Aquasana Rhino WH-1000 review
Aquasana Rhino Whole House Water Filter System (WH-1000, 1,000,000 gallons, bundle)
By Tom Calder
A big carbon and KDF tank rated for a million gallons or ten years, with a pre-filter. Its certifications cover the tank's materials (NSF/ANSI 61 and 372 via WQA), not what it removes: Aquasana's chlorine figure is independently tested, not certified, and its long contaminant list on the product page isn't backed by a certifier's listing.
- Best for
- A 10-year carbon tank for city water
- Skip it if
- You want a certified chlorine claim
