Please judge by the photos. Photos have been added. Used for about 4 years. The humidification function seems to be slightly less responsive. Please understand that this is a used item before purchasing. The air purification function is fully functional and works perfectly. I am selling it at this price because I have only done a light wipe-down cleaning.
