So...do we have reusable respirators that block >=95% of particles 0.3 microns in size yet??

[–] [email protected] 11 points 6 months ago (1 children)

Yeah, there are plenty of P3 and N95 filters for reusable respirators, here are some for the 3M 6000 mask series:

Don't those use disposal filters?

Mate there’s no such thing as washable healthcare items unless it can survive an autoclave lmao

(In the context of infection prevention and sterilization)

So?

You still reuse the respirator

That still uses disposable filters. So maybe it reduces the amount of waste by 10%?

Do we have one that has reusable filters? I mean a filter you can use for at least 10 years.

I mean, use for 10 years by what metric? A woodworker is gonna block up that filter in a few months, someone who works in a hospice might get a few years, and triage nurses might burn through them in half that simply due to moving fast. Also I think 10 years might be a bit of a stretch in general, I've never known a mask filter to last that long in any model I've used

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.

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.

Create a copper/silver mesh that is 3 micron and breath to your heats content.

[–] [email protected] 1 points 6 months ago (1 children)

Does something like that exist?
