Air filters are an essential yet often forgotten part of your HVAC system. Commonly made of spun fiberglass enclosed in a cardboard frame, their purpose is to catch impurities in the air. They prevent dust, dander, and bacteria from flowing through your system, decreasing the quality of your indoor air and possibly causing irreversible damage to your entire system.
Changing your filter is a simple maintenance practice that usually only takes about 3-5 minutes to complete. To make sure your indoor air quality is as fresh as it is outside, we have outlined a list of steps to walk you through this straightforward process!
Steps To Changing Your Air Filter
- Locate The Air Return Vent
The filter is typically located in the air return vent. These are commonly found in hallways, stairwells, or a ceiling in an open area. Return vents are typically larger than supply vents and will be sucking air in as opposed to blowing it out.
In some systems, your filter might be located in a slot above, below, or on the side of your indoor HVAC unit. You may need to open a small, narrow panel to access it.
- Turn Off Air System
Once located, turn off your system. This will eliminate the chance of any dust or impurities entering during the replacement process.
- Remove Filter
Open your vent and remove the air filter. We recommend doing this carefully to make sure the debris accumulated does not accidentally fall off and get inhaled.
- Insert New Filter
Before installing the new filter, make sure it is the right size. Air filters usually have their dimensions printed on them but if they don't, measure the length and width of the filter previously installed.
Filters have arrows printed on them to show which direction they should be placed in the vent. Make sure the arrows are pointing toward the inside of the vent (or toward the direction air should be flowing) for proper filtration of air flow; if installed upside down your system will have to work harder to pull air through. This can result in higher energy bills and possibly damage your system.
- Add to To-Do List
Once the new filter has been installed and your system has been turned back on, make sure you add this simple chore to your monthly to-do list!
