The installation of this filter may be difficult without the help of a professional.
With a moderate price point and effective carbon filtration, the 3M Aqua-Pure Whole House Water Filter is our pick for the best whole house water filter overall.
This filter uses carbon media to reduce chlorine in water, helping with any taste or odor, and also helps to block other contaminants in the water supply. It’s helpful for well water or municipal water, and has three levels of filtration that eliminate sediment, particulate and rust, and scales as well.
This water filter is effective, while still providing a decent water pressure for the home, with high flow rates up to 20 gallons per minute. This is suitable for most residential and even light commercial needs.
We like that this water filter system is designed to allow for quick and easy filter changes (no wrench required) using just a quarter of a turn to remove the filter without needing to come into contact with any of the filter’s contaminants. This filter comes with a countdown magnet that you can put on the refrigerator to remind the user when to swap out the filter.
Keep in mind that the installation of this whole house filter is a bit more involved and could use the help of a professional as it requires you to have a pipe cutter, plumbing solder, torch, and more.

The GE Whole House Water Filtration System is the most affordable pick on our list while still effectively filtering sediment, scale, dirt, and rust from your water. It also is effective in eliminating chlorine, which is often used when treating city water.
This helps to improve the taste and odor of your home’s water. It does this by using a granular activated carbon filter and sediment filter, which effectively block any particles from making their way into your drinking water.
We like that this water filter is easy to install, and includes a 1-inch plumbing connection, pressure relief valve, bypass option, and mounting bracket, providing everything necessary to complete the job without professional help. You install this whole house filter by locating a horizontal pipe near your shut off valve, cut into it with a pipe cutter, and attach the filter using tools provided.
It also has a clear sump that allows you to view the filter easily so you know when it is time for a change. Additionally, there is a remote filter reminder light that you can install that will notify you when it’s time to swap the filter. The filter, according to the manufacturer, needs to be replaced every three months.
Keep in mind that this filter does not remove bacteria or heavy metals (like lead) from your water. While some whole house water filters can cost up to several thousand dollars, this budget-friendly model from GE is less than $100, making it the best filter for someone looking to clean their water without a hefty price tag.

The Aquasana Whole House Well Filter System may come with a hefty price tag, but if you use well water, it is well-worth the price. It has a capacity of 500,000 gallons, which translates to roughly five years of use.
The higher the capacity, the longer the filter life, which is especially helpful for homes with well water, as the water is completely unfiltered. Kourey says this whole house filter, “is tailor-made for homes utilizing well water sources, effectively safeguarding against the typical contaminants often present in private well water,” which can include lead, fluoride, chlorine, sulfate, and more.
What makes this filtration system different from others is that it has an upflow dual tank, which is helpful when it comes to keeping the tank from getting clogged and maximizes the water contact time with the filtration system, ensuring it is filtered well.
It has six stages of filtration, starting with the pre-filter, which captures rust, sediment, and silt. Then, water moves on to the rhine filter, a copper-zinc filter that includes activated carbon that helps inhibit the growth of bacteria and algae. After that, the water is filtered through the salt-free conditioner, which prevents minerals from binding and forming scale build up.
Then, there is the post-filter, which reduces any leftover sediment. Finally, the process is finished off with a UV filter that sterilizes bacteria and viruses, as well as cysts. If you don’t use well water, this water filter is still a great choice because it removes chlorine from water as well. Plus, the capacity means it will last longer, so you won’t need to switch it out as frequently.
Keep in mind that, in order to keep this filter system running at peak performance, you’ll need to replace the filters every two months. This means incurring an additional cost on top of the hefty price tag.

You’ll need to replace three filters every six months.
It’s important to note that every city’s water supply is different, which is why you should test your water to determine which contaminants will need to be removed. Thankfully, the Pro Aqua Elite Whole House Filter removes many of those contaminants, including lead, chlorine, copper, and iron.
This filtration system has three stages of filtering, including a sediment filter, an activated carbon filter, and a filter to remove heavy metals. Filtering out these contaminants is good not only for your drinking water, but for prolonging the life of your appliances.
Kourey calls this whole house filter an “easy and low maintenance option.” She adds, “The three-stage filtration system provides safe water for your entire home and removes up to 99% of chlorine, water-soluble lead, mercury, nickel, chromium, iron, rust, pesticides, dirt, sand, and many other contaminants,” making it a great option for those using city water.
We like that each filter has clear housing that lets you know when it’s time to change out the filters. Plus, the stainless steel pressure gauges make it easy to keep an eye on how the system is functioning. However, since it has three separate filters, this means keeping track of and changing three separate filters every six months, which cost $125 for a bundle.

