Doulton is one of the world’s largest makers of ceramic filters. For over 185 years, Doulton has made eco-friendly, reusable cartridge filters. Their goal is simple: They provide safe, healthy, great-tasting drinking water anytime, anywhere you need it.

Why Doulton Water Filters?
Doulton ceramic filters are world-famous for good reason. Fairey Industrial Ceramics Limited (FICL) is the sole manufacturer of the Doulton ceramic water filters. All stages of FICL’s drinking water filter production adhere to rigorous ISO 9001 quality standards.
Fairey Industrial holds the Water Regulations Approval Scheme (WRAS) and National Sanitation Foundation (NSF) certificates. WRAS is the United Kingdom’s approval body for drinking water fittings and materials. NSF is the United States standard for drinking water filters.
These coveted certifications demonstrate that these drinking water filters meet the highest international testing standards. High standards are why the Doulton brand name is well known and trusted for home water filters in the United States and abroad.
Are Doulton and British Berkefeld the same company?
Yes, Doulton and British Berkefeld are the same company. British Berkefeld is a registered trade name for Douton. This means you will see brand names quite often when shopping for ceramic water filters and gravity-fed water systems.
What to Look for in a Water Filter or Filtration System
If you are looking for the right water filter or filtration system for your home, here are a few things you should consider:
- Water Supply: In the United States, the two most common water sources are wells and municipal water systems.
- Water Quality: What water contaminants are you most concerned about? Common water quality challenges include excess sediment, chlorine taste and odor, and even bacteria. Water quality varies from location to location. Considering your local water quality is essential when exploring potential water filtration solutions.
- Maintenance: Don’t forget to account for the filter’s longevity and maintenance. A great benefit of choosing ceramic filters is that they will last a long time. Ceramic water filters are reusable and easy to clean. This not only saves money, but also helps reduce waste—a win-win for your wallet and the environment.
Once you’ve narrowed down your choices, you’ll also want to account for the following:
- Filter capacity: How much water do you use daily? You’ll want to ensure the system can keep up with your household’s demand.
Installation and maintenance: Ask yourself: Will you hire a professional or install the system yourself? What will daily, weekly, and monthly maintenance look like? How often will you need to clean or replace the filter? - Certifications: Will the filter reduce or remove the contaminants that you need it to? Make sure the filter you use has NSF/ANSI or WRAS certification. This will help ensure your water is safe to drink.
- System type: Which water filtration system best meets your space and household’s needs? You’ll need to decide between a whole-house, countertop, or undersink system.
Taking these factors into account is essential when choosing a water filter or filtration system that works for you.
