APEC Water MEM-ES-50 Membrane Replacement Filter, 50 GPD | For Reverse Osmosis System, 1 Count, High Contaminant Rejection, Industry Standard Sized Membrane

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 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.

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.

The water quality from this system is great and we don't need bottled water for drinking or ice. It lasted over 4 years based on readings from my TDS meter and probably would have gone longer.

Shipped in good time and easy to install

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.

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.

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.

Worked as advertised.
