It’s really doing something!

I placed my 311+ Max in my great room, and left it in automatic mode. When I cook or vacuum it kicks into higher gear and runs until the light is blue again, so I knew it was doing something. But when I went to replace the filter for the first time...WOW, just wow. And to think I was breathing all of that before. I immediately ordered a second one for my bedroom.

I like my 211 better. 311 controls not as easy and only 1 cloth filter.

The original filter was pretty dirty, so replacing it was overdue and am looking for continued cleaner air than otherwise without it. My wife likes it cause of less dust in the house.
