How to Remove an Air Filter?
To remove an air filter, first locate it, access its housing or vent, and carefully slide the old filter out, noting its orientation and size.
Removing an air filter is a common maintenance task for heating, ventilation, and air conditioning (HVAC) systems. Whether your filter is located in a return air vent or directly at the furnace or air handler unit, the process involves a few simple steps.
Air filters can typically be found in one of two primary locations:
- Return Air Vents: Often large vents on walls or ceilings where air is drawn back into the system. The filter fits directly behind the vent cover.
- HVAC Unit: Located at the furnace or air handler itself, usually near where the return air duct connects.
Step-by-Step Guide to Removal
Here's how to remove your air filter, incorporating insights from the provided reference:
Before You Start
- Turn Off System Power: For safety, it's advisable to turn off your HVAC system at the thermostat or the main power switch before changing the filter.
Removing the Filter
Once you've located the filter, follow these steps:
-
Access the Filter:
- If the filter is in a return air vent, you'll typically need to open the hinged cover. There might be small latches or clips holding it closed.
- If the filter is at the HVAC unit, look for a slot or panel where the filter is inserted. You may need to slide open a cover or remove a latch.
-
Remove the Old Filter: Gently remove the filter from its slot or housing. It should slide out relatively easily. Be mindful of any dust or debris that might fall off.
-
Note the Filter's Position: As shown in the reference, take a moment to note the position of the filter. Air filters often have an arrow indicating the direction of air flow. Make sure you observe which way this arrow is pointing relative to your air duct system. This ensures you put the new one in the right way.
-
Note the Filter's Size: Also, note the size printed on the side of the filter. The reference mentions a filter size like 20 by 25 by 1. This size designation (Width x Height x Depth, in inches) is crucial for purchasing the correct replacement filter for your vent or unit.
What to Do After Removal
With the old filter out, you have the essential information (size and correct air flow direction) needed to select and install the new air filter. Dispose of the old, dirty filter properly.
Changing your air filter regularly is a key part of maintaining indoor air quality and ensuring your HVAC system runs efficiently.
