How to Get Weed Smell Out of an Apartment
Cannabis smoke contains the same terpenes and combustion byproducts that cause the lingering smell — these settle onto every fabric surface, porous wall, and soft furnishing in an apartment over time. A single airing-out rarely solves the problem. Eliminating the smell requires removing the absorbed compounds from surfaces and improving air quality.
Step 1: Ventilate
- Open all windows and create cross-ventilation for several hours
- Run bathroom exhaust fans and kitchen range hood to pull air out of the space
- Place fans in windows blowing outward rather than inward to actively exhaust the air
Step 2: Address Fabrics and Upholstery
- Wash all fabric items that can be laundered — curtains, throw cushion covers, blankets, couch covers — in hot water with an enzymatic laundry detergent
- Sprinkle baking soda on carpets, rugs, and upholstered furniture — allow 2–4 hours, then vacuum thoroughly
- For upholstery: spray with Febreze Fabric or an enzymatic odour eliminator spray, allow to dry
Step 3: Clean Hard Surfaces
- Wipe all hard surfaces (walls near smoking areas, ceilings, windows, woodwork) with a solution of 1 part white vinegar to 2 parts water
- The acetic acid neutralizes many of the volatile compounds that cause the smell
- Pay special attention to the ceiling — smoke rises and deposits heavily on ceiling surfaces
Step 4: Activated Charcoal Bowls
- Place bowls of activated charcoal in affected rooms for 48–72 hours
- The activated charcoal adsorbs volatile organic compounds from the air continuously
Step 5: Air Purifier
- A HEPA + activated carbon air purifier run continuously in the apartment for several days after cleaning will remove remaining airborne compounds
- The carbon filter specifically targets VOCs including terpenes
