The Ora RO System removes chemicals, contaminants, and up to 99% of mineral salts that contribute to the hardness of water. It uses 4 levels of filtration, so you’re left with only clean, pH neutral water that is ideal for use with everything from humidifiers to hydroponic systems and for mixing powdered nutrients.
Ora RO machine processed water produces no powdery residue, which also protects your equipment and increases the useable life of your expensive hydroponic products too.

The easy-to-read digital display on each filter’s usable life and indicates when replacements are required.
