Do small business jets (Phenom 300 for example) have HEPA filters for recirculated air? Or don't they recirculate air at all?

Embraer's own website confirms that their business jets can recirculate or draw fresh air, but HEPA filters don't seem to be an option until you get into the Praetor size and above.

  • $\begingroup$ Thanks for your answer! This information on the website seems a little confusing, since it does not specify if the recirculation exist in their smaller jets or if it's only a Praetor feature. It also seems a little strange to me to not filter at all the recirculated air. $\endgroup$ – Pedro Guimarães Aug 17 at 13:18
  • $\begingroup$ @PedroGuimarães: I would be surprised if they didn’t have SOME kind of basic filter for recirculated air. It just won’t be rated for hazardous airborne particles like HEPA filters are. $\endgroup$ – Aaron Holmes Aug 17 at 13:27
