Home Master: Under-Sink RO with Superior Remineralization Technology
Home Master (Perfect Water Technologies, Phoenix, Arizona) manufactures the TMAFC-ERP Artesian Full Contact ($350--$450), TMJRF2-ERP Junior F2 ($200--$280), and TMAFC Express Artesian ($280--$380) -- under-sink RO systems differentiated by their proprietary "Full Contact" remineralization technology that passes filtered water through two separate mineral-restoration stages rather than one. This dual-pass remineralization produces water with a more balanced mineral profile and a more neutral pH (7.0--7.5) compared to single-stage remineralization competitors like APEC ROES-PH75 or iSpring RCC7AK.
Home Master TMAFC-ERP: Full Contact Remineralization
Standard RO remineralization filters add calcium carbonate to one stage at the end of filtration. The Home Master Full Contact design passes water through a first calcite remineralization stage before the carbon post-filter, then through a second mineral stage after -- creating more contact time and more complete mineral dissolution. This results in consistent pH elevation to 7.2--7.5 (vs. 6.8--7.2 for typical single-stage remineralization) and more balanced calcium-to-magnesium ratios. For households who strongly dislike the taste of flat or slightly acidic RO water, the Home Master Full Contact is the most sophisticated remineralization solution in the under-$500 category.
Home Master vs. APEC vs. Waterdrop: The Remineralization Buyer's Guide
APEC ROES-PH75 (1-stage remineralization, $280--$360) vs. Home Master TMAFC-ERP (2-stage Full Contact, $350--$450) vs. Waterdrop G3P800 (post-carbon only, no remineralization, $350--$500): for households who specifically want remineralized water, Home Master's Full Contact provides the most complete solution. For households who primarily want low-waste tankless delivery, Waterdrop wins. For households who prioritize upfront cost, APEC wins.
