Top twist of, and there is a filter inside.

[melgd]

[bobdylan]

Replace.

Thanks, Bob
You say the top screws off. Must have fine internal threads? this lid is only about 1/8" tall. Been soaking all night in solvent. I have learned to be patient. Should not have to use 2 pair of channel locks, don't want to screw it up
