The "Multi-Guard" pocket filter is made with a dual layer, electrostatically-enhanced synthetic fiber media that provides high efficiency with low resistance and outstanding dust containment capacity. The filter is especially effective with small particles of less than one micron. A gradient density fiber structure captures particles throughout the entire depth of the media. The filters are not affected by humidity and resistant to chemicals or microbial growth.
