A countertop pitcher or an under-sink filter cleans your drinking water, but every other tap, shower and appliance still gets untreated water. A whole house water filter, also called a point-of-entry system, treats water where it enters your home, so you get less chlorine taste and odor in the shower, less sediment in your pipes and appliances, and cleaner water at every faucet. The best whole house water filter targets the problems in your specific water without cutting your water pressure.
We compared the most popular whole house systems on what they reduce, how they handle chloramine and well-water problems, flow rate, filter life, installation and long-term cost. Here are our picks for 2026.

- Capacity1,000,000 gallons or 10 years; sediment filter every 6-9 months
- Flow9 GPM service (CF1, 1-3 bathrooms)

Many cities now disinfect with chloramine, which ordinary carbon struggles to remove. SpringWell’s whole house filter uses KDF, catalytic carbon and sediment filtration, and SpringWell says it removes chlorine, chloramine, PFAS, PFOA and PFOS.
The CF1 is rated at 9 GPM for homes with one to three bathrooms, with bigger CF4 and CF+ sizes. The media lasts 1,000,000 gallons or 10 years, and you change the sediment filter every six to nine months. It has a lifetime warranty, but it costs a lot up front and needs proper installation.
What we like
- Catalytic carbon handles chloramine
- Lifetime warranty
- Long-lasting media
- Sizes for 1 to 6+ bathrooms
Watch out for
- Expensive up front
- Large, heavy tank
- Professional install recommended
Best for: Homes where the water utility uses chloramine.
Skip it if: You only want a low-cost sediment filter.

iSpring WGB32B-PB 3-Stage Whole House Filter
- ReducesSediment, chlorine taste and odor, and lead

- CapacitySediment and carbon about 100,000 gallons; lead stage 150,000 gallons
- FlowUp to 15 GPM
- InstallDIY possible for handy owners
The iSpring WGB32B-PB uses three 20-inch big blue housings: a 5-micron sediment filter, a coconut shell carbon block and a lead-reducing cartridge. The plain WGB32B skips the lead stage, so pick the PB version if lead is a concern.
iSpring rates the sediment and carbon filters for 100,000 gallons, about a year for a family of four, and the lead stage for 150,000 gallons. Flow is up to 15 GPM, and it is designed for DIY installation. It costs $560.99 at iSpring, less than tank systems, but cartridges need regular changes.
What we like
- Lower up-front cost than tank systems
- Three stages including lead reduction
- Standard, easy-to-find cartridges
- DIY-friendly
Watch out for
- Regular cartridge changes
- Pressure can drop as filters clog

SpringWell WS1 Well Water System
- ReducesIron up to 7 ppm, hydrogen sulfide up to 8 ppm, manganese up to 1 ppm
- MethodChemical-free air injection oxidation with nightly backwash
- Flow12 GPM service (WS1, 1-4 bathrooms); up to 20 GPM
- ControlsBluetooth control; 10+ year media life
- WarrantyLifetime warranty, 6-month money-back guarantee
Well water often has problems that carbon filters cannot fix: rusty orange stains from iron, black stains from manganese and a rotten-egg smell from hydrogen sulfide. The SpringWell WS1 uses chemical-free air injection to oxidize these so the media can trap them.
A scheduled backwash flushes the trapped contaminants down a drain each night. SpringWell rates it for up to 7 ppm iron, 8 ppm hydrogen sulfide and 1 ppm manganese. It does not soften water or remove bacteria, so pair it with a softener or UV system if testing shows you need them.
What we like
- Tackles iron, manganese and sulfur smell
- Self-cleaning backwash
- No chemicals needed
- Bluetooth control
Watch out for
- Expensive
- Needs a drain for backwashing
- Does not treat bacteria or hardness
Best for: Private wells with staining or a sulfur smell.
Skip it if: You are on city water.

How to choose a whole house water filter
1. Test your water first
City water customers can read their utility’s yearly water quality report, then confirm with a home test kit or certified lab. Well owners should test at least once a year for bacteria, nitrates and other problems. Buy a system that targets what is actually in your water.
2. Match the filter to your source
City water usually needs carbon for chlorine or catalytic carbon for chloramine. Well water often needs sediment, iron and sulfur removal, and sometimes UV disinfection for bacteria.
3. Check the flow rate and pipe size
A whole house filter must keep up when several taps run at once. Look for a flow rate that matches your household, often 10 gallons per minute or more for a family home, and fittings that match your main line.
4. Count the long-term costs
Cheaper cartridge systems need frequent changes, while tank systems cost more up front but last for years. Compare the cost over five to ten years.
5. Look for independent certification
Certification to NSF/ANSI standards, such as Standard 42 for chlorine taste and odor, shows a product has been independently tested for its claims.
Whole house vs. drinking water filters
A whole house system improves water for bathing, laundry and appliances, but it is not always the best choice for drinking water. Lead, for example, often comes from older service lines and fixtures inside the home, after the water has passed the main filter. Many families pair a whole house filter with a drinking water filter at the kitchen sink.
- For drinking water, an under-sink or countertop filter certified to NSF/ANSI 53 or 58 can target lead and other health-related contaminants.
- For hard water, you need a water softener or scale conditioner, not a standard filter.
- For bacteria in well water, add a UV disinfection system after the filter.
- Keep any bypass valve accessible so you can change filters without shutting off water to the whole house for long.
Frequently asked questions
Is a whole house water filter worth it?
It can be if you dislike the chlorine smell in your shower, have sediment or well-water problems, or want to protect appliances. If you only care about drinking water, an under-sink filter costs much less.
Will a whole house filter lower my water pressure?
A properly sized system should cause little pressure drop. Pressure can fall as cartridges clog, which is a sign they need replacing.
Can I install a whole house water filter myself?
Simple cartridge systems can be DIY projects for handy owners. Large tank and well-water systems are usually best installed by a licensed plumber, and some areas require one.
Does a whole house filter soften water?
No. Standard filters do not remove the calcium and magnesium that cause hard water. You need a water softener or a salt-free conditioner for that.
How often do whole house filters need changing?
Cartridge systems often need new filters every 3 to 12 months. Large tank systems can last 5 to 10 years, with a small pre-filter changed every few months.
Does a whole house filter remove lead?
Some cartridge systems include a lead-reduction stage, but lead often enters from pipes inside the home. Use a certified drinking water filter at the tap if lead is a concern.
The bottom line
For most homes on city water, the Aquasana Rhino is the best whole house water filter, with a long-lasting tank and strong chlorine reduction. Choose the SpringWell CF1 for chloramine, the iSpring WGB32B-PB for a budget DIY system, or the SpringWell WS1 for well water with iron or sulfur.
