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

This air purifier (3250i) is not small, but after downloading the app and setting schedules for daytime & night time operation, the running costs are negligible, but the best thing about this purifier is how quiet it is on auto mode, it obviously will increase the fan speed depending on the quality of the air, the night mode is ( unless you put your ear up close ) is really very quiet and did not disrupt my sleep.This has been running none stop for two months and certainly has made breathing so much easier, the cost is maybe a few pence a week.

Bigger than I expected but certainly does the job. The auto setting is great as the purifier kicks in when the air becomes polluted.The app is great and reports on air quality, filter use etc whilst also enabling you to control the device from the app. Would highly recommend

Who wouldn't want cleaner air?! This device is quiet on a low setting, but quite loud at full pelt. Since using it, my nose has been much less congested, so. It must be working!

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."

Keeps the air in the bedroom a nice neutral. Leave it on 1 all the time and noticeable when first entering the room that the air does seem cleaner.

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

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.

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.
