When a high-volume truck manufacturer began experiencing filter pull-through on their rooftop HVAC units after just one week, it signaled a serious issue. The combination of grinding operations and nearby paint mist was pushing their filtration system to the limit. With no roof hatch and filters needing to be hauled up the side of the building, the process was not only labor-intensive—it was unsustainable.

The Challenges

• Filters were pulling through in one week, exposing HVAC coils to dirt and contaminants
• Labor was extensive due to difficult rooftop access and frequent changes
• Filter costs were high due to the volume and frequency of replacement
• Dirty coils increased HVAC maintenance and reduced performance

The Solution

Puremaxx conducted an on-site filtration analysis and implemented a strategic upgrade to high-velocity, high-capacity filters. The result? A significant performance boost without the need for major HVAC modifications.

Key Outcomes

• Filter lifespan doubled: From one week to two weeks without pull-through
• Labor cut by 50%: Half the filter changeouts reduced strain on facility staff
• Cost-neutral solution: Filters were twice the cost, but usage was halved
• Administrative time reduced: Fewer orders and simplified management
• Higher filtration efficiency: Upgraded from MERV 8 to MERV 10
• Improved coil health: Better filtration meant cleaner coils and fewer maintenance calls

While energy savings were not formally tracked, the improved airflow and reduced coil fouling strongly suggest additional gains in system efficiency.

Automation That Saves Time

To lock in the labor and admin savings, Puremaxx also enrolled the customer in bi-weekly automated deliveries. This ensured the right filters arrived exactly when needed, with no manual ordering required.

The Bottom Line

With a smarter filtration strategy, this manufacturer achieved measurable improvements in labor, maintenance, and indoor air quality—without increasing overall filter spend. It’s another example of how Puremaxx helps industrial clients work smarter, not harder.
