Frequently Asked Questions

Common questions about CBRN air filtration systems

Answers about HEPA filters, overpressure blowers, filter changes, and system maintenance for Montana bunkers.

Contaminated air infiltrates through cracks, door seals, and ventilation without filtration and positive pressure. Chemical vapors, biological agents, and radioactive particles enter the shelter, exposing occupants to the same threats they're trying to avoid. Installing HEPA H13 and carbon filtration with overpressure blowers blocks infiltration and maintains breathable air for months.

DIY filters lack HEPA H13 certification and carbon weight to remove sub-micron particles and chemical vapors. Without overpressure blowers, contaminated air seeps in through gaps. Filter failure during an event means exposure to nerve agents, pathogens, or radioactive dust with no backup. Professional NBC systems with tested filter banks and positive pressure prevent infiltration when it matters most.

Pre-filters need replacement every 3-6 months depending on dust levels. HEPA H13 filters last 1-2 years in standby mode or weeks during heavy contamination events. Activated carbon filters saturate after 6-12 months or sooner with chemical exposure. We provide filter change protocols and bag-out procedures for safe replacement without compromising shelter integrity.

Overpressure means maintaining higher air pressure inside the bunker than outside, typically 0.1-0.3 inches water column. This positive pressure prevents contaminated air from seeping in through cracks, door seals, or ventilation gaps. Without overpressure, filtration alone cannot stop infiltration. Variable-speed blowers maintain pressure while circulating filtered air throughout the shelter.

Yes, with proper protocols. We install isolation valves upstream and downstream of filter banks, plus bag-out ports that let you remove saturated filters into sealed bags without exposing shelter air to contaminants. Pre-filtration stages reduce HEPA clogging, extending time between changes. We provide step-by-step procedures for safe filter replacement during events.

Yes. HEPA H13 filters remove smoke particulates, ash, and PM2.5 pollution. Activated carbon filters adsorb volatile organic compounds and odors from fires. Overpressure prevents smoke infiltration through cracks. While designed for chemical, biological, and radiological threats, NBC filtration systems also protect against wildfire smoke and poor air quality events common in Montana.

We test every installation with manometers to verify overpressure levels and airflow meters to confirm CFM rates match design specs. Filter banks are inspected for proper sealing and bypass leaks. You receive documentation of pressure readings, airflow rates, and filter specifications. We also provide maintenance checklists and filter change schedules so you can verify system readiness before events.
