Air filter media pad constructed of polyester synthetic fiber. The fiber media is durable and moisture resistant making polyester synthetic fiber media an ideal alternative to spun glass media. This offers a high arrestance and dust holding capacity making it ideal as a pre-filter for high efficiency filters.

• Prevents potential damage from stress and dampness, extending the service life of your filter
• Media with high arrestance are able to remove high quantities of dust from the air

A high dust holding capacity extends the service life of your filter by allowing it to retain high quantities of dust before replacement.
