Will a HEPA filter catch mold spores?
Mold spores can vary tremendously in size, but the size range is generally between 4 microns up to about 20 microns (Li et al., 2011). This means even the smallest mold spores fall well within the HEPA specification, allowing a HEPA filter to trap most mold spores that pass through them.

How do you test a HEPA filter?
The HEPA filter integrity test is typically performed on supply air or exhaust air HEPA filters using a photometer to scan the filter surface for pinhole leaks that could allow the transmission of contaminant particles that would be unacceptable in a critical application.
Can HEPA filters be washed and reused?
HEPA filters use various fibers to trap dirt, dust, impurities and allergens in the air. They are commonly used in air purification systems or vacuum cleaners. Cleaning the filter and removing the buildup can restore the life of the filter and allow it to be reused.

The particles will create a barrier in the air filter and prevent air from passing through, which could damage your HVAC system or make it less efficient.
Are HEPA filters dangerous?
