Bests & Worsts Reviews from Amazon

This product did not seem to make a difference in air quality. The product has a warning label that says that “this equipment should be inspected frequently and collected dirt removed from it regularly to prevent excessive accumulation that may result in flash over or a risk of fire.” I did not see this warning label in the product description when I purchased the item; otherwise I would not have purchased it. There are no instructions in the box about how to remove any dirt from the product. If I could return it I would but it is past the 30 day return date.
