Hubby has some that he uses to clear his sinuses when he starts to get a cold. They work really well for that.
And I used some citrus the other day to get rid of the "musty basement mixed with 2 dogs and 2 cats" smell in Vet2Be's room.
My friend (who is really into essential oils) told me to use a diffuser that doesn't heat the oil.
I don't have one.
Here's what I came up with that seems to work just fine!
|It's a napkin with the essential oils on it clipped to the front of a fan.|
Now his room, and the basement, don't smell like a mixture of stale air and dog. Yay for me!
I might try it on the evaporative cooler next.
It's called a 'swamp cooler' for a reason.
