I bought three refurbished BreatheSmart
I bought three refurbished BreatheSmart 45i's. They all work great and you would never know they were refurbished.
I am very happy with the job they are doing. I also have a new BreatheSmart 75i in the main area of my apartment. With the three 45i's in each of my bedrooms, my home is much safer air purity-wise.
