10 Best Whole House Water Filters Reviewed
After investing our time researching and reviewing several whole house water filters, we identified the 10 best options for different purposes.
We’ve invested the time so you don’t have to:
In our opinion, the Aquasana EQ-1000 Whole House Water Filter is overall the best whole house water filter available. It delivers a great combination of NSF certified filtration technology capable of removing the most common contaminants of your water, with amazing longevity of 10 years, a 10-year warranty, a decent flow rate of 7 GPM, and a possibility of add-ons to deal with other types of contaminants that might exist in your water source.
The Aquasana EQ-1000 Whole House Water Filter is an NSF certified filter capable of remove 97% of chlorine, but also reducing other harmful contaminants like VOCs, pesticides, herbicides, heavy metals, etc, to produce clean water for your home, and you will notice not only tastier water but also a better feeling on your skin and hair while showering and/or bathing.
It has a unique upflow dual tank design that increases the time that the water is in contact with the media filter which increases the number of contaminants removed, and has bacteriostatic media to prevent bacteria and algae from growing inside the filtration system.
This special design also makes tank replacement much easier than other systems. But you won’t need to change the filters often, because the 1.000.000 gallons capacity is enough to deliver clean and fresh water for 10 years.
The Aquasana EQ-1000 Whole House Water Filter comes with a 10-year warranty, and a 90-days money back guarantee, which gives you the peace of mind to try it first and decide if it is a good solution for you.
In our opinion, one of the key differentiator factors of this whole house water system is the ability to add additional filters or have a different variation of it to suit your needs. If you have hard water, you can buy a whole house water filter and natural salt-free softener combo, having the best of both worlds with clean and soft water. And if instead of hard water, you have a problem with bacteria and/or viruses in your water source, you can add a UV filter to deal with those harmful contaminants.
The only point that we didn’t like much is the water flow of 7 GPM. While it is a decent water flow, it might not be enough if you have a large home with multiple people using water at the same time.
- NSF certification
- Removes 97% of chlorine
- Reduces scale buildup
- Long filter longevity
- 90-day money back guarantee
- 10 year warranty

Buying Guide for Whole House Water Filter
Buying a Whole House Water Filter is not easy, as different households have different needs and you should buy the one that suits your family, to ensure they have access to clean and healthy water.
That is why we present a curated selection of the best whole house water filters for different situations, and we also created a comprehensive buying guide for whole house water filters so that you can understand the most important factors and be able to make the best purchase decision.
What to Consider When Choosing the Best Whole House Water Filter
When researching for a Whole House water filter to buy, these are the key features that you should consider:
Contaminants to Remove
It is important to start by knowing which contaminants you need to deal with at your home. You can do this, by checking the CCR of your water provider or by checking the water of your home by yourself, using a water test kit.
This is relevant information to decide the type of whole house water filter that best suits your situation, as you probably won’t need the more expensive one in the market.
Purchasing a whole house water filter is not cheap, and you should consider the cost associated with it before you buy it, to ensure you make the right choice.
There are different whole house water filters in the market, and the price can vary from a few hundred dollars to more than one thousand dollars, depending on the brand, certifications, type, contaminants it removes, capacity, etc.
And you may also need a plumber to install the whole house water filter, so consider a few hundred dollars more to your budget.
Apart from these initial costs, you will need to change your cartridge filter with some frequency, so it is important to understand this recurring cost also.
You should ask yourself how much water does your family consumes per day, to have an idea of the capacity of the water filter that you are going to need.
If you have a big family or if your family consumes lots of water, you might need a whole house water filter with a high capacity, to avoid having to replace filters too often.
Water flow, or flow rate, is measured by the amount of water in gallons per minute, or GPM. Because a whole water filter is going to filter water for your entire household, it is important to understand how much water you are going to need, to avoid water interruptions or low water flow.
If you need large amounts of water at the same time, is better to go with a water filter with a higher water flow, if your household is small you should be ok with a water filter with a lower water flow.
You will need to replace the filter cartridge of your whole water filter from time to time, and that activity will be determined by the longevity of the filter.
You should go for a combination of good longevity and decent price, to not have to change the filter quite often and minimize the recurring cost of changing the filter.
Both NSF or WQA are independent third-party accredited institutions that certify water filters, which gives the consumer the trust that those products can remove certain harmful contaminants.
Some brands will claim they are tested according to NSF standards, but we can only be sure the products were tested by a third-party accredited institution for the ones with certification.
Some of the most common NSF certifications for water filters are:
- NSF 42: for aesthetic effects, this certifies systems designed to reduce non-health-related contaminants, such as chlorine, chloramine, taste and odor, iron, manganese, particulate, and total dissolved solids (TDS).
- NSF 44: for cation exchange water softeners, certifies this type of system to reduce hardness caused by calcium and magnesium ions, replacing them with sodium or potassium ions.
