If you don’t know how to switch the furnace off, call out your landlord or the manufacturer.

  • Locate the filter:

The filter is usually located inside the furnace or just inside the air vent. You can also find an arrow printed on the side of the furnace, showing the proper direction of the air flow.

  • Draw the Direction of the Air Flow:

Prior to removing the filter, mark an arrow with a sharpie pointing in the direction of airflow. This makes it easy for you to reinsert the filter in the right direction.

  • Slide the Filter Out of Place:

Once you’ve successfully found the filter, you can remove it. No special tools are required. All you need to do is grab the filter with your fingers and remove it.

Cleaning the Filter:

  • Make sure the filter is reusable:

  • Rinse the Filter Under Running Water:

Cleaning your furnace filter is not that complicated. Since you don’t require any special cleaners, you can simply rinse the dust, dirt and debris away with running water. Make sure to turn it around to get all sides clean.

  • Set the Filter Somewhere to Dry:

Let the filter dry one you’ve got it clean. It’s best set it down somewhere and let the air dry. Normally, the temperature of the home determines how long it would take to dry. Refrain from reinserting it in the furnace until the filter is completely dry.

  • Put the Filter Back in Place:

Once you’re done with cleaning and drying, you may want to reinsert the filter. Sliding it back in place is really not a big as it hardly requires any special equipment, either.

Look at the arrow your marked earlier and reinsert the filter in the right direction of airflow.
