Can't tell if it's working
I've had this for a while now and still can't tell if it's working or not.  There haven't been any smells to get rid of so it's not so easy to tell.  I mainly bought this for my allergies.  I think it works?  My allergies haven't been as bad but I think maybe this is too small.  It is a bit loud for how small it is.
