Review on Tyent Standard Ionizer Filter Replacement by Stacey Vang

One of the packaging around one of the filters has been opened, otherwise it arrived on time. Also, I changed the filters for the first time. Black flakes came out in a couple of weeks. I usually put in new filters and a few glasses of water is enough to get rid of the black flakes. I don't know if the filter is defective or not. Sending it back and buying a new one is too expensive.
