I have been using the product for several days and am very satisfied with it. It's easy to clean and doesn't get mold easily as long as you use the filter and change the water every day. If you don't run the machine on a daily basis, it's better to empty the tank to avoid mold. The matching filter is very effective in eliminating white dust - I haven't noticed any in the past few days. The machine is also on the quieter side and it's good for use at night. Finally, one tank of water lasts for at least 12 hours on low. Make sure to use filtered water and a filter to avoid the trouble of dealing with mold!
