Blueair Blue Max 3350i Smart WiFi Air Purifier, HEPASilent Combination Filter Up To 86m² Rooms Removes 99.97% Pollen, Dust, Mould, Bacteria, Viruses | Activated Carbon Reduces VOCs, Odours

Excellent value for money. I have only used the air purifier for a couple of weeks but so far I am very happy with its performance. It removes odours from cooking very quickly and the automatic mode is very effective.

This gives you a Air Quality score which seams accurate, auto setting kicks in when any contaminants are detected and lets you know how long it will take to make the air quality normal, I can feel less pollutants in the air when this is on, high setting is a little loud but clears the room quickly, night setting is whisper quiet, really happy with and and plan to buy 2 more for other rooms

I don’t understand why Blueair has so many negative reviews. For us, the Blueair 3350i is the only thing that has worked to a certain degree for my son’s allergies. It works quietly, and if you need it, 20 minutes on maximum speed really freshens up the air. We bought a Bosch, and it broke within months. We bought the famous Philips 3000i, but it didn’t do a thing. The Blueair 3350i doesn’t eliminate all the allergens, but it still does a far better job than either Bosch or Philips.

Here's the translated review in English: "I must say this air purifier performed beyond my expectations. Although the product was larger than I initially thought, this proved to be an advantage as it provides better air circulation. The weight is quite reasonable, and setup is extremely simple. When I first opened the box, I was concerned when I couldn't immediately see the filters, but then realized they were positioned in the side compartments. Filter replacement is very easy, and it's a big plus that the outer fabric layer is washable. Being able to wash this fabric during the recommended 6-12 month filter replacement period helps extend the product's lifespan. Being able to track filter life through the mobile app and access live support when needed are great features. It's impressive how it operates almost silently, especially in night mode and at low levels. Power consumption is also quite low. Even at high fan settings, it produces a sound similar to an air conditioner, but it's not disturbing. The only shortcoming I noticed is the PM 2.5 sensor's sensitivity seems a bit low. While cooking or sweeping the room, the sensor light stays blue (excellent), though it does respond to cigarette smoke and similar conditions. I think this sensor needs improvement. Overall, it's a successful product I can recommend to anyone who values their health and clean air environment. However, if purchased solely for dust removal, it would be difficult to claim it removes 100% of all dust particles."

Excellent product. Clears the air including the smell of weed and is super quiet

I bought an air purifier having moved into a flat near a busy road because I'm conscious that a lot more pollutants will enter my home. This air purifier lets me know exactly what's going on with the air quality, quickly filters out pollutants and let's me see a history of what's been going on. It's relatively inexpensive AND the app allows me to control when it goes on and off. In just hope now that BlueAir will bring it a smaller version for my bedrooms which is also app connected.

I have this in a loving room to help my son with allergies. Owned for almost 2 months now. Left on auto, and constantly reporting excellent air. Non-smoking house, unit is idle 99% of time. Now filter reports 80% used. Cost of replacement filter £50! Cost of ownership is therefore too high! After moving home, It refuses to maintain connection with the Wi-Fi, connects, then immediately drops the connection - it's a 2GHz connection and the AP is 20 ft away! This is probably one of the most disappointing, expensive and frustratingly badly designed product I have been unfortunate to buy. When I contacted the manufacturer to ask for a return, they gave me some narrative (which was well scripted) to ask me to wait longer - I think they know how uselessly expensive their product is.

Swapped this as had smaller 3250, however, could not obtain filters. This is larger but in my view much better and its easy to obtain filters. I have an Air quality monitor and this product matches the functions and notably cleans the air quickly. We have neighbours with log burners and at times it's like Victorian London thus invested in this to give us a chance from the dreaded PM2.5.

Design is not good, compared to other brands, Filter is directly accessible, covered by cloth cover. Grey part is just cloth. Air quality always shows excellent compared to my other product.

Not very good..found the air quality sensor not accurate..tested comparing to 2 other air purifiers when there was real smoke in the house..

The power won’t come on and customer support is not responding.
