A whole house water filter for well water is ideal to clean all incoming water to your home. This so-called point-of-entry (POE) filtration gives you access to filtered water at every faucet, tap, shower… – you name it!
Among other benefits, a solid filter system improves water aesthetics, removes harmful contaminants, and maybe most importantly it traps sediment and other dirt which prevents your plumbing and water-using appliances from taking harm.
This leaves us with the question: Which whole house water filtration system for well water is best suited for your situation and water conditions? This is exactly what we’re going to discuss in the guide below. Ready? Let’s go!
SpringWell WS whole house well water filter system eliminates staining of your laundry as well as in toilets, showers, sinks. Plus, it neutralizes rotten egg smell and makes your water taste way better.
Air injection oxidation combined with greensand filter media remove a maximum combined of ferrous and ferric iron of up to 7 ppm, manganese up to 1 ppm, and hydrogen sulfide up to 8 ppm.
Greensand also helps with radium and arsenic.
Filter process is compatible with septic systems.
Add optional UV filter stage for treatment of microbiologically unsafe well water systems.
2 system sizes:
SpringWell Whole House WS1 provides 12 gpm water flow (1-4 bathrooms).
Larger filter version: 20 gallons of water per minute is enough to supply homes with 4+ bathrooms.
Process includes periodic backwashing of greensand to flush out all accumulated contaminants and daily air pocket reset. The electronic head unit manages both so you don’t have to worry about it.
Electronic head can be programmed at the system or remotely via mobile device app.
System is easy to install for do-it-yourselfers.
Installation kit can be purchased as optional add-on.
Detailed installation instructions and bypass valve are included.
In most cases, there is absolutely zero maintenance required. The filter media lasts for 18 to 25 years.
System is backed by 6-month money-back guarantee.
Manufacturer also provides lifetime warranty on valve, tank, media, and fittings.
2. The Runner-Up: US Water Systems Matrixx inFusion Iron and Sulfur Removal System
Alternatively to the SpringWell WS, we recommend the Matrixx inFusion iron and sulfur removal system by USWS.
Unlike the WS which uses air injection for pre-oxidation followed by greensand filtration, the Matrixx inFusion pairs hydrogen peroxide with catalytic activated carbon media. This powerful combination is designed for filtering very high levels of iron, manganese, and sulfur. What’s more, hydrogen peroxide injection is also highly effective against iron and sulfur bacteria!
USWS Matrixx inFusion Iron and Sulfur Removal System
The chemical pump injects hydrogen peroxide (H2O2) into the water stream for pre-oxidation. Any iron, manganese, and sulfur oxidize instantly and precipitate from the solution. When the water gets in contact with the catalytic activated carbon media, all oxidized contaminants get trapped.
Hydrogen peroxide is a very powerful oxidizer. Powerful enough to eliminate any iron and sulfur bacteria and other microorganisms.
The filtration process also neutralizes odors.
Compared to chlorination, there are no unwanted byproducts.
Sediment, silt, sand, and rust are removed likewise.
Your plumbing, fixtures, and appliances are protected from damage.
During backwash, accumulated contaminants are rinsed from the filter media.
Performed automatically every few days.
A Vortech plate in the bottom of the tank increases backwashing efficiency for up to 30% water savings. And it prevents media channeling prolonging the life of the carbon.
4 sizes to choose from:
10 gpm peak water flow rate for 1 to 2 baths.
15 gpm designed for 2-3.5 bathrooms.
20 gpm is ideal for 4-6 baths.
25 gpm for 7 baths or more.
Package includes everything you need: 15-gallon hydrogen peroxide tank, chemical injection pump, water meter, 5 gallons of NSF-approved H2O2 (OxiPro-7).
The chrome tank protector is easy to clean.
Installation is easy also thanks to detailed step by step instructions.
Programming can be done in less than 2 minutes via smartphone. Free app also tracks water usage.
No maintenance required.
You get a lifetime warranty on the media tank, 10 years on the head valve, 5 years on the chemical injection panel.
