Water Filter Housings & Maintenance

Water filter housings are used mainly on reverse osmosis systems and under sink systems to hold the cartridges in place.

We also have step by step instructions on installing replacement cartridges and sanitizing filter housings. It is highly recommended that you clean and sanitize your system once a year.
