I am truly quite impressed by how well this little air purifier works on smells.  I dehydrate my own peppers for chili powder, and when I do, it's like my entire house got pepper-sprayed.  But I started running this air purifier, not even on full blast, and it took the peppery sting right out of the air.  I also really like its nighttime feature where you can turn off the lights while it runs.  A very nice air purifier.
