How to Use Vented Dryers Without External Vents

David Young

It’s not always easy to find a place to vent your dryer. If you live in an apartment or basement, you may have no access to an exterior wall to run a vent through. With an indoor vent, you can vent your dryer inside your home. The vent uses a water-filled trap to help collect stray lint.

Use vented dryers without external vents to help reduce heating costs.

As an added bonus, the heat and humidity created by your dryer will help make your home more comfortable in the winter.

  1. Place a hose clamp around one end of a vent hose. Slide the end of the vent hose onto the exhaust outlet on the back of your dryer. Hold the hose and clamp so the hose is between the clamp and the exhaust outlet. Tighten the clamp with a flat-head screwdriver until the hose is securely attached to the outlet.

  2. Place a clamp on the other end of the hose. Slide the hose over the inlet on the top of an internal vent. Hold the hose, clamp it in position and tighten the clamp.

  3. Position the base of the internal vent near the dryer, in a position where it will have unobstructed airflow and won’t be kicked or knocked over.

  4. Pour one or two inches of water into the base of the vent. The water will help catch small particles of lint, keeping them out of the air and off of your furniture.

  5. Place the top of the internal vent on the base. Line up the locking tabs and press down on the top until it snaps into place.


Always keep water in the internal vent to capture lint. Clean the captured lint out of the vent frequently. Some internal vents include brackets for wall mounting. While not necessary, wall mounting can help keep the vent from tipping over or falling.


You must never use an internal vent with a gas dryer. Gas dryers produce dangerous gasses during the drying cycle, and those gasses must vent outside of the home. Never use a gas dryer with an internal vent, a damaged vent or an otherwise obstructed vent.

During summer months, the extra heat and humidity can cause mold and mildew problems in poorly ventilated areas.
