helping with mild iron stains.

While it won't solve all well water problems or remove emerging contaminants like PFAS or fluoride, it excels at the basics, providing a decent flow and much-improved water quality without breaking the bank.

Just remember it’s a filter-only system, so you'll need a separate softener if you have hard water

Whole house systems will be needed to support your home's entire water demand without reducing pressure. The majority of households need systems with the capacity to process 10-15 gallons each minute ( GPM ) to achieve adequate pressure to feed multiple fixtures.

Measure your present flow rate and choose a system in or above this capacity to avoid poor showers or slow-acting appliances.

Since whole house systems are required to solve all of your water quality issues at once, plan to tackle them in multiple stages. Sediment filters get rid of particulates, carbon filters eliminate chlorine and odor, and UV systems kill bacteria.

"Plan a multi-stage system to tackle your unique contaminants in sequence by size and by type," recommends Mike Stevens, water treatment engineer.

Whole house systems are installed by professionals and need space close by to service your main water line. Most units require 3-4 feet of space to change filters and service the system.

Consider the spot easy to access to change filters periodically, typically every 6-12 months depending upon the grade of your water and usage.

The large filters employed in whole house systems are costly to replace but are in service longer than smaller ones. Calculate the replacement costs of filters, energy utilized by UV systems or pumps, and potential professional service.

High-quality systems by reputable manufacturers may be costly but often prove to be less expensive in the long term by lasting longer and operating more effectively.

High-end whole house filters with proper sizing add very low drop pressure. 15-40 GPM systems with ratings maintain pressure well with simultaneous usage. Under-sized systems or dirty cartridges drop pressure significantly. Choose systems to match household flow to provide comfortable pressure levels in the household.

Upfront costs are $500-3,000 plus $200-500 installation. Filter replacement annually is $100-300 depending on usage and water condition . Installation by professional is recommended to ensure correct measurement and connection to plumbing. Make it an investment saving plumbing and appliances and improving overall water condition.

Replace sediment filters every 3-6 months and carbon ones every 6-12 months depending on water condition and household usage. High capacity systems with larger cartridges have longer lifespans. Monitor pressure and taste change and schedule to replace on your calendar to achieve best operation and avoid system damage.

Course carbon filters remove chlorine, but to remove chloramine requires special catalytic carbon. Fluoride is removed by activated alumina or reverse osmosis but is often impractical to install on a whole house basis. Use whole-house chloramine filters in combination with RO systems to provide total treatment of municipal supplies causing special issues in drinking and household usage.

After testing complete house systems, we found dramatic differences in performance, maintenance requirements, and long-term value.

The very best systems are professionally installed, offering complete coverage. Consider the unique issues in your home with the water, the flow rate requirements, and the expense of replacing filters periodically.

While whole house filtration is a costly installation, it preserves your plumbing system, upgrades water throughout the house, and eliminates the need for multiple individual filters. We recommend investing in a professionally installed system for optimal performance and long-term savings.
