Step Two: Check Your Ventilation

If you’re using your heater in a poorly ventilated room, the cold air blowing out of it will be more noticeable and uncomfortable. Make sure that there is enough space between the heater and any walls or furniture obstructing its ventilation path to allow fresh air through.

You can also try moving your fan heater closer to an open window to let the cold air out and warm air in; just be careful that it doesn’t get knocked over!  Consider installing an indoor grill in the window so that you can keep it open while keeping your heater safe. Even if the heating is on full blast, a well-ventilated room will stay relatively warm, so this is a good alternative in winter!

Step Three: Check the Filter

Your fan heater may be blowing cold air because its filter is blocked with dust or grime. Please turn off your fan heater and remove the filter by pulling it gently forward. If any dust falls out, use a vacuum cleaner to gently pick it up before replacing the filter into place.
