The all new American made DVC Micro-Lined Nace Care NuMatic commercial canister vacuum bags are ideal for commercial cleaning companies, hotels, restaurants, schools, office buildings, and other areas which may be on a budget and not able to afford the genuine NuMatic HEPA Synthetic Cloth bags, but still want a good filtering bag. At upwards of $40 per box of bags, the genuine NuTone bags are pricey, unless you are paying in English Pounds. The DVC Microlined American made bags offer companies a much cheaper alternative, while not sacrificing on the quality. Capturing 99% of airborne allergens such as dust mites, pollen, mold and other harmful particles, with the seal rubber gasket around the bag, the only place those nasty particles are going, are in the vacuum bag, and into the trash. Fits NuMatic models Henry, Charles, Hetty, George, Basil, James, and Harry. Each package contains 5 packages of 10 bags for a total of 50 Bags. Fits NuMatic parts; 604015 NVM-1CH.
