Hunter Compatible Pre-Cut Activated Charcoal Pre-Filters, 2-Pack (smaller-size version of Hunter Part #30901) can be used to replace the pre-filter in selected Hunter HEPA, HEPAtech®, QuietFlo® and PermaLife® air purifiers (models listed below). Two (2) pre-filters, each measuring 9¾" x 12⅞", can be used as is or can be "cut-to-fit" your particular air purifier, depending on the model.

Please see Owner's Manual tab for full instructions on changing the pre-filter for your model.
