Product review (3 stars): Replacement filter
Very fast delivery. Filter sorks well. It must be turned over every 1-2 days to keep it moist. If it dries out, it may begin to grow bacteria. Rinse it at least once per week and be prepared to change it monthly. I am satisfied with the Honeywell Humidifier that I purchased it for. I would like to be able to keep the filters in the appliance for longer than a month ,but the bacteria (and filter) begins to smell like a wet dog.
