WaterFilters.NET can fill all your water treatment needs. Our goal is to make a site that makes it quick and easy for you to find the right drinking water filter system or replacement water filter cartridges. We have whole house water filters, under sink water filters, countertop water filters, faucet mount filters, water pitchers, shower filters, sport water bottles, water test kits, reverse osmosis systems, filtered water bottles, RV water filters, and more. We also supply many commercial filters. We take pride in being able to deliver the water filters you need. We have many authentic Culligan water filters and Pentek water filters.

Our water filtration products reduce the presence of sediment and chlorine taste and odor. Some of our products reduce the presence of contaminants such as mercury, lead, nitrates, herbicides, pesticides, giardia, cryptosporidium, and asbestos. If you are not sure what is wrong with your water, you may want to try a water test kit. The test kits will tell you which contaminants are in your water.

Many of the industry's water filter systems are made by a handful of manufacturers. For example, many interchangeable cartridges are available from Culligan, Ametek, Pentek, American Plumber, and USFilter brands. Other companies buy these water filters and put their own "brand names" on the filters even though the water filtration technology may be identical. For this reason, many water filter products are interchangeable. We have identified water filter products that are interchangeable with other brands in our "Search by Brand" pages. We have carefully chosen the highest quality and the most customer friendly water filter products to list on our site. If you cannot find the water filter you are looking for, check out our "How Do I Find My Water Filter?" page.

We hope you find the water filters you need. If there is anything we can do to help, please let us know.
