The Omnipure Q5755 water filter is user-friendly and can be used in icemakers, beverage equipment, drinking water fountains, RO systems, and undersink water filtration systems. Replacement of the spent media bed is done quickly by detaching the filter body from a permanent head with a twist of the wrist. The new Q5755 filter body is just as easily threaded into the head and the replacement is then complete. The Omnipure Q5755 water filter can be used with the optional Twist Tap in-head valve system, which automatically turns the supply water off when the body is disconnected from the head. The Omnipure Q5755 Deionization water filter reduces salt and TDS (Total Dissolved Solids) from your water.
