Furnaces are essential, especially for those who live in cold regions. It is necessary to replace the air filter of the furnace unit all year round. The filter accumulates dust and debris that could otherwise get into the furnace unit and cause severe problems. It does this job pretty well, but it has one major downside – it can’t clean up the debris it collects. Therefore, you should replace the furnace filter every 1-3 months.
What Happens If You Forget To Change Your Furnace Air Filter?
When you fail to replace your air filters regularly, they become clogged due to the aggregation of particles and pollutants adhering to the filter. Although the filter helps to accommodate these tiny objects, the build-up creates an almost impenetrable barrier so that air cannot pass through completely, which can ultimately cause more problems for the furnace.

The purpose of the furnace filter is to accommodate and prevent the amount of dust, pet hair, and other allergens in the house. Passing air through a dirty filter can increase, rather than reduce, these allergens can cause unwanted reactions in people at home. Often the air outside the house is much cleaner than the air inside, which can be of particular concern to those who already live in areas with poor air quality. It is also a huge concern for those who suffer from allergies and respiratory problems.
If the air filter is blocked and cannot preserve pollutants like it used to, these elements can end up in the air everyone breathes in the house. Immediate problems can include headaches, itchy eyes or throat, and dizziness. If you fail to change the filter on time, and the problems persist, the long-term effects could be respiratory or heart diseases.
If the furnace filter is not changed often, it will eventually become clogged to the extent that no air can pass through it. When the furnace is on, the lack of air circulation will trap heat in the unit. As the temperature inside the system increases continuously, the limit switch will activate and turn off the furnace to prevent it from overheating. Without a replacement of the furnace air filter, the furnace will overheat every time it starts again. That is called short cycling.
