Purification systems are technologies designed to remove contaminants from air, water, or other substances. These systems can include methods such as filtration, distillation, and chemical treatment. They are commonly used in households, industries, and laboratories to ensure that the environment and products are safe for use. In water purification, for example, systems may utilize reverse osmosis or UV light to eliminate harmful bacteria and pollutants. Similarly, air purification systems often employ HEPA filters to trap dust, allergens, and other airborne particles, improving indoor air quality and promoting better health.
