Shark knows how to pitch products and you know that owning one of their vacuums keeps you hip. With bagless vacuums
, you need to regularly change the filters. If you do not, you encounter problems such as lowered suction, dirty air, or motor "choking." Keep your Shark running strong by regularly replacing the filters available through eVacuumStore.com. Filters should be changed every six to eight months.
