ExMS,
Agree with you filters are dead duck as were Mask.
This nano particle are only effective for 7 hours which is tested fact for killing covid 19.
Any filters will last 7 hours only . It might be good for laboratory but commercially no body will buy it as was the case with mask.
But nano particle for agriculture is sounds very good . So far even this we have not Sold any on large volume.
Looking back last 3 years nothing to show for in term of sales.
They are write messages next week , next month, next year so far nothing.
