Review on AppliaFit Reverse Osmosis Compatible Version by Patricia Pena

It was a pleasant purchase. Our reverse osmosis system is a few years old and one of the chambers recently started leaking a bit after replacing all the filters. I measured the width of our o-rings and decided to take a chance. They work great! They stopped a leak in our leaky filter and even gave them to my father-in-law who was able to use them too after measuring his reverse osmosis o-rings. The cost is high compared to the competition and they hold up great after a few months. To what extent they differ qualitatively from the original, we cannot say. I will update if anything changes but so far very happy with this purchase.
