If you install an air filter in the wrong direction, it can be difficult for air to flow through the filter material and your air controller will have to work harder to make up for the loss of air flow. Not only is this a waste of energy, but it can also damage the HVAC system. It's important to understand the direction of the filter because air passes through it in one direction. Although both sides of the filter may look the same, one side is more porous to allow air to enter.
If the filter is installed incorrectly, your HVAC system will be subject to unnecessary wear and tear. To ensure maximum efficiency, it's best to place the filter near a window, door, or wall where air moves. It's also important to remember that filters need to be changed regularly as dust and other particles accumulate and reduce air flow. When installing a filter, you should look for arrows on the side that indicate the direction of air flow.
If there are no arrows, you can determine which way the filter should be installed by feeling which side is more porous. Once you know which direction the air flows in, draw an arrow on the filter with a permanent marker so that you can easily match it up when changing it. It's also important to note that people with pets should change their filters more often than those without pets due to the hair and dander they produce. Additionally, if you place your air purifier close to areas with lower indoor air quality, it can improve air quality quickly.
Overall, proper placement of an air filter can increase efficiency by up to 20%. Not only will this save energy, but it will also help keep your HVAC system running smoothly and efficiently.
