Good quality does not always have to be expensive. The vacuum cleaner bags from Swirl scored the best in the Stiftung Warentest test - the German consumer organization who put 22 branded vacuum cleaner bags to the test and evaluated their performance. Third-party bags are in most cases just as powerful as the originals but sometimes cost only about half. Thirty-three bags from third-party suppliers, such as Swirl, were compared with three original bags in terms of handling, dust absorption, and retention, as well as fit and durability. The Swirl vacuum cleaner bags' results were particularly convincing. More specifically, the tests showed that the vacuum cleaners using Swirl bags performed even better when filtering the dust than the original bags.
