Doulton Countertop UltraCarb Water Filter Aquaman features the Doulton Countertop UltraCarb Water Filter Water Filter, a very high quality ceramic multi-stage water filter system. This unit is perfect for renters or those who want the convenience of portability without sacrificing contaminant removal. Most countertop systems are inexpensive low end systems designed to perform basic level filtration without much concern for high level dangerous contaminants. The Doulton Countertop UltraCarb Water Filter utilizes a combination of ceramic, carbon and deionization resin to remove a very long list of high level contaminants. This is as good as it gets without moving into an RO system which is a much larger system requiring significantly more maintenance. NSF certified to both standard 42 and the more stringent standard 53, the Doulton Countertop UltraCarb Water Filter is truly a high end countertop water filter system. Ceramic water filters have the added benefit of being washable and reusable, making them very long lasting. Furthermore, ceramic filters down to 0.5 microns, small enough to capture many microorganisms. Aquaman is a Water Quality Association Certified Water Specialist.
