Kaltech MY AIR This is a neck-worn small air purifier. Equipped with photocatalysis for easy virus protection! I purchased this around the end of the COVID-19 pandemic, but I never used it and just left it. I recently used it for about three days, but it seems like it's going to be put away in the closet again, so I'm putting it up for sale. Due to shipping costs, the box shown in the photos will not be included. This is a used item, so it is sold as-is. Please understand this before purchasing.
