19.75x21x1 Air Filter

Filter King 19.75x21x1 air filters are a part of the necessary filtration process that clean up incoming airflow. The process is necessary for a reason, airflow pumped in by your system is fresh but not always clean. The air surrounding your home may have allergens and pollutants that are able to make your home unsafe or uncomfortable when brought inside. The filters capture these particles in a tight mesh weaving that also allows clean airflow to pass and raise indoor air quality. Over time, the air filters will continue to clean airflow, but they will become dirty themselves in the process.

Your air filters become less effective over time as the particles they have captured begin to build up over time. Dirty air filters are not able to allow air to pass through easily, which means that there will be problems with the air inside when it is unable to cycle out of your home. Without fresh airflow, the air inside of your home will begin to stagnate and dry out over time. Your air systems also face issues where the dirty air filters in your systems cause mechanical issues and a rise in energy billing over time.

Your air filters require consistent maintenance in order to keep airflow coming in and reduce unnecessary billing. Filter King 19.75x21x1 size air filters are in stock and ready to help keep your home irritant free. We are able to deliver the replacements right to your door, regularly if you choose to use our subscription option.
