APEC FILTER-MAX-ES50 50 GPD High Capacity Complete Replacement Filter Set For Essence Series Reverse Osmosis Water Filter System

Great product over the years, great water and unit. Filters did not scare me much, always concerned about o-rings and leaks, but the filters never leaked. The whole unit was a bit scary this first time with all the hoses disconnected and worri3ed that they'd keak afte re-attaching. Take a pic of all couplings, Remember to push-in to release existing hoses. Everything went back and did not leak. Iam back to great water for 3e years! Thanks APEC Ted

I own several APEC water filtration systems and have had them for about 6 years. Their replacement filters are consistent, well made and durable. My orders come in a timely manner and are reasonably priced. I respect this product and would hope that everyone who buys water from plastic bottles would consider this as an alternative approach. Great tasting and convenient.

Their water system is phenomenal, my friends come over to take my water all the time! I installed the RO system 3 years ago, the instructions were well written, concise and the job was made super easy. Changing the filters, same deal, they come with concise instructions and the process is a breeze. I seldom write reviews but this company deserves a mention and their 5 stars...

APEC's Essence ROES-50 system has been working well since first purchased several years ago, but it was time to replace all the filters (as we also have a whole house filtration system, we stretched this task out for the under-sink RO unit from the standard recommendation). The filters came well packaged, with instructions as reprinted from the user manual (small discrepancy, instructions stated that a new "tee" connection was also sent, but this was not the case; not a big deal since the original one was easily re-used). It was a bit intimidating to this lay plumber, but once I stopped the procrastinating it was a straightforward project (I was also hesitant given a professional plumber had just fixed a leak to the faucet, evidently the fault of the original installation squeezing the O-ring too tight so it eventually failed, causing a cabinet-damaging leak, but again not the fault of APEC). Having learned about the quick-connect tubing methodology, and taking care in the disassembly and re-assembly of the various filter units, I had no leaks and all worked as expected. After a deeper read of the user instructions, I plan to obtain the recommended TDS (total dissolved solids) meter, an inexpensive tool to be able to more precisely determine effectivity of the RO filter system and timing for future filter replacements. Included tools were also helpful.

I bought this set of filters with new RO element to replace a set I recently install in my system. I did not replace the RO element, only the filters. After replacing the filters, the system is currently operating at a 95% rejection rate. Very pleased with overall performance of the system.

We've used the APEC water filtration system in our home for several years now and could not be happier with it. Our water now tastes amazing, and exchanging the filters is not complicated. I'd recommend APEC water filters to anyone looking for great value and high performance.

We've had the ROES-50 system for several years and love having clean, clear and great tasting water. We liked ours so much we bought a second unit for our daughter's house. One thing I love is being able to order complete filter replacement kits for either routine or complete change overs.

I've had the 5 stage ro since March I had it I nstalled by handyman. I forced myself to change filters and clean. I'm not afraid of it anymore. I enjoy the water and added mineral filter. I hooked up tubes to ice maker. I'm a brave 71year old Retired soldier :)

Replace stage 1 filter once a year to keep system running smoothly.

Purchased a house with this system in it. Attempted to install new filters. I ended up playing “wack a mole” with all the tubes coming undone and getting water everywhere. After I finally got it all put together, I now have little white specks in the water. Not sure if that's good or not....but the whole experience has left me wanting to put the system into the fire pit.
