Find the Perfect Whole House Water Filter: A Comprehensive Buyer's Guide
There are many whole house water filters available on the market, ranging from UV water filters to high efficiency designs. These filters can be further divided into categories based on their capacity, installation style, and filter design.
Before we delve into the factors to consider when choosing a whole house water filter, let's first discuss the different types of filters available.
Types of Whole House Water Filters
If you're considering a whole house water filter, you'll want to know about the different types available.
1. Mechanical filters: Remove Physical Particles
When you want to remove physical contaminants from water, such as sediment, sand, and dirt, mechanical filters should be your choice. These filters work by using a physical barrier that traps and removes contaminants as water passes through the filter.
Sediment filters are a type of mechanical filter that use a fine mesh or a series of layers of media to catch rust, dust, and other types of sediment. They are typically made of pleated paper or fiberglass and can be easily replaced when necessary.
On the other hand, another type of mechanical filter, reverse osmosis (RO) systems, uses a membrane to filter out contaminants by forcing water through a semi-permeable membrane. This process only allows water molecules to pass through and removes larger contaminants. While RO systems are highly effective at removing chemicals, impurities, and microorganisms, they also remove beneficial minerals such as calcium and magnesium from your water. This reduces the overall mineral content and can affect the taste and potential health benefits of the water.
If you're in the market for a whole house water filter that utilizes reverse osmosis technology, be sure to check out our comprehensive guide to the best whole house reverse osmosis systems. Our expert team has thoroughly researched and reviewed the top options available to help you make an informed decision.
2. Chemical filters: Remove Impurities and Other Contaminants
As the name indicates, chemical filters use a chemical process to remove contaminants from the water.
Carbon filters are the most common type of chemical filter that uses activated carbon to remove impurities, such as chlorine and chemicals, from the water supply. These filters work by using adsorption to remove contaminants from the water by attracting and holding them on the surface of the filter media.
It's important to note that these filters don't necessarily make the water safer to drink or use; they just make it taste and smell better.
If you're looking to get rid of a specific type of contaminant from your water, there are whole house water filters that are specifically designed for this purpose:
- 5 Best Whole House Water Filters for Chlorine
- 6 Best Whole House Water Filters for Lead
- 7 Best Iron Filters for Well Water
If you live in an area with hard water – which is the case 90% of Americans do – then you may want to consider a water softener to soften your water in an additional stage. Water softeners remove these minerals from your hard water supply, preventing scale formation and helping to extend the lifespan of your plumbing appliances and reducing the need for descaling.

Some water softeners requires a salt-based system that extracts minerals from your water supply and replaces them with sodium. However, this type of system can be bulky and may not fit in the space available in whole-house systems.
An alternative option is to use a whole-house water filter with an electronic descaler. While electronic descalers won't fully soften your water, they can reduce the impact of hard water by preventing minerals such as calcium and magnesium from bonding with your pipes and appliances.

3. Biological filters: Remove Bacteria and Viruses
Biological filters work by using living organism or processes to remove contaminants from the water.
As the name suggests, UV water filters use ultraviolet light to purify water. This light kills or inactivate microorganisms such as bacteria and viruses in the water, making it highly unlikely that you will get sick from drinking water that has been treated with it.
UV water filters are not the primary choice, except in situations where there is a genuine concern about bacteria and waterborne viruses. They are a popular addition to various types of whole house filters, particularly, high-efficiency systems.
4. Multi-Stage Highly Efficient Filters: Combo of Multiple Water Filters
High efficiency whole house water filters offer a comprehensive solution for improving the water quality in your home. They combine two or more types of water filtration technologies such as carbon block filters, sediment filters, and granular activated carbon block filters, to remove contaminants from your water. Additionally, they use a process called Kinetic Degradation Fluxion (KDF), which uses high-purity copper and zinc particles to remove heavy metals, chlorine, bacteria, and algae through an oxidation/reduction reaction.
These filters are typically multi-cartridge, meaning you may need to change more than one filter every six months or so. However, the extra effort is well worth it as you'll be getting water that is free of heavy metals, chlorine, and bacteria.
