BLUEAIR Air Purifiers for Large Rooms, Cleans 3,048 Sqft In One Hour, HEPASilent Smart Air Cleaner For Home, Pets, Allergies, Virus, Dust, Mold, Smoke - Blue Pure 211i Max (411)

This air cleaner works very well in my home. I noticed less dust, which was my biggest problem. It is quiet and I love the fact that you can use the app to adjust it whenever you need to as I have one upstairs and one downstairs. I can adjust the speed or turn it to auto or even turn it off whenever I need to without getting up by using my phone even when I’m not home. I also like that you can monitor what the air quality was throughout the day. It picks up odors, like hairdryer and kitchen odors. And adjust the speed on auto according to the odors it picks up and then it adjusts back once the odor has been eliminated. Excellent product. Worth the purchase. I purchased a large and smaller size. Very happy with its performance,

I purchased this air purifier to supplement a larger Blueair unit (211i MAX) have for cleaning the majority of our 1171 sq ft condo. This purifier sits in the main hallway to cover areas the larger Blueair unit does not. The setup was fast out of the box. Wi-Fi is enabled, so it was just a case of adding it to my BlueAir app on my phone and connecting it to my home network. The device provides detailed air quality readings on the app and can be programmed for on/off schedules, display brightness and air filter life; the latter is important to know when deciding to reorder new filters. Maintenance is quite easy: each month, I vacuum the outer pre-filter and open the unit (turn power off) to vacuum the filter chamber. The app will advise if the pre-filter needs cleaning. There is a geofence option [called 'Welcome Home', to turn the purifier off if you are away at least 3 km and turn it on within the radius. The unit is well-made and does the job and why I purchased a second unit.

Great machine. You pay for the quality but it's quality you get. I use it in my bedroom for allergy season. On night mode, it is impossible to hear. On level one, you can barely hear it. I keep it on level one. Automatic works well - the speed increased when I had a smoky air fry. The design is nice, and well thought out. The fabric prefilter is super easy to remove and wash. The Bluetooth connection works well and it's nice to see the current and history of how clean the air is. There are no cons here. Great unit.

This air purifier changed our lives by eliminating fine dust (due to living in a windy desert). Our home stayed clean and allergies were greatly reduced. I sang it's praises and even gave one as a gift. But one month before the 12 month warranty expired, it just stopped working. I contacted customer service who replied quickly with 4 different procedures to try. Nothing worked. So they promptly sent a new unit - Hooray! But less than 2 months later it did the same thing, just kept turning itself off. I almost cried, because I REALLY like this unit - it's quiet, efficient, easy to maintain with a valuable phone app. So again I emailed Customer Service, who replied the SAME DAY (who does that?). Without any questions or insinuations - a new unit was sent the next day. I'm hoping it was just a weird fluke that both units did the same thing and this one will hum along for several years, because IT REALLY WORKS - providing clean air.

This replaces my 10 year old air cleaner and the sound level is noticeably quieter. Love the beauty appearance. We live near the beach with a constant breeze so having the windows brings in a lot of dust, which the device does a good job for trapping. My air smells cleaner because of this device.
