These EnviroCare scented vacuum tablets were intended to be placed inside of your vacuum cleaner bag to provide for a more enjoyable sweeping experience. Just one tablet will fill the room with a pleasant smell rather than the smell of old dust and pet dander. They can also be placed near old laundry hampers and other miscellanious, odor problem areas. Leave your house clean, AND smelling clean, so you can free your nose from all those pesky odors.
