Определение и Значение "air purifier"

What is an "air purifier"?

An air purifier is a device used to clean the air by removing dust, allergens, smoke, and other harmful particles. It works by drawing in air, filtering out pollutants, and releasing cleaner air back into the room. Air purifiers typically use filters to trap small particles, and some models also use UV light to kill bacteria and viruses. They are commonly used in homes, offices, and places with poor air quality to improve health, reduce allergies, and create a more comfortable environment.
