Good filter. Seems to be right on point when I cook, she turns on. Air is clean with in minutes and this is without a stove exhaust system
I would recommend this to a friend!

Unit Won't Reconize New Filter

I've tried everything suggested from your website, but I can't get the Protect 7400 to recognize the new air filter. In spite of these efforts, the unit still shows the filter at 0%.
No, I would not recommend this to a friend.

The filter replacements slipped in like a breeze. Always amazed me how much dust is picked up in the prefers that I’ve been vacuuming out monthly.

I like the Blueair filters. They keep the air clean and remove a lot of virus from the air.

Terrible app and email performance!!!!

When you change the filter. For some reason you need to reconnect to the internet via the app. Well that works poorly!! I had to delete the device to be able to connect it. Once connected the app isn’t giving me the reports on the particle counts. Very poor support via the app as well. You can do better I’m sure. All of this has happened twice since purchasing the purifier. Now the requested critique “Agree & Submit” entry isn’t working! Just down graded my rating again!