Expenses for hydrogen peroxide amount to $200-400 per year.
3. Best Rated Whole House Water Filter for Well Water with Chemicals: SpringWell Water CF
In our opinion, the best water filtration system for well water with chemicals in 2022 is the SpringWell Water CF. It was designed for removing chlorine and chloramine, and various chemicals such as disinfection byproducts, pesticides, herbicides, and VOCs. That’s why the system is very often used with city water. However, it is equally compatible with well water as long as there isn’t too much iron and manganese that could clog the catalytic carbon filter bed.
One use case: Filtering excess water disinfectants that result from shock chlorination. The system also improves drinking water aesthetics by a lot. Definitely 5 stars!
4. #1 Whole House Sediment Filter for Well Water: Crystal Quest
The Crystal Quest is another great setup only that this time the filter specializes on sediment removal. Of course, sediment can often be found in abundance in well water so designing a whole house well water filter for that purpose alone makes complete sense. 5 stars.
5. Our #1 Cartridge-Based Well Filter System: Home Master HMF3SdgFeC
For people on well water that prefer a system based on filter cartridges we recommend the Home Master HMF3SdgFeC. Specifically designed for chlorine-free water supplies with moderate iron levels, it provides an entire home with clean, filtered well water. 4.5 stars!
Best well water filtration system of its kind. Users are highly satisfied with the results they get: No more iron staining, clean taste, and refreshing smell right after installation.
First filter stage uses a high quality multi-gradient density sediment filter (25 – 10 – 5 – 1 micron nominal) to remove sand, rust and other particles from your private well water. Also takes out harmful cyst and bacteria – think E. Coli.
According to manufacturer, multi-gradient density filters have three times the dirt holding capacity of similar sized sediment filters.
Next comes an iron filter cartridge. It can filter up to 3 parts per million ferric and ferrous iron from well water, and also reduces hydrogen sulfide and manganese.
Sulfur and manganese reduce the service life of the filter at 2-6 times the rate of iron.
Granular activated carbon filter (20 microns nominal) gives the water a final polish. It eliminates harmful chemicals including herbicides, pesticides, chlorine, VOCs, and any remaining tastes and odors.
Up to 15 gpm clean water flow should be sufficient for homes with up to 4-5 bathrooms.
As with most whole house filter systems, the installation is relatively simple.
Maintenance requirements are conveniently low. Required filter replacement frequency depends on the condition of your well water and your daily water usage. Expect that you need to change filters twice per year.
Home Master offers to check your water report and give treatment recommendations for free. Overall customer support is great from knowledgeable staff members.
6. SoftPro Iron Master AIO Water Filtration System
Another solid well water filtration system for high levels of iron is the SoftPro Iron Master AIO by Quality Water Treatment. The whole house water filtration system can handle extreme levels of iron, manganese, and sulfur with ease. And the pricing is good, too!
7. iSpring WGB32B Big Blue 3-Stage Whole House Water Filtration Systems
The iSpring WGB32B 3-Stage comes in a few different versions designed for different water contamination issues. For well water, we recommend either the iSpring WGB32BM for iron and manganese reduction, or the iSpring WGB32B-KS which removes a broad range of heavy metals commonly found in wells.
As a whole house well water filter system using filter cartridges the price tag of both iSpring units is low.
Both system versions use a sediment pre-filter rated at 5 microns to remove dirt, colors and cloudiness.
The following coconut shell carbon block filter is used to remove chlorine taste and odor, organic contaminants, and chemicals.
iSpring WGB32BM features iron and manganese filter. It can remove up to 3 ppm iron from well water and an additional 1 ppm manganese. Several other metals will be reduced, too.
iSpring WGB32B-KS uses a third filter stage (post-filter) that combines granular activated carbon with KDF media. It effectively removes lead, mercury, hydrogen sulfide, pesticides, herbicides, and more.
Max service flow rate is 15 gpm (1-4+ bathrooms).
