Handy Air Sanitizer
This is our second air sanitizer.  We like to bring one with us on vacations to help the air quality in hotel rooms.  Since we have allergies, we keep this one in our living room and another in our bedroom.  They are very handy but you can certainly hear them like a small vacuum cleaner.  I haven't noticed a decrease in dust or anything, but the air does seem to smell better.
