Product Description The Claryum® 2-Stage Filter Replacements set is designed for use with the Aquasana Claryum® 2-Stage systems (models AQ-6200-BN, AQ-6200-CHR, AQ-6200-ORB, AQ-6200-MB, AQ-6200-NF, AQ-5200.55, AQ-5200.56, AQ-5200.62) and provides clean, great-tasting water for up to 6 months or 500 gallons. The AQ-C2-R is the new replacement filter for systems that used the AQ-5200R. This set includes two powerful Claryum® filters that combine activated and catalytic carbon with ion-exchange, sub-micron filtration, and an organic adsorbent booster for premium, highly effective water filtration. These replacement filters now feature even better contaminant reduction. Aquasana's Claryum® filtration technology is tested and certified to NSF/ANSI Standards 42, 53 (includes P473), and 401, for the reduction of 99.995% of Cysts, 99.6% of microplastics and lead, 99.7% of PFAS Forever Chemicals (specifically PFOA/PFOS), 97.3% of chlorine, and 91% of chloramines. The PFOA/PFOS results are tested down to 20 parts per trillion (PPT) per NSF’s new, even more stringent testing protocol. The Claryum® 2-Stage is also certified to tackle mercury, herbicides, pesticides, pharmaceuticals, and more — 15x more contaminants than the leading pitcher filter. Claryum®’s selective filtration retains healthy, naturally occurring minerals like calcium, potassium, and magnesium — so your water tastes better and supports overall wellness. Designed with sustainability in mind, these replacement filters minimize disposable plastic waste — reducing your environmental footprint with every use. Each set lasts up to 500 gallons, replacing over 3,750 plastic water bottles at less than a tenth of the cost. Choose a smarter, eco-friendly solution that makes a real difference. And with our twist-off design, filter replacement is quick and tool-free — no hoses or water lines to disconnect. The set also includes a replacement battery so the system can alert you when it’s time to change filters.
