For this post, I have put together a collection of the best whole house water filters currently available.

Updated: July 3, 2019.

Standard “point-of-use filters” such as water jugs, tap purifiers, and refrigerator water filters offer the ability to filter the water where you need it. However, these methods are time consuming and are only effective if installed on every fixture of your house. A more efficient technique is a “whole house” filter system.

What is a whole house filter?

Whole house filters differ from point-of-use-filters by being located at the water source for your home. The filter is installed at a junction before it reaches your individual water fixtures. This allows for the distribution of filtered water to your kitchen sink faucets, bathroom faucets, shower heads, washing machine, etc.

Types of Drinking Water Contaminants

Physical contaminants: sediment or organic material suspended in the water of lakes, rivers and streams from soil erosion.

Chemical contaminants: naturally occurring or man-made. Examples: nitrogen, bleach, salts, pesticides, metals, toxins produced by bacteria, and human or animal drugs.

Biological contaminants: organisms in water. Examples: bacteria, viruses, protozoan, and parasites.

Radiological contaminants: chemical elements. Examples: cesium, plutonium and uranium.

Common Whole House Water Filter Features

Flow rate - gallons per minute (GPM). Standard requirements will vary from 15 - 40 GPM depending on your total fixture counts and individual flow rates.

Filter life - replacement cycle based on the filter type, level of water contaminants and flow rates.

Port size - connection point diameter. Minimum ideal port size is 1" to avoid pressure drops.
