They are definitely worth it. Not as pretty as OEM, but not essential for performance. I immediately went to the test, I had to vacuum diatomaceous earth (a very fine powdery fossil) as I ran out of vacuum cleaner bags at the store. When I checked the tank, everything was fine. No loss of suction. Nothing hides the inside. The fake #90671 vacuum cleaner bags I received couldn't even do that. I was also happy with my purchase of the Aqua Green humidifier filters so I was confident they would work. I first tried a cheaper brand of similar vacuum bags but there was no comparison and this was only tried with regular junk. Very impressed, would definitely recommend as equal/same OEM performance at an affordable price.
