Used for a total of about 10 days. There's a family member who is sensitive, so it was only brought out and used when they visited. I was concerned about scratches or dirt due to the low frequency of use, but there are some marks that appear to have been made when taking it out and putting it away. There are small black marks here and there, as shown in the photos. It looks clean at a glance, but please be aware of the details if you are concerned. Operation confirmed. White TruSens Z-2000 air purifier, with instruction manual and warranty. - Brand: TruSens - Model: Z-2000 - Color: White - Accessories: Instruction manual - Warranty: Included Thank you for looking.
