## Description

APEC 50 GPD Essence reverse osmosis membrane is an effective filtration element that has been designed to deliver high impurity rejection rates at high input TDS levels.

It will fit in most commonly available housings to provide ultra pure and safe reverse osmosis drinking water.

Review: 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.
Review: Easy to install, great water quality - 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.

### ⭐⭐⭐⭐⭐ OEM is worth the small premium
*by W***. on November 24, 2025*

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.