Keep in mind that high efficiency whole house water filters can be quite expensive compared to other options on the market. They may cost 2-3 times more. But if you're concerned about the potential health risks of drinking water that may not be safe, a high-efficiency whole house water filter may be the best choice for you.
Key Considerations for Selecting a Whole House Water Filter
It's important to carefully consider these factors when choosing a whole house water filter to ensure that you get the best one for your needs.
Removal of Contaminants
When you're drawing untreated water from a well, there are plenty of contaminants that may be present. Understanding what's in your water supply is crucial when it comes to finding the perfect whole house water filter for your family. Different systems target different contaminants, so it's important to know what you need to remove.
For example, a system targeting taste and odor will remove chemicals like chlorine and sediment, while a high-efficiency system can target a wider range of contaminants, such as heavy metals (like iron, lead, and arsenic), bacteria and viruses, sediment, and pesticides.
Here's a list of some of the contaminants that an effective whole house water filter might remove:
- Microorganisms (e.g. bacteria, viruses)
- Volatile organic compounds (VOCs) (e.g. benzene, chloroform, trichloroethylene)
- Heavy metals (e.g. cadmium, chromium, nickel)
- Total dissolved solids (TDS)
It's important to find a whole house water filter that targets the specific contaminants in your local water supply. Some contaminants, like hard water, are easy to spot through a visual inspection of your pipes or appliances. Sediment and rust will also be evident in a cup of water. However, other contaminants like total dissolved solids, chemicals, and bacteria are invisible to the naked eye.
To find the best whole house water filter for your well water, it's recommended to use a testing kit to determine the specific contaminants present in your water. This will allow you to effectively target and remove these contaminants, ensuring the safety and quality of your water.
Size and Capacity
When it comes to water filters, size does matter. If you undersize your whole house water filter system, it won't perform as well and may not even filter your water properly. This can end up costing you more in the long run, as the individual filter cartridges may not be able to handle the demand for water.
Whole house water filters can range in capacity from 10,000 gallons to as much as 1,000,000 gallons. A capacity of 100,000 gallons is more common. To determine the right capacity for a whole house water filter, consider your family size, water usage and water quality.
- For a family of four with moderate water usage and average water quality, a whole-home water filter with a capacity of 20,000 to 23,000 gallons may be sufficient.
- For a family of six with high water usage and water with high levels of contaminants, a whole home filter system with a capacity of 50,000 to 60,000 gallons may be needed.
- For a family of two with low water usage and relatively better water quality, a whole house water filter with a capacity of 10,000 gallons may be sufficient.
|Whole Home Filtration System||No. of Bathrooms|
|Home Master HMF3SDGFEC||4+|
|Express Water (3-stage)||1-4|
|Aquaboon 12 Inch||1-2|
Besides capacity, another concern for your water supply is the flow rate. Flow rate is a measure of how fast your filter system can actually filter the water.
When you run your entire water supply through a filter at the point of entry to your home, it's inevitable that the flow rate will be slowed down. It's a nightmare you don't want to consider. Why have perfectly pure water if you can't even use it properly?
Different appliances in your home require different amounts of GPM. For example:
- Toilets: 2-3 GPM
- Showers: 1.5-3.0 GPM
- Faucets (bathroom or kitchen): 2-3 GPM
- Dishwashers: 2-4 GPM
- Washing machines: 3-5 GPM
To get an idea of how much GPM you need in total, you can add up the GPM requirements of all the appliances you have. For example, if you have a toilet, a shower, and a kitchen faucet, you will need at least 7 GPM (2 GPM for the toilet + 3 GPM for the shower + 2 GPM for the faucet). Having a high flow rate ensures there's enough water for everyone in the family.
|Whole Home Water Filter System||Flow Rate (GPM)|
|Aquasana Rhino||37 GPM|
|SpringWell CF1||9-20 GPM|
|AquaPure AP903||20 GPM|
|Express Water (3-stage)||15 GPM|
|GE GXWH40L||15 GPM|
|iSpring WGB32B||15 GPM|
|Home Master HMF3SDGFEC||15 GPM|
|Aquaboon 12 Inch||10 GPM|
|Whirlpool WHELJ1||6 GPM|
|DuPont WFPF13003B||5 GPM|
Importance of Micron-Level Sediment Targeting
Sediment in your drinking water can be an unpleasant surprise. It can range from harmless grit to a potential health concern, such as rust. Most whole house filters are designed to target sediment to some extent, but it's important to keep in mind that these contaminants come in many different shapes and sizes.