This system cannot filter out sediment or heavy metals.
With UV light, Kourey explains, “water undergoes exposure to ultraviolet radiation within UV filters, effectively eradicating potentially harmful bacteria that pose health risks.”
Our pick for the best option with UV is the PENTAIR PUV-14 Whole House Water Treatment and Disinfection System because it uses a powerful UV light to eliminate E.coli, waterborne pathogens, fungi, viruses, and bacteria.
This filter has an exterior made of stainless steel, so it resists rust and corrosion, prolonging the life of your filter. The UV lamp has an indicator that lets you know the lamp should be replaced 30 days before, and if you forget to do so, there is also an indicator that comes on when it needs to be changed.
We love that this is an eco-friendly option, as it takes about the same power to operate as a low-wattage light bulb. Other filters may put your water through a carbon filter or sediment filter to remove contaminants, but UV filters use light to eliminate microorganisms, viruses, fungi, and bacteria. It is National Sanitation Foundation certified, which means it was independently tested and for guaranteed water disinfection.
This UV filter does not have the ability to filter sediment or heavy metals, so if you’re in an area where you find that you need these things filtered, you may want to choose another filtering system.

The iSpring Whole House Water Filter System is our pick for the best carbon water filter. Kourey explains, “A carbon block water filter effectively eliminates larger particles from water by attracting and absorbing sediment or silt.”
This whole house water filter removes rust, chlorine, herbicides, industrial solvents, sediment, and more thanks to its three-stage filtration system. The first stage is a polypropylene sediment filter that traps debris, and this particular filter is designed to allow for fewer clogs and minimal water pressure loss.
Next, there is a carbon block filter that uses coconut shell carbon to filter out other impurities. This also helps with the cloudiness of the water, the water’s color, taste and odor. Then, there is an iron and manganese filter that uses ion exchange to catch unwanted particles and reduces chlorine.
These filters have a capacity of 100,000 gallons, which is equivalent to one year of clean water, so you won’t have to worry about changing out the filter constantly.
Though this filtration system is designed to remove iron and manganese from your water supply, it will not be effective in catching lead. If you test your water and find that there is a presence of lead, you may want to choose a different filter.

“Municipal water treatment often utilizes chlorine to disinfect the water,” Kourey explains. “Residual chlorine compounds in your tap water may result in an unpleasant taste, odor, and can cause skin dryness and itching.”
If your water is showing high chlorine levels—and is tasting or smelling strange as a result—the AO Smith Whole House Water Filter System is our choice for chlorine removal.
Many filters remove chlorine from water, but what sets this model apart is that the central filter lasts for six years or up to 600,000 gallons of water. That means there’s no need to worry about changing the filter constantly in order to achieve drinkable or usable water.
In addition to removing chlorine from water, it also reduces mercury, chloramines, herbicides, pesticides, and more. However, it does not reduce sulfur or iron levels.
Keep in mind that this advanced granular activated carbon filter does not filter sediment or bacteria. If you want to do that, you’ll need to purchase add-ons, like A.O. Smith’s UV and Sediment filters.

You’ll need space for this system’s 3-gallon tank, which reserves clean drinking water.
Hard water is “characterized by high concentrations of minerals, typically calcium and magnesium ions,” Kourey says. “To fully address hard water issues, the use of a water softener alongside a whole house filter is necessary.”
The Aquasure Whole House Filtration System is our pick for filtering out calcium. This filter has a 64,000 grain water softener that minimizes scale and spot build up while treating hardness in your water supply.
In total, this system has five different filters. It also has a reverse osmosis under-sink system, which removes up to 99% of contaminants. Additionally, there is a sediment granulated active carbon (or GAC) pre-filter. This means this system not only guarantees softer water, it also filters out sediment and debris and reduces chlorine, copper, fluoride, and iron. The water softener system also eliminates iron and magnesium from your water supply.
On top of being effective, this water filtration system has a heavy duty, high-capacity tank that is corrosion resistant and reinforced with durable fiberglass.
Keep in mind that you’ll need space for this system’s 3-gallon tank, which reserves clean drinking water. The installation is also a bit more involved than other whole house filters, with one installation for the filter, one for the water softener, and one for the reverse osmosis, under-sink filter. This might be a headache if you’re handling the installation yourself.
