A Serious Question to All Out There

From the "I Need to Know" category, can someone educate me about recirculated air such as on commercial jets, trains, etc. Are they highly filtered to reduce the spread of viruses?
If this is a stupid question please forgive. Your response could help me determine whether or not I should consider a future trip.
