High Efficient Filtration: The replaceable pre-filter acts as the first line of defense, capturing larger particles, dust, and lint before they even reach the air scrubber.

Purify the Air: Low pressure drop, superior efficiency and high dust holding capacity. It captures larger particles and helps extend the life of the high efficiency filter.

Quantity: 5pcs. Size: 15.75'' x 15.75'' x 0.75'' / 40 x 40 x 1.9 cm. The entire properly sealed filter will not leak while allowing cleaner air to flow through.
