User Manual / Which Filter
on January 5, 2026
Posted by: katie
from US
I cannot find the user manual for my Blue Pure 411a Max and I am also unclear what filter I should order to replace the existing one. Which filter (Particle & Carbon, SmokeBlock, or AllergenBlock) will filter Covid & flu viruses out of the air? Thanks.

I bought the wrong filter / I have the old model 411 and now can't find filters for them - I thought these would fit and they do in not - can I return them?
No, I would not recommend this to a friend.

Great Value for HEPA Air Filtration

Have been using this 411a for about 2 years, packaged with a filter subscription and very happy with it. Even though I don't have the benefit of a wifi connection, the sub reminds me to do filter changes, & I do see a difference in the room's air quality. I run it 27/7 and it is very quiet.

The Best

We love both our Blueair Filters. I only have one candle left that's not battery operated. When I light it in the kitchen that is about 30' away from the filter it turn to red. Amazing.

The air filters make life so much better if or when someone close has allergies. BlueAir has helped several family members and friends.

Excellent Air filters
on April 29, 2026

We love the way these work. They do a great job for us. We have three in different areas. Two of the machines have developed a low grinding sound. We have changed filters and cleaned them, but can't get rid of the noise.
I would recommend this to a friend!
