Air Mode: Tips to Replace the HEPA Filter

The current pandemic has raised awareness and questions centered around best practices to follow for
air filter replacement. Here are some recommended steps to replace an air filter:
1. TURN OFF THE POWER for safety. Also, turn off any fans in the area at least 20 minutes prior to
servicing a filter.
2. Wear personal protective equipment (PPE): This includes a face mask, nitrile gloves, and shoe
covers.
3. Remove the old filter. Simply slide it out of the slot that holds it in place.
4. Check the condition of the filter. Does it look clogged with dirt and dust? Many factors
can impact how fast a filter will become clogged, shortening the life of the filter.
5. Replace the filter. Immediately place the old filter into a plastic bag being careful not to shake
or drop it. Sudden movements can cause microscopic particles to be released into the air. Twist
or tie the bag shut and consider taping it to create a seal. NOTE: If the filter has a permanent
frame, the media should be removed outside. Be sure to dispose of the old filter in an outdoor
trash can.
6. Insert the new filter right away. An arrow on the filter's frame shows the direction that air
should flow through the filter, which is always away from the return air duct and toward the air
handler mechanism. When inserting the filter back in the housing, make sure that arrow points
away from the return and toward the air handler. Write down the date you replaced the filter.
To maintain healthy breathable indoor air, standard HVAC air filters should be changed at least every
three months. In some situations, the filter may need to be changed more frequently. Changing an air
filter on a regular maintenance schedule also keeps equipment in top working condition, prevents
breakdowns, reduces energy consumption, and limits expensive repairs.
Extra safety cushion provided by the internal UVC lamps
The HEPA filters in this AIR Unit are irradiated continuously by the UVC lamps above the HEPA filters.
So, in general, most of the dangerous pathogens trapped on the HEPA filters have been inactivated
before the technicians replace the HEPA filters. However, the UVC light can not penetrate the dust and
particles, so if some pathogens are hidden underneath the dust and particles and were not irradiated by
the UVC light, they might still be dangerous to technicians.
