Under-Sink Water Filter Replacement Set for Aquasana 3-Stage Max Flow, 800-Gallon Cartridge Kit

Under-sink water filter replacement set restores three-stage Claryum filtration in compatible Aquasana Max Flow systems. Activated carbon and ultrafiltration media are WQA tested and certified for the listed reduction of up to 99.99% of 78 contaminants, including chlorine, lead, PFAS, and microplastics, while retaining naturally occurring calcium, potassium, and magnesium.

The Aquasana AQ-5300+R / AQ-C3M-R kit contains three polypropylene cartridges rated for six months or 800 gallons. It fits the listed AQ-6300M finish models and AQ-5300+.55, .56, and .62 systems. Replacement requires twisting off the housings, changing cartridges, and twisting them back on without disconnecting hoses. These filters do not reduce total dissolved solids. The listing also contains two-stage, three-stage, and finish-associated variants, so match the exact filtration system rather than selecting by color alone.
