Blueair air purifier 3210 Cleans 183 sq. ft.Filter change Indicator Unique HEPA Silent technology combines 2 filteration technology kills bacteria and virus Activated Carbon absorbs chemicals - White

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.

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.

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.

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!
