Key takeaways
- Wet wood is the biggest cause of smoke.
- Hot, well-fed fires smoke less than smoldering ones.
- Airflow and pit design make a big difference.
- Gas removes smoke almost entirely.
Smoke is unburned fuel
Smoke is the visible sign that wood is not burning completely. Wet wood, low airflow and smoldering coals all produce it. Fixing those fixes most of the problem.
Dry, seasoned wood
Seasoned hardwood with moisture under about 20 percent burns hotter and cleaner. Store it stacked, off the ground and under a roof for six to twelve months.
Build the fire right
Start small with kindling, add wood gradually and keep the fire hot rather than smoldering. Top-down fires can start cleaner and smoke less.
Airflow and design
Pits with air intake near the bottom and a good height-to-width ratio burn more efficiently. Smokeless double-wall designs push heated air back into the fire to burn off smoke.
When to switch to gas
If smoke is a constant problem in your neighborhood, a gas feature gives you the fire with almost no smoke. Many owners convert an existing pit.

Quick answers
Does a smokeless fire pit really work?
It dramatically cuts smoke once it is hot, but it still needs dry wood and a good fire. A cold start can still smoke a little.
Which wood smokes the least?
Dry hardwoods like oak, hickory and ash burn cleanly. Avoid green wood and resinous softwoods when smoke is a concern.
