How do I remove the pollen screen?Updated a year ago

Next Gen Premiums come with a removeable pollen screen. To remove the stainless screen:

1. Unthread the lower catch. 
2. Unthread the ring holding the pollen screen
3. Remove the thin black plastic retainer at the bottom of the pollen screen. The stainless disc will come out and stay with the plastic retainer.
4. Thread the ring section back onto the catch.
