Using standard home water pressure, ultrafiltration pushes water through a semi-permeable membrane that removes contaminants, including bacteria, viruses, and parasites.1

Frequently asked questions about ultrafiltration
Below are some of the most common questions our customers have about ultrafiltration.
- Reverse Oosmosis systems have smaller pores, measuring around 0.001 microns, that filter out pollutants but also minerals that naturally occur in water. Ultrafiltration systems have larger pores measuring 0.02 microns. This allows Ultrafiltration systems to remove potentially harmful particles but keep beneficial elements like calcium and magnesium.3
