Not included because the maker does not sell or price them separately: Pre/post-filter housings (not sold online; replaced through Aquasana Customer Support, price not published). The real 10-year cost will be higher.

Install assumption: $500 for whole-house systems, $150 for under-sink units. Installing it yourself brings the total to $3,764. Try your own numbers in the 10-year cost calculator.

Owner reports

On-site reviews (13, avg 3.8/5), Rhino-plus-conditioner bundle reviews and Trustpilot repeatedly report that scale spots and hard-water buildup continue (buyers expected softening) and some report a noticeable pressure drop.

Trustpilot: 1.5 from 172 reviews (source).

Standalone sale $879, MSRP $1,758. All prices are the site-wide '50% OFF + FREE LOW MAINTENANCE PRE-FILTER, Limited Time Only!' sale price; the MSRP shown is exactly 2x the sale price on every system and replacement tank checked, so treat the sale price as the real price. The page still says it pairs with 'Rhino 600,000 Gallons, and the OptimH2O systems', both discontinued (the OptimH2O whole-house URL now redirects to the category page). annualCostUsd = pre/post filters + tank amortized over 10 years at sale prices. On-site rating 4.4/5.
