Review on Enhance Performance with Artraise Rotator Lift-Away Replacement Filters by Brian Cruz

I have a Shark Rotator Professional Lift-Away (NV501) and these replacement filters work fine. As you can see from these photos, I couldn't clean the filters with just water (which is what the manufacturer recommends) and wanted a replacement when the original Shark filters dried out. I suspected the materials might not be exact replicas of the existing filters, so I weighed them on my digital scale. The replacement round disc filter can be a bit thicker and weigh 4g, while the shark filter weighs only 2g. The replacement cylindrical foam filter weighed only 12g while the original Shark filter weighed 14g. The replacement HEPA plastic filter (black) weighed only 108g. while the shark filter (grey) weighed 118 g. Also, this replacement HEPA filter looks transparent, but that may be because the color of the shark filter paper is gray while the replacement paper is white. Overall I am happy with these replacement filters and they will work very well.
