Types of Water Filters
There are a few main categories of water filters, each with pros and cons depending on your needs.
Under Sink Water Filters

Undersink water filters connect to the plumbing under your sink (usually the kitchen) and provide filtered water through a dedicated faucet.
With a reverse osmosis (RO) membrane as one of the stages, these filters offer the best value since they produce LOTS of clean, filtered water.
Reverse osmosis water filters are also the most common filter type installed in the home.
Countertop Water Filters

Countertop water filters come in a variety of shapes and sizes. Some connect to the faucet, some only need electricity, and some just use gravity.
This is the easiest way to get clean, filtered water in any situation!
Whole House Water Filters

If you want to be sure that ALL of the water in your house is safe and that every faucet and appliance is protected, then you need a whole house water filter.
Available in sizes and budgets for every home, this is the best way to be sure you’re covered.

The Environmental Working Group (EWG) recommends reverse osmosis water filters as the “most effective” way to filter your drinking water since it will remove up to 99% of common and dangerous contaminants.
