Dzanda.... The lead police! Truly, it is a dangerous substance and I am aware you know all about it medically.
I, for one, appreciate your concerns.
So, get a look on like Harrywally's avatar, don some disposable gloves, work over plastic sheeting, toss the filters from the respirator and the gloves onto the sheet. Tie it up into a plastic bag. Give it to Dexter. He will dispose of it! Then, a 45 minute shower. Wait! The lead is now everywhere! What do you guys know about lead? I think it is made by smelting. IS there a substitute which is being used in fishing weights? I feel that there is not a substitute for bullets or shot which would be remotely cost-effective . Steel shot sure sucks!
Finally, my daughter is going on a Mission trip to Leadville Colorado this summer. Wonder what used to be THERE?
