I received the Conair room air purifier about a week ago. I wasn't sure what to expect from the product, thinking my homes air was clean with us being " clean freaks". The product was easy to set up and does not take up much space. we ran the Air purifier for a week straight. After one week of running the purifier, we checked the filter. We were extremely surprised to see how much dirt the purifier caught. I would recommend this product to everyone after seeing how it worked in my house. I will always have a purifier running in my house after seeing the results we had.
