WAVEDUST Replacement Duster Heads are made of durable microfiber. Microfibers trap more dirt than regular cotton fibers, making them a much more efficient cleaning material. The debris channel design locks dirt in place, so you don't have to make multiple passes and don't need dust mop treatment -- a great money-saving feature.
These duster heads are designed to withstand up to 750 launderings, giving you exceptionally long life.
Note: Do not use fabric softeners when washing microfibers, as it can interfere with its dust-collecting ability.
