Bought this set in exchange for a long time but it doesn't seem to filter properly, I got 44-62ppm like old filters even though they were 6 months old 10-20 parts per million. I do not know if the quality. Too bad it's probably impossible to return or exchange them as I installed a set of filters out of the box.
