Ensure your model matches for optimal performance before making a purchase. - Quality Construction : Made with high-density pre-filter materials, the BKJ-33 filter offers anti-folding properties and resistance to oil, acid, and alkali. This effectively traps large particles of pollutants, ensuring cleaner air in your environment. - Enhanced Airflow : Featuring H13 HEPA technology with evenly spaced pleats, this filter minimizes wind resistance and promotes rapid air circulation, allowing for efficient purifying of indoor air. - Odor Elimination : The filter is equipped with high-efficiency activated carbon that is evenly distributed, maximizing the contact area for enhanced gas absorption.
