Air pollution control systems are equipped with washable and reusable pre-filters designed to capture larger particles such as dust, pet hair, and coarse debris. These filters are cost-effective and help extend the life of the main filtration system by preventing clogging and reducing maintenance frequency.
However, pre-filters offer limited filtration capabilities and are not effective in removing fine contaminants, allergens, or unpleasant odors. For improved indoor air quality, especially for individuals with allergies or asthma, advanced filtration solutions like HEPA and activated carbon filters are recommended to achieve comprehensive air purification.
