Sorry, there was a problem. Please try again later.Hi Dee, this is Kelly with Dyson. You'll be happy to know that during testing, cigarette smoke was specifically tested to help determine the filter life and whole room purification. From these results 99.97% of allergens and pollutants as small as 0.3 microns are removed from the air. We hope this helps. Best wishes, Kelly Dyson Customer Support
