Using the wrong size air filter for your furnace can have serious consequences. The biggest concern is that it may not effectively prevent dust buildup on the motors and blowers of your HVAC system. This can lead to a dirty oven, which can affect its performance or even damage the internal components, resulting in costly repairs or replacements. It's important to check the size of your existing air filter before purchasing a replacement.
If you buy a filter that is too large, it won't slide properly in the slot. On the other hand, if it's too small, it won't cover the entire space and may allow dust and dirt to pass through. If you're unsure of the filter size you need, consult the manufacturer's specifications or ask your HVAC technician for help in choosing the right product. Bending the filter to fit will result in an imperfect seal, allowing air to filter through and around the curve, bypassing the filter completely. This causes dirt and debris to build up on the fan, slowing down airflow, degrading performance, decreasing air quality, and creating a mess that will require costly repairs or cleaning. An incorrect air filter can also reduce HVAC efficiency and increase heating and cooling costs.
If it's too dense, the heater or air conditioner may need to run longer to counteract increased air resistance. Too small a filter allows contaminants to build up on critical components, impairing performance. The right filter will improve your health and comfort without sending utility bills through the roof. Many homeowners don't change their air filters often enough. In these situations, contaminants penetrate the HVAC system.
In addition, an incorrect filter can block progress of air due to dust buildup inside it. This means that your system will have to work harder to move the same amount of air, resulting in inefficient cooling and contributing to respiratory health problems for your family. Be sure to visit the manufacturer's site or have your HVAC unit checked by a professional. They will also be able to recommend HVAC maintenance tips and the correct upgrades to your system for better filtering efficiency. Don't try to bend or trim an oversized filter yourself as it won't seal properly and air will leak through and around the curves. Using an incorrect air filter can cause numerous problems with your HVAC system, including lower indoor air quality.
It can also reduce efficiency and increase heating and cooling costs. If you moved to a new home or had someone change your air conditioner filters for you, make sure they used the right size filter. The wrong air filter won't necessarily damage the heating and cooling system itself right away, but it does reduce its efficiency, something you'll notice on your utility bills. To keep your oven running smoothly for a long time and ensure clean air for your family, clean and change the filter regularly.
