Review on WellBlue Alkaline Blue Replacement Filters by Cody Stroop

I ordered it A FEW DAYS AGO. six months after purchasing a fully working Wellblue pitcher that was working and filtering well until a few months ago. I was finally able to replace the cartridge with these NEW cartridges and guess what happens? It works for 3 days and then stops altogether. I even took out the cartridge and shook it like the instructions said and still NO DIFFERENCE! The original cartridge that came with my pitcher worked well for over 6 months, although 3 months is recommended. I don't expect to have no alkaline or filtered water (fluoride and all). Wellblue logo all over. Buyer Warning!
