Blueair 601 Air Purification System

I have congestive lung disease and live in an apartment. When a new downstairs neighbor moved in, who is a heavy smoker, the smoke came up through the floorboards and into my place. I was literally choking to death. I tried taping over all the electrical outlets, putting special filers in the vents, and blocking every place I could think of where the fumes were entering. Nothing worked until I got the Blueair 601 with the smoke filters. It turns on automatically every time it "smells" smoke. I know exactly when my neighbor is smoking by when it turns on, but it filters all the smoke from circulating into my place. If it wasn't for the Blueair 601 I would have to move.
