I have chemical allergies and am very sensitive to certain smells. I had my kitchen remodeled and the the smell of the stain varnish that was applied on the cabinets was really strong to the point that I was having a hard time breathing, but luckily I had purchased the GermGuardian in advance before starting the kitchen remodeling and it was a life saver for me. I could not believe how well it got rid of the petroleum type smell from the stain varnish.

Pros: Really works in removing odors
Cons: None