20″ x 4.5″ Big Blue filters are standard sized. Their filtration capacities range from 50,000 gallons of filtered water to 150,000. Thus, there isn’t too much maintenance required.
Replacement filter costs start to add up over time. Also, due to issues with outgoing water pressure some reviewers reportedly had to change their filters much more frequently than advertised adding to the expenses.
8. Express Water 3 Stage Whole House Water Filtration System
The Express Water 3-stage whole house water filter is a universal talent. Tested to remove 80+ contaminants from well water it is one of the most sought after water filters on Amazon – also because the initial price tag is much smaller than the competition’s.
Provides great-tasting and clean drinking water at every tap in your home.
Clean shower water promotes healthy hair and skin. Indoor air quality will improve, too.
A 5-micron sediment pre-filter removes larger particulates. Protects the rest of the water filtration system from clogging.
High-grade catalytic granular coconut shell carbon provides for the highest filtration capacity and effectiveness, meaning broader contaminant removal.
Pelican Water guarantees the removal of chlorine + chloramine below the minimum detection level for 1.3 million gallons or 5 years.
Chlorine taste and odor reduction is NSF/ANSI certified (Standard 42).
Bacteriostatic KDF-55, a mixture of copper and zinc, stops microorganisms from accumulating inside the tank and further reduces chlorine as well as lead, nickel, mercury, chromium, and other dissolved heavy metals.
All in all, chemical and non-chemical well water contaminants – some with potential health effects – are removed by the whole house filter. The end result is much cleaner and much healthier (drinking) water.
12 gpm flow rate is enough for large homes with 4 to 6 bathrooms.
Smaller system version:
650,000 gallons or 5 years filtration capacity at 8 gpm (1-3 bathrooms)
Large media tank is wrapped in stainless steel for longevity.
Except for priming the carbon filter bed, the system is no more difficult to install than any of the filters reviewed above.
Comes pre-assembled and pre-loaded.
Built-in bypass valve.
Maintaining the system is easy. All you need to do is replace the pre-filter on time. Costs are negligible.
90-day money-back guarantee.
Limited lifetime warranty for peace of mind.
Media priming seems more complicated that it needs to be.
A handful of people complained about a leaking system.
10. Affordable Whole House Water Filter System: Aqua-Pure AP903
In the last of our whole house well water filtration system reviews we’ll take a look at the Aqua-Pure AP903 by 3M. It’s not our favorite filter but certainly a solid alternative for people on a small budget.
We see the real value of the single-stage filtration system in improving the aesthetics of city water, but it works for wells, too, provided that it’s fairly clean already.
5-micron nominal carbon block filtration combined with non-woven pleat media filter sediments, chlorine, and chemicals. On the one hand, this will improve the taste of your drinking water. On the other hand, it helps home appliances to last longer.
High flow rate of up to 20 gpm is ideal for large homes.
The 304 stainless steel head is corrosion resistant and thus provides for a long service life without affecting water taste.
Easy installation due to slim design. The 3M Aqua-Pure fits in any corner.
Filter replacement is super easy. All it takes is a quarter turn to remove the old filter cartridge and another quarter turn to install the new – no tools required.
The head valve is warranted for 25 years.
Some people have to replace the filter cartridge more often than advertised. They don’t even come close to the 100,000 gallons of filtered water or 12 months as specified by 3M. Maybe that’s due to high total dissolved solids levels.
Of course, replacing the filter at such frequency doesn’t make much sense. Adding one or more pre-filter stages makes sense.

Buyer’s Guide – Considerations When Buying a Whole House Well Water Filtration System
Before you go shopping for a whole house water filter system, consider this:
Test Your Private Well Water Quality
Do you even need a whole house water filter? And if so, which type is best suited for your well supply? The short answers is: It depends on your water conditions. This is why you need to test your water quality carefully before you do anything else.
You should determine the exact contaminants present in your water and their concentrations. And it can make sense to measure water pH, hard water minerals, and overall TDS (total dissolved solids).
