About this Service
CBRN air filtration installation in Billings equips suburban and rural bunkers with HEPA H13 filter banks, activated carbon beds, and positive-pressure ventilation to block chemical and particulate threats. The service fits homeowners and acreage owners in the Yellowstone River valley who need clean air during wildfire smoke, industrial incidents, or biological threats. Systems are sized for bunker volume and local occupancy patterns.
Billings’ clay and silt soils affect intake placement and duct sealing. Clay layers can wick moisture into intake shafts, so installations include sealed penetrations, perimeter drains, and sump pumps where needed. HEPA H13 filters capture 99.97% of 0.3 µm particles; activated carbon beds are specified by contaminant class and expected dwell time. Overpressure blowers are selected to maintain a positive differential (typical design target 0.02–0.05 in. H2O) and are installed with redundancy and automatic transfer to standby power.
Practical expectations include verified airflow and pressure tests at handoff and a dedicated filter-change vestibule for safe swaps during a contamination event. In Billings, cold winters require insulated intake routing and attention to freeze protection for external dampers. Filter replacement is an ongoing expense; clients should budget filter stock or a maintenance agreement and plan for periodic carbon-bed exhaustion testing.
