Most air pollution control equipment is equipped with durable pre-filters designed to trap larger particles such as dust, pet hair, and sizable microbes. These washable and reusable pre-filters help extend the life of the main filtration system, making them cost-effective and low-maintenance.
However, pre-filters only capture large contaminants and are not effective at removing smaller airborne particles, allergens, or unpleasant odors. For comprehensive air purification, they are typically paired with advanced filters like HEPA or activated carbon filters, ensuring cleaner and healthier indoor air.