Armed with these parameters, you can measure the various whole house water filters on the market against your requirements and compare them to one another.
By the way, in our opinion the best way to test your well water quality is by sending a sample to an independent laboratory (to these guys for example). The professional staff can then do a thorough analysis and provide you with everything you need to know.
Of course, you could also do the testing yourself using a simple water test kit sold by hardware stores. The reason why we don’t recommend this approach is because the testing lacks accuracy. Also, you will only be able to test for a narrow range of common contaminants.
Whole House Filtration System Types
In a nutshell, most whole house water filter systems use some sort of carbon and maybe a sediment filter to remove the most common water contaminants. These include chlorine/chloramine and their disinfection byproducts, a handful of heavy metals, and chemicals like herbicides, pesticides, and industrial solvents. Catalytic and regular activated carbon is also great for improving the taste and smell of water.
That said, carbon and sediment filtration is a good start, but your well water might require a different kind of treatment.
If you are dealing with the different forms of iron, for example, you need a specialized iron filter. Usually, this type of well filter is also effective against manganese and sulfur. All three contaminants are commonly found in wells.eed to test your well water q
At higher levels, pre-oxidation of the iron may be required. This is often achieved through air injection. Other methods include ozonation and chlorine injection. The pre-oxidation is then followed by specialized filtration media such as greensand or Katalox.
KDF media (copper-zinc alloy) can be used to control bacteria, viruses, and other microorganisms. Above that, it helps the chlorine reduction and also filters heavy metal content.
It’s also quite possible that all you need is a sediment filter to trap suspended solids. Sediment filters are either cartridge-based or use a large media tank.
Last but not least: UV filter stages. A UV filter is used to kill the various kinds of pathogens that can live in well water. Most common are bacteria, fungi, viruses, and cyst. UV light messes with their DNA so they cannot reproduce.
We can also distinguish between cartridge-based whole house water filters and those using a large tank filled with granular filter media. The main difference is that whole house cartridge water filters cost less upfront, but expenses for replacement filters can start to add up quickly. Whole house filters that feature a large media tank require a higher initial investment, but less attention and money once installed.
Water Flow Rates
The United States Environmental Protection Agency estimates that “the average American family uses more than 300 gallons (…) per day at home. Roughly 70 percent of this use occurs indoors”. (Source)
70% of 300 gallons equals 210 water gallons that the average household uses in a single day. This incredibly huge amount of water can further be broken down into:
24% (50.4 gallons) for toilet flushing
20% (42 gallons) for showering
19% (39.9 gallons) for taps and faucets
17% (35.7 gallons) washing clothes
12% (25.2 gallons) wasted through leaking
8% (16.8 gallons) for other uses
First of all, this is a lot of water. But let’s also think about how much water you use when, because this becomes important for sizing a well water filter. After all, you don’t want to end up with a system that’s too small causing an occasional drop in water pressure and flow when you open multiple water outlets at the same time.
Quite the contrary: A whole home water filter needs to be able to process enough filtered even at times of peak use. One scenario that we like to use is on a regular morning when your family is getting ready for the day. Showers and faucets are running, someone flushes the toilet, and you start the washer.
Bottom line: Make sure to estimate your water consumption in gallons per minute at times of peak consumption.
As a family of four, we recommend to go with at least 8 (10) gpm. Large families living in a large home can easily use 15 gpm.
Sediment filters and some carbon filters are rated by the size of the smallest particles they can remove. For carbon filters, this rating is nominal and therefore less reliable than absolute ratings.
For example: A sediment filter rated at 10 microns means it can remove all suspended solids sized 10 microns or larger. Other common micron ratings are 50, 25, 5 and 1. Ultrafiltration cartridges can even reduce contaminants of submicron size.
Simply put, smaller micron rating means more contaminants can be removed. But there is a dilemma: Very fine filters tend to reduce water pressure and clog up quickly. Therefore, a good balance between usability and filtration effectiveness is key.
