In the Launch Event video, Elon goes into more detail around the 10 minute mark. The filtering is effective down to 0.01 microns. During testing, they were not able to detect any measurable level of spores, bacteria, or viruses in the air passing through the system. Two separate filters, and the main filter has three levels of activated carbon. First: Universal (hydrocarbons) Second: Acidic gases (sulfur) Third: Alkaline gases (ammonia)
