Sometimes you just need to change the "oops filter" that's what I call it anyway. when Someone messes with the bag and doesn't get it back like it should be, then we have an "Oops" no worries is you have an extra filter on hand
The product description states "2 Replacement Vacuum FIlters Included." When the package arrives, it contains only 1 filter. $9.99 for one piece of foam!
After waiting 20 days, my order was cancelled because it wasn't in stock. However, it was in stock when I purchased it. Waiting for my credit. As far as the product goes, it's necessary to use this with the canister vac so that the dust doesn't get caught in the motor.
