What is going on with dental offices? I know the owner of a small clinic that only does cleaning. She was already stretched pretty thin before she had to buy air purifiers so she did her best to run some ductwork and asked me if i could check to see that it meets the fresh air and air changes per hour requirement. This is a strip mall with a single furnace in the back.
