Proper ventilation in your living area may prevent illnesses and reduce transmission of viruses. But can portable air cleaners and purifiers fight COVID-19 and flu viruses? Dr. Gregory Poland, a Mayo Clinic infectious diseases expert, says that they generally can.
The more air exchanges and cleaner the air, the lower the risk. That means using a HEPA filter to clean the home air. Portable air filters are designed to filter the air in a single room, though they cannot remove all air contaminants. A HEPA filter catches those virus particles and hold them there. A filter must be changes at intervals since the filter does not kill the virus, but rather it exchanges cleaned air more rapidly to get rid of the virus.
With a HEPA filter, it’s being attached electrostatically to the filter itself so that it cannot be circulated in the home air. That is why changing the filter and changing them properly is so important. Of course, you should also continue face-masking when with others, social distancing and using hand sanitizers.
