I recently got the Blueair Blue Pure 511i Max Air Purifier for my home, and so far it’s been working great. Right out of the box it was easy to set up, and after running it for a few days I could tell the air felt cleaner and fresher with less dust and airborne particles floating around.One of the strongest points of the Blueair Blue Pure 511i Max is how quiet it runs. Even on moderate fan speeds, it stays unobtrusive — perfect for bedrooms, living spaces, or any area where background noise matters. It uses Blueair’s HEPASilent technology to pull in air from all around the unit and effectively capture dust, allergens, smoke particles, and pet dander. It’s designed to clean up to around 926 sq ft of air in one hour, which makes it a solid choice for larger rooms or open floor plans.I also appreciate the filter performance — it feels efficient without feeling like the airflow is restricted. Although it’s compact, it doesn’t feel like a small unit; it feels like it’s doing meaningful work when it’s running. Several friends I’ve recommended it to have noted reduction in odor and pollen after a couple days of use.In short, if you’re looking for an air purifier that’s easy to use, effective, and quiet, the Blueair Blue Pure 511i Max is worth it. I’ll update with photos and a short video soon once I’ve had more time with it, but so far this has been a strong addition to my air quality setup.

Blueair Air Purifier was the one I chose because it uses original HEPA filters, along with the strong reviews I read on Amazon and elsewhere — and I am extremely happy with our purchase. I placed it in a room filled with storage boxes that had a musty odor, and it completely eliminated the smell. It runs very quietly, and I truly believe it helps remove dust and allergens from the air. I purchased it during Prime Day and received a great discount, so I’m very pleased with the price as well. If you’re looking to bring freshness to any room in your home, I would definitely recommend Blueair. It truly delivers.

It's really nice to have, bigger than I expected, but that's even better. It works nicely, and I enjoy having a way to see the air quality on my phone. I used to always get a runny nose due to dust in my room whenever I cleaned, but this has helped me not get as many runny noses anymore. I can see very little, if any, dust in the air (like when you see it in the sunlight). I tested it by blowing out a match in front of it to see if it really detects stuff; it went to max fan speed, which makes me believe this is working. Speaking of fan speed, it's really cool and nice to feel; I honestly replaced my AC with this most of the time. The main reason I would not give it 5 stars would be the lights. I hate sleeping with any type of lights, and whenever I change it using the buttons, it sometimes leaves a light on even in night mode, which in turn I would need to fix by going on the app, which allows me to turn it off. Other than that, the air feels very fresh, and I can hardly smell anything; it feels clean and nice in the room I use it in. It does need to be connected to an outlet instead of battery, which makes it hard to put it in the middle of the area without a cable being in a way, but for it's price, i would say it's really good, the filters aren't too expensive and I would only need to replace them once every 6 months based on how much im using it.

So far so good, first day. Easy set up. Unboxed and plugged in. Easy buttons and instructions, took one minute to figure out. Love the air quality light on the front that changes colors. Has three fan speeds, automatic setting and a night time mode. Not terribly loud on high, sounds like pleasant white noise, actually like it. Cleans the air super fast. I have allergies so this is awesome. It has an app that tells you when you need to buy a new filter which is super cool (every 9 months). You can also control it from your app. Like it better than the ion ones. I got this one because of the excellent reviews online. And it gets rid of mold with a proper HEPA filter, better than the cheap ones. I bought two of these, one the bedroom and one for the main living area. I'm suspecting mold in my hvac system and bathroom. This is giving me peace of mind while I wait for the testing company. And I'm already breathing better hours later and so are my cats. I needed this anyway. Highly recommend.

Casi no hace ruido, funciona perfectamente. Lo recomiendo.

Love the look of it. Fan is quiet. Shows the air quality on the app. Only one I found that promotes cleaning the air of mold.

Works great and even on the highest setting is pretty quiet. Seems to help keep the allergies down and there is less dust. Removes kitchen smell extremely quickly and the sensor seems pretty sensitive.Easy to change the filter and replacement ones you can find third party sellers. Very happy with the unit.Only slight issue is wonky app.

EL PURIFICADOR ES UN EXCELENTE FILTRO DE AIRE. YA QUE PURIFICA EL AIRE DE TU ENTORNO. IDEAL PARA GENTE CON ASMA Y/ O ALERGIAS. MUY RECOMENDABLE

No sé si puedo recomendarlo. Si se encuentra en modo automático casi no se siente el flujo de aire entrar y salir, aunque es evidente que hay polvo en el cuarto donde está ubicado. El prefiltro está muy limpio a pesar de haberlo usado diario durante más de un mes. Leyendo me di cuenta que detecta solo PM2.5 que aunque son las más partículas más graves, al no haber ese tipo de contaminación en la habitación , aunque haya polvo u olores el sensor no se activa para que funcione con más intensidad cuando está en modo automático. Vivo en una ciudad contaminada y checando los registros mensuales según este purificador la calidad del aire interior estuvo excelente en el 98% del tiempo. Cuando registró algún pico fue porque apague una vela justo a su lado y ahí si entró el sensor, lo que me dio idea de que no está dañado, simplemente así es. Si lo quieres para filtrar polvo no lo recomendaría. Comparo con otros purificadores que tengo en mi casa y a los cuales constantemente tengo que estarles limpiando los filtros y éste no se compara.
