Q5321-P 6" x 2.5" Carbon Block with Phosphate Filter
The Omnipure Q5321-P combines carbon block filtration with polyphosphate treatment in a compact 6-inch body. Designed for RO systems, beverage equipment, and ice machines where both taste improvement and scale prevention matter. The Q-Series twist-off body design means replacement takes seconds, not minutes.
What Makes the Q5321-P Different
Twist-Off Body
Replace the entire filter body in seconds without tools. Permanent head stays mounted, only the cartridge body needs changing.
Carbon Block Media
10 micron carbon block removes chlorine taste and odor while providing depth filtration for sediment and particulate.
Phosphate Treatment
Integrated polyphosphate inhibits scale formation and corrosion, protecting downstream equipment and extending component life.
Compact 6" Length
6" x 2.5" diameter fits tight spaces under sinks, in RO housings, and beverage equipment applications where space is limited.
Optional Twist Tap
Available with in-head valve system that automatically shuts off water flow when body is disconnected. No drips or mess.
Proprietary Q-Series Fit
Works exclusively with Omnipure Q-Series heads. Available with Quick-Connect 1/4" or NPT threaded connections in 1/4" and 3/8".
Where the Q5321-P Works
The Q5321-P is designed for reverse osmosis pre-filtration, ice machines, beverage dispensers, drinking water fountains, and any point-of-use application requiring chlorine reduction and scale prevention. Compatible with all Omnipure Q-Series permanent heads and housings. The 6-inch length is the shortest Q-Series option, ideal for compact installations. Common applications include under-counter RO systems, commercial ice makers, and inline beverage equipment. Use with Omnipure Q-Series heads featuring 1/4" Quick-Connect or 1/4" and 3/8" NPT female threaded fittings.
Omnipure has been manufacturing inline water filters for decades. The Q-Series design prioritizes simplicity and cost-effectiveness without sacrificing filtration performance.
