Product Details

The 3Mâ„¢ Aqua-Pureâ„¢ Under Sink Reverse Osmosis Replacement Water Filter Cartridge AP5527 is a multi-stage reverse osmosis replacement water filter set of two cartridges that is for use with the NSF certified AP-RO55 reverse osmosis system.

Frequently Asked Questions

What is included in the 3M Aqua-Pure AP5527 Reverse Osmosis Filter Set?

The 3M Aqua-Pure AP5527 filter set is a complete replacement pack designed for the Aqua-Pure APRO5500 reverse osmosis system. It includes three essential filters: the AP5512 sediment pre-filter, the AP5522 carbon pre-filter, and the AP5521 carbon post-filter (polishing filter). This set covers all stages except the RO membrane itself, ensuring your Aqua-Pure APRO5500 continues delivering high-quality filtered drinking water.

What is the micron rating and filtration life of the AP5527 set?

The AP5527 set features a 5-micron sediment pre-filter (AP5512) that captures dirt, rust, and sand particles, along with carbon block pre- and post-filters rated at 5 microns to reduce chlorine taste, odor, and organic compounds. The recommended filtration life for the AP5527 pre- and post-filter set is 12 months or approximately 1,500 gallons under normal household use, whichever comes first. The RO membrane (sold separately) typically lasts 2 years.

Is the 3M Aqua-Pure AP5527 NSF/ANSI certified?

Yes, the Aqua-Pure AP5527 filter components are tested and certified by NSF International against NSF/ANSI Standard 42 for the reduction of chlorine taste and odor, and for material safety. When used as part of the complete APRO5500 RO system, the system is certified under NSF/ANSI Standard 58 for reverse osmosis performance, including reduction of total dissolved solids (TDS), lead, arsenic, fluoride, and other contaminants.

Which reverse osmosis system is the AP5527 compatible with?

The AP5527 filter set is specifically engineered for the 3M Aqua-Pure APRO5500 Under-Sink Reverse Osmosis Drinking Water System. It is not a universal RO set — the quick-connect fittings and filter housings are designed exclusively for the APRO5500 unit. Using the AP5527 ensures proper fitment, leak-free installation, and optimal performance from your Aqua-Pure RO system.

How do I replace the AP5527 filters in my Aqua-Pure APRO5500 system?

Replacement is straightforward thanks to the Aqua-Pure twist-off design. First, turn off the feed water valve and depressurize the system by opening the RO faucet. Twist each old filter cartridge (AP5512, AP5522, AP5521) counterclockwise to remove, then insert the new cartridge and twist clockwise until snug — no tools required. After installation, turn the water supply back on, flush the system by draining the RO storage tank 2–3 times, and your AP5527 set will deliver clean, great-tasting water immediately.