Sediment is typically measured in microns, which is equal to one-millionth of a meter. Some premium whole house water filters are able to remove anything larger than one micron, while cheaper models may not be as effective and may let particles smaller than 50 microns pass through.
One downside of exceptional sediment filtering is that it can sometimes result in a slower flow rate. If you go for a filter that is too effective at filtering out microscopic particles, it can actually end up choking your flow rate.
Ease of Maintenance: Filter Lifespan
While we're talking about filters, it's important to consider their lifespan. No filter lasts forever and with any whole house water filter system, you'll need to replace individual filter cartridges on a regular basis.
Sediment filters typically need to be replaced every six to twelve months, while other cartridges can last much longer. If your filters last twice as long, that means you'll have to replace them half as often, which can save you money in the long run.
Just keep in mind that these guidelines are based on average water usage. If you've a large family, you may use more water and need to replace your cartridges more frequently. On the other hand, if you're single or environmentally conscious, you may use less water and be able to go longer between cartridge replacements. So, when choosing a water filter system, consider not just the upfront cost, but also the long-term cost of replacing the filters.
Remember to pay attention to any changes in the taste and smell of your water to determine when you need to replace any of them.
If you forget to change your filters, particularly the sediment ones, you may experience clogging within your system. Additionally, an old filter will not effectively filter your water, potentially leading to bacterial growth and worse water quality than if you didn't have a filter at all.
|Whole Home Filter System||Filters Lifespan||Filters Replacement Cost|
|SpringWell CF1||every 6 to 9 months||$20 per piece (~$3.3/month)|
|Aquasana Rhino||every 6 months||$19 for a pack of 3 (~$3.2/month)|
|Home Master HMF3SDGFEC||every 6 to 10 months||$85+ (~$14+/month)|
|Express Water (3-stage)||every 9 to 12 months||$190+ (~$20/month)|
|iSpring WGB32B||every 6 to 12 months||$100+ (~$16/month)|
|DuPont WFPF13003B||every 6 months||$15+ (~$2.5/month)|
|AquaPure AP903||every 12 months||$120+ (~$10/month)|
|GE GXWH40L||every 3 months||$5+ (~$1.6/month)|
|Whirlpool WHELJ1||The unit will have to be replaced||–|
|Aquaboon 12 Inch||every 2 months||$10+ (~$1.6/month)|
When you see a bold claim that 99.99% of bacteria are eliminated, you may want to verify whether the brand can actually back it up. One way to do this is to look for certification from the National Sanitation Foundation (NSF), which works with the American National Standards Institute (ANSI) to provide a standardized classification system for water filter systems. The NSF offers several different classifications, certifying that water filters remove chlorine, chemicals, and bacteria.
It's important to be aware of the different classifications offered by the NSF:
- NSF/ANSI 42: This classification is commonly found on taste and odor filters that can certify the removal of chlorine and large sediment.
- NSF/ANSI 44: This certification is relevant for water softeners and indicates the removal or reduction of calcium and magnesium. If you have hard water, this is a certification to look for.
- NSF/ANSI 53: Filters with NSF/ANSI 53 certification are able to remove significant contaminants such as metals like lead and chromium, as well as volatile organic compounds (VOCs).
- NSF/ANSI 55: This certification is specific to UV water filters that target bacteria and other bugs in the water.
- NSF/ANSI 58: This certification is for reverse osmosis water filters and confirms the removal of heavy metals like copper, arsenic, and lead, as well as the reduction of total dissolved solids.
