Was looking for a replacement for my stage 3 for the 4 filter system and was happy to find out that the stage 2 in the 3 part system fits… cause it’s impossible to find the stage 3 since the company went out of business

Must have received an old filter since the ppm of our water went up 50 points after putting this in. I am told by the company that these filters decay while in storage.With our original Reverse osmosis filter and other 4 filters from PureBlueH2O our water reading was 21 ppm (which is excellent! ) After a year it went up to 56 and then each month more, so we changed out for new and the reading went up to 156! Needless to say, very disappointed. Otherwise, I would have rated this 5 star. Sigh.
