BLUEAIR Bedroom Air Purifier, Small Room Air Cleaner Dust Pet Dander Smoke Mold Pollen Bacteria Virus Allergen, Odor Removal, for Home Office Nursery, Washable Pre Filter, HEPASilent, Blue 411 Auto

Easily one of my best purchases of 2025. After using it for a short time, it genuinely makes you wonder how you ever lived without an air purifier. The air quality improvement is noticeable, especially in a bedroom environment. The room feels fresher and less stuffy, and it has helped significantly with dust and general air cleanliness. The app functionality is excellent, simple to set up, responsive, and useful for monitoring air quality and adjusting settings remotely. The unit itself is fairly large, but this clearly comes down to the size of the filter, which inspires confidence rather than being a negative. It feels well built and designed to handle larger rooms properly rather than being underpowered. Noise levels are impressively low. Even when running continuously overnight, it is quiet enough not to disturb sleep, which was a major deciding factor for me. Overall, a very effective, well designed air purifier that delivers exactly what it promises. Highly recommended for anyone considering improving their indoor air quality.

Seems ok, and phone app is useful. I've been using this for approx one month now and the phone app connected to this device is super useful to check on the current 'air quality' level as well as viewing how much of the filter is 'left' until it is recommended to be changed. My air quality is generally good or excellent on most days, and there is still (after one full month, 90% left) of my filter for use. So, it isn't working hard and you can probably get 10 months or 12 (if you push it) per year with each filter. Operationally, usage is very quiet, which is solid plus.

Just started using it in my bedroom and I can already feel the difference. The air feels lighter and cleaner, and it’s super quiet — perfect for sleeping. Easy to set up and looks nice too. So far, very happy with it

It appears to work as per all the claims. I put it in the main bedroom because the house is 1900’s with a wooden floor and I was convinced that dust was coming up from the floor. The unit quickly told me that the air quality was great and there were no issues. The only time it moves to mid speed is when sorting laundry or changing the bed (cotton lint dust) so I know it works. The app is a good way to visualise the use and auto mode takes care of things. I’ve struggled to get the top indicator lights to dim completely at night which is a pain - and I’m kinda disappointed that it finds little issue in the room so I’m not really benefiting from the unit.

Great product. Had it around 2 months now and I'm shocked at the amount of dust this thing has filtered out the air. I bought this as I wake up with a blocked nose and a feeling like I've been tickled with a feather in my nose. Was dubious that this would make a difference but I was at my whits end so gave in, bought it and now wouldn't sleep without it on. Ease of use: Being able to store it behind my tv and be able to control it by the app is such a great thing. Easy to use, press the power button and it comes on, slide the fan speed and it changes quickly and an easy button press for night mode that you can barely hear

Works perfectly fine. Connectivity from app to air purifier could be improved. Makes the air feel cleaner. Has helped with morning allergies. App includes useful information such as when the filter needs changing. Not very loud on fan 1 and 2 but is quite noisy on fan 3. I have found the schedule feature helpful.

Could tell air was better eighin 1 hour

I used to have a blueair 211, the square one which worked fairly well for about 4yrs until it started making a high pitched whine and the fan blades were clogged with dust with no way to get in there to clean it. So I bought this one. Very lightweight but also had an annoying high pitched sound from the start especially noticable on the first speed. I quickly noticed within days this is useless at keeping dust at bay. My surfaces were thick in a few days whereas my 211 had kept it down despite running on a low speed all the time and this one at speed 2. I suspect the thicker prefilter on this may be the suspect. My nose was still stuffy all the time unlike with the 211. Whenever I needed to reboot my router this purifier would not connect with the app meaning I had to delete it and reset it up again. There's no way to just reconnect in the app itself. At the 3 month mark it refused to connect with the app, it also started having power problems. Suddenly and repeatedly the fan speed would stop for a few seconds with a flashing white light then come back on again. Thankfully Amazon were fabulous and let me return for a refund. I will be purchasing a different brand and I doubt I'll be coming back to blueair anytime soon.

The item arrived quickly and worked as intended, shipped directly from the US by Amazon. It seems to be high quality and looks good. My understanding is that the benefits of this unit are: 1. looks good, 2. uses washable fabric prefilter to take some of the work away from the hepa filter, 3. contains an air quality sensor, 4. has a night mode which is quiet and where the light is dimmed, and 5. probably more importantly, uses the high quality hepa filters from Blueair. My wife trusts the Blueair filters and this is probably the most important differentiator for this product. In other respects, it is similar to other filters which are available. If you like Blueair, I'm happy to recommend this.

Love it!

Very quiet in sleeping mode .

Having an AQI sensor with an auto mode is pretty rare for purifiers at this price range. BlueAir is really cool for creating something inexpensive to be a set it and forget. I’ve tested and tried many different air purifiers and while I have a favorite already, this one really deserves its praises. For starters, I want to say this is definitely a bedroom-centric purifier and isn’t meant for larger open concept spaces (Opt for the 311 Auto for bigger area). The 411 auto is virtually silent on level 1. Level 2 is also pretty quiet but has a very gentle breeze sound (personally my fav for sleeping bc the white noise is calming). Level 3 definitely is a jump in sound but is good for brief quick air cleaning. Auto mode is pretty accurate with detection rate. I put out a candle that was relatively close proximity to the purifier and the sensor light turned red and gradually revved up to sift out the smoke. In another test, I blew out a candle that was further away from the purifier across the room. The sensor did take longer to begin revving up the fan (about 5 mins give or take) but nonetheless still managed to detect. I find dissipation of odors and smoke to be pretty decent. Today I was indecisive about outfits and tried on many diff things while looking in the mirror and I guess all the dust and lint kicked up and got the little guy revving up. All this to say, the AQI sensor and Auto Mode is great! Other positives: -low power consumption. It’s gonna be so inexpensive on your electricity bill. Only 10watts of power max! -stylish! The prefilters are very attractive I’m in a very modern minimalist space with black and whites and grays. The default pre filter it ships with fits perfectly! Diff decor? They have many different colors for you. I have to say, I doubted this thing for a bit because of its seemingly lacking power. It reminded me a lot of the Levoit Vista 200. However that model is awfully weak and not worth the money. I believe the reason why the Blue Pure 411 Auto works so efficiently well, is because it is 90% filter. There’s no plastic unibody or restrictive intake grills. Just fabric and filter. Because of this, less fan power is needed to pull in air through several layers of plastic holes and super dense materials. Pretty innovative and a true example of “less is more”. Highly recommend for those who want a stylish, efficient minimalist air purifier for a small space.
