APEC RO Replacement Filters Complete Filter Set for ULTIMATE RO-90 and RO-PERM Models With 1/4"D Tubing (Stages 1-5)

Safe Drinking and cooking water

We get our water from a deep well. Nevertheless, we feel safer having a APEC RO system under out kitchen sink. Inexpensive, and easy to maintain filter changes. Hookups are a snap, off and on with no leaking. I recommend APEC RO. My daughters have one and my sister recommended I should have an APEC RO.

Good Value for Full Filter/Membrane Replacement

We have had our APEC RO system for 4 years and I changed out all of the filters and the membrane when our flow dropped off. Very easy swap on all 5 elements and a good price when purchased as a kit. The filter/membrane swap did not help our flow, so the membrane probably would last 5+ years in our application. We have a 10 micron filter on our main water line and a water softener, so our system sees reasonably good water. The root cause of our flow problem was the pressure tank had lost its air pre-charge. I purged all of the water out of the pressure tank, charged it with about 6 psi of air, and let the system re-fill. Our RO water pressure and flow is as good or better than new now.

Pure water, reasonable cost

We enjoy having the convenience of the RO 90 system giving us pure water without the hassle of buying bottled water. It also provides pure water for our refrigerator ice maker. I believe it gives us a savings of not having to buy bottled water. We are very satisfied with the system.
