Since 1995 I have been using another brand's all-in-one bags, envirocare, for my company's Sebos and Windsor vacuums. Use more than 100 bags per year. These bags are about the same price as envirocare so I decided to give them a try. I think I have a commercial label on it. I had two bags that burst before they were half full and the rest leaked large amounts of dust into the vacuums. Wouldn't recommend it.
