How a reverse osmosis drinking water system works
There are four distinct steps in reverse osmosis water filtration - pre-filtration, reverse osmosis, drainage and storage.
Multi-stage filtration for better water

- Carbon filter tackles bad tastes and odors, like chlorine
- Reverse osmosis filter reduces contaminants like lead, mercury, chromium and more
- Advanced specialty filters reduce pharmaceuticals, virus, bacteria and more
- Custom filters add minerals back in and increase the water’s PH
