Doulton Water Filters & Filtration Systems

Doulton sets the standard for water filters and filtration products

Doulton water filters use ceramic water filter candles, which serve as a highly effective barrier against particles and pathogens as they remove all particles down to 0.2 microns (for maximum protection and the cleanest water), yet they leave all the beneficial minerals in the water. Whether you’re looking for a Doulton Whole House Filter System or a countertop water filtration system, you’re guaranteed to find everything you need to keep your Doulton water filter up and running.

With Doulton® ceramic water filters, you can have fresh filtered water for 12 months, if used on turbid water. No more changing water filters every 6 months, when the water filter gets dirty, simply clean it and reuse it, it’s that simple. For help finding the Doulton water filter or filtration system that’s right for you give us a call at 1-800-277-3458, we’re glad to help.