- NSF 53: for health effects, certifies systems designed to reduce specific health-related contaminants, such as lead, Cryptosporidium, VOCs, and chromium.
- NSF 55: for UV systems, certifies this type of system to inactivate or kill bacteria, viruses, and cysts (Class A) or to reduce the amount of non-health-related bacteria (Class B).
- NSF 58: for Reverse Osmosis (RO) systems, this certifies RO systems designed to reduce TDS and additional contaminants, and ensures the safety of the materials in contact with drinking water, structural integrity, and efficiency rating.
- NSF 401: for emerging compounds/incidental contaminants, this certifies systems designed to remove up to 15 individual contaminants which have been identified in published studies as occurring in drinking water, such as prescription drugs, over-the-counter medications, herbicides, pesticides, and chemical compounds.
System Physical Size & Space Available
Whole house water filters are not small, so you need to make sure you have enough space to install your new system in a place where you can connect it to your main water line.
And take into consideration that you need to be able to access it in the future to change filters and/or perform some maintenance activities.
What is a Whole House Water Filter?
A Whole House Water Filter is a point-of-entry (POE) system, which means that it is connected to the main water line to filter all the water at the point of entry, before it enters the household.
This way, all the water in the house is filtered and clean, both cold and hot water. You will only have filtered water in your house, so in your faucets, showers, appliances, toilets, etc., reducing the contaminants around and improving the quality of your life.
How Does a Whole House Water Filter Work?
Typically a Whole House Water Filter will have at least 3 filtering stages, but there other optional filtering stages that some filters will have:
- Pre-sediment filter: This filtering stage removes large particles like dirt, dust, impurities, and sand, which will not only remove contaminants from the water, but will also help prevent these particles from going through the filters on the other stages and reduce their expected life.
- Activated carbon filter: In this stage the water passes through an activated carbon block, removing several contaminants that become trapped in its pores, such as chlorine, chloramine, volatile organic compounds (VOCs), bad taste and odor, pesticides, etc
- Copper-zinc filter: This combined filter removes most of the remaining contaminants at this stage, like lead, mercury, chemicals, bacteria, microorganisms, and other metals.
- Post-filter (common, but optional): Not all whole house filters will have this final stage, in which the filtered water goes through a final polish before it enters the house’s main water line. If there are still some small contaminants in the water (the larger ones were removed in previous stages) this stage will filter them out, using filters with holes around 1 micron, and some whole house filters can have post-filters with holes as small as 0.35 microns.
- Water softener (optional): Some whole house filters have a water softener stage in which the water goes through an ion-exchange filter that replaces magnesium and calcium ions with sodium ions, making the water softer, but also a bit saltier. This stage can be particularly important if you have a hard water problem in your household.
- UV filter (optional): Like the water softener stage, some whole house filters have a UV filter stage that is used to kill remaining contaminants like microorganisms, viruses, or bacteria. This stage can be particularly important if your water has a high level of bacterial contamination.
- Remineralization filter (optional): Another additional stage that some whole house filters offer is remineralization, in which some healthy minerals, like calcium and magnesium, that might have been removed in the early filtering stages are added back to the filtered water at the end of the process.
The Different Types of Whole House Water Filters
There are different types of whole house water filters, and some of them we already covered in the latest section, as part of the optional stages of a whole house water filter.
But let’s go through the different types of whole house water filters:
Reverse Osmosis systems are quite powerful at removing contaminants from the water, as they can remove up to 99.9% total dissolved solids (TDS) from the water, effectively dealing with highly contaminated waters, like well water.
These systems can remove most of the contaminants from the water, like impurities, chlorine, fluoride, heavy metals, chemicals, bacteria, etc.
Because these systems remove so many particles from the water, they also remove healthy minerals (if in adequate quantities) like calcium and magnesium, so some systems included at the end of the process a remineralization stage to add back some of these minerals to the filtered water.
Typically these types of systems are more expensive than other types of whole house water filter systems, and they also generate waste water during the filtration process, which will increase your water bill.
One of the most common types of whole house filtration systems, and works well for most households that don’t have highly contaminated water.
On average it is not as expensive as other options, and because it has fewer filtering stages, it is also easier to maintain.
This system is good for dealing with chlorine, VOCs, dust, rust, impurities, and bad taste and odors.
Water Softener / Ion Exchange:
This type of filter’s main objective is to deal with the minerals in hard water, so it is good to replace contaminants like calcium and magnesium that can exist in excessive quantities in water but can also deal with sulfates and fluoride.
But by itself, it is not good at removing other contaminants that can impact the quality of your water, like microorganisms, viruses, and bacteria.
This type of water filter is great to deal with viruses, bacteria, and microorganisms, because it uses UV light frequencies to kill and remove those contaminants from the water.
Usually, this filter type has other filtration stages earlier in the process, to be able to remove most of the existing contaminants in the water.
