The Nu-Calgon 6106-10 ClenAir HVAC Odor Block Commercial is engineered to eliminate persistent odors in large commercial HVAC systems. Previously sold under part number 61061, this commercial formulation is designed for 10 to 15 ton systems and delivers continuous odor control for up to 4 months.

Unlike masking agents or fragrance-based products, ClenAir molecularly reacts with airborne odor-causing compounds and neutralizes them. As air circulates through the HVAC system, the self-feeding package slowly evaporates into the return air stream, treating all conditioned air throughout the building.

Ideal for commercial facilities experiencing odors from mold, mildew, smoke, water damage, chemicals, garbage areas, sewer gases, or stale air.
