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.

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.

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."

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.

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.

Great purifier. Something i did not realize until nearly 6 months after having the purifier is that the night setting does not turn the lights off which i thought was odd - but i accidentally figured out that if you hold the button down for a few seconds it turns the lights off. Worth knowing if you don't like sleep disruption like me!

This product has too many cons to be worth it.1- the sensor is very bad, seems random if anything. I've put it in the kitchen (which has smoke and food smell) - sensor said: Excellent air quality. In the living room which was dusty and smelling smoke, also excellent. In the bedroom, which had been cleaned previous day and no smell at all, it was just good. And let me be clear, the reason I feel confident to back that is the fact that I have allergy to certain particles, like smoke, and my nose will block. My "own allergy sensor" and other people's sense of smell contradicted the device's sensor.2- I bought this because it was the only product claiming to remove particles over 0.1 micron and activated carbon, which is what you need to remove smoke. Others wouldn't. Therefore, I had slightly higher hopes for this. The results however were unsatisfactory. I won't say this is useless, it certainly has a filter which may clean the air a bit, but far from doing a great job. I tried in most rooms in the house, and it failed.3- WiFi and app features are unnecessary. Yes, it's fancy to see the results on the phone, but I bought this to have a decent filter, so it would have been better to spend the extra features on cleaning the air, not in an app.Overall, unahppy and now have a white elephant in the room which will go to the shed
