Product review (1 stars): Don't get this type of humidifier!!!
The Holmes humidifier is the same old trick where they sell you a fancy printer for $15 and then you have to buy an ink cartridge for $39.99 every other week.
The filters are not cheap and if you are concerned about your health you would replace them every other week since they begin to smell like a stale rotting pond.
Cleaning the Humidifier is not a walk in the park, it is not built for easy cleaning.
I recently bought one of those ultrasonic humidifiers that don't require a filter and are easy to clean (you just wipe the interior).
