An Air Purifier or Humidifier purifier is a device that enhances indoor air quality by filtering out toxins and allergens, including dust, pollen, pet dander, and smoke. Common filter types include HEPA, activated carbon, and UV filters, with HEPA filters capturing particles as small as 0.3 microns. Cleaned air is then released, making the environment fresher and more breathable.

Air purifiers are especially beneficial in workplaces where employees struggle with allergies or asthma, offering relief by reducing symptoms. They are also effective at eliminating odors and improving overall air quality in office settings. In locations with high dust levels or pollution, like factories and construction sites, air purifiers can significantly enhance the surrounding environment.
