> 3 dayThe middle filter does not work in my standard housing. It lets littlw to no water get by and had me chasing my tail trying to figure out why I would loose all pressure. Will never buy this set again

10-06-2025Great price. The blue top carbon filter (2nd stage) top hole was too small for my system though. I have a standard 5 stage i-spring system, and the standard housing bits seem to take a ~1 1/16 filter hole. The hole in the blue housing was only abut 15/16. I had to drill it out with a forstener bit, and then it fit fine.
