APEC ROES-PH75

For a small bar pulling under 50 shots a day, the APEC ROES-PH75 at well under $400 with built-in alkaline remineralization is the lowest-cost path to in-spec water. You do not even need to source a separate post-filter. For anything beyond that volume, the iSpring RCB3P at around $500 is the most cost-effective light-commercial option, and you add a $30 inline calcium cartridge to finish the water profile.

To say the APEC Water Systems ROES-PH75 is the best under sink water filter system is an understatement. Boasting a whopping 6-stage filtration system, supreme quality design, manufacturing, and assembly, APEC can deliver 75 gallons per day (GPD), removes up to 99% of contaminants, and is compatible with water pressures between 40-85 pounds per square inch (PSI). All of this equates to the purest, freshest, filtered water.

If your cold-water supply at the sink is modern and pressure tests above 50 PSI, you don't need a pump and the APEC ROES-PH75 is a better long-term value than a pumped system (no electrical, fewer failure points). The six-stage build adds calcium and magnesium back for taste, which matters when you're going from "old pipe water" to RO — the contrast in mouthfeel without remineralization can be jarring.

Overall I think this Apec Water Systems Reverse Osmosis is a fantastic product and I highly recommend it!

This is a APEC roes ph75 and this system is awesome I'm very very happy to have this, it's been great.

Performed excellently in our contaminant reduction testing

This wonderful system works perfect, we don't have to run out to get bottle of water anymore if we want cold or hop water we just fill out our 5 gallon big bottle water to connect it to the water dispenser that is all. You also can safe a lot of money.

Buying this system is a win any way you look at it.

It is trouble free, great exhibit performance and also comes with a warranty. It is a must recommend indeed!
