122781 HEPA 2000 MERV 11 prefilter, case of 12

Dri-Eaz 122781 is the case of 12 replacement 24 x 24 x 2-inch MERV 11 prefilters designed specifically for HEPA 2000 equipment 123668. Legend Brands currently calls the media paper on the product page and heavy-duty synthetic fiber in manual 123679B, so no single material composition is asserted. The disposable prefilter extends primary-filter life and must not be cleaned or reused. Confirm model 123668, case quantity, dimensions, installed filter position, contamination conditions, and current manufacturer instructions before ordering.
