How to Filter Your Well Water for Drinking

Many homes in the United States source their water from private wells. Wells can be a cheap source of water, saving you money on your water bill each month. That benefit can come with a cost, though. Well water must be filtered and purified to maintain a high quality. Without proper filtration, your water could make you sick!

Why You Need to Filter Your Well Water

Most wells are not regulated by the Environmental Protection Agency (EPA). Private wells without that government regulation usually don’t have safety mechanisms in place to test and maintain the drink-ability of their water. This can be a major concern. Unfiltered well water can have a host of issues that may affect a drinker’s health, including disease-carrying pathogens, sediment and dirt contamination, and a presence of rust or heavy metals. Unfiltered well water can also have unsightly color, pungent odor, and bad taste.


While the United States has some of the cleanest water in the world, any water source not government-regulated can be at risk of contamination. Bacterial and fungal contamination can spread infection and disease. Filtering your well water won’t necessarily sift out every waterborne pathogen, but filtering can greatly reduce the chances for contamination.


Flooding, ground disturbances, and movement in the earth can cause your aquifer or well to fill with sediment and particulate. Sand, dirt, and silt are all common contaminants. While microscopic levels of these particulates are essentially harmless, larger quantities can cause sickness. Water filters are especially good at removing hard particulates like those mentioned above and can drastically improve water quality.

Rust and Heavy Metals

Rust and heavy metals can also be a concern depending on where your well is located and the delivery devices you’re using to transport water from the well to your tap. Metal piping will naturally rust over time, which can lead to metal flakes being deposited into your water. Nobody wants to drink down a glass of metal shavings! Naturally-occurring metals like zinc and iron can also be present in your well or aquifer, which in large doses can be harmful to the human body.

Color, Odor, and Taste

Besides all the health concerns, unfiltered water is also ugly. Your water can take on a dirty color, have a terrible smell, and taste awful without proper filtration. These can be serious drawbacks when you’re using your well water to drink and bathe and cook. Using a proper filter will keep your water looking, smelling, and tasting fresh!

How to Filter Well Water

Luckily, filtering your well water can be as easy as finding the right well water filter. There are several options, from whole house water filters to countertop filtration. This video does a great job of explaining each kind of filter, and the sections below describes them in detail.

Whole Home Filtration

These systems, also known as “whole house” filters, are large components attached to all the main pipes in your home. You can think of them like a set of kidneys. Your well water is fed into these systems, usually via an automatic pump, and filtered in large containers. The purified water is then dispersed throughout the rest of your home. They can be found at most home-goods stores and online retailers. Most companies offer professional installation. You will probably have to make modifications to your plumbing to accommodate these systems.

Under-the-Sink Filtration

Smaller water filters can be installed under your sink, attached to your home plumbing. These can filter large amounts of water, but not as much as a whole home system. They only provide local filtration of the sink to which they’re attached. Again, they can be found at most home-goods retailers. You’ll likely need to make small alterations to your home plumbing to accommodate these types of filters.

Countertop Filtration

These filters are attached directly to the faucet or tap and usually require very minimal to no plumbing alterations (or knowledge). They filter the smallest quantity of water between the three options listed here but take up the least space and require the least knowledge to install. Like under-the-sink filters, they will only filter the water coming through the sink to which they’re attached.

Best Well Water Filters

From whole house water filters to emergency drinking water options, here are the best well water filters.

Propur Dual Stage Filter Countertop System

This dual-stage Propur system will definitely do the trick. It’s built to last and extremely reliable, but it’ll take up a lot of space on your counter. The Propur is inverted, like most countertop systems, which means an air bubble can form at the top of the filter. It might be best to invert everything when attaching the filter to the base.

It’s very important that you filter your water, however you get it done. This is always true, but especially if you’re using well water. Having access to a private well can be a freeing experience, but it shouldn’t come at the cost of your health. Investing in proper water filtration can be costly in the front end but will pay for itself in the long haul. Always ensure you do your own research before making any big purchases — especially when it comes to something as important as water purification. It never hurts to consult professionals either.
