Frequently Asked Questions

Common questions about CBRN air filtration in Kalispell bunkers

Answers about NBC filtration systems, filter maintenance, and overpressure requirements for Flathead Valley properties.

Without positive pressure, contaminated air seeps in through cracks and ventilation gaps even with HEPA filters installed. Nerve agents and radioactive particles infiltrate the bunker, exposing your family during the event. Overpressure blowers create positive pressure that blocks infiltration, keeping contaminated air outside where HEPA and carbon filters can capture it.

Bunkers without NBC filtration offer no protection during chemical, biological, or radiological events. Your family breathes contaminated air, leading to chemical exposure, radiation sickness, or pathogen infection. Installing filtration after an event starts is impossible. Early installation ensures your bunker works when threats escalate, saving lives during the crisis.

HEPA H13 filters last 3-5 years under normal use, carbon filters 2-3 years depending on humidity. During CBRN events, filters may need replacement after days or weeks of heavy contamination. We provide filter change protocols and pre-filters to extend main filter life. Stock spare filters on-site for extended events.

Yes. We retrofit NBC filtration into existing bunkers by mounting HEPA and carbon filter banks, integrating overpressure blowers, and sealing ductwork. Retrofits require space for filter banks and blower units. We assess your bunker layout, calculate airflow needs, and design a system that fits your shelter's footprint and occupant load.

Blower size depends on bunker volume, occupant count, and desired air changes per hour. A 500 cubic foot bunker with 4 occupants typically needs a blower delivering 100-150 CFM to maintain positive pressure. We calculate your specific requirements during system design, ensuring the blower can overcome filter resistance and maintain pressure during filter loading.

NBC filtration requires continuous power for overpressure blowers. We integrate filtration with your bunker's off-grid power system (solar, generator, or battery bank) to ensure operation during grid failures. Blowers draw 200-500 watts depending on size. Backup power is mandatory for CBRN protection during extended events when the grid is down.

Filter change protocols include sealing the bunker, shutting down the blower, donning protective gear, removing contaminated filters into sealed bags, installing fresh filters, and restarting the system. We train you on these procedures during handoff. Pre-filters reduce main filter contamination, extending time between changes. Stock spare filters and PPE on-site before events.
