This was very easy to replace. The demonstration video on the app shows all you need to do. I pulled off the used one, then slid on the new one; there are tabs marking the top so you don't put it on upside-down. No problems.
I would recommend this to a friend!

Just installed it and 5 days later it’s telling me I need a new one!
No, I would not recommend this to a friend.
Response from www.blueair.comBy Blueair Team, Blueair, September 8, 2025
We’re sorry for the confusion with your Blue Pure 311i Max Particle + Carbon Filter. Your unit likely just needs a filter timer reset after the filter replacement. To do this, press and hold the Fan Speed button for about 15 seconds until all LEDs light up, then release. The red filter indicator will blink three times and disappear. We’ve also reached out directly to make sure everything is running smoothly.

Love the automatic sensing of air quality and its adjustment of fan speed to pull in more air when qualify is low. Love the Bluetooth app controlling the filter. Great product!!

Works great. Easy to install/ replace. Works well and lasted a year in a single pet home with almost daily use. Replacement filter arrived quickly and ships flat in a small box.
I would recommend this to a friend!
