Smoke and Marijuana Odor Removal in Multifamily Buildings

Cannabis and tobacco smoke are made of particulates that bind to drywall, carpet padding, and HVAC filters. Once they bind, conventional ventilation does not remove them — it spreads them.

Why ozone and "air scrubbers" are partial answers Ozone damages plastics and rubber gaskets, and can't run while units are occupied. Portable scrubbers help one room while the smoke continues migrating from the source.

Smoke Odor Shield in the HVAC return For hotels and multifamily, our Smoke Odor Shield is installed discreetly inside the HVAC return duct of the affected unit or room. It runs continuously, breaking down smoke and marijuana odor molecules at the point where the air is being recirculated — not masking them with fragrance. Rooms come back online guest-ready instead of sitting out of inventory while staff "airs them out."

A multifamily program Source-level treatment in the offending unit's exhaust path, combined with corridor and stairwell dispensing to neutralize the migration route. Buildings stop being trapped between a resident who won't stop smoking and a dozen who can smell it.
