Work great but a LOT cheaper elsewhere.January 5, 2009 Do some internet shopping before you buy because these are a lot cheaper in several other places. True Value Hardware has them for $4.88. That may be a 1-pack instead of a 2-pack, but that's still only $9.76 instead of what Amazon is charging.
ProTec PC-1 Humidifier Cleaning CartridgeDecember 29, 2008 Noticed that when we began using this cartridge the filter did not need cleaning as often. Appears to be working very well - does what it says it does.
Preventing fungusDecember 28, 2008 I was told this works. It is hard to tell. It is easy to use.
Pro-Tec cleaning cartridgeDecember 21, 2008 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.
Buy Elsewhere for under $5.December 5, 2008 1 out of 1 found this review helpful
These are good if you don't want to add 1/8 tsp. 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.
