Using an air filter that is too small for your HVAC system can have serious consequences. Not only will it not do its job properly, but it can also lead to air quality problems. When an air filter is too small, dust, mold, and other contaminants can pass through the gaps and be thrown into the air. This is why it is important to make sure that the filter you use is the correct size for your system.
If you cannot find a standard size filter that fits your system, you may need to order a custom-sized air filter. It is important to note that the air filtration industry standard is to make filters slightly smaller than their slot or frame, so they can easily slide into place without bending or breaking. When buying an air filter, you should also consider the MERV (Minimum Efficiency Reporting Value) rating. A higher MERV rating means that an air filter is more effective at removing smaller particles from the air.
However, it is important to remember that dense filters will naturally filter more dust out of the air and will not need to be replaced as often as other types. Your unit may not have the suction power to properly filter air entering and passing through the system. It is also important to clean or replace your air filter frequently. This will help remove debris and other particles that can pollute the air and improve your home's air quality. HVAC service companies typically offer air filter replacement services in addition to system repair and unit installation services. In conclusion, using an incorrectly sized air filter can have serious consequences.
It is important to make sure that you buy an air filter that fits your system correctly and has a high MERV rating. Cleaning or replacing your air filter regularly will help keep your home's air quality safe and healthy.
