When our son moved back to the area we were concerned about his allergy to cat dander now that he would be visiting more frequently. We were very satisfied with the filters for dust allergies but the cats posed a different problem. Our worries were unnecessary. The Blueair 400 filters did a fantastic job - even when the cats decided to jump in bed with our son. We highly recommend these filters and the Blue Air purifier.

We have two of these machines in our offices and they work great. The filters are changed every 6 months. I suffered with severe asthma due to building conditions and this filter has made a major difference in my breathing in the office. Very quiet too. Worth every penny.
