HEPA filters don't have to have more restriction, they often have more material to keep airflow the same.

the question was will a hepa filter have more restriction and will the blower motor handle it.

A concern was expressed that medical professionals will carry things on their person.

so a better filter will catch more airborne particles... clearly

you got contaminated people in your car? wipe down the surface with antibacterial wipes also

you get a hepa filter to filter finer particles, not to last longer
