The Dyson Pure Cool Link Purifying Desk Fan is the perfect accompaniment for your desk either at work or at home. Ultra quiet yet incredibly powerful, this model will not only keep you cool but also improve the quality of air you breathe day in, day out. Featuring the latest in smart connectivity, with this fan you can remotely control your environment, as it automatically monitors, reacts and purifies - then reports the results straight to the Dyson Link app on your smartphone or tablet. This purifying fan is ideal for the warmer months as it automatically removes 99.95% of allergens and pollutants as small as 0.1 microns from the air, making your home environment a cleaner and more habitable one. The 360° Glass HEPA filter captures ultrafine particles from the air including pollen, bacteria and pet dander right down to 0.1 microns. On top of this a layer of activated carbon granules captures odours and potentially harmful toxins like paint fumes. The Dyson Pure Cool Fan is great all year round but comes into its own during the summer months. Not only does it provide the purification and circulation you can utilise when it's cooler, the increased airflow speed allows for great cooling when the weather heats up. The smooth oscillation projects and circulates purified air across the room, ensuring the benefits are shared by the entire room. This model also features an automatic night-time mode that monitors, reacts and purifies, but only using the quietest settings. The LED display also dims, ensuring there is no disturbance to your sleeping patterns. The Dyson Pure Cool Fan was also awarded the Quiet Mark by the Noise Abatement Society and certified asthma & allergy friendly™ by Allergy Standards Limited.
