These are the only bags I buy for my Hoover vacuum. They work great if you are allergic to dust. It was a good price for the quantity I bought. I only use the original Hoover vacuums that came with my vacuum. These are genuine Hoover allergy bags. I will continue to buy them. I gave 4 stars for easy installation because sometimes I have to pierce the cardboard as it isn't always fully perforated so I have to struggle to put them on the plastic tube and it takes two to three tries to get it stays right on the pipe. . Thankfully, that can only happen with one or two bags.
