Lampe Berger is an Air Purification System. Light the burner for 2 minutes, blow it out and leave it uncapped for approx. 20 minutes, depending on the size of your room. Cap it off, and it will continue to clean the air for up to 3 hours. Takes bacteria and odors out of the air. Lots of fragrance options, or a neutral, if you prefer not to have a scent going into the air.
