FAQs

How does reverse osmosis work?

What is reverse osmosis filtration used for?

Reverse osmosis removes over 99% of waterborne contaminants, making it ideal for applications that need pure water.

How long do reverse osmosis filters last?

RO membranes typically last 2 to 5 years while filters usually last between 6 and 12 months, depending on your system and usage. To maintain optimal performance, filters should be replaced annually.
