No, I began my response with the TRUTH. Masks do NOT filter out viruses. The typical paper mask that you see people wearing around are rated for particles of size 3+ microns. COVID is approximately 0.1 microns in diameter. IOW, COVID will go right through the mask pores.So you begin your response with a lie,
Why do you pretend not to know this?
Are engineering specs and basic mathematics hard to understand?and expect others to believe you. Typical.
Try doing your own thinking for a change...
