Easy to use and very portable
I really like this product and would give it a 4.5. The only thing I don't like about it is that it isn't silent. If I plug it in near the bed, I hear it. Otherwise, it's a great product , easy to use, very portable (easy to take on trips) and effective. I have a dust mite allergy and I never have trouble when I use this.