Whole-House vs Reverse Osmosis Water Filtration Systems
If you are wondering if you should buy a common whole house water filter or a Reverse Osmosis water filtration system, you can check the table below to understand how they compare against each other for different features:
|Feature||Whole House Water Filter||Reverse Osmosis|
|Filtration||Good filtration systems with multi-stage filtration, capable of removing the most common water contaminants||Reverse osmosis systems offer a higher level of filtration, removing up to 99.9% of water contaminants|
|Location||The system is installed at the point of entry of the water in your house||Typically RO systems are installed to generate filter water for drinking and cooking purposes, in a kitchen as an under sink or countertop water filter.|
|Size||Large systems as need to have the capacity to filter all the house water||Medium-sized systems that can be installed under the sink|
|Capacity||These systems are designed to filter all the water of your home so they will have a large capacity. The filtered water is produced on-demand without impact on the water flow, to be used for all the purposes, from heather, sinks, toilets, appliances, etc.||but they’re slow and can only produce a limited number of gallons per day.|
|Installation||A more complex installation process, but that you can do by yourself||Simple to medium complexity installation, depending on if it’s an under sink or countertop RO system|
|Cost||Expensive, but will depend on the type and capacity||Average price, typically cheaper than a whole house water filter|
|POE or POU||Point-of-Entry||Point-of-Use|
There are also whole house RO water filters, but this is not what we are comparing on this table.
A Reverse Osmosis Whole House filter is not as common, because they are not that efficient. An RO system generates waste water, so to generate clean water for an entire household, even for uses that you don’t really need filtered water (like washing clothes or for toilets), it means wasting lots of water.
Also, most RO systems depend on a tank to store the filtered water, which is typically just for drinking purposes. If that is required for an entire household, a large system and RO tank are necessary, because they will cover the entire household water needs.
For these reasons, most RO systems are installed at POU (point of use) in a kitchen instead of at POE (point of entry), and can be combined with a normal whole house filtration system for the entire household.
Whole House Water Filter Benefits
Removes Contaminants & Impurities from Your Water
One of the main benefits of having a whole house water filtration system is to have access to clean and filtered water, in this case not only to drink and cook, like other types of water filters, but for all purposes in which you use water in your household.
A whole house water filter can remove different types of contaminants from the water, such as impurities, sediments, heavy metals, chlorine, arsenic, bacteria, viruses, nitrates, etc., ensuring access to clean water for your entire family.
Improve Water Taste & Odor
Another important benefit of a whole house water filter system is that it improves the taste and odor of your water because some contaminants are responsible for this.
For example, a common motive for the rotten egg taste of unfiltered water is the presence of hydrogen sulfide , which can be removed by certain whole house water filter systems.
Another benefit of a whole house water filter is the ability to filter all the water that enters your household, as it is installed at the point of entry, making sure that all the water is filtered before you use it.
So, if you need access to clean water in multiple places at your home, you will have it with a whole house water filter, while if you were using a POU (point-of-use) water filter you would have to install one in each place.
If you are a consumer of bottled water, you will heavily reduce the amount of plastic waste you create by starting using a whole house water filter, which is an environmentally friendly decision.
Apart from that, you will also save some money, as bottled water ends up much more expensive than filtered water, in the long run.
Contrary to other types of water filters, whole house water filtration systems are prepared to filter huge amounts of water without reducing its flow, so you will continue to have a normal water flow and water pressure at your home with this water filter type.
Whole House Water Filter Disadvantages
Whole House water filters are not small and need to be installed to the main water line before it enters your home, so you need to choose a good location for it, and make sure you have enough space to fit the water filter.
While you can find other types of water filters at affordable prices, whole house water filters aren’t typically cheap, as they need to have great capacity and filtration power to filter huge amounts of water.
Also, because you will filter all the water and not only the water that you will drink, the recurring costs associated with replacing filters will be higher than other water filter types.
Is a Whole House Water Filter Right For Me?
If you are looking for a whole house water filter, is because you are worried about the quality of the water of your home. That being said, you probably should have a water filter, but is a whole house water filtration system a good solution for you, or should you go with a more affordable solution, like an under sink or countertop water filter?
As mentioned before, it is important to first test your water to have an idea of the water contaminants of your water. Not all tap water and well water are safe, as they can be contaminated by different local sources, from industrial compounds to agricultural components. This will help you to understand if you need a whole house water filter, and which contaminants the filter needs to remove.
If your water has a bad taste and/or smell, a whole house water filter can be a good solution as this is usually caused by water contamination.
Another good reason to choose a whole house filter is if you and your family are currently buying bottled water. Moving to drink filtered water instead of bottled water, will save you money and will also have a positive environmental impact, as you will no longer generate lots of plastic waste.
If in general the quality of your water is acceptable, and you only want filtered water to drink and cook, you can probably choose another type of water filter. But if your water is heavily contaminated and you need to deal with the contaminants for the divisions of your house, a whole house water filter is the best choice.
