    Great price on filters for our Blueair air purifier

    Posted by Connie on 29th Jan 2013

    Our Smokestop filter is a great Blueair air purifier. Definitely works better than other purifiers we've tried. So happy to find these filters online for a good price. The filter makes such a difference in our business!