- NSF/ANSI 401: This certification is less common among whole house water filters, but it certifies the removal of prescription drugs, new herbicides, and other complex compounds.
- NSF/ANSI 244 and 231: These certifications are commonly found on water filters for backcountry and camping use, and they certify the removal of microbiological contaminants and microorganisms that can contaminate drinking water.
Some big-name brands may offer independent lab tests for their filter systems that are not affiliated with the NSF.
Remineralization: The Process of Restoring Minerals
Post-filtering remineralization is an often-added feature of whole house water filters that can help make your water taste crisp and drinkable again. This process adds back in minerals that were removed during filtration process such as reverse osmosis, providing not only better taste, but also nutritional benefits. If you're interested in this feature, be sure to look for it on premium models.
Some high efficiency filters that bring your TDS to an exceptionally low level often remove harmless minerals such as calcium, sodium, and magnesium from your water, which can leave it tasting boring and bland.
The Installation of Whole House Water Filter
Whole house water filters can be quite complex systems. Some units are suitable for self-installation, while others may require the assistance of a professional plumber. It's important to check which components are included and whether the brand recommends self-installation. Keep in mind that even if a filter advertises DIY installation, professional installation may still be required as part of the warranty's terms and conditions. It's not worth risking voiding your warranty on such an important investment.

Space and Location
Point-of-entry filter systems are larger and bulkier than under-sink or faucet water filters. Make sure you have enough space for your chosen model, and if you're planning to install it outdoors, ensure it can withstand the winter temperatures in your area.
There are whole house water filters available at various price points, so you can find something that fits your budget. If you're looking for a basic model, you can find options starting around $300 that offer adequate filtering for single-person households. On the other hand, if you want maximum filtering, you may need to spend upwards of $2000 for a premium brand.
The Whole House Water Filter FAQ
Here's a final FAQ to clear up any last drops of doubt about choosing the perfect whole house water filter for you and your family.
Do I need a whole house water filter?
It's understandable to wonder if you need a whole house water filter, as it's a big investment. However, there are certain circumstances in which a whole house system may be necessary. For example, those living off-grid or in a home with older plumbing may need to deal with contaminants such as lead, iron, or bacteria.
On the other hand, even those in newer homes with city-provided water can benefit from a whole house water filter. The taste and feel of the water can be improved, and if you're concerned about chlorine or fluoride being added to your water, a whole house filter can provide a solution.
What contaminants should I worry about?
These can include rust, grit, sediment, harmful chemicals, and metals. These contaminants can not only affect the taste and texture of your water, but they can also be harmful to your health.
According to the Centre for Disease Control (CDC), some of the main contaminants to be aware of include arsenic, lead, iron, bacteria such as E. coli and giardia, industrial chemicals (VOCs), and pesticides like methoxychlor and chlordane.
Will a whole house water filter soften my water?
The majority of whole house water filters don't soften your water. However, some premium filter systems include an electronic descaling stage that can reduce the negative effects of hard water on your plumbing and appliances.
For true water softening, you will need a separate reverse osmosis water softener. These salt-based systems remove the hard minerals from your water completely.
I understand that investing in a whole house water filtration system can be a significant expense. That's why it's important to carefully consider your needs before making a commitment, especially if you'll also have to pay for installation. However, there are options available at a range of price points.
One highly-recommended option is the 3M AquaPure. It's a great whole house system that can handle most contaminants, except for heavy metals, and it's priced significantly lower than some of its competitors.
If you do need to deal with heavy metals from well water or an older home, the Express Water system is a good choice. It's easy to install and provides good value for the price.
For filters that only address taste and odor issues, the Whirlpool WHELJ1 whole house filter system is a solid choice. It has a self-cleaning filter that eliminates the need for regular maintenance and is relatively easy to install if you have basic handyman skills.
Another option is building your own system using the Aquaboon Big Blue housing, which allows you to customize your system with a variety of filter cartridges. However, this option requires some plumbing skills.
No matter which filter you choose, it's important to make sure it's suitable for the makeup of your water. If you can't afford a high efficiency POE system, you can also consider adding additional filters under the sink.
