Heating Up a Home: Furnace Filters and What to Know

The average home furnace filter has the important task of keeping the air you breathe clean. But it needs frequent replacement before several issues begin to pop up.


The temperature inside of your home is often heated up by using a furnace to warm up brought in the air. The system brings in the air before it is pushed through flames, taken through the filter, and then distributed via the blower fan. The process is simple and allows the incoming air to be heated to the appropriate temperature dictated by your thermostat. However, the air filters in a system will not last forever and do not ever stop trapping and containing allergens and pollutants. The filters eventually become so dirty that they are unable to properly process airflow. 

Facts About Furnace Filters

The furnace filters in a system are there primarily to make sure that the air coming through a system is kept clean. This is necessary since the air inside your home should be distinctly different from the air outside. The air filters make sure the air quality rises and it becomes safer to breathe. Not all 16x25x1 air filters for systems are rated on the MERV rating system, which allows you to see just how effective the filters are. However, you should be aware of the dangers of having the ratings for your air filters be too high since they are similar to the issues caused by dirty air filters.

The airflow in a system needs to flow through the furnace without stopping in order to prevent the heated air from building up. However, as the air filters begin to gather particles and trap irritants, their mesh weaving soon becomes covered and unable to process the airflow. Tight mesh weaving causes the same problem, which means you want a filter that has a more average rating in order to let air flow through more easily. The best way to prevent any incidents with airflow is to replace your filters regularly, as often as monthly depending on your home’s environment.

Changing Old Filters for the New

In order to keep airflow coming in smoothly, the old air filters will need to be swapped out regularly. You can do this easily by ordering new filters of a similar size, which is detailed in your furnace owners manual. If you do not have the manual, try checking the old filters cardboard edge for the sizes needed. Once you know the dimensions required, ordering is a simple task and the filters are usable upon their arrival at your home.

Once you swap out the old filters you can put the new one in and watch as it immediately begins working to clean up the air coming into your home. Be sure to gauge how quickly the air filters become dirty so you can make a replacement schedule that best suits your budget.
