With thousands of deep-cleaning fibers, Swiffer® 360? dusters reduce up to 90% of inanimate allergens from cat and dog dander and dust mite matter. Designed specifically to clean dirt in grooves and crevices, it traps and locks dust and allergens better than a feather duster. Its smart all-around design has 50% more fibers than regular Swiffer® dusters. Short, flexible plastic handle for added reach. Includes one duster per kit. 12 kits per case.
