Frequently Asked Questions
Is Home Master worth the extra money?If you value the larger fittings (better flow), modular design (easier changes), and 5-year warranty, yes. If you just want reliable RO water at the lowest cost, APEC is the better value.
Can I add UV to an APEC system later?APEC doesn't offer UV add-ons directly. You'd need to install a separate UV sterilizer after the RO system, which is possible but adds complexity.
Which has better water waste ratio?Both are similar at approximately 3:1 (3 gallons waste per 1 gallon produced) without a permeate pump. Home Master offers permeate pump models that improve this to 1:1.
Are Home Master filters proprietary?Yes — the modular design uses Home Master-specific cartridges. APEC uses more standard sizing, making third-party filter compatibility easier.
