Do we need an over pressure valve (blast valve) for this air filter.. In case of blast.. The PSI will increase and the contaminated air can enter in side the bunker....
How long is the usage of the filters before it has to be replaced? How do you change the contaminated filters with out it contaminating the insides of the shelter?
Hepa filters and at least 60 pounds of active carbon. On Amazon, you can get 25lbs of active carbon for $88 free ship. Hepa filters as well, cheapest place
Not sure about a plastic Air Filtration system, seems a little cheap. How many pounds of Activated Carbon?

There is no way I would use this plastic thing like this in a nukular or bomb shelter it would get eaten up by the fallout or nuke bomb ..
Can this filter out radiation and how long do these filters last?
This is a joke? That's a 12v computer fan, it's not going to pass any air through that carbon tank...
Nuke-ye-lerr🙄
There is no such thing as a nukular threat.
