A drop box diffuser is a type of air diffuser that is used to help improve the air quality in a room. It works by releasing small droplets of water into the air, which then evaporate and help to reduce the amount of dust, pollen, and other airborne particles in the air. This type of diffuser is often used in areas where air quality is poor, such as in homes with pets or in areas with high levels of pollution. The droplets of water released by the diffuser also help to humidify the air, which can be beneficial in dry climates. Drop box diffusers are easy to install and maintain, and they are often used in combination with other air purification systems to help improve air quality.
