Owner reports

Brand-level: Trustpilot reviews of Quality Water Treatment (3.3/5, 29) and SoftPro Water Systems (3.7/5, 18) repeatedly cite slow or no post-sale support, shipping delays and missing parts, and returns or warranty claims held up by mandatory troubleshooting. Product-level: several on-site Iron Master reviews report the tank arriving on its side with the riser tube pulled out of place, and missing fittings.

Trustpilot: 3.3 from 29 reviews (source).

Same prices on qualitywatertreatment.com and softprowatersystems.com ($1,517 / $1,757 / $1,897); compare-at prices differ by site ($2,300.55-$2,820.65 on QWT vs $2,036.50-$2,494.50 on SoftPro). Shopify vendor field is Canature Water Group. Maker claims iron up to 30 ppm without added oxidizers, manganese up to 7 ppm, H2S up to 5 ppm, and 'arsenic removal up to 120 ppb (additional requirements needed)'; 'Laboratory Tested & Approved!' is stated but no lab report is published, so all claims stay 'claimed'. Cert finding: the SoftPro product page shows an 'NSF / WQA / ANSI Certified' badge, but NSF DWTU has no SoftPro, Quality Water Treatment or Iron Master listing (Canature's NSF listings are cartridges, housings and softener components), WQA's product search returns nothing for SoftPro, Canature, Quality Water Treatment or Iron Master, and Katalox Light is not among Watch Water's WQA NSF 61 listings. Install guide: 30-125 psi (70 psi max recommended), 40-110 F, 120 V outlet, typical install 4 h DIY or 3 h for a plumber; product page says suitable for experienced DIY homeowners. Many reviews in the QWT on-site widget are templated one-liners containing the product handle and describing 'soft water' (this is an iron filter), so on-site ratings look polluted by spam.
