Product review (5 stars): Happy with product, not happy with the seller
I bought this product because I was sick and tired of having to wash and soak my humidifier and filter with bleach every week, just to find out that mold was growing in the filter a few days later. This product is great. No mold and it smells clean.

Since this is not an expensive product, I bought a replacement filter from the same seller (buy-it-now) as well because it said it was a Holmes filter: it is actually a generic one. It works, but I am not happy with the false advertising. I disliked a lot that I purchased those 2 items at the same time and I was charged DOUBLE shipping because shipping charges apply to every item purchased, so I will NOT buy from this seller again.

And precisely today, I found this exact same product at my local Rite-Aid... arrrrrrgh...