Filter Service Life
Depending on the type, whole house filter cartridges can last between 2 or 3 months and up to 1 year. The filter life of large media beds can often reach more than a decade.
A long filter life has the obvious advantage that maintenance is required less often which also keeps cost at a minimum.
Well or city water – a whole house filter needs to be installed at the main water line of your home. Most systems are larger than you’d think so make sure that you have sufficient space at the installation sight.
As mentioned before, POE filter systems using cartridges are more affordable at purchase but the cost for new replacement filters adds up quickly. For POE systems using a large media bed it’s the exact opposite.
Another cost factor is installation. Expect at least a few hundred dollars extra in fees, unless you are a DIYer and can connect the system yourself.
What Is a Whole House Water Filter for Well Water?
A whole house well water filter system filters the water from your private well before its distribution throughout your home.
Because well water is raw water and, unlike tap water, doesn’t receive any pre-treatment, a whole house water filtration system is a must for well owners. This is especially the case if you are planning on drinking the water.
Most importantly, a sophisticated filtration system will protect your health against harmful chemicals, pathogens, and metals. Another reason to add a whole house water filter for well water to your home is that filtered, clean water tastes and smells much better. Removing sediments also helps your plumbing system and water-using home appliances.
Since we are talking about POE filters, installation at the main water line is required. This can be done by yourself or a professional installer.
Maintaining most whole house filtration systems is simple. You just need to remember to replace filters in due time.
Why Do I Need a Well Water Filter?
All municipal water goes through various stages of treatment to guarantee consumer protection. This does in no way apply to most private wells. This is why well water may contain a whole plethora of harmful contaminants and those that affect water smell and taste. It is your responsibility as a well owner to make sure that the water you and your family use on a daily basis is clean and healthy.
On top of that, clean well water does not damage appliances like water heaters and provides for an extended service life.
Bacteria, viruses, and other pathogens in well water usually originate from animal waste (farming) or human sewage (i.e. leaking waste storage tank or septic field) and are therefore man-made. The pathogens trickle into the earth entering our groundwater or are washed into nearby water sources as part of rainwater run-off or snow melt. When ingested, they can cause diarrhea which is rather harmless. But also more serious diseases can be transmitted this way.
The mining and oil industry are the two main contributors to heavy metal contamination of our water sources. Another common contamination source for heavy metals in wells can be a home’s plumbing system. And even natural deposits can be the root of the problem. Metals most commonly found in well water are iron, manganese, and arsenic. Chromium 6 and lead can be problematic, too – and pose a serious health threat.
Agriculture in particular is the reason why more and more chemicals are ending up in our wells. Health consequences are manifold: Liver damage, impairment of the male and female reproductive system, cancer.
How Whole House Water Filtration Systems for Well Water Work + Contaminant Removal
As the name suggests, this type of water filter processes all the incoming water in your home. Opposed to point-of-use filtration, point-of-entry filtration gives you access to filtered water at every single outlet: Bathroom taps, showers, kitchen faucet – you name it.
The exact process each filter uses can be different from model to model.
Most start with a simple sediment pre-filter. This is to trap large impurities that may otherwise clog the following filter stages. Some whole house water filter systems even focus on sediment filtration alone.
The main treatment process might combine two types of filter media: Catalytic activated carbon and KDF. The mixture is used to removal chlorine, heavy metals, and various organic chemicals from water, among other things. Carbon is also perfectly suited for improving water aesthetics.
Or a filter may use pre-oxidation followed by greensand for the removal of iron, sulfur, and manganese.
Activated alumina and bone char can be used to reduce naturally occurring fluoride.
Installing a UV filter is important if your water testing showed any kind of viruses, bacteria and the like.
How to Install a Whole House Well Water Filtration System
This section explains how to hook up a whole house filter. However, please consider these general guidelines. The exact procedure to install your filter system may differ.
