“According to many sites thec211 plus does not have a carbon filter. I have owned the 211 plus and 411 and can still pick up smells in my 750 sq ft house. Is there a carbon for smells? What is the micron size?”

The 211+ is larger than the 411. Alone, neither is adequate for your size house.

I have three 211+ Blueair units. Each one is good for 540 square feet. So, I have very pure smelling air in my home. The stated micron particle size is 2.5 microns which I was looking for.
