ARM & HAMMER Vacuum Bags
ARM & HAMMER premium vacuum bags and filters are recommend by four out of five allergists because they rid the home of allergy triggers by retaining up to 100 percent of dust mite debris, household fibers, grass and ragweed pollens, plus particles 15 times smaller than the diameter of a human hair.
