“I am truly blessed to have access to this air filtration unit! I initially purchased the PA3900 to scrub cigar smoke from my indoor smoking room - now, what I found is that the smoke particles that held the smell were too fine to be filtrated out but the silver lining was that the air purifier was amazing at clearing out the pollen, dust and other irritants. So the unit does an amazing job at ridding the air of the heavy particles but I can still smell the smoke settling - otherwise 100%!”
