No, the Atmos is not dishwasher safe.
When it comes to the lid, please prevent liquid from getting inside and do not clean the lid under running water. Instead, clean with a damp, non-abrasive sponge and use mild soap, if needed. For thorough cleaning, the gasket and filter can be removed and washed separately.
Similarly, we recommend hand-washing the stainless steel and glass canister with a damp, non-abrasive sponge and mild soap. Using a coarse sponge, brush or other rough surfaces will scratch the finish of the lid and canister. If any sign of corrosion is discovered in the stainless steel canister, use a soft sponge to apply a polishing compound and rinse thoroughly afterward.
