When I first installed this product I thought it would be tighter than the original but I thought nothing of it as my vacuum seemed to work. My original filter worked fine, but I wanted the secondary filter to turn off while the other dries after cleaning. Well, I kept noticing that this new filter doesn't pick up dust - it instead seems to collect in the cup around the filter and after a few uses the suction wasn't as good - switched to the old original and the suction was the back. . Too late to return but I started paying more again and ordered the original Shark as a replacement. It's better to overpay for replacement parts than to ruin the vacuum cleaner.
