Humidifier replacement filter

I've been using these filters for a couple years now and am very pleased at the performance they provide. My daughter suffers from asthma and allergies and as soon as she uses the humidifier it helps lesson her reactions. It's also good in helping fight colds as it helps with the dryness in the house.

As advertised

This is, as far as I know, the only filter you can buy for this machine. Fortunately, it works really well, and does what it is supposed to do.
