DC-1804R Water Filter System
Buder DC-1804R/DC-1805R ultrafiltration water system removes contaminants from your drinking water while retaining beneficial minerals. Chemical contaminants, bacteria, and viruses cannot pass through the ultrafiltration (UF) membrane, and the activated carbon filters reduce chlorine taste and odor. Buder UF water system fits directly under your sink for convenient access.
Product Functions:
- Environmental protection: This ultrafiltration water system produces no wastewater, eliminating the need for a storage tank.
- Quick filter replacements: Innovative twist and quick-change filter cartridge design, no tool required for more simple and sanitary replacements.
- The Ultrafiltration filtration system comes with a UF membrane made of hollow fabric, with the aperture of the fabric less than 0.1 micron, so it can remove bacteria, viruses, and other pathogens
- Retention of key minerals that are beneficial to people drinking the water
- Installs quickly and easily
