Review on Party Bargains 300 Disposable K-Cup Paper Coffee Filters - White, Ideal Coffee Filters for Keurig Single Serve Brewers, Optimum Size and Ample Quantity by Jeffrey Johnston

I was pleased with these filters, but they did not live up to my expectations. First, I have several different brands of reusable K-Cups. Some of the K cups didn't close when I used these filters. The purpose of the filters for me was that I could fill the K-Cup and then after use I could just remove the filter and put in a clean filter without having to shake out the used grist and then rinse out the K-Cup. When I was finally able to pull the filter out, there was still a small amount of coffee at the bottom of the K cup, so I had to rinse it out anyway. Another issue was that some of the soil got into my coffee cup due to the filter not allowing the K-cup lid to close properly. All in all a waste of money.
