When I received the Conair medium Room Air Purifier, I was excited to open the box and start using it right away in our bedroom. My husband read the booklet included and was eager to set it up and see how it worked. He put it on his nightstand and turned it on when we went to bed that evening. We have never used an air purity, so we didn't have any preconceived ideas as how it would perform. 

Pros:
Noise from the fan was soothing. We like to have white noise when we sleep at night. 
My husband noticed his cpap machine hasn't been using as much water at night.
Our eyes don't seem as dry in the morning. We have 2 dogs that sleep with us at night and I think it helps keep the dander down. 
The control panel is easy to use. 

Cons:
The lights from the control panel are very bright. It lit up our bedroom. We had to put a post it note over the lights to get some relief from it.
