Did you know that your vacuum, has filters that should be checked frequently. Depending on your household, your friends at Bissell recommend replacing your vacuum filters every 3 to 6 months or when performance begins to decline and more often if you have pets that shed and family/friends that track in dirt and debris. Refer to your Bissell vacuum owner manual for replacement instructions. It is a good idea to buy an extra filter to always have one ready to use.
