Pros and Cons of Using a Backdraft Damper

If you’re seeking a way of enhancing the quality of your indoor air, why not try a backdraft damper? It is a useful device that is fitted into the duct system of a house. It allows airflow in one direction only while preventing air from outside coming into the house. The blades in the damper may be activated by gravity or special springs to allow air to flow through in one direction out of the house.

Below are the advantages and disadvantages of using the device.

Pros of Using a Backdraft Damper

The damper performs its role quietly which makes it a convenient household device. Most of the backdraft dampers available on the market are easy to install. You can easily fit one into your vent system using minimal labor and time. This gives you savings as you are spared from having to call in a professional to do the installation.

The dampers are also available in various sizes which makes it easy to find a perfect fit for your duct network. The backdraft damper is well manufactured which assures you of excellent service. The springs, metal gauge and other components are well assembled to produce a nice sturdy unit. The damper does not easily deform or break.

Backdraft dampers are a highly versatile feature in household ventilation. They effectively keep cold air outside from infiltrating the house, particularly during cold weather. The vent motor of the damper is a great feature for improving household ventilation: if cooking odors become unbearable or household air gets stifling, simply adjust the vent motor to a higher level. It can also be used to balance pressure in different parts of the house.

With the various household heating features available in most homes, backdraft of air is a frequent problem. The damper helps to release hot air from the various heating sources within the house while preventing a backdraft. It is a convenient feature for improving air flow in the chimney, attic, laundry room or furnace room where air often becomes stifling. Sometimes the air indoors may get stale or musty, especially if the house has been unoccupied for a while. This may happen when the house is vacated during vacationing. Or perhaps you have a couple of rooms in the house that are not used much. The damper works well to freshen up stagnant air indoors while preventing a reverse flow into the house by outside air.


While the damper may be helpful in keeping cold air outside, this may be limiting when cool air is welcome indoors. This is because the damper is designed to facilitate air flow in one direction only: out of the house. The damper cannot help harness cool air when it occurs during the summer.

In addition, the damper has to be incorporated into the household vent system in order to work. Should you have to change your vent system, you will be compelled to get an appropriate damper.
