The most opportune time to change a furnace filter

Furnaces are usually turned on high during colder months. Changing the furnace filters on time is necessary to keep the heating system running in good condition. Here are some of the benefits of timely replacement of the furnace filters:

 

A clean filter allows conditioned air to flow into your home. Filters also trap already existing pollutants from indoor air.

A clogged filter restricts proper airflow. An insufficient flow of clean air can make indoor air to become stuffy. This can be a huge problem especially when you have guests over at your house.

Poorly maintained filters cause unwanted particles to build up on the heater’s components. This interferes with the overall performance of the heating system. Replacement of furnace filters at the right time ensures that the heater will last longer and with lower maintenance.

Some locations are dustier than others. If your home is more prevalent to dust from the immediate environment, then you might need to change the filter more often.
