Best water
"I’ve been using their RO filters for over 20 years. Everyone that drinks water at my house always says”is this tap water” no, it’s RO."


APEC Ultimate high flow 6-stage complete filter set is made in USA with the highest quality filtration components to provide a longer lasting filter set to protect and prolong the lifespan of your reverse osmosis system. Premium quality pre-filter cartridges lasts over 12 months while the membrane and post carbon filter last 3-5 years for fewer filter change outs and high performance contaminant removal. These standard size filters are compatible with APEC RO-PH90.
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. Recommend changing every 1 year.
2nd and 3rd Stage: Premium Extruded Carbon Block10 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. Recommend changing every 1 year.
4th Stage: Select FILMTEC (Dow Chemical) High Rejection TFC reverse osmosis membrane. Removes up to 99% of total dissolved solids (TDS) and contaminants such as arsenic, lead, fluoride, chromium, radium, bacteria, viruses and much more. Recommend changing every 3-5 years.
5th Stage: Advanced 3/8" Quick Connection Coconut Shell Refining Carbon 10 Inch - TCR (Total Contamination Removal) filter removes any possible residual taste from the tank. Recommend changing every 3-5 years.
6th Stage: 10 Inch High Purity pHPlus Calcium Carbonate Re-mineralization Inline Filters w/ Quick Connect-increases pH level of the water by adding calcium carbonate mineral back into the water. Recommend changing every 6-12 months.
For over 20 years, APEC has been an industry leading manufacturer of high performance RO systems.

"I’ve been using their RO filters for over 20 years. Everyone that drinks water at my house always says”is this tap water” no, it’s RO."
"See what happens over the next year. How may I tell when to change the filters other than by time?"
"Easy to assemble, make sure you get the right tubing size as I made that mistake."
"Ordering the filters were a breeze. Good customer support that made ordering easy. To my surprise, the filters I ordered had not changed in price for 2 years."
"THANK YOU EVERYTHING WORKED1"
"Great product with superior customer service"
"I've had a RO-PERM system installed since 2017 and change all the filters annually to keep the water tasting great. Installed another RO-PERM at my parents house in 2019. This filter set takes the guesswork out of ordering them separately. Everything comes packaged neatly and replacement time is minimal."
"I've had this system for 6 years now. While I've never done a test to see exactly what it's filtering the taste is great and the system has performed flawlessly over all these years. I don't detect any chlorine or other tastes present in the tap water the water is clear and I can taste the added minerals. In addition the water flow has always been excellent. I bought the upgraded 3/8 outlet lines. I love the system. I just recommended it to another friend who I hope buys this system as well."
"New filters got the TDS readings down and the pH cartridge got the great taste back."
"Only once every five years for the complete system makes it economical and a breeze to maintain."
