“Well water filtration system” describes any device that removes contaminants from well water. There are many reasons to filter water, but namely, well water filtration systems are used to remove tap water contaminants, such as sediment particles, minerals, chemicals and bacteria.

There’s technically no difference between filtration systems for off-grid water sources, like wells, and those for any other residential water source. Although the details of how water filtration systems work vary depending on the type, the basic principle is the same: The water filter for your home is installed somewhere between the water source and the point of water use.

According to Derek Mellencamp, Aquasana General Manager and leading national water filtration expert, “While a large number of products have filtration systems, they vary in what they treat and the quality of the treatment.”

“Households tend to purchase point of use (POU) systems that sit under the kitchen sink and filter water out of a dedicated faucet,” he says. “These are a great option if you only want to filter the water you drink, as they’re typically more effective at reducing contaminants. Look for drinking water systems that are independently tested and certified to NSF/ANSI standards 42, 53 or 58 to remove the specific contaminants you want to address (i.e., were detected in your water test).”

Whole house filters are gaining popularity with thousands of homes making the switch to purify their drinking and bathing water. “Whole house filters treat all of the water coming into the home, so if you are on a well or have odor or color issues with your water, you can get filtered water from every tap in your home,” notes Mellencamp.

These systems come in various sizes and designs, and some are easier to install and operate than others. Because there are so many options on the market, it’s hard to nail down just one. However, there’s no need to dig for reviews—our shopping experts did the work for you. These are the 10 best well water filtration systems, backed by research and reviews.

Because it uses several different water filtration types, the system is capable of reducing organic chemicals including pesticides and herbicides in addition to the white flakes present in hard water.

However, water filtration isn’t always necessary for all well water. “The cheapest way to treat your well water is to do nothing after testing it,” says Mellencamp. “Some water is safe to drink right out of a well.” For most homes, that will not be an option. “Your water test results will likely indicate the minimum treatment level required to keep your water safe to consume,” he says.

“Regardless of the tests, it cannot hurt to buy a whole home filtration system with a sediment filter, a carbon filter and a UV filter. These systems ensure that bacteria and viruses are treated before consumption. In many cases, they will also improve the taste and smell of your water.”

Most of the well water filtration systems on this list require yearly filter changes, while a few need to be replaced more frequently. Some filters last for up to 10 years before they need to be replaced. “Filter changes are dependent on the type of filter used,” notes Mellencamp. “Most whole home filters require sediment filter changes every three to six months. UV bulbs typically last a year or longer. Whole home carbon tanks last anywhere from six months to 10 years.”
