Small, but effective
I put this in my office where the air always felt kinda stale. Within a day the room smelled cleaner and less dusty. It’s quiet on the lower setting, just a soft hum. The only thing I’d change is the power button is pretty sensitive and not extremely clear how to use. Not a big deal though. Good little purifier for a small space!

I’m REALLY impressed with this
This Blueair air purifier is pretty amazing. I should preface by saying my husband and I are both indoor vape users. I was worried an air purifier wouldnt be effective because of this fact. Add in that we have two large dogs and 4 indoor cats. – Blueair proved me wrong.So I bought this unit in May 2025. It’s now the 20th of November and the filter JUST turned red promoting me to replace it!!! Holy cow! That’s an amazing value and effectiveness!! It made a huge difference this entire time with lowering the smell of dog and indoor air pollution I could constantly smell in this home of ours.We have an older home with fixed windows, add in the 4 indoor cats and the inability to leave the doors open to let in fresh air regularly thanks to the constant Florida heat and humidity, and I was always feeling like the air was just stale and gross in here, even before the vaping came into account. But this air purifier has been a game changer. It was so easy to set up, so easy to maintain and clean (both regular maintenance and with washing the exterior cloth filter) and replacing the interior filter took no time at all.Highly recommended product!!

It’s new, working, silent, looks good, and I feel like I’m breathing better.
Simple to set up. Works fine. I’ve only had it for a few days and will put up another review after I have changed the filter in about five months. I’ll be able to see the dirty filter and know how well it keeps my room dust free. The air here many times is loaded with dust from the desert winds when they really pick up.

Difficult to understand use, no clear on and off
I like the effectiveness of this air purifier so as far as performance goes, I think it should have five stars. Since there’s no way of testing air quality and we just have to go on faith, I’m guessing that it’s a good quality machine. However, clearly it was designed with aesthetics in mind and not practicality. It’s difficult to turn on an off or to know how to turn it higher or lower. You do this with a series of taps on the top ring. It’s very Star Trek in a very unnecessary way. I love Star Trek. I love everything about Star Trek. I don’t think even they would’ve kept this on the enterprise because it’s too annoying to use , however, having said that I just turned mine on low and keep it on all the time. I have noticed that environmental allergies bother me much less this year. If you are into the super modern look and have the gray walls that all designers think everyone should have now, you might love this look and usage facility might not bother you. I don’t think an older person would be able to use this easily. The only thing that lets you know if it’s on or off is a light that shines for a moment when you tap it. There is delay in the action so you don’t know if you’ve actually turned it up higher or turned it off for a few seconds, so if you’re impatient like me and tap it again, you’ll probably accidentally turn it off and have to start all over again . Again, weird design, leaving you confused. Is very silent and that’s a big plus. It probably deserves one more star, but I’m too annoyed with the lack of the on and off clarity to increase my stars. Here’s an idea, how about somebody make a vintage looking air purifier with simple on off switches, make it look like a vintage radio. I bet that would be a big seller, the nice old-fashioned knobs. On and off.I have no idea how I’m going to change the filter when it’s time to change it, the whole thing is a mystery as to how it’s assembled, and I wish they would just include a few extra filters with the purchase so then you weren’t trying to figure out what kind of machine you have and which kind of filters to buy six months later. I’d be willing to pay extra to have the extra filters delivered with the purchase. If I sound annoyed it’s because I am. But I’m sure the machine is good quality.Updated review 9/11/24: The machine is actually silent on low. It’s been on all day and I didn’t even know it. You literally cannot hear it at all on its lowest setting. It also did a great job getting rid of a smell that was from something burned in my kitchen. So it is a very effective machine. I also now am wondering if the thing that I found fault with is actually a benefit to older people with arthritis if they cannot turn a knob, then just tapping the top might be very helpful to them. In fact, anyone with mobility issues could put this beside their bed and just tap it at night in the dark and it would be easy to use for them. Because it is silent, it will not work for you as a white noise machine. I’m now going to add a star. Xo

Works great for dog allergies
Absolutely love this air purifier. My husband learned that he was allergic to dogs when they started living with us and so I got one of these and one of the bigger ones and he has no problem breathing now! It has definitely kept allergies out of our house. Cleaning the fabric filter is not super fun but is pretty easy.

Cleared My 10′ x 12′ Office of Very Musty Air
Works great. Quiet. Easy set up and operation. Got it for a 10′ x 12′ office with very musty boxes. Cleared the air of that smell and nastiness. Breathing easy now.

Buyer beware!!! Horrible customer service
Disappointed in BlueAir Warranty Support – Buyer Beware if Outside the U.S.I purchased the BlueAir 511 in late November on Amazon.com. It worked well initially, but within six months, the power adapter failed, and the unit stopped working. Since the product comes with a 1-year warranty and was sold by BlueAir and shipped by Amazon.com, I expected the issue to be resolved quickly and easily.I submitted a warranty claim, and everything seemed to be moving along—until I mentioned that I live in Bermuda. From that point on, all communication from BlueAir completely stopped. I followed up multiple times with no reply. I even called and was told the issue would be escalated and that a supervisor would contact me within 24 hours. It’s now been over a week, and I still haven’t received a response.It’s incredibly frustrating to be ignored after following all the proper steps. If BlueAir refuses to honor its warranty simply because of where a customer lives—even when the product was purchased through official channels—then that should be made clear upfront.I’ll be sharing this experience wherever I can to help other potential buyers make an informed decision. The product may be good, but the lack of accountability and poor customer support is a serious red flag.

