I don't need it to remove air from water, I need it to stop mixing air that was in the empty spaces around filters when they were installed into said water. Tap water doesn't have much air in it I don't think, it will sort itself out eventually. Right now I have very small air bubbles that are still visible when filling up a glass, they are created when air and water pass through RO membrane. After you let it sit for a while PPM number drops.
