I found this coffee filter on Walmart.com because my wife and I were constantly waiting on our only filter to be emptied and cleaned between brews, and my first impression was that it fit our Ninja coffee maker perfectly. This one was sold by Bsnuo and was ready to use right out of the package. It saves a surprising amount of hassle because nobody has to stop and dump grounds or wash a filter before starting another cup, and that little convenience adds up fast. I like that it feels sturdy and rinses clean easily, and I notice the coffee comes through with the same rich flavor I expect from the original filter. It is a simple accessory that makes everyday coffee routines easier, and I would definitely buy another one if needed.
