necessary maintenance and priced right
I ordered the full set of 5 filters. The pre-filter and 2 big carbon filters were in a box, great. The membrane came in a heavy duty sealed bag, no box. Still OK. The FINAL in-line carbon filter was delivered as pictured. No bag, NOTHING! I thought it was a used customer return or something, but looks like others have experienced the same. The only thing to keep contaminants from getting into this in-line filter are the little soft rubber plugs. Hugely disappointed at the lack of cleanliness in this product's delivery. APEC can definitely do better here. At least with the membrane filter, I know its new and clean.

Can't beat the performance.
We love our APEC under counter water filtration R.O. system, enought to buy factory replacement consumables. Maybe a little more expensive than some of the aftermarket stuff, but probably better. Probably not the best place to skrimp, in my opinion.

Easy to install if you know how to extract...
I had a friend of mine install the water filtration system. When I want to replace the filters, I found these to be difficult. To begin, you need a special wrench from APEC to remove the cover. BE SUPER CAREFUL when removing the tubes... these break easily. DO NOT use a pincher. Use your hand. The filter works great and water flowers faster now.

OEM is worth the small premium
My Tap water TDS level is 450ppm before filtration. Post filtration it tests at 6ppm I replaced with an off brand Membrane after 4years of use only to see my TDS go to 37ppm. Replaced with an APEC and will never stray again.

Brought down my readings big time
My Reverse Osmosis system was giving me a very high reading. I kind of thought it was the Stage 4 causing the Issue. It solved the problem and am now back to very minimal readings. It was also a perfect fit into my system.
