Make sure to order the correct size
This is a fine filter for the air purifier. However, be aware that the 311 is not the same as the 311i Max, and the filter sizes are different. I made the mistake of ordering the wrong one and spent quite a long time trying unsuccessfully to make it fit. Once I returned this filter and ordered the correct one, it slid on like a hand in glove.

Quality product.
I’ll only buy manufacturer brand filters for my purifier. Easy to install and lasts a long time before needing to replace.

Works well
I love these purifiers & filters. It runs so quietly and kicks on higher when I’m burning candles or if the windows are open and there’s a high allergy count. The filters seem to last for a long time, too.

Overpriced but functions as expected
This filter works well with the product, as you would expect. It definitely filters out the stuff because when I replaced my first, it was filthy. The installation process was pretty easy but the instructions help quite a bit.

Fits great, just double-check your model
I read some reviews here that this filter was too large or didn’t fit, so was a bit wary. I have a Blueair Blue Pure 311 Auto which it fits perfectly on. Blueair it seems has a tendency to name their air filters very similarly, so just make sure to double-check your exact model. The filter itself makes a difference in air quality so I felt it was important to purchase a genuine one versus a cheaper one. My filter is never very dirty after 6 months so sometimes I use a filter for a few months past that timeframe – I just reset the light and put a calendar reminder for myself to change it a couple months later. All in all, great product.
