I'm excited about the new filter. I should have bought this sooner because I've really been battling allergies and I feel like these new filters have breathed new life into my vacuum! Immediately noticed a difference in suction power. I washed my other filters regularly before I bought them, but you can only do that for so long with the material they're made of. Will definitely buy again if they need replacing. Thanks for a great product at a reasonable price!
