I got one hepa filter mask from Etsy that has ties and also ordered hepa filters from Etsy. This particular person at Sewn
Adventures store also wears Behind the Ear heading aids. I ended up modifying that one because the ties were annoying and bought thin elastic for making jewelry at Michaels. I found that because this type of elastic is so thin the loops fit beautifully behind my ears...aids on first and then the loops behind the aids.
Etsy is making a ton of masks...I only wanted a USA made one and she shipped fast and will custom make as many of the Etsy stores do. She has friends who wear CIs and is making masks for them. You can choose such cute patterns too. You can narrow down the selection if you type in face masks for hearing aids or just type in face masks and go to town...there are so many.
I now have 2 with soft elastic loops that I can wear comfortably and one with ties.
