While there is some evidence that HEPA rated dust filters can capture viruses floating on droplets smaller than 5 micrometers in the air, it is important to understand the context.
Source capture dust/vapour filters are designed to capture within a specific working zone. A vacuum cleaner won't suck up dust 2m metres away, for example. This means it is highly unlikely to capture all of a clients breath, coughs or sneezes.
To my knowledge, no source capture system manufacturer has either tested their products for virus control or explicitly states their effectiveness with regards to COVID-19.
Will they help? Probably. Should ever salon use one to breath air free of dust and vapours? Absolutely.
There are many other important things nail salons need to do to protect themselves first:
- wear n95 / FFP2 mask that is from a trusted source. There are a lot of fake masks coming from China.
- replace the mask after each client in case it has become contaminated. Learn how to remove safely.
- clients should wear washable cotton masks or single / three ply medical masks
- Nail Techs should wear nitrile gloves and either safety glasses or head visor
- practice excellent sanitation and disinfection. Consider everything a client can touch from entry to exit. Control where they put their hands and don't allow mobile phone use.
- Ensure they wash hands properly and they apply liquid sanitiser.
- If they touch their face or any surface during the service, apply sanitiser on the hands again.
Hopefully by the time nail salons are open, a working protocol will have been issued.
Bear in mind that 10% to 12% of healthcare workers become infected, despite having PPE and being trained in it's use. The challenge for all of us will be to avoid infection by contact and maintaining sanitation standards long term, without lapse, until the threat no longer exists.
One other point. It is highly unlikely that salon insurance would provide cover if a salon client became infected. Check this with the insurance company.
If not, each client should probably sign a liability waver to ensure the salon is not held liable. Take professional legal advice.
