Review on Advanced CapReplace - Powering ConPus Navigator with Professional Capabilities by Paul Wilson

Performance drop in vacuum. After replacing them on my Shark, I'm happy to report that its tremendous suction power has been fully restored and it's working just as well as it did on day one. So performance wise these filters are big winners in my opinion as they fit perfectly and recover like my 3 year old shark's new specs. The great thing about these filters is that despite the low price, there was hardly any difference in quality. ConPus filters and OEM Shark filters. I placed them side by side and couldn't tell any qualitative difference between them (apart from the fact that my OEM filters were golden brown to match the color of my vacuum). So if you are looking for replacement filters for your Shark I highly recommend these filters. 5 Stars
