Great air filter
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.

Just installed it and 5 days later it’s telling me I need a new one!
1 reply from Blueair team - 2 months ago
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.

Easy To Do
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.

60% Left After Total Bathroom Remodel
We just hit our master bathroom remodeled. We have a en suite bathroom. The demolished.the porcelain tile, tore out the tiled shower and floor, remove the bathtub and totally replaced a window, built a wall and put in new baseboards. We had changed our filter about three months prior and I thought for sure our Blue Air purifier would need a new filter after all that. I checked the app and we still had 60% left on our filter. That’s quite a task for a little air purifier. Like the little pink bunny for batteries, it just keeps on going.

Filters have a smell at first
I was a bit disappointed in the chemical smell when I first started using the new filter. It’s better now but took a few days to dissipate. A bit ironic given that it’s supposed to help the air be more pure..
1 reply from Blueair team - 3 months ago
Thank you for sharing your experience with the Blue Pure 311i Max Particle + Carbon Filter. We’re glad the odor has improved, though we understand it’s not ideal to notice any scent at first. As with any new product, a slight odor may be noticed that is inherent to the material. Running your air purifier and ensuring your space is ventilated will help dissipate the scent quickly. We appreciate your patience as it settled in and hope you're now enjoying fresher air as intended.

Filter issues
I purchased the blue air filter and my air purifier is still saying my filter is only 50% So I’m not a happy customer right now. I love the air purifier but why is my filter only saying 50% I just purchased it.
1 reply from Blueair team - 5 months ago
We are glad to hear that your love your 311i Max purifier! When replacing the filter in your 311i Max, the filter timer needs to be manually reset—otherwise, the display may still show the previous filter’s usage. To reset it, just press and hold the fan speed button for 15 seconds until the indicator resets. If you experience any issues, please don't hesitate to reach out to us directly, we would be happy to help.

A picture is worth a thousand words
All you need to do is look at the photo - the Blueair 300i+ Max and its filter system deliver on what they promise! I have an indoor cat and I keep the purifier a few feet away from his litter box. My one regret is not buying this system years ago.

311i & 411i
This was working good until I changed tge filter, now both of my blu units run constantly they used to just turn on when the air was poor or not clean now they will not stop running i had to plug them both.
1 reply from Blueair team - 8 months ago
Thank you for your feedback regarding the 311i & 411i Max. It sounds like the issue you're experiencing may be due to a dirty sensor on the back of the unit. To clean the sensor, you'll need to unscrew the sensor lid on the back of the device and use a cotton swab to gently clean the sensor area. This should resolve the problem. We have also reached out to you directly to provide further assistance and ensure the problem is resolved.

Great Product, quiet, gets rid of dust in the house, smoke and doesn't use much electricity. Also the WiFi control and the information it gives you is great. I liked it so much I ended up buying two more.

excellent air cleaner
Since purchase i run it on high 24/7 , helps considerably with allergies and a few months ago when we had lots of smoke coming down from the Canada forest fires, this filtered all the smoke out. I dont use the app or blue tooth, I just turn it on high and run it, I vacuum the filter about every 3 months and change filter about every 6 months .

Works Well
The Blue Pure works very well. I wish that there was more flexibility in how to order a replacement filter, and from what source. That keeps me from giving the product five stars.
