I was happy to find these filters on Amazon. It’s half the price compared to APEC filters and work perfectly.

I replaced these first three filters on a 5 stage Apec reverse osmosis system. They were easy to install and after running through the purging cycle I tested my water with a TDS meter and it measured 14 ppm like the original filters. So they're doing their job.

These filters don't remove impurities as well as the APEC filters. They may be ok as pre-filters for RO system. I have replaced original filters with these in my APEC WFS 1000 and can now taste unpleasant tap water flavor

These replacement pre filters fit perfectly in my APEC. PH75.

good quality's

We have used these filters for years and find the manufacture is great. Works well to provide clean clear water.

I replaced my Aro system filters after one year of installing it. The first filter was very dirty but the other two carbon filters were not. I am very glad that I replaced them.

I order these every year, and the product is perfect. You should replace the o-ring seals on the filter cartridge housing every time; I didn't and I had a serious leak develop, so make sure to replace those seals and clean the seal surfaces when you install them.
