K&J 12-Pack KEURIG Compatible Water Filters - Universal Fit (NOT CUISINART) Keurig Compatible Filters - Replacement Charcoal Water Filters for Keurig 2.0 (and older) Coffee Machines

I bought these for use with my Keurig K-40 Coffee Maker. They work great, and are a great value. Highly recommended.After cleaning my Keurig recently and inserting a new water filter, I was chagrined to discover that the coffee maker wasn't working properly -- it didn't seem to be priming properly and would whir and whir endlessly, with no output.After a bit of troubleshooting, I realized that air was trapped in the water filter assembly, and was apparently causing the pump not to prime properly. So here's a tip: Follow the directions for preparing a new water filter (soak at least five minutes in tap water and rinse to remove any loose charcoal particles). Then when inserting into the water reservoir, gently "tilt" the filter assembly to near-horizontal. This will allow any air trapped in the filter assembly to escape (evidenced by bubbles). Finally, re-affix the filter to the intake on the bottom of the water reservoir and you should be good to go.

I guess you pay for what you get. One of the pods I've used so far contained a ferrous metal which rusted in the Keurig and caused damange to the machine.

At first I was hesitant to buy these filters after reading some reviews about the water being gray. But I decided to bite the bullet and just try them. The directions say to soak the filter in water for 15 minutes. I gave it a few minutes longer, at 20 minutes just because. And that was the only time the water was a little gray, but that was obviously because the charcoal filter was just soaking in the bowl. But after testing it, the water going through the Keurig was totally fine.I think for those who had gray water it was probably because they either didn’t soak it long enough, or maybe they need to clean out their Keurig too every once in a while. I know everyone’s experience differs, but I just wanted to share my positive experience with those who may be hesitant like I was!Plus, a 12-pack for a great deal. These will last me 2 years before I have to order another pack (change out every 2 months obvs). Awesome!

We have had our Keurig for almost two years with no filter issues. After one use of this pack it left the pieces stained with what looks like rust or mold. After much scrubbing soaking and washing the stains remain on these pieces and inside the reservoir.
