This kit is a good addition to your brewer as it has a bottle of descale solution and 2 water filters, and 2 rinse pods for removing scale in the water tank and keeping the water fresh and clean. This kit wil last for 3 months between cleanings. I use it every time the brewer needs to be cleaned.The rinse pods help keep the needles clean and free of grounds, which is great. I recommend this kit to help maintain a brewer and insure a trouble free brewing cycle.
