If you are reading this before placing your order and you own a 331i+, this is the wrong filter. That + is a larger model and this one won’t fit. Don’t be like Bob. Read the description very, very carefully! 😆😁 On another note, I love my Blue Air!

Exactly what I needed

I placed the purifier with the SmokeBlock filter in a corridor for an hour, where the smell of burning was lingering strongly. It did not clear the smell of smoke at all. Beyond the corridor, the house was relatively clear. The VOCs had pooled in a small area, which this filter wasn't able to clear. For odours, I have only found the Blueair Signature purifier to be effective and produce actual clean-smelling air during and after a smoke event. If you actually have issues with smoke (for us, the above refers to mixed waste burning), I would purchase the latter purifier. If you already have the 311i, this IS an upgrade - it does a better job that the original filter overall.

Fits perfect works well

Helps reduce kitchen smoke / general air quality improvement. Moderately improves cat allergies by reducing dander, though not a complete solution
