When it comes to air filters, there are a few key factors to consider. The size of the filter, the type of filter, and the environment in which it is located all play a role in determining how often it should be replaced. Generally speaking, 14x18x1 air filters should be changed every 30 days if they are made of fiberglass, and every three to six months if they are pleated. However, if you live in an area with high levels of dust, you may need to check and replace your filter more often.
Fiberglass air filters are the more economical option, but they are not as effective at capturing dust and particles from the air. Pleated filters are more expensive but can last longer if replaced every three to six months. If you have young children in your home, you should change your air filter more often, once every two to three months. When selecting a 14x18x1 air filter, there are several factors to consider.
The type of filter, size, accuracy, material quality, and performance ratings all play a role in determining the level of filtration and the life of the filter before needing to be changed. Caring for these units is usually a relatively simple process. The best practice when maintaining any filter system is to check it regularly and replace it as needed. After a period of smoky days or poor outdoor air quality, inspect the air filter to see if it needs to be changed.
In smaller homes, the air conditioning system has to move less air, which may mean replacing air filters less frequently. If you follow the proper filter replacement programs, you'll enjoy breathing clean, fresh air and stay healthy.
