Chariho Case Study | Metalmark

Operating question

The Chariho pilot focused on whether a targeted self-renewing air cleaning system could support environmental readiness in a school setting and how that intervention should be understood alongside other operating layers.

What Metalmark did

• Evaluated Tatama® in a school pilot environment.
• Connected intervention performance to a broader view of environmental strategy.
• Documented findings in a downloadable case study PDF for stakeholder review.

What changed

The Chariho case study reports classroom particle-removal performance and modeled energy implications from using localized air cleaning alongside ventilation strategy.

Up to 5x More effective than ventilation alone for particle removal.

Up to 34% Reduction of sub-0.5 micron particles in 5 minutes.

Up to 57% Modeled classroom heating energy reduction.

Why it matters

Schools and campuses need practical, defensible decisions across complex occupied environments. The Chariho case shows how one intervention can fit into a broader readiness and verification framework.
