An air breathing filtering system includes a housing having an air input and an air output, a first filtering stage that filters out particles from a first air stream to generate a second air stream, and a second filtering stage that filters out germs from the second air stream to generate a third air stream, wherein the second filtering stage uses a different filtering process than the first filtering stage. The first air stream is received at the air input and the third air stream is discharged outside the housing at the air output. The second filtering stage uses a liquid to disable the germs from the second air stream.
