Advanced Vapor Plug Refill, 1-Count, 40-Hour Refill Unit (Pack of 3)

this is one of the few products to help make the air around you more breathable-that has any effect at all.It-however--has been removed form the market--so being able to access it--means you are over paying-and so you buy less.I use this to make the room better to sleep in for a cat with some sinus issues. It does help- But it lasts a very short time.So-In a smallish room-you may get to have it be effective-on 3 -8-10 hour nights.There really is nothing else out there--to use and help with breathing comfort.

Works as advertised.

I love how this product fills the room with the scent of menthol/eucalyptus. It sures helps me to avoid nasal/sinus congestion.

The smell last a long time and is very easy to plug in.They cost too much, but I think they are worth it.
