Product review (5 stars): These work great
I purchased the tower humidifier a few years ago at the local hardware store. They stopped carrying the filters two years ago at the local store but I found them at Amazon. I like the tower humidifier because it is easier to refill and clean than a larger tank style humidifier. It's a bit noisy but it handles the whole first floor, so once it establishes the humidity level you set, it runs only when needed . Thanks for carrying the filters!
