All US Made Super High Capacity Filters

1st Stage: High-Grade 5 micron 10" high-capacity polypropylene sediment filter -removes dust, particles, and rust. 100% pure polypropylene depth filter with exceptional dirt-holding capacity translates to longer life and fewer change-outs than existing string-wound or resin-bonded filters. Recommend changing every 1 year.

2nd and 3rd Stage: Premium Extruded Carbon Block 10" -gets rid of unpleasant chlorine, tastes, odors, cloudiness and colors. Also removes VOCs and other common chemicals from the water. APEC's extruded carbon block filters consist of activated carbon particles fused into a uniform block with enhanced adsorptive capacity and efficiency. Unlike granular activated carbon (GAC) filters, these extruded carbon block cartridges will not channel or bypass due to the extreme uniformity of their extruded activated carbon core. Recommend changing every 1 year.

6th Stage: 100% US-Made high purity 10" inline calcium carbonate to effectively neutralize acidity. Recommend changing every 6-12 months.

pH Filter

The FI-PHPLUS-QC is a 10" inline filter that adds high purity food grade calcium minerals to enhance the water taste for people who prefer drinking mineral water. This mineral cartridge adds only 100% US-made high-purity calcium carbonate to effectively neutralize acidity and raise pH in the water. Other re-mineralization filter will claim to add various beneficial minerals back into the water; however, their mineral formulations are often from unknown sources.

For over 20 years, APEC has been an industry leading manufacturer of high performance RO systems.
