ProTec PC-1 Humidifier Tank Cleaning Cartridge (Pack of 2) Reviews
That may be a 1-pack instead of a 2-pack, but that's still only $9.76 instead of what Amazon is charging. True Value Hardware has them for $4.88. Do some internet shopping before you buy because these are a lot cheaper in several other places.
It is very expensive and I am not sure this really cleans the tank any better then you could do with just washing the tank out yourself once or twice a month.
It is easy to use. It is hard to tell. I was told this works.
bleach every few fill-ups. However, who would buy this item when the exact same product is available from KAZ or Pro-Tech, and on Amazon for about FIVE DOLLARS for a twin-pack. These are good if you don't want to add 1/8 tsp.
