The Dyson PH05 Purifier Humidify+Cool PH2 De-NOx is a versatile floor-standing device that combines air purification, humidification, and cooling in one unit. It features a comprehensive filtration system including a HEPA H13 filter to capture 99.95% of particles, a catalytic filter for formaldehyde removal, and a K-Carbon filter impregnated with potassium carbonate to adsorb nitrogen dioxide. This makes it a practical choice for maintaining air quality in rooms up to 81 cubic meters for purification and 41 cubic meters for humidification. Designed in a white and gold finish, the plastic housing stands 92.3 cm tall with a square base of 31.2 cm. It includes a 5-liter water tank that supports up to 36 hours of operation, while the cooling fan can oscillate at 45°, 90°, or in a full rotation to distribute air evenly. Weighing 8.12 kg and consuming 45 W of power, the unit is managed via an electronic LCD display, an included remote, or the MyDyson app, with added convenience from Amazon Alexa, Siri, and Google Assistant integration. This system suits those who want to manage multiple aspects of their indoor environment through a single interface. The 1.8-meter power cable allows for flexible placement, and the on/off timer helps you schedule the device to fit your daily routine, while the maximum noise level of 62 dB ensures it remains manageable during use.
