How long does ARM & HAMMER® Baking Soda work in vacuum bags and filters?
Bags and filters are packaged to preserve maximum deodorizing potential so you get full strength protection when you first install the bag or filter in your vacuum. The deodorizing ingredient is effective until your bag or filter is replaced, providing you replace your bags as recommended every one to two months and filters every 90-120 days. For more information on changing your bags and filters, refer to our Usage Tips section.
