    Product Overview

    If odours and dust get on your nerves, you’ll love this air purifier from AEG. It’s designed for medium-sized rooms up to 38m2, leaving the air in your lounge as clean and fresh as a coastal breeze. With a minimum noise level of 17dB, it’s really quiet too. This model also comes with 9 speed settings, so you can either have it on low as you’re going about your business, or crank it up high when the dogs get back from the park. Whatever you decide, the smart monitoring feature is always on hand if the speed needs adjusting – which it will do automatically if it senses the air quality is poor. And because AirSurround tech creates a spiral movement that covers the entire room, there’s nowhere for even the tiniest particles to hide.

    Features we love

    Fresh air without lifting a finger

    AEG’s unique PureSense technology keeps an eye on the air quality inside your home, then will automatically make adjustments if it needs to. It uses sensors to measure the temperature, humidity, light and particles in the room, giving you an air quality reading you can check via the handy display or Wellbeing app. So, not only are you always kept in the loop, but you won’t have to lift a finger if the lounge is a bit stuffy.

    Powerful filtration never misses a spot

    Even the smallest of allergens won’t stand a chance against the powerful 5 stage filtration system. The pre-charged ultra-fine filter traps up to 99.5% of particles as tiny as 0.3 microns, as well as harmful gases and odours. It also eliminates up to 99.9% of bacteria*, keeping the air in your home as fresh as a daisy.

    *Filter media coating exhibits an antibacterial rate of up to 99,99% against E. coli, Staphylococcus aureus, Serratia marcescens and Legionella pneumophila based on external test according to Chinese standard GB 21551.2-2010.

    Smartphone app keeps you connected

    Thanks to AEG’s innovative Wellbeing app, you’ll have all the info you need right at your fingertips. From controlling your purifier and scheduling events, to checking the air quality and status of the filter, it’s easier than ever to stay up to date – even if you’re not at home.

    Circulation system reaches every corner

    No matter how big your room is, the clever AirSurround system ensures no stone is left unturned. Because it circulates the air in a spiral movement, it can reach every nook and cranny so there’s nowhere for pollutants to hide. And thanks to the filter’s large surface area, it can clean even more air for faster results.

    Quietly and discreetly purifies your home

    With a minimum noise level of just 17 dB, you’ll never have to worry about it drowning out your TV. In fact, it’s so discreet, you’ll barely notice it’s there. And even when it’s working hard at the maximum speed, the noise level only reaches 46 dB, making it quieter than a dinnertime conversation.

    Seems powerful and can be silent when in Smart mode, which I like. It’s a bit bulky, hence why I removed a star, but overall it’s very easy to use. I would have loved if it had a cover on top for when not in use. I need to improvise something to protect against my toddler.

    it's good, but yet disappointing...

    good and quiet, but useless app as it doesn't work well with Google Home. And not at all with Alexa.

    Okay, but not HEPA

    Product is ok. Stylish, easy to set and use. Has a lock setting. Filters may have a longer life than others. Cons: The app can't see where I live so the Outside is 30miles off. It's not HEPA. It's not cheap. Ionize technology release ozone (and the app doesn't check for it).

    Dramatically improved the air quality of a smoky with immediate effect.

    I am extremely impressed with this product. It has made a significant difference to the air quality of a smoky room. As a non-smoker, I'm particularly sensitive to the smell of cigarettes, so my partner is banished to smoking in just one room at the top of the house. Prior to getting this product the room always smelt stale and the smell of smoke would often creep down the stairs. The atmosphere in the room is now much cleaner and fresher and it has also totally eliminated the problem of smoky smells spreading to other parts of the house. This isn't a small product but the design is so slick and stylish that for me, the size is not an issue. I love the colour coded air quality feature. Another plus is that the air purifier quiet and easy to operate. I must admit, I'm not a big one for reading the instructions, so was pleased that operating this product is easy to work out! Highly recommended, especially for smokers and hypersensitive non-smokers!
