High Volume Suction Comparison

This side by side edit recorded by Prof Ross Hobson shows both images (with a laser to highlight droplets) and the particle meter placed 30cm from the mouth recording particles at 10 and 2.5 microns in micrograms per m3.

You can see the significant difference when high volume suction is used!

Many thanks to Jim Sykes for loaning the surgery and being the ‘crash test dummy’
