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.
All the components are dishwasher safe, however only the glass carafe is microwave safe. The Arctic is made from 100% Borosilicate glass which makes it both microwave and dishwasher safe. Of course, as with microwaving any food or drink, you'd need to follow the proper safety protocols; i.e. no metal, only microwave the glass carafe.
We recommend a coarse grind for the Arctic so that only the naturally delicious coffee flavors are extracted. Finer grinds may result in particles escaping into your brew. You’re always free to experiment to see what grind level works best for your brew and taste.
