All of the components can be separated for easy cleaning and are dishwasher safe, but you can also clean the Glass Carafe and Micron Filter with a soft bristled cleaning brush for bottles. You'll get the best results if you wash the Arctic immediately after use.
Specifically for the Micron Filter, once you've deemed your brew time complete (12-24 hrs is suggested but you're always free to experiment with what works for you), the filter should be removed and cleaned immediately for the best results every brew.
