Dyson TP4A Pure Cool Tower Purifier Fan

OVERVIEW: We design our purifying fans to go beyond test chamber conditions and focus on real home conditions – this is more than just having an efficient filter.¹ Dyson engineers and research concluded that to clean an entire room properly, you need to sense pollution events automatically, capture ultrafine pollutants and project cleaner air around the room using Air Multiplier™ technology. Only the Dyson purifying fan is designed and tested to do all of this. KEY FEATURES: Senses pollutants in real time: Automatically detects and reports air quality levels in real time on PM 2.5, PM 10, VOC and NO2. Captures pollutants with 360° sealed HEPA and activated Carbon filters: The fully-sealed filter system combines an activated Carbon filter to remove gases, and a Glass HEPA filter that captures 99.97% of microscopic allergens and pollutants as small as 0.3 microns. Projects powerful airflow: Air Multiplier™ technology delivers over 77 gallons per second of smooth, yet powerful airflow – circulating purified air throughout the whole room.² Remote control: Curved to store neatly on top of the machine. Oscillates up to 350°: Adjustable oscillation angle from 45° to 350°, to help project purified air around the whole room. Backward airflow mode: Purifies without cooling you. Fan mode: Purifies while also cooling you as a fan. Quick and easy filter changing: Low maintenance, easily changeable filters. With built-in notification when they require replacing. Night-time mode: Monitors and purifies using its quiet settings, with a dimmed display.
