How a Law Enforcement Shooting Range Improved IAQ—While Lowering Costs

When a high-traffic shooting range began to experience a sharp spike in usage, it triggered a cascade of air quality issues. What was once a controlled, safe indoor environment quickly became a costly and hazardous challenge for the facility’s maintenance team.

Puremaxx was called in to help—and what followed was a dramatic transformation in both performance and cost savings.

The Challenge: Poor Air Quality & Soaring Costs

With the range seeing significantly more foot traffic, the indoor air quality (IAQ) dropped quickly. Here’s what was happening behind the scenes:

• The air in the range became unsafe due to lead particles and dust

• Pre-filters needed to be changed weekly, requiring full hazmat-style suit-up

• Labor hours doubled

• Air conditioning units were under constant strain

• Energy costs climbed due to restricted airflow and overworked systems

Our Approach: Strategic Filter Upgrades

We began our audit by assessing each stage of the filtration system and recommending smarter, higher-performance replacements.

Step 1: Upgrade Pre-Filters

The existing filters couldn’t keep up with the contaminant load. We replaced them with high-capacity pleated filters, instantly extending changeouts from weekly to bi-weekly—cutting labor in half and improving airflow almost immediately.

Step 2: Optimize Secondary Filters

The facility was using 8-pocket, 12” deep bag filters. After measuring available space in the units, we recommended a shift to 10-pocket, 18” deep bags. This adjustment doubled filter life and moved the changeout schedule from monthly to bi-monthly.

Step 3: Assess Final Stage – HEPA Filters

Although the HEPA filters didn’t require replacement at the time, we reviewed options to further reduce static pressure, increase filter life, and lower overall cost—giving the team future-ready insights to stay ahead of maintenance needs.

The Results: Measurable Efficiency & Safer Air

Following the audit and filter upgrade implementation, the facility saw:

• 50% Reduction in Labor: Fewer changeouts = less time in full PPE

• Double the A/C Uptime: Units ran more efficiently and stayed online

• Improved Airflow: Cleaner air and better user experience for trainees

• 10% Annual Filter Cost Savings: Better pricing on long-life HEPA filters

• Reduced Energy Costs: Lower pressure drop = more efficient airflow

• 50% Cut in Disposal Volume: Thanks to extended filter life

Why It Matters

As filtration technology evolves, so does the opportunity to optimize HVAC performance and cost—especially in high-demand, high-risk environments like shooting ranges.

Whether you’re managing a law enforcement facility, an industrial space, or a cleanroom, strategic filter upgrades and on-site audits can unlock massive efficiency gains without sacrificing safety or air quality.
