Frequently Asked Questions

Common questions about CBRN air filtration for Missoula bunkers

Answers about filter types, overpressure systems, and maintenance for NBC-rated air purification

Without NBC filtration, your bunker offers no protection from airborne threats. Chemical spills, wildfire smoke, or radiological events will infiltrate through ventilation and cracks. A family sheltering without HEPA and carbon filters faces exposure to the same contaminants they tried to escape. Installing filtration after an event starts means breathing contaminated air during setup.

Standard HVAC filters lack HEPA H13 and activated carbon layers needed to remove chemical vapors and radioactive particles. DIY systems cannot maintain positive pressure, letting contaminated air seep through cracks. Filter efficiency below 99.97% means nerve agents and pathogens enter your bunker. Without overpressure blowers, you have ventilation but no protection.

CBRN filtration systems do not typically require separate permits in Missoula, but electrical work for overpressure blowers must meet Montana electrical code. If your bunker is part of new construction or basement conversion, the air system is included in your building permit. We handle all code compliance and electrical inspections.

HEPA H13 filters capture 99.97% of particles down to 0.3 microns including radioactive dust, biological agents, and smoke. Activated carbon filters adsorb chemical vapors and gases like nerve agents and industrial chemicals. Multi-stage filtration removes both particulate and gaseous threats before air enters your bunker.

HEPA and carbon filters last 6-12 months under normal standby conditions. During an actual contamination event, filters may need replacement after days or weeks depending on contaminant concentration. We provide filter change protocols so you can swap filters safely without exposure. Pre-filters extend main filter life by capturing larger particles first.

Yes. HEPA H13 filters remove smoke particulates and ash, while activated carbon filters adsorb volatile organic compounds from burning materials. Overpressure blowers prevent smoke infiltration through cracks. Montana wildfire seasons produce heavy smoke that standard ventilation cannot block. NBC filtration keeps bunker air breathable during extended smoke events.

We size overpressure blowers to maintain 0.5 to 1.0 inches of water column positive pressure inside your bunker. This pressure differential prevents contaminated outside air from infiltrating through cracks or ventilation gaps. Pressure testing before handoff verifies your system meets NBC protection standards for your bunker volume and occupancy.
