Blueair 501PF HEPASilent Particle Filter, 1 Set of 3

Comment: The Blue Air filter I ordered was awesome. I use it in my office. My office is in a manufacturing building. Saw Dust, Adhesives, and powerful Solvents. The exterior of my office door is constantly covered in dust, even with daily cleanings. My office has black plush carpet and is designed as a movie theatre and sound room. The blue air filter is the next best thing to having a window of ocean air. i occasionaly have lunch with clients in my office and the food smell disappears within half hour or so. It also works great along side my humidifier. I have terrible sinus problems but have been able to stay in my industry because of this air purifier and filter combo.
