Air pollution control systems are typically equipped with standard pre-filters designed to capture larger particles such as dust, pet hair, and large microbes. These pre-filters are washable, reusable, and require minimal maintenance, making them a cost-effective first stage in air filtration.
However, pre-filters have limited efficiency and cannot effectively trap fine particles, allergens, or odors. For environments that require cleaner and healthier air, advanced filtration solutions like HEPA or activated carbon filters are recommended to achieve superior air quality and protection.
