5-Stage Replacement Cartridge Breakdown
A standard 5-stage replacement set (such as those compatible with models like the ABS5144) includes five distinct filters:
โข 10โ PP (Polypropylene) Cartridge Filter: Traps larger physical debris, sand, rust, and silt.
โข 10โ UDF Carbon Cartridge Filter: Absorbs chlorine, odors, and organic compounds.
โข Carbon Block Cartridge Filter: Provides secondary chemical and fine sediment reduction.
โข UF Membrane Cartridge Filter: Uses hollow-fiber ultrafiltration (typically ~0.2 ยตm pore size) to block bacteria, germs, and suspended colloids while letting clean water pass through.
โข Post Carbon Cartridge Filter: Polishes the final taste and odor of the water.
