What is a Whole House Water Filter?
A whole house water filter is simply a series of filters that are installed on the main water line into your house.
These whole house filters can range in size, type, and technology depending on the unique contamination in your water.
By centralizing your water filtration and purification at the source, contaminants are filtered out before they can reach any point of use, such as your shower, sinks, washing machine, dishwasher, and hot water heater.
It doesn’t matter whether you have city water or well water, you could have damaging materials such as sediment, rust, silt, or lime/scale building minerals flowing through the pipes.
Most Americans have hard water with lime/scale that will damage pipes and appliances over time.
Even worse, your water may have contaminants and toxins such as lead, VOCs, pesticides, pharmaceuticals, nitrates and nitrites, chlorine, and microorganisms that can poison plants, pets, and people.
Only a test of your tap water will prove exactly what contaminants you should target. Even without a detailed water test, any of the issues above could be improved with one of the whole home water filtration systems recommended on this page.
We suggest some good water tests below.
Types of Whole House Water Filters
There are a few major types of whole house water filtration systems. Each type has pros and cons to consider and different applications depending on your water and the impurities you want to remove.
There is no single perfect whole house filter for everyone but there will be an appropriate water filtration system for your home based on your tap water and the issues it shows in tests.
Whole House Water Filter
A standard whole house water filtration system is often the right choice when you want to filter all of the water in your house.
With multiple stages, a whole home water filter system will first remove sediment, sand, silt, and clay with a sediment pre-filter.
Next, it will remove the most common water contaminants like heavy metals and organic contaminants including chlorine, chloramine, VOCs, pesticides and herbicides with a series of carbon filters, and other technologies described below.
Often, a third filter will provide a final cleaning or a targeted removal of something specific, like lead, fluoride, or microorganisms from your drinking water.
Then the filtered water will move on to all of the points of use in your whole house.
These whole house water filtration systems are the most common way to filter water since they are effective, reasonably priced, and often don’t require much maintenance.
We review and describe some top whole home water filters on this page.
A water softener (sometimes called a water conditioner), is a sub-type of whole-house water filter that works specifically to remove minerals such as calcium and magnesium from your water supply.
These minerals are collectively called “hardness” and they bind together and create scale – a whitish buildup on faucets and inside of pipes and appliances. Scale will decrease your water pressure, lower the water flow rate, and damage appliances.
Hard water affects more than 85% of homes in the United States.
While water softeners are great whole house system for removing the minerals that cause hard water and scale, they generally do not remove anything else. Water softeners are often installed beside a standard whole home water filter (like those found on this page) that will filter out other contaminants.
Be sure to check out our reviews of the top water softeners for more information about hard water.
Whole House Reverse Osmosis
If you want to know which whole home water filter removes the most contaminants everywhere in your whole house, there is no better way than with a whole house reverse osmosis water filtration system.
A reverse osmosis water filter (RO system) will remove more contaminants (up to 99%) than any other method and will ensure that every sink, shower, and appliance in your house gets the cleanest, pure whole house water.
Compared to the water filtering systems on this page, RO systems are more expensive to purchase and maintain.
Water Filtration Systems
Your city water supply is filtered and cleaned before it reached your home, but if you follow the news, you know there is no guarantee that municipal water is fully safe anymore. Many of the most dangerous chemicals are not filtered out of all tap water.
In many cases, tap water requires additional filtering since municipalities use different (but similar) methods to clean and disinfect the water that leaves behind chemicals, such as chlorine.
The damaging effects of chlorine and industrial runoff into public water sources are the most important contaminants to filter out before they are consumed in the kitchen or inhaled in shower steam.
Each of the filtration systems below represent a trusted brand of whole house water filters and each can be customized on the manufacturer website to work with the size of your home and the unique contaminants in your water.
See our comparison table of whole house water filters at the top of the page.
SpringWell Whole House Water Filter System
The SpringWell home water filtration system is the perfect solution for whole house filtration of municipal water with its four stages.
The four stages of water filtration include:
- Stage 1: sand, silt, clay, and other sediment are filtered through a 5 micron sediment pre-filter

Common Contaminants Removed by Whole House Filters
Here are some of the most common contaminants found in the U.S. drinking water supply that could and should be removed with a water filtration system:
Sediment is any suspended debris in water such as sand, silt, and clay. This is more of a problem in well water when it is pumped up from the ground.
A whole house sediment filter will remove these larger particles before the water moves on to other filters. This can be beneficial with any water source since sediment will shorten the filter life of the more precise filters in a system and decrease the flow rate in many of the water use points in your home.
Turbidity is the cloudiness in water caused by a large number of small particles that are not visible to the naked eye individually that will either settle out slowly or not at all. These particles can be made up of many different things, depending on the source of the water.
A whole-house turbidity filter will remove these fine particles and improve your water pressure and flow rate as well as extend the filter life of other stages.
