HEPA-Grade CBRN Air Filtration Installation in Livingston, Montana

Common Challenges

• Contaminated air seeps through cracks without positive pressure

  Bunkers without overpressure blowers let chemical vapors and airborne particles infiltrate through ventilation gaps, door seals, and foundation cracks during events.

• Single-stage filters miss chemical vapors or fine particles

  HEPA-only systems capture particles but not chemical agents. Carbon-only filters miss biological particles. Both stages are required for NBC protection.

• Cold Montana winters freeze blower motors without insulation

  Livingston's cold winters with significant snow cause uninsulated blower motors to seize, leaving your bunker without air circulation when you need it most.

How We Help

• HEPA H13 filters capture 99.97% of particles down to 0.3 microns

  Filter banks remove biological agents, radioactive dust, and fine particulates that single-stage systems miss, meeting NBC protection standards.

• Activated carbon banks remove chemical vapors and gases

  Carbon filtration absorbs nerve agents, industrial chemicals, and toxic gases that HEPA filters alone cannot block.

• Overpressure blowers maintain positive pressure inside the bunker

  Continuous positive pressure prevents contaminated air from entering through cracks, vents, or door seals during chemical or radiological events.

• Filter change protocols let you swap filters safely during events

  Documented procedures for replacing saturated filters without exposing occupants to contaminated air, extending your shelter time.

• Insulated blower housings prevent freeze-up in Livingston winters

  Cold-weather insulation keeps blower motors operational during Montana's cold winters with significant snow, ensuring air circulation year-round.
