An apuifier, or air purifier, is a device designed to remove contaminants from the air in a room or enclosed space. It typically uses filters, such as HEPA filters, to capture dust, allergens, smoke, and other pollutants, improving indoor air quality. Some models also incorporate technologies like UV light or ionizers to further purify the air. Air purifiers are often used to alleviate Allergies, Asthma symptoms, and other respiratory issues.
