LOVE THIS LITTLE THING!!!!

Really does what it is design to do. Really help with my breathing after only after a short time using it. Love that its light weight and small, so I travel with most places I go and can place it in my already cramp up room. Device is easy to set up and use. Would definiftly recommend to those with allergies because it help clear it up when its reall bad after a long hard day outside. Will definifly have to invest in a second maybe even a thrid on to leave at two houses I spend alot of time at.
