Home Master Replacement Filter Sets
Home Master sells replacement filter sets by system: the TMAFC-ERP replacement set (TMFHFL, $75--$100) includes the pre-filters and post-mineral stages but excludes the RO membrane (replace every 3--5 years, separately). Annual maintenance cost at 2,000-gallon intervals: $75--$100 per filter change, occurring approximately once every 16 months for a 4-person household. Total annual cost: approximately $55--$75 -- competitive with or better than APEC and iSpring annual filter costs despite the more comprehensive filtration stages. Home Master replacement filters are available directly at perfectwatertech.com and through Amazon. Third-party filters that fit Home Master housings exist but may not meet OEM specifications -- Home Master warranty requires OEM filter use.
