RZ Mask Good As N 95 Mask?

Down to 0.1 microns.

Coronaviruses are 0.11 microns - so perfect. Maybe even better than N95.

They are not cheap.

May be ok for you, all the UKs are imports from the USA.

Which ones, Chuck? RZ, N95 or all of them?

We need answers here Chuck.

1. Which masks need to be professionally fitted? N95 and FFP3 masks all have videos telling you how to fit them and how to test if you have fitted them correctly. I can't find one for RZ masks. What else do we need to know?

2. What else do we need to know to wear them safely?

3. I believe how you take off the mask is as important (Don't touch the filter part, remove with straps and bag/bin without touching). Any idea where we can learn that - if there is more to learn?

4. Do you know of anywhere we can get a tutorial?

Also a great question.

Here is another: Which are better, valved or non valved?

I have two types of N95 with and without valves. I plan on only using if I HAVE to go out . But you have good questions.

Pinned this post. Not sure masks will help, but worth knowing.

I have given myself 2 choices. I have N95 masks and full face CBRN gas masks from MIRA Safety. I had been looking at them for some time but this put me over the edge.  I will say the RZ masks look alot more comfortable.

I wear glasses so a gas mask is not for me because of the cost of glasses for the mask. That is why I have gone now with three different types of N95 Masks.

Carbon, I have done a bit of reading on masks (mostly with the data sheets and research 3M provides - they are an excellent resource if you look for them on their website. I'm sure they'll provide you with the answers you seek. There was even research posted about extended use of respirators, growth of bacteria and viruses, keeping clean, proper fit, handling, etc. with biohazards. One thing to be cautious about re-use is the growth of bacteria (especially with moist respiration) on the inside of a mask/respirator, which could potentially make one ill. There's a lot of mention of storage in cool, dry places, avoiding sunlight, etc. While some filters are designed for extended use (P100, for example), and about how filters even as the "get use" become better filters (blocking more particles), others are more single-use.

Well, the CDC FAQ was interesting.

I learned two more things.

Those pictures of staff with respirator marks left on their faces, were not necessarily due to the length of time they were worn for, but because THEY NEED TO BE REALLY TIGHT!

"Check the seal." as the instruction goes on the videos, does not cover how tight said seal must be.

The other thing was, valved is better (Unless you are doing surgery!) It is easier to breathe, the mask stays dry longer (vital!) and the protection for the wearer is as good.

Oh! and shave your beards, men!

Told my son he would have to shave. He knew that but I made sure he remembered.
