Hi,
I have a novel HEPA/carbon filter concept that has not been done but should work quite effectively.
I propose an internal HEPA filter using a slide in fixture to locate the filter over the vent
This will enable stock carbon filter to be retained, and the sequence of filtration will prevent the HEPA being clogged with carbon particulate.
I am interested in finding a more skilled designer to collaborate with me.
I’m in Australia but flexible in hours to get on Skype or teams etc to discuss and work on it.
