Help ?
Presuming you're talking about 3M's exhalation valve filter, it does have only "99% Bacterial Filtration Efficiency (BFE) based on testing conducted per ASTM F2101" and is NIOSH approved (which even at $9 a piece isn't too shabby). You have an even better performing solution you'd like to share Obie? Or perhaps you want to walk back that "The respirator MyManao has chosen would work better if he strapped it to his butt / a cartridge that is rated to stop covid ... doesn't exist so you respirator is useless for use over you mouth and nose" silliness in the interest of not contributing to more mask misinformation?

Thanks! Not planning on sticking around given the ongoing nonsense & mis/dis-information that has become so common here, but wish you both well in continuing to keep up the good fight against it - I'm sure the boulder will make it to the top next time!
