In my quest to cut down on K-cup waste, I've been in search of a coffee filter system that didn't take too much counter space and would actually produce WARM coffee. After one false start, OXO comes to the rescue with their pour over coffee filter. Just the right size, the covered water filter insures not just a warm cup of coffee, but downright HOT! I'm enjoying grinding my own beans again and savoring a cup of coffee that is filtered to true taste. While the #2 filters do produce SOME waste, overall, the impact is much less than plastic k-cups. I'm enjoying this product on a daily basis.
