10" High Pressure Filter Housing QMP300W
Reinforced polypropylene housing for standard 10" x 2.5" cartridges with 1/4" NPT ports, rated to 125 PSI and 125°F
Built for demanding applications where standard housings fail
High Pressure Rated
Tested beyond industry standards to 125 PSI, this QMP300W housing handles municipal and well water pressure without bulging or failure
Chemical Resistant Build
Reinforced polypropylene construction resists chlorine, acids, and common water treatment chemicals without degradation
Standard 1/4" NPT Threads
Quarter-inch NPT ports provide secure connections for common push-fit and threaded fittings in under-counter and point-of-use systems
Temperature Tolerant
Rated to 125°F, the QMP300W handles hot water applications and temperature fluctuations in commercial and industrial settings
Universal Cartridge Fit
Accepts all standard 10" x 2.5" cartridges including sediment, carbon block, pleated polyester, and specialty filter media
Works with all standard 10-inch cartridges
The QMP300W fits any 10" x 2.5" diameter filter cartridge including sediment filters (1, 5, 10, 20, 50 micron), carbon block cartridges, granular activated carbon (GAC), pleated polyester, string wound, melt-blown polypropylene, and specialty media like KDF, catalytic carbon, or bone char. Compatible with brands including Pentek, Hydronix, Matrikx, Filtrex, Aquaboon, and generic standard cartridges.
Filter replacement schedule by cartridge type
Sediment Filters
Replace 5-10 micron sediment cartridges every 3-6 months depending on dirt load and pressure drop. Heavy sediment may require monthly changes.
Carbon Block
Carbon block cartridges lose chlorine removal capacity over time. Replace every 6-12 months or when taste and odor return.
GAC Cartridges
Granular activated carbon filters should be changed every 6-12 months to maintain chemical reduction performance.
Housing O-Ring
Inspect the sump o-ring each time you change cartridges. Replace if cracked, flattened, or leaking. Lubricate with silicone grease during reinstallation.
Under-Counter Ready
Compact 10-inch size fits in tight spaces beneath sinks and in mechanical rooms
Commercial Grade
Reinforced construction handles continuous flow in restaurants, offices, and light industrial uses
Pressure Tested
Every QMP housing is tested beyond rated pressure to ensure reliability and safety
Reusable Design
Replace cartridges, not the entire housing, reducing plastic waste and long-term cost
