The Makita® Fleece Filter Bag is designed for use with the Makita® 18V X2 (36V) HEPA Filter Upright Vacuum (XCV19, sold separately) to capture dust and debris. The bag features fleece for additional filtration and a double-stitched seam for added durability. Like a first-stage pre-filter, the fleece filter bag captures larger particles and extends the life of the main flat filter. It installs quickly and easily for added user convenience.
