I’m referring to the pandemic. Use for 10 years by a nurse breathing average hospital air 40 hours per week.
I want something washable, not disposable.
Create a copper/silver mesh that is 3 micron and breath to your heats content.
Does something like that exist?
X to doubt
*now for only $199,999.95!
The 3m 6035 filter only has a replacement schedule for infection control reasons, implying the outside may become too contaminated.
It was the original pandemic filter (there is a model up that does organic vapours too), marketed as being used for at least one pandemic wave.
No filter will last 10 years of daily use, at some point even your washable car filters or cleanable air purifier filters clog up and break down. But these are very long lasting for what they do, and I can see someone being able to stretch them out to one every six months, if in a hospital setting.
