Cannabis smoke carries oily terpene resin. Resin is sticky, so it lands on upholstery, drapes, painted walls and the inside of return ducts and stays there long after the room clears.
Why airing out fails
Ventilation removes airborne particles. It does nothing to the film already deposited on materials, which is where the smell has been living since day one.
The materials that matter most
Fabric furniture, mattresses, drapes, carpet, and the HVAC return. In smaller units the return is usually the reason the smell reaches the hallway and generates complaints.
Turnover timing
We schedule around your make-ready so the unit is neutral before the next showing. Short re-entry time — we'll tell you exactly when it's safe to return.
The short version
- ✓Resin is a film problem, not an air problem
