Title: A great budget purifier with AUTO feature!
Review: 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.

Title: Quiet, compact, effective
Review: As someone with allergies, I have had more than my fair share of air purifiers.This is one of the best, most quiet for single room use. I originally ordered a used air purifier, but it came with an off-putting smell.The lights on top are unobtrusive, but are less helpful than simply listening to the sound of the air purifier as you push the button, since there are no indicators with the lights.Aside from that, the unit sips electricity, is simple to operate, battles allergies effectively, but probably isn't worth the 50% price premium over the mini.

Title: Good for the size, quiet, instructions aren't helpful though if you can find them
Review: This air purifier is quiet and doesn't take up a lot of room. Small but powerful. Setting one is great for sleeping. I love that the outer filter is washable. It seems like the inner filter lasts a long time, too. After having this maybe 3 months the HEPA filter still looked really white and seemed there was no dust on it at all, and I was running it all night every night (on setting one). Now I use it in my office at my new place and run it all day on setting two. Not sure how long the filter will last on 2, but the replacement filters are not too expensive.The company is in Sweden and apparently there is no way to contact them. They say "Contact your local retailer for questions" which is basically Amazon! I bought the mini air purifier and it came without instructions, or maybe I lost them. Because somehow I knew there was a child lock system. I tapped on the fan icon and the fan setting wouldn't change. I held it down and it didn't change. Sometimes it turned off. Apparently there is some kind of child lock on it. I tried holding the on/off button for 5 seconds to unlock it and at some point I accidentally turned it up from fan setting one to setting two (which I was happy about, because one wasn't doing enough).Later I somehow accidentally turned the child lock off, I guess, because I was miraculously and thankfully able to easily change the setting from 1, 2, or 3 and back again. I just hope I don't lock it again. Between this and my washing machine lock getting stuck this month I'm fed up with the child locks! Make some items or optional models for people without kids at home! Or at least make it easier to turn the child lock off or post some actual instructions on the website.

Title: The best air filter on the market
Review: I have purchased multiple air filters to control, allergies and other bits of particles in the air That two of my family members are sensitive to. I purchased my first one three years ago and it still works as well as it did when it was new. I bought a second one recently from Amazon and it’s exactly the same quality, easy of use quiet, and genuinely changes the quality of the air, removing all of those particles. This is the only air filter I will ever buy in the future, having tried other brands. They don’t measure up to the quality of this one, not even close. I would recommend anyone who is looking for an air filter buy only this brand. Any other product will be a wasted your money and you’ll end up replacing it in a year

Title: Quiet Little Purifier
Review: So far, this BLUEAIR small purifier is working well. The air in the bedroom seems to be cleaner. It is quiet and does not disturb our sleep. In the future, we will get a couple of others for our guest bedrooms.

Title: Small but works!
Review: I bought this small air purifier based on a NY Times Witecutter review. I use in my bed room and brought to the kitchen when cooking. It works! No cooking smells! It’s small and price friendly but really works.

Title: Perfect for baby
Review: Some reviews state the fan can be loud, but we actually prefer it on high because it creates enough white noise to soothe and relax the babies. First time we went to clean the filter there was a ring of dust around the unit so we knew it was working overtime.

Review: I love this bedroom sized air purifier from Blueair! The controls are easy to use and logical, the white produced is something I enjoy as well, of course can adjust speed to reduce any noise if you wanted to. I was able to pull out of the box and use within minutes and the sleek simple look makes me comfortable to leave it out in the table full time.

Review: March 22, 2023, I am so happy I bought this BLUE Pure 411 Auto air purifier, just wish I had years ago! Full disclosure, I have severe indoor and outdoor allergies year round, post nasal drip and I have asthma. Needless to say I usually spend a lot of money on tissues, allergy medication, sinus rinse supplies and have to remove dust from my home daily and launder bedding every 3 days.Already I can breathe better, no coughing/wheezing, wake up with clear sinuses and haven't even needed my allergy meds! It really clears out airborne odours (food/farts/sweat) and dust. It makes a huge difference for air quality especially when I am sleeping, no more snoring from plugged sinuses. I like the sound of a fan as it buffers noise from outside traffic or loud music/voices. So, I don't find this loud at all, even on it's highest setting and it's always on high 24/7.I will update this review in 6 months and add further information based on my experience but so far it simply amazing and affordable!****UPDATE!***July 20, 2024 It's been a year and three months! This little machine is a beast! I keep this one at my bedside. I have had it running on its highest air purifying function 24/7 since the day it arrived! It is only off while changing filters. I absolutely love it and when it is in stock I highly recommend buying it! I will be buying more of them for other rooms. I change my "inner round accordion " filters every 3 to 6 months. I do recommend having extra filters both inner and outer just make sure they are for your specific machine. I have found that the non blue air versions of the cloth filters often do not fit well and some are made of materials that blocked the air purify function/suction. I did recently purchase a two pack of "inner" filters that are not "blue air" brand and they do fit but I will update in 3 to 6 months and let you know if they are good quality or not and provide the brand of the ones I bought. I do not think they are as good as the Blueair brand so far....I can see through the inner black part of the filter and that is not a good sign as large particles of dust and everything else smaller will be going through it instead of collected so don't believe they are real hepa filters.I do find that the "red" light feature that indicates the filters need to be changed is not reliable so I simply make note on my chore calendar to change the filter. I have also noticed that the outer cloth filters need to be cleaned much more often. You can easily do this by vacuuming them with a hand vac or a shop vac. I have a lot of allergies to dust and asthma so I do clean mine every day or two with a quick vac of the hand vac and I either hand wash it or machine was it every two weeks by slipping it into a mesh lingerie bag and just toss it in with a load of washcloths and towels.I will be curious to know how well this machine works as we enter into Summer "forest fire season". I will continue to provide updates with my experiences with this BLUE Pure 411 Auto air purifier! Take care and happy shopping!

Review: This arrived after 2 weeks, only to be equipped with a US plug, totally unsuitable for UK homes. No where in the description does it mention that this is the case. Avoid if in UK.
