Omnipure - Q5321 - 6" x 2.5" Q-Series Twist Off Carbon Block Filter - 10 Micron
Q5321 6" x 2.5" Carbon Block Filter
The Omnipure Q5321 combines solid carbon block filtration with the convenience of a twist-off design that automatically stops water flow when you disconnect the cartridge. Built for 2.5" x 6" installations at 10 micron rating, it handles chlorine taste and odor removal across residential and commercial applications without the hassle of shutting off your water line.
What Makes the Q5321 Different
Twist Tap Valve System
Built-in shut-off valve automatically stops water flow when the filter body is disconnected from the head, eliminating the need to turn off supply lines during changes
Carbon Block Media
Solid carbon block construction provides consistent 10 micron filtration with superior chlorine taste and odor reduction compared to granular carbon
Compact 6" Length
2.5" diameter x 6" length fits tight installations where standard 10" cartridges won't work, ideal for under-sink RO systems and inline applications
Universal Q-Series Mount
Compatible with all Omnipure Q-Series heads in 1/4" quick-connect, 1/4" NPT, or 3/8" NPT configurations for flexible installation options
0.5 GPM Flow Rate
Balanced flow rate supports ice makers, refrigerators, beverage equipment, and drinking fountains without excessive pressure drop
1000 Gallon Service Life
Rated for 1000 gallons or 12 months of service, whichever comes first, with max operating pressure of 125 PSI and temperature up to 100°F
Where the Q5321 Fits
The Omnipure Q5321 is a replacement cartridge that requires an existing Q-Series filter head. It's designed for under-sink reverse osmosis systems, refrigerator water lines, ice maker installations, beverage dispensers, drinking fountains, and inline water filtration applications where space is limited and chlorine removal is needed. The proprietary Q-Series twist-off design is not compatible with standard filter housings. Heads are available separately in 1/4" QC, 1/4" NPT female, and 3/8" NPT female thread configurations.
Omnipure has been manufacturing inline water filters in the USA for over four decades, trusted by equipment manufacturers and water treatment professionals worldwide.
