Review on Aq 5300R 3 Stage Counter Replacement Cartridges by Alex Jones

Easy to install like Aquasana filters. However, when I first turned on the water, the system made a loud groan and the water flow stopped. The airlock problem was solved by removing the seals from the black Aquasana filter and putting them on the new filter. stream restored! Aimasi's black filter cartridge seemed to be dangling in the case; Changing the pads fixed it. If you have Aquasana filters, keep these pads just in case. I may update this once we've used filters for a while. So after 10 days the filters are working as they should. nevertheless good flow, no groaning noises!
