This is a large-capacity Plasmacluster next unit. In our home, we use a separate humidifier, so I haven't used the humidifying function. I haven't used it since February of this year. I've cleaned it to some extent, but there's some dust from storage, so I've marked it as having some dirt and scratches. (Also, there's a slight white scuff on the front left side.) There's Velcro on the back for attaching disposable filters. All functions work perfectly, but please refrain from purchasing if you are overly concerned about the condition. I would like to sell it to someone who understands that it is a used item. I will pack it securely using wrapping cardboard, etc. I think it will be especially useful in the coming season when it's easy to catch a cold.