Brown, red, or yellow colored water can be a sign of rust.
This is most often caused by iron and manganese in the water supply. Rusty water can also have an unpleasant smell. Your water source can be the culprit or if you only notice it with hot water, your water heater tank could be rusty inside.
Rust is a more common problem in well water and a whole home iron filter can be added to most whole house filters.
In water, sulfur will smell like rotten eggs as hydrogen sulfide gas escapes into the air. Sulfur is most often caused by bacteria in water and too much can lead to diarrhea or dehydration. Your own hot water system could contain breeding bacteria and any signs of sulfur taste or smell should be investigated.
A whole-house iron filter will remove sulfur from the incoming water source but will not help if there is bacteria in your hot water system. A reverse osmosis filter installed at the point of use (such as the kitchen sink) will remove sulfur from any source, including your hot water heater.
Sulfur is another problem that is more common in well water.
Like rust, iron in water leaves reddish stains and can lead to problems.
Iron in water often carries iron-feeding bacteria. Too much iron can lead to liver, heart, and pancreatic damage, as well as diabetes. Signs of excessive iron digestion include stomach problems, nausea, vomiting, fatigue, weight loss, and joint pain.
Excessive iron will also damage appliances and decrease the filter life of other stages in your filtration system.
A whole house iron filter is often an add-on for standard filtration system but may be included as a stage in some water softeners.
Chlorine and Chloramine
Chlorination is the process of adding chlorine or chloramine to drinking water to disinfect it and kill germs. This is one of the most common methods of “cleaning” municipal water supplies.
Chlorine and chloramine are toxic to fish, other aquatic animals, reptiles, and amphibians.
High levels of chlorine can leave a bleach-like taste in food cooked in water. When you bathe, chlorine dries out skin and hair. It can cause rashes (especially if you also have hard water) and inhaling it through shower steam can be harmful.
The carbon filter stages included in every multi stage whole house water filter will help remove chlorine, improve the water quality, and provide peace of mind.
Fluoride is a natural substance that is known reduce tooth decay. Municipal water authorities often add fluoride to the water supply with the goal of providing dental benefits to those that drink it.
However, there are many concerns about fluoride’s effect on general health when consumed in high amounts. High levels of fluoride in children can lead to several known issues and in adults, it can lead to brittle bones, thyroid and neurological problems.
A whole house water filter rated for fluoride or a reverse osmosis system will remove fluoride from your water.
Microorganisms, bacteria, giardia, viruses, cysts
Most common in well water and contaminated internal hot water systems, any form of microorganisms in drinking water can lead to health problems.
An add-on UV light (ultraviolet light) filter added to a water filtration system will kill microorganisms as they pass through in the water.
UV filtration is usually not necessary with municipal water, but a water test will tell you for sure.
Whole House Filter Installation
When you decide it’s time to improve the quality of your water and protect your family from harmful contaminants, you have several choices:
- You can call a plumber and have them provide the system and install it. This requires the least effort but does not provide you with any choice about what hardware is installed, if the system is well-rated, or if you can manage it yourself.
- You could also go and pick out a system at Home Depot, Lowes, or Costco and either have it installed or install it yourself. Again, you are very limited to the brands and features they offer and may not get the most effective options or a system that other customers are happy with.
- The ideal option is to use the information on this page and the knowledge you gain to pick the system from those we have already researched and recommend here. Why? Read on…
By picking something yourself that is popular, well-rated, and already researched and recommended, you can be sure you are selecting an option you can count on.
As a bonus, you are often getting a better system at a better price since there is much more competition online.
Once you have selected a great system from the options here and placed an order, you still have to install it. You can either hire a plumber and have them set it up or if you are comfortable with some simple plumbing, most of these systems can be installed by someone with DIY skills.
Many of the systems recommended here even come with DIY installation instructions!
In any case, be sure to think about the size of your home and number of people that regularly live there.
Systems are sized to have a flow rate (in GPM or gallons per minute) to match the needs of your home. Be sure to round up a little bit so that you don’t experience a drop in flow rate or problems with water pressure when you have guests in your home.
How much does it cost to install a whole house water filtration system?
It really depends.
A simple 3 stage whole house filter will cost less than one thousand dollars.
As you increase the flow rate, complexity, or filter stages, the price will increase into the thousands of dollars. However, if the water quality in your home is toxic or dangerous, then you need to consider the total cost of the health consequences to your family.
Filter System Maintenance
Most whole home water filter systems, regardless of the type, have simple maintenance to follow mainly with filter changes.
Anything with a filter in a multi stage whole house water filtration system will need to be periodically cleaned or replaced. The manufacturer’s instructions will make recommendations about how often to check and which replacement filters you will need.
While it may seem like a waste of money to perform filter changes or add salt (to water softeners), remember that these consumables are critical to the proper functioning of water filtration systems.
