We love it!
Right out of the box it was ready to use. We plugged it in and turned it on and shortly after, we could tell the difference in the air in the rooms. We all seem to have some kind of sinus or allergy problems and we have started breathing better. The air coming out is so fresh-smelling. Thank you for a wonderful product!

Thanks for the great feedback on your Blue Pure 311i Max. We’re glad to hear it’s working well overall. For the red filter light, pressing and holding the fan button for about 15 seconds should reset it once the filter is properly installed. Here's a helpful article for you: https://www.blueair.com/blogs/blue-pure-max/the-red-filter-light-indicator-does-not-reset-after-replacing-the-filter-bpm?_pos=3&_sid=72c58261c&_ss=r

Thank you for sharing this feedback. We’re sorry for the trouble after replacing the Blue Pure 311i+ Max Allergenblock Filter. The purifier should recognize the filter once the indicator is properly reset, and we know it’s frustrating when that doesn’t happen. We’ve reached out to you directly so we can help get this resolved and make sure your purifier is working as expected.

It makes a difference
We noticed the difference in our air after the first day. On lower fan speeds it is very quiet and even on medium or high speed it is quieter than many others. The air quality monitor was showing the air quality as bad and we thought there was a problem with the monitor, but discovered that our humidifier caused this problem. When the humidifier is off or on a low setting the air quality monitor shows it as good.
