Air purification is the process of removing contaminants from the air to improve its quality. This can involve filtering out dust, pollen, smoke, and other pollutants using various methods, such as mechanical filters, chemical absorption, or ultraviolet light. Air purifiers are commonly used in homes, offices, and hospitals to create a healthier environment. The benefits of air purification include reducing allergens, improving respiratory health, and eliminating unpleasant odors. Many air purifiers are designed to capture particles as small as 0.3 microns, making them effective against a wide range of airborne pollutants. Regular maintenance of these devices is essential for optimal performance.
