 Air filtration in gun ranges is crucial for safeguarding workers and visitors from inhaling harmful airborne particles produced by gunfire, such as lead, copper, and other heavy metals. The following are key air filtration requirements for gun ranges:

1. HEPA Filters: HEPA filters are essential for capturing fine particulate matter generated by gunfire. These filters must have a minimum efficiency of 99.97% in removing particles as small as 0.3 microns.
2. Ventilation Rates: Gun ranges require higher ventilation rates compared to commercial or residential buildings. The National Institute for Occupational Safety and Health (NIOSH) recommends a minimum of six air changes per hour (ACH) for gun ranges.
3. Air Pressure Control: Effective air pressure control is necessary to prevent the spread of airborne particles to other areas. Negative air pressure helps contain the air within the shooting range, while positive air pressure in adjacent areas helps keep contaminated air from spreading.
4. Regular Maintenance and Monitoring: Routine maintenance and monitoring are vital to ensure air filtration systems are working properly and maintaining air quality. This includes regular filter changes, cleaning of air ducts and ventilation systems, and ongoing air quality assessments.

Compliance with regulatory standards from organizations such as OSHA and the Environmental Protection Agency (EPA) is also required.
