Keurig Reusable Ground Coffee Filter Compatible Essentials and K-Duo Brewers only, Eco-Friendly Way to Brew a Carafe, Gold Tone Mesh

it is only to be used for keurig i have found it to be that specific no retrofit on this gold tone filter

Nice to not have to worry about running out of filters.

This is simple to use and clean. Just what I wanted.

Saves me from having to buy disposable filters. Works great, easy to clean. Fits perfect. No funny aftertaste in my coffee so it doesnt leach as far as I can tell.

We were using paper filters in our keurig duo and the grounds would always overflow over the paper and make a big mess. This filter fit perfectly and the water is able to drain quick enough that it doesn’t overflow and make a mess. Coffee still takes great too :)

Permanent filter, no waste, easy clean up and you don’t have to constantly buy paper filters.

Fits my machine. Coffee tastes better than with paper filters. No coffee grounds in my cup.

We purchased the K-duo at Walmart but it didnt come with a brew filter, so I found this online. Luckily it wasnt very expensive but it should be included at in-store K-duo boxes. The brew flavor is fairly poor compared to brew-exclusive units in my experience.

Exactly what I needed. Fast delivery. I’m very satisfied.

Bought the wife a K-duo Keurig brewer for the holidays and wanted to get every little accessory to go with it. This did not fit in our brewer at all despite our model being mentioned in the description. Bought it too early and found out far too late for a refund cest la vie.
