My Stark .3 micron filtering masks got here

The masks show up early. Here are my preliminary findings.


Pro:
The cloth is soft against the skin.

Filtering seems efficient enough to not feel too stifled.

Not too much material. I consider my head to be average size and it covers enough.


Cons:
There is no nose clip to make a solid seal surrounding the nose. This is the biggest weakness for me. The upper piece does adjust to touch the face but the martial doesn't appear to have the filtering martial. Without a solid seal, I would rather use the KN95 disposable that I can achieve a seal with.



Conclusion: I am going to order some aluminum nose clips for the mask. While I believe the mask well once I get a clip for the nose. For the price I paid, it is still a good value to get a washable .3 micron filtering mask. I will update once I get the clips.

I imagine it looks dorky as hell, but I posted about a study showing that using a cut stocking around the mask/neck/head really helps the efficacy and the sealing problem.

I am going to fold down that upper lip of fabric and attach a flat aluminum nose clip. It should pull the lower body of the mask that has the .3 micron filtering to close the seal on the face. That upper area has no filleting material, it is just the outer cloth this mask's covering is made of.

Looks like I will need something like this. How to attach it more permanently is going to be tricky.

Stitch the clip to the outer layer, or use silicone adhesive

Do you think this will hold up to a washing?

All you need is warm water and a little soap in the sink, or large bowl. If washing your hands for 20 seconds with warm soapy water does the trick, in the clothes washer is overkill, wouldn't you think? Surely not the dryer on hot.

I use a drop of liquid dish soap and a 1 pt reuseable plastic soup takeout container. Warm water, the soap, shake the heck out of it, let it soak for a few minutes, then rinse off really well. Dry by morning.

Those masks look decent but the lack of a nose bridge/clip is a little disappointing.

Unless one sneezes in the mask, or somehow spills food or drink, I'd think disinfecting it would be more important than washing it.

A dilute bleach solution, or hand sanitizer spritz and a rinse would probably be enough.

As for 'washing', a soak in dilute detergent and gentle rinse would should be sufficient, followed by air drying.

A stitched-in bridge/clip should survive that easily.

Any mask that can't stand up to two or three cycles of that should probably be considered disposable.


I'm just happy to see the supply of various masks has increased significantly.

The many stories of care givers and responders having to reuse a mask over and over were sad beyond words.

I spritz my KN95s with H2O2. Good enough for me.

I've ordered several of their masks. I like them except for the reason you stated. Sometimes my glasses fog, sometimes not. Very frustrating. Other problem is my big head, so it does tug my ears forward like Alfred E. Neuman. Of course, I see now that they're making adjustable masks.

I think the whole mask thing around here is going to become a way for people to also block the cold air, so I am curious about those that are thick fabric and have some sort of washable capacity. But, generally, I agree that washing is not as important as disinfection, and even then that is only important if you are in close proximity to other people for a sustained period of time.

I think hot glue on the nose clip thing may work. I had two N95 masks where the nose clip eventually fell off and I'm about to try the hot glue fix. I'll let you know how it works out.

That's exactly why I bought my first fabric masks, long before COVID.

Walking in the morning coolness was no problem except for breathing cold air.

I'd have to slow my breathing and thus my pace.

I got some fairly thick fabric masks, thicker than I thought they'd be, but also a little smaller, so when moving around, frequent adjustment is required.

They're not suitable for COVID if needed to be worn for more than a short time, or you have to speak to somebody, as they'll shift.

Due to the thickness, they do increase breathing effort slightly, and it becomes pronounced over time. But a little break without it and all's well.

As it's warm at any time of the day or night around here, my COVID masks suffice.

Re: washing vs disinfecting

The virus is encased in a lipid membrane. Soap (and water) dissolves that membrane which is why it is so effective in killing the virus.

The nose issue is what I encounters with the 38 Degrees masks I bought. Gap on either side and not much you can do. I might use it outdoors.
