Great replacement filter
I’m happy with this filter. It’s fits perfect in my blue air 403. Air flow seems the same, but I usually keep on low. Super easy to replace. As some have mentioned, there was a slight plastic smell at first but it went away in a day of running it.

Awesome and Cheaper BlueAir Filter
I had a bit of a problem putting filter in, but believe it is working as good as the air filter sold by the company I have been using. Price went up from $59.99 per filter to $89.99. This is when I started my search on Amazon. Great price. I will keep ordering.
