What it treats
"Certified" means an independent body (NSF, IAPMO, WQA or CSA) lists this system for that contaminant. "Lab tested" means the maker published a third-party lab report. "Maker claim" means neither.
| Contaminant | Evidence | |
|---|---|---|
| Hardness | Maker claim | Other systems for Hardness |
| Sediment | Maker claim | Other systems for Sediment |
No claim made for: Chlorine, Chloramine, PFAS, Lead, Iron, Manganese, Hydrogen sulfide, Bacteria, VOCs, Arsenic, Nitrate, Fluoride, Copper, Uranium.
PFAS evidence: No PFAS claim (scale conditioner). The page still shows the unrelated Claryum '78 contaminants' list incl. PFOA & PFOS.

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.
