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 | |
|---|---|---|
| Chlorine | Maker claim | Other systems for Chlorine |
| Chloramine | Maker claim | Other systems for Chloramine |
| Lead | Maker claim | Other systems for Lead |
| Fluoride | Maker claim | Other systems for Fluoride |
| VOCs | Maker claim | Other systems for VOCs |
| Sediment | Maker claim | Other systems for Sediment |
| PFAS | Maker claim | Other systems for PFAS |
No claim made for: Iron, Manganese, Hydrogen sulfide, Hardness, Bacteria, Arsenic, Nitrate, Copper, Uranium.
PFAS evidence: The maker's contaminant FAQ says 'Home Master RO systems are effective in reducing PFOAs'. Nothing backs it: no system listing and no published test data.

Home Master is made and sold by Perfect Water Technologies (theperfectwater.com, Phoenix AZ); homemasterfilters.com is the brand site. Both domains sit behind a Cloudflare challenge, so maker pages were read through the r.jina.ai reader (live, 2026-09-27) and a Wayback copy from 2026-07-18; both show $329.95. Cert finding: the page advertises 'NSF Certified Components' and says the ISetTMA8 filters are 'Certified to NSF standard 42 for chlorine reduction & Class V particulate reduction'. NSF lists Perfect Water only for 10 and 20 in cartridges that 'conform to the material requirements only' (not the TMAFC's inline filters) and for storage tanks under NSF/ANSI 58 for material and structural integrity (which tank ships with TMAFC is not stated). No system listing at NSF, IAPMO or WQA. Operating limits: 40-95 psi (35 psi with permeate pump), max TDS 2,000 ppm, max hardness 10 gpg, max iron 0.2 ppm, pH 4-10, max sediment 5 NTU. Options: permeate pump $89.95 (TMAFC-ERP), faucet finishes up to $42.50, larger tanks. No affiliate program found: only a customer referral scheme (50% off a filter set per referral); Amazon Associates applies to its Amazon listings. No recurring complaints found in fetchable sources: 30 on-site reviews all 5-star, Trustpilot has 1 review (unclaimed profile); Home Depot, Lowe's, Amazon and Reddit blocked fetches.
