Aquasana

Aquasana is a water filtration brand covering whole-house systems, reverse osmosis, under-sink, countertop, and shower filters. Its flagship Rhino whole-house line uses an upflow dual-tank design with carbon and KDF media, independently tested to NSF/ANSI Standard 42 for chlorine reduction, with capacities ranging from 600,000 to 1,000,000 gallons. Chloramines and Max Flow variants handle treated municipal water and larger homes, while the well-water systems add UV sterilization.
