BLUEAIRBlue Max 3250i Smart WiFi Air Purifier, HEPASilent Combination Filter Up To 48m² Rooms Removes 99.97% Pollen, Dust, Mould, Bacteria, Viruses | Activated Carbon Reduces VOCs, Odours

Seems to be working very well. It's wonderfully quiet! Excellent for summer too as the clean air emitted quite cold, so it doubles as a fan in a way.

What can I say but absolutely fantastic quality with the extra action of being able to use your phone to switch on, adjust speed etc, clears and cleans your rooms with ease

Purchased 2nd one. I love these air purifiers due to being smart and better particle filtering than my previous 2 I have had for 4 years. I can defo sense the difference. The pm2.5 sensor works really well. Blow our a candle and as soon as sensor picks up the odour off it goes in to full clearance mode.This device is so quiet and I like the app. Don't hesitate whether you are new to air purifiers or upgrading

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."

Arrived well packaged. Very easy to set up, even installing app was so straightforward.I have put this in my living room near doorway which is permanently open and set it on auto mode. Immediately it’s saying that air quality is great with a blue light showing. It’s very quiet and do not notice any noise at all. The next day I bought a bouquet of flowers which I put in living room, immediately the purifier started working light turned green meaning that air quality was now down to good and fan started as well, noticeable but not loud, after about 20 minutes all returned to normal blue light and silence.Extra information, it does blow out cool air, found by accident in app settings that there is a slightly warmer mode perfect for winter.Have noticed that getting replacement filters might be an issue as most places are sold out currently, however they do last 6/9 months.UpdateHave now used this a few days and have noticed that when I have my wax burner on it immediately goes to red light and fan starts, noise is noticeable but not intrusive, after about 30 minutes unit returnsto blue.

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 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.

The hardware part is good, but there are some very bad decisions that destroy the product.1) There is a "Child Lock", but this "lock" does not affect the power button!!!So your child can't change speeds but they can turn it on and off at will.In Practice, there is no true Child Lock.2) You can control the brightness unless it is in night mode!!!So you can only turn the light off if you are NOT in night mode, if it is in Night mode the LEDs are Hard Coded to be on.3) You can control the speed unless if you want the quieter speed, aka "night mode"The product has more than the normal 1 to 3 speeds, you can have 9 different speeds between 1 to 2BUT you do not have those same options between 0 to 1, which is a lot more important if you want a quieter operation. AND the product can work in a speed between 0 to 1, the "night mode"So if you want to use it at night you have 2 options:Or you use "night mode" and the LEDs are ONOr you do not use "night mode" and the noise is greaterIn resume buy if you do not have young kids and do not plan to use it at night
