Good, loving it
This is a 5th day review. I was looking for a airpurifier for my home and been in search for couple of week. My friend have a same model and he also suggested. It's just hard to find this model in amazon while on search, even with the model number. I was looking for some other brands and get to know about this. While looking on the website, blueair have a dealer for dubai and located in karama. Bought it from amazon at 2000 on prime day, and dealer doesn't have a deal or offer, they stick at 2500. Even it goes down to 1850 on prime day time, but 2k for me. Good packing, and nice look. While on starting showirng around 56 as my room level and easy to use with app and track all details. Not much noisy even with 3 speed. While 2 speed a coled air flow can feel from it. It have 2 wheel in the bottom for the easy movement and coming with square and round plug top. Both sides have the pre filter. Touch is very sensitive. Mostly using with the app.

Ok so i was firstly amazed how it could deal with smells, from my mothers awful midnight burning of her toast. to our elderly dogs toilet in the hose. it dealt with any smell within a minute or so. and thats pretty much were the positive end. the fan is no where near as powerful as it should be ie, it was in my room which is around 15ft by 7ft, and i couldnt feel it when i was n my bed even when i had the fans at full blast. which is really bad given how hot it became this year. you have the coloured led's which as far as i can tell , has no explanation at all in the manual or their website. the app tells you about all this details ie number and bacteria and virus, but doesn't give a explanation as to what it means, and doesnt give you any control over them either. it never gave me any control over where we actually were, and it insisted we were about 7 doors down. and because there were no warning of any kind about the filters being blocked ie the level of dust, no once did i think about checking them.... right up until i returned the device to find both filtered fully clogged with dust. which in a way is impressive to see what it collected, but then you realize that it didnt do what was advertised which is enable the whole room ( an amount of space far bigger than my room) to ensure a much healthier environment, and yet i knew there was dust, dog hairs floating about less than 5 ft from the device. in the end, i couldnt bring myself to keeping this £500+ device, that didnt do what was advertised and because the filters were clogged, it would end up failing to protect. so i had to return it and buy a £15 fan.

Suspected return. The filter inside wasn't wrapped in plastic as the handbook says it should be and once I turned it on, the filter started at 86% left. Doesn't filter gases despite being on maximum fan speed in the middle of the room. The LED is stuck on orange and the app says the air is polluted. It is from cooking. After the evening meal has finished, it still hasn't cleared the gases it says are there. We've since learned that opening the window for 5 minutes is more effective than 2 hours of this machine working. I will have to get a different product as I do not trust this to keep me sane during pollen season.

This is a top range air purifier. Probably the best in the market at the moment. It covers up to 62sqm so definitely a big room or open plan. We use it on the ground floor and it cleans the air through the whole kitchen, dinning, hallway. Although it is a big device,it looks stylish and elegant. It is very easy to set up. Just place the filters, remove certain plastic covers and plug in. It sort of does the rest for you really. This air purifier has everything you can possibly need. It uses filter to clean a variety of contaminants such as pollen, dust, pet dander, mould, bacteria and viruses with its so called GermShield Technology. Its control panel is easy to use and manange, thanks to its colour coded system. This system tells you the quality of the air through. We normally set it on auto. Sometimes the reading shows no pollutants so it doesn't need to work,other times (if we've cooked, if there's barbecues in the neighbourhood, or we've had the door to the garden open etc.) it goes from yellow up to red, which means severe/lots of air pollutants. Even when on red after about half an hour to an hour it will bring it down to zero again. It sort of produces cool air as it cleans and circulates it. It's silent and quiet, you wouldn't expect it from this size. Has a mild humming which is actually quite soothing. I find it incredible that it can detect things like viruses. On auto mode it adjusts how fast the fan needs to work. But you can change it. The app is great as you can see all the data there. Ideal for people with asthma or allergies or if you want to use it preventatively. It can cover a high square footage, so it's ideal to put in big rooms or offices. It will tell you if it needs a filter replacement. It also claims to use less energy than other ones due to its smart technology. The company offers 1 year warranty which can be expanded to 5 if you register the product and follow their instructions.

I have suffered from hay fever for years, with constant sneezing every day and then associated coughing. I have tried eye drops, which work perfectly well on the eyes but the rest of the body was at the mercy of the pollen. Therefore I thought I would give an air purifier a go. This one, which is available at for 862 pounds on the website of the product (I mention this as Amazon is not currently showing the product as available via Amazon), is certainly expensive but it is clearly a gold medal purifier. My hay fever showed a marked improvement after a day of using it and my wife, who suffers from asthma, is hopeful of having a similar reaction. The purifier is of a good size and I found a perch for it in the corner of my house, with it being a conversation piece when people first see it: ‘Oh my, what is that, is it a Dalek?’ Personally I think it more resembles a robot from Blake’s 7, but I can see the point they are making. Once this is switched on the sound really is very minimal, with it giving off a barely discernible buzz in the background as it goes to work. I stuck it on auto and immediately saw it give off a light blue light which means the air quality is good. Then, about 30 minutes later, it sprung back to life with the light changing to red, indicating bad air. Two minutes later, with it giving off a blast of cold air, the blue light returned. This beauty is going to work superbly in the summer, as the cold air is so refreshing. As a result I think it doubles up perfectly well as a mobile air-conditioning unit. When you put it onto maximum it is reasonably loud, although you can still hear the telly and have a conversation with it on. Anyhow, you will not really need it on maximum as auto prods it into life throughout the day. One thing I should mention is that it was really easy to get going, you simply plug in the plug (both an English plug and a two prong one were provided) and away you go. Once going it is easy to operate, both manually or via your mobile smart phone. The wheels on the bottom of it make it easy to move around the house and I could certainly carry it up the stairs by myself. I found it handy to take to different rooms, to see where the dust was. You could get a couple I suppose to save yourself the bother but, once done, you can leave it in the room that gets the most use, generally the living room. However, saying that, I will definitely move this into the bedroom when the temperature heats up as it will make sleeping so much easier. I must say that this is an absolutely outstanding product; sleek, well-made and superbly engineered. The best Swedish export since Perkele (a band).
