Aquasana: NSF-Certified Filtration Across Whole-Home, Under-Sink, and Shower
Aquasana (Austin, Texas, owned by A.O. Smith since 2016) occupies the premium segment of the residential water filter market with NSF-certified systems at multiple price points: the EQ-1000 whole-home filter ($800--$1,400), the OptimH2O under-sink RO ($300--$400), the Clean Water Machine pitcher ($80--$120), and the shower filter line ($30--$90). Aquasana's strength is comprehensive NSF certification scope -- the EQ-1000 is certified to NSF 42, 53, and 401 (emerging contaminants), making it one of the most broadly certified whole-home filters on the market.

Aquasana OptimH2O vs. APEC ROES-50
Aquasana OptimH2O ($300--$400) vs. APEC ROES-50 ($200--$260): Aquasana provides broader NSF certification including NSF 401 (emerging contaminants: PFAS, pharmaceuticals, pesticides). APEC provides comparable core RO performance at lower upfront cost. Annual filter replacement costs are higher for Aquasana ($80--$120/yr) vs. APEC ($50--$75/yr). For households whose primary concern is emerging contaminants and NSF 401 documentation, Aquasana is the premium choice. For households prioritizing upfront price and established NSF 42/53 performance, APEC is the better value.
