AP3K - Replacement Filter Kit for 3 Stage Reverse Osmosis
The AP3K Replacement Filter Kit from AMPAC USA maintains the performance of your 3-stage reverse osmosis system, extending its lifespan and ensuring a continuous supply of clean, great-tasting water. Regular filter replacement with the AP3K protects the more expensive RO membrane from premature wear, and the kit packages the components needed for annual filter service in one place.
- CTO/2 Extruded Carbon Block Pre-Filter, 5-micron rating, removes sediment and reduces chlorine, taste, and odor
- GAC Granular Activated Coconut Shell Carbon Post-Filter, polishes water before it reaches the faucet
- Compatible with AMPAC USA 3-stage under-counter RO systems and other 3-stage systems using standard 10-inch filter housings
The AP3K is engineered for AMPAC USA 3-stage under-counter reverse osmosis systems and is also compatible with other 3-stage RO systems that use standard 10-inch filter housings. The two filters work together: the CTO/2 pre-filter removes sediment and reduces chlorine, taste, and odor, protecting the later filters and the RO membrane from larger impurities.
The GAC post-filter, made from coconut shell carbon, refines the permeate water before it reaches the faucet, removing residual dissolved gases or organic compounds that could affect taste or odor. Together, the pre-filter and post-filter form an effective pre-treatment and post-treatment system that supports the performance and longevity of the RO membrane.
The AP3K suits residential kitchens, small offices, and any setting with a 3-stage under-counter RO system. Regular replacement is essential for keeping the system operating at peak efficiency and continuing to deliver the pure water it is designed to provide, and each filter is produced under AMPAC USA's quality control standards using high-grade materials.