Le but de cet achat était initialement destiné à purifier l’air de ma chambre l’hiver, lorsqu’il fait très froid et que les fenêtres sont collées, ou à certaines périodes du printemps, lorsqu’il y a trop de pollen dans l’air pour pouvoir aérer.J’ai reçu cet article parfaitement protégé et avec un emballage du fabricant que j’ai trouvé astucieux.Une fois reçu, j’ai immédiatement mis en fonction ce purificateur d’air, afin de vérifier s’il était en état de marche.Mise en marche :Grâce au mode d’emploi redirigé aussi en français, la mise en marche s’est faite facilement. Je suis satisfaite d’avoir pu lire les explications dans ma langue (je suis francophone).En appuyant une fois sur le bouton situé sur le dessus, c’est le mode silencieux pour la nuit ou le repos; en appuyant deux fois, c’est le mode normal; en appuyant trois fois, c’est le mode à toute puissance.Observation de ce processus :Il n’y a pas de bouton qui semble s’enfoncer, donc parfois je frôle le dessus et je parviens facilement à changer de mode, parfois il faut davantage appuyer. Je n’ai pas réussi à comprendre où se situe le « capteur » s’il y en a un. Ce serait le seul point négatif que j’aurais à signaler.Pas de télécommande pour ce premier prix, cela me convient parfaitement pour ma chambre. C’est suffisant pour mon usage.Résultat de la filtration :J’ai laissé fonctionner le purificateur environ 1h ou 2h (durée au hasard), puis je suis retournée dans ma chambre. C’est incroyable la sensation de frais que j’ai ressentie! J’ai senti immédiatement la différence, au point que j’ai décidé de m’en servir encore dès maintenant (pas uniquement pour l’hiver), tant j’ai été contente, ravie et impressionnée du résultat.Usage en mode silencieux :Bien que je sois très sensible au bruit en général, j’ai dormi plusieurs nuits avec le purificateur d’air en action en mode silencieux. Et cela s’est très bien passé, à ma grande surprise.Mon confort respiratoire s’est nettement amélioré grâce à cet appareil.Autres modes :Le mode normal est supportable en journée, mais peut-être pas de nombreuses heures consécutives si la personne reste dans la pièce. Très bonne efficacité rapide.Le mode en toute puissance est très bruyant, donc à utiliser lorsque c’est temporaire. Personnellement, je l’ai utilisé lorsque j’ai changé mes draps pour les laver, tout en ayant aéré avant ou après. Si je l’utilise, je ferme la porte de la chambre.Par contre, bien que je sois ravie de mon achat, j’ai faussement cru qu’il y avait un affichage de la qualité de l’air avec un voyant lumineux. Je me suis mélangée avec les photos que j’ai consultées. Donc il serait souhaitable d’indiquer qu’il n’y a pas de télécommande, ni de connexion avec le téléphone, ni d’affichage de la qualité de l’air.Cet appareil me convient parfaitement, à ceci près que j’aurais peut-être préféré investir dans le modèle juste au-dessus qui a le voyant de la qualité de l’air.Conclusion : Je suis très satisfaite de mon achat, en dépit de la difficulté que j’ai parfois à savoir appuyer correctement sur le dessus (j’y parviens toujours). Selon notre budget, nous investisserons possiblement dans un second modèle de cette marque spécialisée, qui aurait un voyant indiquant la qualité de l’air. Je dois préciser quand même que j’ai choisi cette pour ses « compétences », et ce modèle parmi la gamme selon la superficie de ma chambre et le prix abordable du Vendredi fou.Bref, merci à la marque d’exister au Canada. Soyez bien alertes sur les comparaisons de modèles.Enfin, je dirais que ce modèle serait parfait dans une chambre, que ce soit pour un enfant ou un bébé ou des adultes, ou bien dans une petite pièce destinée au télétravail. Bon magasinage!

Works great we smoke and it cleans the smell up

Easy to removed old one and replace with brand new.

First off, the design? Sleek and minimal—fits right into any room without screaming “I’m an appliance.” The three-stage filtration system is like a superhero for your air, sucking up dust, pollen, and even those sneaky pet dander particles.Setup was a breeze; I was up and running in no time. It’s super quiet too—no more background noise that makes you feel like you’re living inside a jet engine. Plus, it’s energy-efficient, so your power bill won’t skyrocket.In short, if you want your room to smell like a fresh breeze and not like last night’s takeout, the Blue Pure 511 is definitely worth the hype. 10/10, would recommend.

I am hoping that I do not have to use this for at least 6 months. So it arrived on time. yesterday, package was new and it arrived before I got the air purifier itself which just arrived this afternoon. Being that it is the manufacturer product, I would assume it will fit no problem and it really all depends on how well the air purifier I just received works. If the air purifier does not seem to be doing its job then I obviously will be returning both packages together. If need be will update in a week or so. I simply ordered this to have on hand when the need to replace the filter arises.
