RO Filter Changes

Have Your Filters Changed by our Minneapolis-St. Paul Water Filtration Professionals

If you have a Reverse Osmosis drinking water system in your home, we recommend that the filters be changed at least once every 10-12 months. Having your RO system serviced annually ensures that your membrane is still in good condition and that your system is still sanitized and effectively removing sediments and contaminants that add color or odor to your water.

Reverse Osmosis Filters


Reverse Osmosis filters provide screening, which traps the contaminants in the water as it flows through the filter. The specific type of filter required depends on the problem and the degree of its severity. If the contaminated particles are sufficiently large, the filter merely traps them. In other cases, a chemical reaction may first be necessary in order to make the particles of sufficient density to permit their collection on the screen.
