Good to see you too, Beverly! Not on as often as I'd like but I do check in fairly regularly, not posting as much...

I am making masks for our local hospital and working with an Anesthesiologist on what they need. I have bought Home air filters (like for your heater) to use as the filter - the box will be cut away and the filter taken apart and laid out flat like fabric to cut a pattern a tiny bit smaller to go into the mask. The filer has a MERV rating of 13, most home filters have a MERV 9-11 rating and are considered excellent. If you put a filter in - put a note on it that says what the manufacturer and rating is.
They have asked me to leave both sides open so they can "reuse" the N95 masks and slip them inside.
A few other ideas:
Make one side light and the other dark - that way they can be sure to use them consistently.
If you can't get elastic - use a t-shirt- cut a 1" strip off the bottom of a t-shirt. Make one cut and you will have a great no-sew tie
The wire at the nose - I used 18 gauge, 10 lb aluminum wire - cut 3 1/2" long and the ends curled back to the wire (no sharp edges) - the hospital was cutting up pie tins!, paper clips broke easily, and this wire molded to the face nicely.
In the picture you can see the long tie slides through the opening on the side of the mask.
I put batches of 10 masks in a plastic bag, with a label if they have filters, note manufacturer and how they rated it or that there are no filters

The pattern is easy and there is a tutorial at Sewitonline.com if you have questions. Be sure to watch the how to with the Serger. It is easier and the masks can be made in about 10-15 minutes. TQS also posted a blog with more options. Good Luck!

My son-in-law is a doctor and he sent me the courier press.com site with his request to make some. It has a very simple pattern and does use elastic. Another doctor friend said that they will wash them using the sanitize setting. These don't have to last forever as Hanes and probably some other companies are re-tooling to make them. This is a perfect way to clean up your stash while feeling useful and utilizing our time wisely. God bless everyone!

Thank you for your reply, Renata. That is the length I will use. I'm so very happy to see you on the Forum again!

I made my ribbons 17 inches. Janet

If you would like to make masks for my in-law and her co workers at the provendenve hosp in Seattle area I would be glad to mail them.
They work in the ER and helicopters.
Didn’t want to put her name and address here.

I will try the 16 inches and see if it ties around my head. I'm going to work today, will ask the nurses if ties will work for them. Kathy

Just measured the individual tie on the only disposable mask I have from last year unused that was given to me at the hospital... 16 inches. Hope this helps!

Kathy, what length are you making your ties? I don't believe elastic will hold up to the cleaning of these masks - chlorine or non-chlorine bleach, so am using ties for my daughter-in-law. I'm guessing about twelve inches? Would love your input.

The hospital I work at in California also needs face masks, I want make some but the link they gave us www.deaconess.com/How-to-make-a-Face-Mask, calls for elastic which I don't have. I will have to ask if ribbon ties would work for them.

My sons sil works at this hospital and has asked me to make masks. I use cotton fabric and ribbon ties, ( long) so they can ties them behind their heads. I don’t have the hospital kits, this hospital is in Washington state.
Hope the link works. I live in Missouri.
Masks could be sent to the hospital, but call first to see if cotton masks would be accepted. Some nurses are using them to cover their N95 masks because they might need to reuse them.
