Atlas ra5706511 Water Filter Cartridge 25 Microns

Product Description

The ATLAS ra5706511 is a 4.5 x 10 inch polypropylene melt-blown water filter cartridge rated at 25 microns. It is engineered for consistent sediment reduction across residential, commercial, and light industrial water systems. The graded-density melt-blown polypropylene construction captures particles throughout the full depth of the media, not just at the surface, resulting in high dirt-holding capacity and a longer service life compared to surface-only filter media. Plumbers and water treatment technicians install this cartridge in standard big-blue style housings to protect downstream equipment such as water heaters, fixtures, and process equipment from sediment fouling.

This cartridge is suited for whole-house sediment pre-filtration, point-of-entry commercial water systems, and light industrial process lines where particulate control at 25 microns is required. Its melt-blown polypropylene construction makes it compatible with most cold and moderately warm water supply lines. It is commonly installed upstream of softeners, carbon filters, reverse osmosis systems, and other treatment stages where influent sediment load would otherwise reduce the performance and service life of downstream media.

Key Features

• 25-micron rated filtration removes fine sediment, silt, rust particles, and suspended solids
• Graded-density melt-blown polypropylene construction maximizes dirt-holding capacity and extends change intervals
• 4.5 x 10 inch form factor fits standard big-blue filter housings
• Polypropylene media is chemically compatible with most potable water and light process water applications
• No binders or adhesives in the media matrix, reducing risk of media migration into the water stream

Compatibility

Designed as an OEM-style replacement cartridge for standard 4.5 x 10 inch big-blue style filter housings used in residential, commercial, and light industrial water filtration systems.

Installation Notes

A licensed plumber or qualified water treatment technician should perform cartridge replacement. Shut off the supply valve and relieve system pressure before opening the filter housing. Use a housing wrench to remove the sump and inspect the O-ring for wear or cracking before reinstalling. Follow local plumbing codes and the housing manufacturer's torque guidance when reassembling the sump to prevent leaks.
