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. 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).