Check if you need to prime any media before the actual installation process can start. The priming often takes more than 24 hours and needs to be taken care of in advance. Refer to your user manual for further information.
Start the installation process by shutting off the water supply.
The next step is to drain any remaining water. Just open the nearest outlets.
Once all water is drained it’s time to remove a piece from the main water line. Use a pipe cutter or hacksaw for this.
Consider installing additional shut-off and bypass valves on either side of the filter system. They can come in handy when you need to service the unit.
Put the whole house filter system into place. Level ground is mandatory. Also make sure that inlet and outlet port face in the right direction.
Establish a connection between the incoming end of the line and the filter’s inlet port. Do the same for the outgoing line and outlet port. We recommend shark-bite fittings and flex hoses. Also remember to seal any threaded ends with Teflon tape.
Almost done! Slowly open the main water supply and allow flow into the filter system while checking for leaks.
All good? Let your new water filter flush for a couple of minutes. This also removes any remaining air and installation debris.
Is installing a whole house water filtration system yourself a good idea?
If this is not your first DIY project we definitely think you should give it a try. DIY-installation saves you a lot of money that you would otherwise have to spend on a plumber. Only if installation by an amateur voids the product warranty we would recommend hiring a professional installer right away.
Where to Install
With well water systems, the best position to install a whole house filter is after the pressure tank but before the water softener in case there is one. This provides for a sufficient flow rate for backwashing while protecting any water softening equipment against sediments etc.
System Maintenance OR How to Change a Whole House Water Filter for Well Water
Most whole house water filtration systems are either entirely maintenance-free or all they need is a new sediment pre-filter every once in a while – easy!
The only thing to remember is that you replace each filter stage as instructed by the manufacturer. This provides for the highest filtration effectiveness and prevents germs from accumulating and contaminating your water.
Here is how to change a whole house water filter:
Again, the first step is to close the water supply.
Drain water that remains in the water line.
Filter housings are best opened using a filter wrench. For more stubborn housings you might need a filter strap.
Once removed, take the old filter out of its housing.
Insert a new filter cartridge.
Before screwing the filter housing back on, check the condition of any O-rings. Lubrication or replacement may be required.
Turn the water supply back on.
Check for leaks.
Flushing of the new filter cartridge may be needed.
Benefits and Drawbacks of Using a Well Water Filter System
What are the pros and cons of using a water filter system for your well?
First and foremost, a whole house filter protects your health. If you’ve done thorough testing and chosen a filter model accordingly, all or at least the majority of contaminants will be removed from your well water during filtration.
You will have clean water in your entire home.
Clean water is easy on your water-using appliances and your plumbing system in general. Chances are that you will benefit from reduced maintenance/repair and a longer service life further down the road.
Thoroughly filtered drinking water tastes and smells great.
Most well water filtration systems can be DIY-installed in order to save money.
Maintaining a whole house water filter system is child’s play.
Price tags of whole house filter aren’t small. System installation and maintenance are cost factors you also need to take into account.
There is not a single water filter that removes every last impurity. Thus, it often needs a combination of two or more whole house water filter systems to get hold of all the contaminants – including iron, manganese and other heavy metals, chlorine, VOCs… – that are present in your water source. It’s the best way to make almost any water safe to drink.
Frequently Asked Questions (FAQ)
Does a whole house well filter remove hard water minerals?
Most of them don’t. However, water softeners were invented for that exact purpose: Reduce water hardness producing soft water. And if you don’t like the idea of added sodium in your water, you can buy a saltless water softener.
Should you filter private well water?
You absolutely should filter your private well water if it’s dirty, which applies to most wells in the U.S. Pro tip: Test your water.
Do I need a well purification system if I have a salt-free water softener?
You might need a water purification system. A saltless water softener like all water softeners in general reduces hard water scaling, but nothing else. Do a water test to find out whether or not you need a water filter.
How much does a well water filtration system cost?
The costs range from less than $100 USD for a simple sediment filter to well above $3,000 for a large, specialized iron filter.
