BLUEAIR – Blue Max/Pure 3250i, Smart Purifier, Air Quality Sensor, HEPASilent Filter UpTo 48m² Room Removes 99.97% Pollen, Dust, Mould, Bacteria, Viruses|Activated Carbon Reduces VOCs, Odours, Grey

Bought this item thinking it would be easy to use it and change the filters. Very disappointed, 9 months later, I cannot find any replacement filter. The machine is not usable any more. Don’t recommend

It doesn’t detect any smell in the room and consequently doesn’t turn on in automatic mode. Update after 6 months: it completely stopped working and there’s no warranty.

Missing soft brush as mentioned in the demo 😰

This air purifier is lighter than expected, and it is very easy to use with only two control buttons. The design is also stylish, so it blends well with the room without disrupting the overall interior decor.

I love this. Having done a fair amount of research this came up the best of the bunch within my budget. It was so simple to set up and I certainly noticed a difference within a couple of days. I live near a buy road and have a neighbour underneath who smokes in the room underneath my bedroom so this is giving me both peace of mind and helping with horrible smells from the smoke. It appears to be quite sensitive, though less so if the tobacco smoke is milder, and will kick in mostly as expected if left on auto. It will even kick in if I am showering and using fragranced products and haven't closed the bathroom door (and my bathroom is down the hall from my bedroom). Looking at the app, I can see it turns on at various points during the day when the levels of pollutants in my room go above normal even if I haven't noticed anything. Very happy I bought this, even if I wish the 'Auto' mode was a little more sensitive to tobacco smoke. I have now bought a Mini-max one for elsewhere as I love the Max so much!

Product as described. Can get loud when air is polluted. App works fine. Simple and effective

Do not buy if you are in Italy - it comes with a UK plug. Customer service knows this. They should not be shipping to Italy.

I recently bought the Blueair Blue Max 3250i for my lounge area. I unit itself was a bit bigger than i expected but i have and open plan lounge/stairway so it is good for covering the entire area. I find it is working really well at keeping the air inside my house clean. It works well at getting rid of cooking smells. I was making breakfast one morning and i overdid the bacon which left the downstairs area smelling quite strong. Almost immediately the unit sensed the change in the air. The little light turned from blue to red and the fan kickind it on high, starting to clear the room of the strong cooking smell. Sometimes when i grill bacon the smell can linger most of the morning but about 20 -30 minutes of the unit doing it's job and the light turned back to blue and you could hardly smell any odours lingering at all. I'm glad i purchased this air purifier as it also seems to keep the polen at bay in the summer months much to the releif of my son who suffers from allergies. Will be buying the smaller Blueair purifier for my bedroom soon as this one does a fantastic job downstairs.

When the other half goes wild with the deodorant spray, the air sensors detect a massive spike in PM2.5 (tiny airborne particles that we cannot see). The little LED indicator light instantly turns red to warn us the air is dirty, and the machine kicks itself into high gear. The real test happens when I bring this machine near the kitchen. If we are frying up food using a pan or running the air fryer, this machine goes nuts. It doesn't just catch dust; it captures heavy grease particles, smoke, and cooking smells. Watching it ramp up to full speed the second the oil starts popping really shows you just how important proper ventilation is when you're cooking, and how much invisible junk normally hangs around in your house. Because this is the "i" smart model, it connects to your phone via Wi-Fi through the Blueair app. This gives you live graph tracking of PM2.5 levels, and you can actually watch the pollution spike when you use the air fryer, then watch it drop back down as the machine cleans the air. With the app, you can switch between Auto, Night Mode, or manual fan speeds right from your sofa. You can also set the purifier to automatically ramp up right around the time you get ready in the morning or start cooking dinner, and tell it to dim down into Night Mode when it's bedtime. When it comes to pros and cons, the whisper-quiet Night Mode is fantastic. It drops down to a virtually silent 18 dB and dims the bright control lights completely, making sleeping at night incredibly pleasant. The washable fabric pre-filter sleeve is another massive plus because it catches heavy dust and hair before it clogs the inside, and you can just vacuum it or throw it in the washing machine to save money. The only real downside is that if you forget to turn on Night Mode via the app or the machine panel, the LED air quality light on top is fairly bright it can easily illuminate a pitch-black room. You can reduce the brightness via the app to 0% which will keep it operating without any lights, but there is a chance you can forget its switched on! For the filter lifecycle, you don't have to guess when it's time for a replacement. The app tells you the exact remaining filter life percentage, and a dedicated indicator light on top of the unit will turn solid red when it's officially time for a fresh one. The purifier gives us peace of mind but wish I had more than one!