If you refuse to put oil in your car, eventually it will stop working.
The same is true for whole home water filter systems… If you don’t keep an eye on the recommended filter life and neglect to install a replacement filter when needed, your whole home water filter will stop cleaning the water and your family will be back to drinking the unfiltered contaminants you set out to remove!
Without regular replacement filters, you could also experience a drop in water pressure, flow rate, or an increase in color and odors.
Pre and post filters require the most filter changes.
While the manufacturer’s recommendations for filter changes are a good baseline, their instructions for maintenance are based on averages and ideal conditions. If your water pressure, water temperature, or contaminant load are much different than the average levels, then your system may need maintenance earlier or later than the standard recommendations.
To be sure your system is working as advertised, water testing is the ideal way to check. Periodically test both the water entering and exiting the system to be sure the contaminants you care about are filtered down to a safe level. This can be done either with periodic lab testing or with more frequent tests at home, assuming a DIY test for each contaminant is available.
The pre-sediment filter, carbon block filter (and other carbon filters) are the stages that most often need filter replacement.
Do I even need a whole house water filter?
Wait… what if you got this far and realize you don’t need a whole house water filtration system?
Why would that happen?
Maybe the contaminant load in your water is higher than you like, but not concerning, so you don’t care about the laundry or shower water quality.
If you don’t have hard water, you don’t need a water softener.
What if you just want to have pure, clean water in the kitchen for drinking, cooking, or even the ice maker?
Then you should check out our reviews of the under sink reverse osmosis water filters. These systems are less expensive than whole house filters and provide the cleanest possible water, just where you use it the most.
Undersink reverse osmosis systems are the most common option but you can also get a countertop water filter that needs only minimal or even zero installation.
You can combine a specific whole home filter like a water softening system or an iron filter (if those are problems for you) with a reverse osmosis system just in the kitchen.
Together, they will provide peace of mind that you have great water quality at each point of use.
Water Filtration Terms and FAQ
What is GPD?
GPD stands for “gallons per day.” Whole home water filters are often rated based on how many gallons they can filter per day (or gallons per minute – “GPM”) in ideal conditions. While not perfect, it is a good way to compare the water flow rate of competing systems.
The “stages” of a water filtration system refer to the number of different filters water passes through before it is considered clean. No one filter type removes everything well, so a multi stage water filter works together to remove multiple contaminants.
A polypropylene sediment filter will remove large sediment and is an important part of any multi stage whole house water filter system. The sediment filter protects the rest of the system (and your home) from large particles and will help to extend the filter life of other stages.
Carbon filters, coconut carbon filters, or coconut shell carbon media are all names for carbon filters that are good at removing other larger contaminants like heavy metals.
Every one of our recommended whole house water systems are a multi stage water filter to ensure that the water quality is improved as much as possible.
What is TDS?
TDS stands for “total dissolved solids.” It is a measure of the combined total of organic and inorganic substances contained in water. This can include anything present other than the pure H20 (water) molecules and is usually made of minerals, salts, and organic matter.
The measured TDS number is a general indicator of water quality and you would expect to see a large decrease in TDS between unfiltered and filtered water.
What is hard water?
Hard water refers to water that has a high concentration of the minerals calcium and magnesium. These minerals are not dangerous to drink but they will build up over time in faucets, pipes, and appliances in the form of white “scale” deposits. Hard water will also prevent soap from foaming properly and will dry out skin and hair.
What is soft water?
Soft water is water that has low concentrations of minerals such as calcium and magnesium. While most water in the U.S. is hard, soft water is most often achieved by installing a water softener or water conditioner that neutralizes or removes these minerals.
NSF International Certification
NSF International provides NSF/ANSI certification for manufacturers that want to prove that their water filtration system complies with the technical requirements of the standard, usually for removal of specific contaminants.
For the whole home water filter manufacturer, this is a long and expensive process (which is why more countertop filter systems are not NSF certified). The system must be initially reviewed, tested to comply with the published standard, and approved. Then, there will be follow up inspections and testing in the future to ensure all compliance items are still met.
Water Quality Association (WQA) Certification
WQA (the Water Quality Association) provides certified listings that prove products have been tested and approved to comply with their stated claims.
Many whole home water filter systems will have this certification to prove that contaminants are removed as claimed by the manufacturer.
What is KDF Media?
Kinetic Degradation Fluxion (KDF or KDF Media) is a high-purity copper-zinc formulation that uses a basic chemical process known as redox (oxidation/reduction) to remove chlorine, lead, mercury, iron, and hydrogen sulfide from water. The process also has mild anti-bacterial, anti-algae, and anti-fungal effects and may help to reduce the accumulation of lime scale.
It is also used along with activated carbon to more effectively filter water.
KDF Media vs. Activated Carbon Filter
|Life||6+ Years||Only 6 to 12 months|
|Bacteria and Algae||Controls Both||Permits Growth|
