I have upgraded from the Type IIR surgical mask I was wearing previously, to a better fitting and higher filtration Cambridge Mask Company 'ventilator' or 'filtering face piece' (FFP) mask. This is also reusable for up to 340 hours, so avoids the plastic pollution involved in single use masking.
The filter technology is designed by the British Ministry of Defence, filtering out nearly 100% of all harmful air pollutants, gases, allergens, smog, and pollen; 99.7% of bacteria and 99.6% of all viruses - including Sars-Cov-2, the virus which causes Covid-19.
The 'FFP2' standard is equivalent to the N95 standard used in the USA.
As this is much better protection for me from aerosol transmission, particularly in combination with clients wearing face coverings as well, I am now able to spend more time on close up work around the neck and shoulders.
