Omnipure - Q5655 - 12" x 2.5" Q-Series Twist Off DI Mixbed Filter
Q5655 Twist Off Deionization Filter
12" x 2.5" mixed bed DI cartridge with Twist Tap valve system for reliable TDS reduction in beverage, lab, and reverse osmosis applications
Mixed bed deionization for ultra-pure water output
Mixed Bed DI Resin
Combines cation and anion exchange resins to remove dissolved salts and minerals, reducing TDS to near-zero levels for polished, deionized water quality
Twist Tap Valve
Built-in shutoff valve automatically stops water flow when the cartridge is twisted off, preventing spills and making filter changes cleaner and faster
Q-Series Compatibility
Designed for existing Omnipure Q-Series heads with 1/4" Quick-Connect, 1/4" NPT, or 3/8" NPT fittings—drop-in replacement for current installations
Wide Application Range
Ideal for RO systems, ice makers, beverage equipment, lab use, and any application requiring low-conductivity or mineral-free water
Dimensions and fitment details
| Model Number | Omnipure Q5655 |
| Dimensions | 12" L x 2.5" W |
| Media Type | Mixed Bed Deionization Resin |
| Connection Type | Q-Series Twist Off (requires Q-Series head) |

Works with existing Q-Series systems
This Q5655 cartridge is a replacement filter and requires an existing Omnipure Q-Series filter head. Compatible with all Q-Series heads available in 1/4" Quick-Connect, 1/4" NPT female, or 3/8" NPT female configurations. Commonly used in reverse osmosis systems, ice machines, beverage dispensers, drinking fountains, laboratory equipment, and under-sink filtration systems where deionized or low-TDS water is required.
Replacement schedule
Typical Replacement
Replace when TDS levels rise or water quality decreases. Lifespan depends on inlet water quality and usage volume
Use a TDS Meter
Regularly test output water with a TDS meter. Replace cartridge when output TDS exceeds acceptable levels for your application
Protect the Resin
Use after sediment and carbon filters or an RO membrane to extend DI resin life and prevent premature exhaustion
Twist Tap Shutoff
No-mess filter changes with automatic water shutoff valve
Ultra-Low TDS
Mixed bed resin removes dissolved salts and minerals
Drop-In Replacement
Works with all Omnipure Q-Series heads and fittings
Commercial Grade
Trusted for beverage, lab, and RO polishing applications
