Review on Anewise WindTunnel Bagless 303173001 303172001 by Heather Taylor

Reading the reviews of this brand's filters listed on Amazon individually and not in this set I realized they work reasonably well but don't quite fit. They didn't look like Rockstar spare parts. But people also appreciated some weird things, like the HEPA exhaust filter on the bottom, which didn't look exactly like the one that said "HEPA." Another complained that the bottom filter popped out when he turned on the vacuum. Another said that the primary filter (blue inside) is not as thick as the original filter and feels cheap. I have no complaints. These replacement filters will fit and work. The primary filter is just as thick and malleable as the original. Ideal for vacuum. The exhaust HEPA filter has a slightly different design, but without any negative consequences. The bottom protrusions that attach it to the vacuum cleaner are exactly the same. The side tabs that attach it to the vacuum are set back a little further (see photo in my review). Instead of snapping into place like the original, it just presses firmly into place. That's the only difference I found. And it's black, not dark grey. Although I don't mind.
