Efficient Air Purification The SwitchBot air purifier uses a 360° all-round air inlet design, which allows for quick and comprehensive air purification. With a CADR of up to 400 m³/h, it can cover an area of up to 166 square metres per hour. The HEPA filter effectively removes 99.97% of particles up to 0.3 microns. QUICKLY ELIMINATE PET HAIR AND ODORS The unique circulation system of the SwitchBot air purifier quickly swirls stubborn pet hair and traps it securely through large grids and special filters to prevent secondary pollution. With the special activated carbon for pets, it can effectively neutralise ammonia, hydrogen sulfide, methyl mercaptan, trimethylamine and acetic acid. THOUGHTFUL DESIGN IDEAL FOR HOUSES WITH PETS - The air purifier has chew-resistant cables and low voltage power supply, so you no longer have to worry about your pets biting the cables. In pet mode, the device intelligently adjusts the airflow speed so as not to scare your pets. In sleep mode, the noise is reduced to up to 20 dB, which allows the whole family to have a quiet night. CUSTOMIZABLE LIGHTING The SwitchBot air purifier has LED bulbs that change color automatically based on indoor air quality (blue, green, orange, red - four levels to indicate air quality). There are 10 colours and 3 brightness levels to choose from, and with the automatic shut-off and timer function, it is the perfect choice as a night light. Intelligent control: the SwitchBot air purifier supports control via an app as well as via third-party voice control (e.g. Alexa, Siri, IFTTT). The intelligent automatic mode automatically adjusts the cleaning performance based on air quality, which is energy efficient and environmentally friendly. The pre-filter is easily removable thanks to the Velcro design, making it easy to clean and maintain regularly.
