FAQs

How do Reverse Osmosis Systems work?

Reverse Osmosis (RO) systems work by using a semipermeable membrane to remove contaminants from water. Water is forced through the membrane under pressure, and the membrane allows water molecules to pass while blocking impurities, including minerals, bacteria, and chemicals. The result is purified water on one side of the membrane and concentrated contaminants on the other.

What is Reverse Osmosis filtration used for?

Reverse Osmosis filtration is used in various applications where the need for exceptionally pure water is crucial, such as drinking water, dentistry, and aquariums. They are capable of removing up to 99+% of waterborne contaminants.

How often should you drain an RO system tank?

For RO systems that have storage tanks, we recommend draining them about every two weeks to ensure that the membrane can adequately supply you with clean water.
