Review on Impresserve Disposable Paper Filters: Eco-Friendly 100% Biodegradable Coffee Pods for Keurig (300 Pieces) by Will Singh

They do what they are supposed to do. Reusable K-Cups are much easier to clean. These filters are well made and well shaped. However, the coffee is noticeably WEAKER. I now use twice as much, that is 3-4 cups of K-Cup when making DeCaff Expresso coffee. Some people just run it twice on the lowest setting. I use a fresh K cup every time. Oils get absorbed by the filter so I think that's a good thing. Disposable K cups also have filters. I gave these filters a good rating because they did what they advertised.
