QUESTIONS & ANSWERS
Do the mask and NBC-77 SOF filters that you can buy in the bundle both have a 20-year shelf life?
Yes, they do.
If you use it for Coronavirus, which model do you suggest? Do you need to change the filter each time if you go out with possible affected patients around?
This mask, as long as it’s used per best practices and forms a tight seal, would protect your breathing passages and eyes from viral threats. A filter cannot be regenerated in any way, and once used, it is considered toxic waste and must be disposed of. So to answer your question, yes, you would have to change the filter each time if it’s exposed to a viral agent.
How long will a NBC-77 SOF filter protect in non-contaminated air against viruses?
As viruses travel in particles and liquid aerosols, this filter will protect you for as long as you can wear the mask (several days). Keep in mind; if you are in a contaminated environment, you would need to decontaminate properly before removing your protective gear, and then dispose of the filter as there is no way to regenerate it. Once the filter is used in a contaminated environment, it is considered toxic waste.
What is the benefit of using two filters at the same time?
Two filters would lower the breathing resistance, at the expense of added weight. We suggest using one filter at a time for most purposes.
