Omnipure - Q5405 - 8" x 2.5" Q-Series Twist Off Sediment Filter 5 Micron
Q5405 8" x 2.5" Twist Off Filter with In-Head Valve
The Omnipure Q5405 is a sediment prefilter designed for the Q-Series twist-off system, featuring an integrated Twist Tap valve that automatically shuts off water flow when you disconnect the filter body. Built with polypropylene melt-blown media, it captures dirt, sand, and sediment down to 5 microns at flow rates up to 0.5 GPM, making it ideal for protecting RO membranes and extending system life in residential and commercial applications.
Filter Performance & Dimensions
| Model Number | Q5405 | Filtration Type | Melt-blown polypropylene |
| Dimensions | 8" L × 2.5" W | Micron Rating | 5 micron |
| Flow Rate | 0.5 GPM | Service Life | 3000 gallons or 1 year |
| Max Pressure | 125 PSIG | Max Temperature | 100°F |
| Valve System | Twist Tap in-head shut-off | Connection Type | Q-Series twist-off head |
Why the Q5405 Works
Twist Tap Valve
Integrated shut-off valve in the filter head automatically stops water flow when the cartridge is removed, preventing spills and allowing tool-free filter changes
Depth Filtration
Polypropylene melt-blown construction provides graduated pore structure that captures particles throughout the entire filter media depth
5 Micron Sediment
Removes dirt, sand, silt, and rust particles down to 5 microns, protecting downstream equipment and preventing premature fouling of membranes
Universal Q-Series
Compatible with existing Omnipure Q-Series heads in 1/4" quick-connect, 1/4" NPT female, or 3/8" NPT female thread configurations
Compact 8" Body
Standard 8-inch length and 2.5-inch diameter fit tight spaces under sinks, inside RO housings, and in appliance installations
High Pressure Rating
Rated to 125 PSIG and 100°F, suitable for both municipal and well water systems with adequate safety margin for pressure spikes
Where to Use the Q5405
The Omnipure Q5405 filter is a direct replacement for Q-Series sediment cartridges in reverse osmosis systems, whole house filtration, under sink drinking water systems, ice makers, refrigerators, beverage dispensers, and drinking fountains. It requires an existing Q-Series filter head with 1/4" quick-connect or 1/4"/3/8" NPT female threads. This filter is part of the Q54xx series (8-inch Q-Series filters) and is compatible with any system designed for Omnipure's proprietary twist-off mounting system. Use as a sediment prefilter ahead of carbon stages or RO membranes to protect equipment and extend component life.
Omnipure manufactures Q-Series filters in the USA with consistent quality control, and the Q5405 is a proven sediment filter for residential and light commercial water treatment.
