   El filtro es exactamente lo que buscaba, y funciona perfectamente bien. Lo compraría de nuevo con el mismo proveedor. Nos llego en 12 días con envío gratis.

   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.

   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.

   I LOVE our APEC RO system. The water tastes absolutely pure, bottled water tastes like plastic, tap water tastes like chlorine. This tastes like nothing, as it should. Every time we get we see a warning about lead pipes or other contamination in the water I’m glad we have this. Changing the pre filters every year and the ro filter every 2 years is no big deal. Even cleaning all the parts fastidiously, it only takes an hour or so to do a full filter change.

   It does waste 5 gallons of water for every 1 purified. I’ve checked. But imo for drinking water that’s no big deal. If your family drinks 1 gallon of water per day that’s only 1 extra toilet flush. It’s certainly far for environmentally friendly than buying bottled water.

   Installation of the system is fairly easy for a handyman.

   Not sure if it is a Hydron or Filmtech filter but my previous membrane that came with my APEC system was Hydron and only lasted 18 months. After installing the new one my RO water TDS went from 400 to 80. The source water is 1500 TDS so the reject rate is very good on this membrane. The membrane housing was on way too tight from the factory. I had to remove the housing and put it in my vice to unscrew the gap with an 18″ pipe wrench. APEC also does not include replacement O-rings for the membrane housing. Why the heck not for what they are charging? Minus one star for no eeplacement housing O-rings (see photos).

   Do change your membrane according to the schedule, specially if your area is high in chlorine. Order both filters at the same time, it’s easy and fast to do. The system tastes and tests like new again! The cost is really not that much, no reason to postpone doing it. It’s now on the schedule for regular replacement.

   Worked as advertised.

    I was glad to find the right membrane, and it worked great for about a month and a half. Now it’s already stopping water flow almost completely. Not sure if I’ll have to just rebuy another one or if I can find one that works better, so time to do some research.

    Just be aware, this one might not last long if you choose to go this route.

    UPDATE: Company reached out to me and had me run a few tests on the system… then sent me a new membrane when we realized something must be wrong with the one I bought. Good customer service and I appreciate them making it right.
