Review on Hydrotech 41400008 41400009 Replacement Cartridge: Quality filtration for improved performance by Chris Byers

I thought these were the same filters I've been buying for years but something went wrong. The water came out dark gray for the first 10 minutes, then turned to yellow urine for another 20 minutes or so until I emptied the holding tank twice. The water is finally clear, but it tastes terrible.
