S10 respirator protection

We're waiting for Ash Ling to read recent responses and update the status.

Dear Defence Science and Technology Laboratory,
I am writing to make a request for all the information to which I am entitled under Freedom of Information Act 2000 regarding the S10 respirator and its filters.
1) What is its level of protection according to industrial standards - what percent of particles can it block?
2) How long can a singular filter last before needing replacing in a environment exposed to a nerve agent such as sarin or VX gas?
3) Has the respirator and its filter been proved proof against anthrax spores?
4) Has the respirator and its filter been proved proof against any viruses in the size between 50-200 nanometres of diameter?
Yours faithfully,
Ash Ling
