These bags do a great job at holding in the super fine dust particles that make me stuffy and sneezy. I used to use a different brand of generic bags that would spray dust all over the place when trying to change them out and with these new bags I don't have that problem. They are very easy to install and remove, and they hold a lot more than I thought they would. Because they hold so much I find myself not having to change the bag nearly as often. A++
