For a significant health issue, the extra cost seemed warranted.

Steve, thank you for your thoughtful reply.
I did not realize that the Dylos monitors reported particulates as micrograms per cubic meter. I was under the impression they only tallied particulate counts by size category.
In the USA, OSHA regulates wood dust as ¡°Particulates Not Otherwise Regulated (PNOR)¡±. Total particulates are limited to 15 milligrams per cubic meter, while the respirable fraction is limited to 5 milligrams per cubic meter. The Permissible Exposure Limit is a Time Weighted Average, which I do not completely understand but takes into account the amount of time a person is exposed to the dust.
If Dylos reports mass of particulates per cubic meter, perhaps I can relate those readings to health and safety standards.
Which Dylos model do you use?
