Replacement Filter Set for ULTIMATE Series Alkaline Reverse Osmosis Water System

The APEC Ultimate high capacity pre-filter set, manufactured in the USA with premium quality filtration components, is designed to provide longer-lasting protection and extend the lifespan of your reverse osmosis system. This pre-filter set is a bundled solution consisting of Stages 1-3 and Stage 6, ensuring comprehensive water purification.

Featuring an impressive 12-month filter life, this pre-filter set reduces the frequency of filter changes, offering high-performance impurity removal for your convenience. The filters are compatible with the APEC RO-PH90 and all other 10-inch standard size under-counter RO systems.

The 1st stage of the set is a high-grade 5-micron 10-inch polypropylene sediment filter, which effectively removes dirt, particles, and rust from the water. This 100% pure polypropylene depth filter boasts exceptional dirt-holding capacity, resulting in a longer lifespan and fewer change-outs compared to traditional string-wound or resin-bonded filters.

The 2nd and 3rd stages consist of premium extruded carbon block 10-inch filters, designed to eliminate unpleasant chlorine, tastes, odors, cloudiness, and colors. These filters also remove volatile organic compounds (VOCs) and other common impurities. APEC's extruded carbon block filters are made with activated carbon particles fused into a uniform block, providing enhanced absorptive capacity and efficiency. Unlike granular activated carbon (GAC) filters, these cartridges are less prone to channeling or bypassing due to the exceptional uniformity of the extruded activated carbon core.

The 6th stage of the pre-filter set features a 100% USA-made high-purity 10-inch inline calcium carbonate filter, the FI-PHPLUS-QC, which effectively neutralizes acidity and raises the pH of the water. This mineral cartridge adds only 100% USA-made high-purity calcium carbonate, unlike other re-mineralization filters that may use unknown mineral sources.

Compared to other brands, the APEC ULTIMATE Series high capacity pre-filter set is designed and manufactured in the USA, built to last twice as long. Included in the set are (1) sediment filter, (2) carbon block filters, and (1) FI-PHPLUS-QC Alkaline Calcite Filter, making it a complete solution for use with the APEC RO-PH90 or any other systems with a pH enhancer kit upgrade.
