Review on 🚰 iSpring FT15 Inline Post Carbon Filter Replacement Cartridge - Superior 5th Stage Filtration for Ultra Clean Water (Pack of 1, White) by Darrin Parasson

I reordered this filter from Revain. After 4 reorders, iSpring appears to have redesigned the 5th stage filter. I had to sit out installing a new filter set as you have to order a knee for the filter to work. It sucks that iSpring changes how their filters fit their systems and doesn't include all the necessary fittings. This sort of defeats the purpose of buying replacement filters from the manufacturer if they are not ready to use out of the box. It will take about 10 days to receive the sheet we should order from iSpring. I think I'll switch to cheaper generics for the next round of replacements.
