Does Cleaning Your AC Air Filter Protect You From COVID-19?

COVID-19 came to change everyone’s life, and after several months of the outbreak, epidemiologists continue to learn new things about the virus.

We’ve learned how COVID-19 is transmitted: the studies and evidence suggest it gets primarily transmitted from symptomatic people, through respiratory droplets and contact with contaminated surfaces and objects. But now in summertime, you may wonder whether air conditioning can transmit COVID-19.

Although the WHO hasn’t accepted viral particles floating in the air can be infectious, some scientists claim they are. In reality, no one can provide an absolute answer. However, what we can tell about air conditioners is that when they aren’t properly maintained, and filters are not regularly cleaned, they affect the indoor air quality.

Air Conditioners Recirculate Air

Most air conditioners are designed to recirculate air. If the coronavirus is airborne, having old and dirty AC air filters could expose to high concentrations of the virus and worsen the symptoms of people who are already infected. One of the recommendations given to COVID-19 patients is to try to breathe fresh and clean air.

In theory, COVID or not, any other airborne disease or virus could make us sick, especially when sharing the space with several people. The best way to prevent allergies and respiratory problems is by guaranteeing good indoor air quality in our homes and offices. 

How Often Air Filters Should Be Cleaned or Changed

Air conditioning filters should be cleaned every two weeks. If you live in a dusty or more polluted environment, then weekly cleaning would be recommended.

Cleaning the filter is part of the maintenance all air conditioners should receive to decrease air pollutants and extend the AC unit’s life.

Changing AC Air Filters

Manufacturers usually recommend changing the AC filters every 30 to 60 days unless you live with no pets, and alone you could extend the time to up to six months. However, for preventive measures during this time, while cleaning, if you notice damage on the filter, don’t hesitate to replace it.
