## Description

APEC Water Ultimate high flow 5-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. Compatible for APEC Water RO-45, RP-PUMP, and all other standard size under counter 20-50 GPD ro systems on the market. 1st stage: high-grade 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 Water'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. 4th stage: high rejection 50 GPD TFC reverse osmosis membrane. Removes a wide variety of contaminants including arsenic, chlorine, lead, fluoride, chromium, radium and more. 5th stage: advanced coconut shell refining carbon 10 inch - TCR (total contamination removal) filter removes any possible residual taste from the tank.

Review: Oh Yeah! - Tough to get excited about a filter pack, but this one might do it. It just plain fit perfectly and worked immediately. I bought the system new in 2012 and hadn't touched a darn thing since and we use a gallon a day. So I just got the whole package. Delivered promptly. Then....discovered everything fit but to install the last final filter, APEC had upgraded a fitting and it wasn't included. I called and the guy promptly said no problem, fitting would be sent immediately, no charge. Darned if it didn't arrive in a couple of days and everything fit. So: good product, all fits, works great, excellent customer service and rational price. In goes our salty, sulphuric high dissolved solid water and out comes clean, nice tasting water. The whole unit just sits there and does it's thing. I think that's how it should be and APEC makes it so. Yeah, five stars.
Review: Great system, great supplies - Love this RO system, supplies are relatively affordable and they last. No issues - just great water.
