An upgraded Chaff Filter for older Bullet R1 models (pre-April 2017).
Chaff Filter w/ Adapter
This Chaff Filter is an improvement on the model that came standard with roasters prior to April of 2017. It rarely needs to be cleaned, but is also easily removed when a cleaning becomes necessary. And because the filter does not clog, the airflow within the roaster is more consistent from roast to roast. Highly-recommended upgrade.
