If you install the filter in the wrong direction, air will struggle to flow through the filter material and your air handler will have to work overtime to compensate for the loss of airflow. Not only is this a waste of energy, but it can also damage the air conditioner or heating system. Beyond the cost of improper filtering, you are likely to suffer from a decline in indoor air quality. The filter is designed to remove a large amount of unwanted debris, but only when installed in a certain direction.
If you place the filter backwards, the normally collective end of the device will not face the air supply. In fact, the filter will help keep debris in the air. So what happens if the air filter is improperly installed? air filters are built to be installed in a certain direction. Installing the air filter backwards can restrict airflow through the air cleaner, cause the filter structure to fail, and allow dust, dirt, and other debris to pass through the filter and accumulate on the evaporator coil.
If the evaporator coil becomes dirty, the system will not operate at optimal efficiency and could clog the condensate discharge line and cause the system to fail. Air quality within the living space suffers when an oven filter is incorrectly installed. The filter also cannot capture dust particles when air moves through the filter in the wrong direction. Unwanted debris ends up floating in the air in the house instead of being trapped by the filter.
The biggest damage that can result from a filter installed upside down is that it can damage your HVAC system and reduce its life expectancy. An AC filter installed upside down will greatly slow down airflow, your oven will have more difficulty operating. When efficiency decreases, the likelihood of a system failure, such as a refrigerant line leak or a failed compressor, increases. A furnace or central air unit that has to draw air through the non-porous side of a filter loses efficiency and runs longer, requiring more energy because it slows down the flow of air through the heat exchanger, according to Bob Vila.
They keep unwanted debris and sediment out of indoor air and help keep the system running smoothly for years to come. This allows the filter to effectively trap particles in the air while minimizing deceleration of airflow through the system. When a filter is installed in the wrong direction, it can quickly become clogged with dust, pollen, dander and other particles. When the filter is installed upside down and starts to prevent air flow, air may begin to circulate around the cardboard frame of the filter, which is not that difficult to do.
Air filters have direction arrows to indicate in which direction to install the air filter on the return. It's a common misconception that using an air cleaner with a higher MERV (Minimum Efficiency Information Value) rating is the best way to do this. In fact, they warn that constantly turning them upside down as their seemingly worse half could result in their system not blowing air at all. In addition to looking at the direction arrows, all air filters are built in a certain way depending on what type of filter it is and how long it is designed to last.
Since the air in your home is permanently recirculated, dirty ducts can mean moldy smelling air and a lot of extra dust. Therefore, if you are using your air conditioning system, this layer of dust can significantly affect its performance and prevent airflow. Having an inverted HVAC filter can cause system damage, mold problems, poor indoor air quality, and other problems. If you unintentionally install that filter upside down, the air will hit the fine-pore side first, before it has a chance to enter the filter.
Particles are also allowed to accumulate unevenly, causing the oven to work even harder to extract air. .
