General RO Filter Installation Video
APEC Ultimate high capacity pre-filter set is made in USA with high quality filtration components to provide a longer lasting filter set to protect and prolong the lifespan of your reverse osmosis system. Premium quality filter set lasts over 12 months for fewer filter change outs and high performance contaminant removal. These standard size filters are compatible with APEC RO-45, RO-90, RO-PH90, RO-PERM, RO-PUMP, RO-Hi, WFS-1000 and all other 10 Inch standard size under counter reverse osmosis systems.
1st Stage: High-Grade 5 micron 10 Inch high-capacity polypropylene sediment filter -removes dust, particles, and rust. 100% pure polypropylene depth filter with exceptional dirt-holding capacity translates to longer life and fewer change-outs than existing string-wound or resin-bonded filters.
2nd and 3rd Stage: Premium Extruded Carbon Block 10 Inch -gets rid of unpleasant chlorine, tastes, odors, cloudiness and colors. Also removes VOCs and other common chemicals from the water. APEC's extruded carbon block filters consist of activated carbon particles fused into a uniform block with enhanced adsorptive capacity and efficiency. Unlike granular activated carbon (GAC) filters, these extruded carbon block cartridges will not channel or bypass due to the extreme uniformity of their extruded activated carbon core.
For over 20 years, APEC has been an industry leading manufacturer of high performance RO systems.

"I purchased my filter system in March of 2025. Very happy with the overall quality of the unit and faucet dispenser. Recently subscribed to the 12 month filter replacement program. The instructions are straight forward, easy to follow and simple to replace the cartridges. So far, so good!"
"These filters are fairly easy to install, with minimal effort. The quality of the filtered water is vastly better than the tap water in Cincinnati. We are very happy with the results."
"Wanted an American made filtration system for my drinking water and APEC delivered. I love that when you order direct from APEC you can order the o-rings and lubricant right there."
"I have been ordering filters for my RO-90 for more than 20 years and the unit has been delivering clean water for that whole time. I change filters 1,2,3 every year and 4 and 5 every 5 years or so,"
"I ordered a 5 and a3 stage filter replacement. I wrote a review for the 5 stage I won’t be using the 3 stage until next year!!!!! So I won’t be writing a review till then. Thanks for your concern."

"These filters are excellent. John A in customer service was very to straighten out our problem because we didn't follow the instructions that were included. He sent a color schematic and told us what we did wrong and how to connect it properly. Easy to fix and works great now."
