Blueair 411 Auto Air Purifier: Trusted Review (Performance Test)

[@rvtBC]

You ranked this very high and effective, but also commented that it didn’t do a great job with removing cigarette smoke. We get smoke smell from a neighbour and hoped to find an air purifier to remove that smell that wafts over into our space. Will this do the job you think?

You could have your neighbour fed to the fishes for a fee ofcorse.

Well many houses in rows close to eachother using wood fire and it's cloudy...i'd like fresh air. But if sigaret smoke is not purified well, i do not expect tge wood smoke is?

Really new to air purifiers..what does it mean with you mentioning it being ionized and does it negatively affect health in anyway?

[@joadventurestv]

You should do a video of the new Blueair 411 auto Vs The Xiaomi Mi 3H. Let see how that goes. Personally I have a new Blueair 411 auto. But I’m planning on buying the Xiaomi Mi 3H. Because the Blueair doesn’t have Smart features and it’s not taking out odors very good.

I will do it, thanks for the suggestion!

What is the difference between this Blueair model and the Blueair 411iMax? Thanks I am comparing the Blueair 411iMax to the Levoit Core 300S.

Blue air every time , the others are not good but a little fancier. Plus Blue air is lowest on my energy consumption. Win win …. The other one my friend has and is not great sorry x

[@goberianchloex3646]

Lovoit is rubbish and ur better having nothing and opening a window probably the same result x

[@sonyaphanwijaya2893]

Hi, thanks For the explanation but still confuse Which one to choose between levoit core 600s and blue air 3410 , my main concern is For rhinitis allergy. Thanks !

[@AirPurifierFirst]

I would go with the Levoit if you plan to use it in a large room, and with the Blueair for a medium-sized room.

Hello, are you sure about your measurement of noise ? Because when I’m listening to your review of levoit 300 it makes clearly more noise (night mode) but has lower dbA than the blueair Thank you

[@AirPurifierFirst]

Hi, I have been using the same noise testing tool since I started reviewing air purifiers. But right now, I use a different audio recorder, and that's why the noise recordings in some older videos sounds a bit different (louder). Watch any new comparison where there is the Core 300, and you will see the difference. In the past, I used a camera built-in microphone to record motor noise, while now I use a Sony voice recorder.

@@AirPurifierFirst ok thank you very much for the explanation :)

What’s the difference between the 411 and the 511?

[@AirPurifierFirst]

The 511 is slightly more powerful.

[@User_005]

In the video it says rooms up too 100sqft but on Amazon where I bought it from says 900sqft 🤦‍♂️

[@salibat7246]

Up to 900sqft

[@AirPurifierFirst]

The Blueair 411 Auto can clean the air once in 60 minutes in a 912 sq. ft. room, which means it has an ACH (air changes per hour) of 1. However, the industry standard is 4.8 ACH, according to AHAM. In this case, it is 190 sq. ft., not the 912 sq. ft. as the manufacturer said. So, I use 4.8 as the standard for suggesting room size for an air purifier. For example, the more polluted the room is, the larger the ACH number you would need. I wrote a few articles on CADR, airflow, and the explanation of other standards, which you can find on the Air Purifier First website.
