Blueair 411+ Air Purifier: Compact Size, White/Diva Blue/Dark Shadow Color Options

Shan: Nice quality product. Small size good for small rooms. Little bit of noise at top level but not distracting. The air feels cleaner and free of odour. Would recommend this product

DT: This purifier works as described.
It's pretty quiet. When the fan speed is medium it doesn't disturb sleep. At first I used level 3 to start with during the day. At night lowered the speed to 2. It was not disturbing to sleep. The outer material filter supplied works well at catching larger dust particles and easy to clean with the vacuum. I would recommend this for a room size like a bedroom . Very satisfied.

Ben: I really like the 411 and 411+ Blueair air purifiers. I bought a 411 a year ago and it has been on pretty much non stop in my kids bedroom for the past year. I picked up two 411+s this week and I do think think the 411+ is a nice upgrade, but honestly I was perfectly fine with the 411. The 411+ is a little bit bigger, but it is more powerful and feels higher quality with moving the filter to the interior and having the mesh frame on the outside. The top screwed on the 411 and my kids would sometimes knock it off. The 411+ doesn’t seem to come off the same way and the filter is inserted from the bottom. The light seems to go completely off on the 411+ even though the website says it dims to 10%. Maybe I’ll have to check again in complete darkness with my eyes adjusted but I can see the regular 411 dimmed in daylight. I can’t see it on the 411+. I’m guessing they did this to correct complaints that some people had with the 411 (which frankly I think is quite petty - it gets pretty dim).

I’ve had Alen, Rabbit, Airmega, Holmes and probably other brands that I forget. This is the one I prefer for my kids bedrooms. I’d go with something larger for a big master bedroom...

MovieGuy: I have allergies, so I've been using air filters for over 20 years in my home. And I've probably gone through 10 or more air filters. For a lot of years I used a big Honeywell filter, which back in the day was often recognized as best-in-class, but as my 3rd of those eventually died (they lasted a long time!), I was ready to explore other types. I mainly got this because Consumer Reports gave these top marks. Now I have 4 of them (2 211's and 2 411's) and I'm very impressed!

They are relatively quiet (depending on the setting) and move a good amount of air. I really like how the filters work. The "blue" equivalent of a "pre-filter" is a washable cloth that you drape over the outside. Rather than constantly buying new pre-filters you just throw em in the wash on gentle/cold and you're good to go! The inner-hepa filter is something that just locks in place. It's very easy to replace and the price is comparable with other air filters.

It's difficult to really evaluate how good a job of filtering the air it's doing, so I leave that to places like Consumer Reports, but I'm very happy with mine (obviously... since I bought 3 more after my initial purchase) and highly...

Christina: Best purifier Ive ever had. Tried Bionaire, Honeywell etc. Not much noise, works (ive noticed a reduction in dust and improved breathing when sleeping). I bought two more units for other rooms after this one!

UncleBig: It's obvious even before you plug it in. Solid, precision unit. Efficient thoughtful design. On low setting it is not even audible in the bedroom yet the air exchange is noticeable especially if you have allergies. On medium setting it might come close to drowning out spouse's snoring. On high setting the sound is no different than an overnight flight to Hawaii. White noise at its best.

Felix Pennell: This is a high quality product. It feels and looks premium and level 2/3 sounds like a white noise machine, making it easy to sleep. I just wish the lights could fully turn off. Apart from that, very happy with this purchase and would definitely recommend it over other cheaper alternatives.

SF: Have been using this device for 2 weeks and my nasal congestions have decreased markedly. I have not noticed disturbing noise when running in low during the night, unlike many reviewers who have complained about it. The noise when running in higher speeds is similar to that of many desk fans. However, the one-button takes a hard time to be get used to, many times it's a hit or miss action. You have to cycle through all speeds for any selection you want: to turn it lower from medium speed you have to high-off-low. The must aggravating issue is that the indicators emit white light, even when dimmed. White light includes the blue light spectrum that is known to affect sleeping and you can decrease in any screen (laptop, tablet, phone) but not here. Have to use a folded post-it note to mask it, since it is running in the bedroom during the night and I noticed it affects my sleeping quality.
Worst thing of all: I sent 2 emails to the Customer Service site asking for clarification on the user manual recommendations. Two weeks waiting for a reply, still nothing. The phone number to call is a waist of time: more than 10 minutes on hold, so I desisted. Just hope I don't need to claim my...

Amazon CustomerAmazon Customer: I wound up buying two of these, one for each room. It seems to work great keeping the air circulating and I feel safer when others come into the room. I keep it at level 2 and it isn't too noisy. 1 you can barely hear and 3 is def noticeable. I put two round binders into the grates at the top, and attached a bungee so I can lift it and move it back and forth. I put it in high traffic areas when people have come and gone and move it out of the way when it is quiet. Works great and keeps me from having to touch the "sock" filter on the outside (which may have covid droplets) and keeps it from sliding the sock around. I highly recommend this item. Replacement filters are priced reasonably, and it is lightweight and mobile. The bigger unit which could have done both rooms has costly replacement filters and doesn't give the same peace of mind. (Would have had to leave the door open to move all that air-now I can close it and each room has it's own unit.)

mfc: We got this during the great Oregon wildfire season of 2020. For about a week our Air Quality Index shot up over 200 and even hit around 600 for a brief period. That is really bad air. We received the unit on Thursday just before the rains came on Friday night. I must say, it produces some very clean and nice smelling fresh air. I checked consumereports.org and wirecutter.com for reviews on this product and they both rated its big brother (the 211+) very highly. This 411+ unit is also very good too IMHO. For a bedroom it is perfect. What really got us is how quiet the unit is on the low setting. You aren't even sure its running. The only (slight) complaint is the LED light on the low setting is a little too bright for sleeping. Too fix this, I covered it up with some opaque tape. The tape let enough light thru to be able to tell the unit is on. Second, according to the reviews, this unit works well in filtering the air at its low setting. You can smell the fresh air after you first turn it on (on low). We are very happy with it and ordered a second unit for the other bedroom. We also tried running it in the living room on the high setting during the day. It seemed to cover the...
