Medical masks without cotton material?
August 29, 2022 1:13 PM
Hi. I am wondering if there are medical masks that are not made out of cotton material? This is due to a rare allergy. I have to wear a medical mask at my university this fall, but they require medical masks - it doesn't look like they will accept polyester made masks that are not medical.
I'm not aware of any cotton medical masks- both surgical masks and N95s, etc, are made from synthetic material.

@pinochiette are you able to provide links to such masks without the cotton material? Because some have cotton lining.

I don't think it's even remotely common for surgical masks to have cotton linings. Here is an example.

@nat - Good to know. Do you happen to have any links to the ones without cotton linings or hot air cotton material?

3M Aura masks don't list any cotton parts.
I'm sure the OP knows this but for others, "hot air cotton" is a fairly common component of the meltblown filter layers in masks - I don't think a cotton lining is common but an inner layer that contains some cotton is not unusual.
It would probably be helpful to know what your school's definition of a "medical" mask is.

@ mskyle - that is a good question. It is rather broad as it states: All masks worn must be medical grade. The school will provide medical masks and KN95 masks it states.

These 3-layer procedure masks say "Masks are 3 layers ultrasonically welded together: 2 Spunbond Polypropylene layers outside; 1 Meltblown Polypropylene filter layer inside." They have other masks that appear to be all-polypropylene.
Likewise this company only lists polypropylene in its Surgical Grade Face Mask.

Does "hot air cotton" have any actual cotton in it? Or are manufacturers using "cotton" as a descriptor, kind of like "cotton candy?" Descriptions online are hard to parse. It seems like the stuff is entirely poly, but it's not definite, and a lot of stuff is the usual translated-into-gibberish garble.
Do you have a doctor you can ask for a steer? I know you said the allergy was rare, but there must be some people who have to wear masks for work who have that allergy and who have found workarounds.

Every description of "hot air cotton" I've been able to find characterizes it as "ES ethylene-propylene side-by-side", an extruded synthetic fiber. And if it's in a mask that's heat-sealed together, not glued or sewn, it's more than likely a synthetic.
A quick burn test will tell you if it's a synthetic fiber (melty) or a cellulose fiber (ash like burning paper) but won't distinguish cotton from rayon. And anyway it probably won't be rayon or genuine cotton because of rayon and other cellulose fibers' tendency to absorb a lot of moisture in a clammy, wet way rather than wicking moisture outward to evaporate.

These are the surgical masks I've gotten in the past, with an explanation on the page I linked that it's made from "three layers of what’s called non-woven fabric, which is basically fabric made from plastic."

Moldex N95 masks may not be intended for a medical context (or maybe they are, I don't know), but they _are_ real N95 masks. They have a woven texture but it's more springy and plasticky - it doesn't feel like cotton. I also really like their SmartStrap stuff. (I have these which reduce VOCs also)

"hot air cotton" is synthetic fiber and does not contain natural cotton:
Product Name：ES Hot Air Cotton
Alias: mask cotton, ES fiber cotton, filter cotton
Material: polyester fiber, low melting point fiber
Somehow, "cotton" has come to mean a type of material that does not actually contain any cotton.
I can't imagine any reason for actual cotton to show up in a medical mask. Cotton is hydrophilic and a medical mask with cotton fiber would get soggy and stop filtering pretty quickly.

The filter material in elastomeric masks is safe. I like the 3M and GVS masks, with the added bonus that they don’t create waste.

It also seems like you could get dispensation to wear a mask that contains no cotton, given your allergy; your university's accommodations office should be able to help.
