The Di Oro MaxBrew includes a 24K gold-plated honeycomb-patterned filter that stands the test of time since it won’t absorb unpleasant flavors. It’s compatible with Keurig 2.0 and 1.0 brewers, including the K200, K250, K300, K350, K360, K400, K450, K460, K500, K550, K560, and many others.
MaxBrew Reusable K-Cup Filter is 100% BPA, Lead, and DEHP Free and can be easily cleaned by hand or in a dishwasher, top-rack only.
Rated very highly on Amazon, the Di Oro MaxBrew nonetheless is noted by some as requiring some trial-and-error. It seems some types of coffee grounds will leak out, although not most.
