It is used in combination with HEPA filters to prevent premature replacement of HEPA filters due to dust accumulation, thus extending the service life of HEPA filters.

High-quality filter media, reasonable design, high dust holding capacity and low resistance.

The high-quality fluffy filter media is used. The filter media is a special mixture of non-woven fabric and synthetic fiber, with a special contour pleat design to provide a larger dust holding capacity and increase the utilization of the filter media. A reasonable number of filter pulp pleats increases the effective use area of the filter and reduces the resistance at the same time.
