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 -
In addition, the now standard HEPA filter for the Praetor jets can capture 99.97% of bacteria, viruses, and fungi — further providing fresher, cleaner air inside the cabin. So when you fly on an Embraer business jet, you can breathe easy.
