Omnipure Quick Change Q-Series Filter Cartridges


As with all Omnipure filters, the Q-Series is ideal for use in any situation where better tasting, sediment-free water is required – beverage equipment, RO systems, drinking fountains, ice machines, and other point-of-use applications.



Filtration Process

Omnipure filter cartridges Standard media includes granular activated carbon for taste and odour reduction, polypropylene depth filtration for removal of grit and sediment, and polyphosphate to control lime and scale deposits. Also, a wide variety of specialty and custom media options are available.

Replacement of the spent media is quick and simple, by detaching the filter body from a permanent head with a twist of the wrist. The new filter body is just as easily threaded into the head and the replacement is then complete.

The Q-Series is also available with the optional Twist Tap in-head valve system, which automatically turns the supply water off when the body is disconnected from the head. No tools. No drips. No hassles.

Cartridge variations

Dependent on your specific filtration needs – Omnipure provide a range of cartridges specialized in removing particular contaminants.
