Care to provide a basic Google source that says N95 Surgical Respirators are made from pulp? Okay, let me provide you another source or two. Here's the 3M 186

  It seems to be the fibre, but I'm not enough acquainted with materials to know where or what. The wording seems to be that is literally used in surgical masks: https://www.vancouverislandfreedaily.com/business/nanaimos-harmac-mill-works-to-fill-doubled-pulp-order-for-medical-masks-and-gowns/ https://www.vancouverislandfreedaily.com/business/nanaimos-h... > K10S pulp is made from western red cedar that produces a soft fibre that makes it suitable for the final products made from it. “It’s been tweaked over the years to come up with the right formula that allows it to go into the medical supplies,” Sampson said. Your source indeed says: these materials are used. But it never says they are listing all the materials that are used. It could be that they mention it because those materials can touch the skin. I don't see anything that mentions the filtering technique/materials inside of those masks. I also don't see how the materials are tweaked. So I don't think it's as easy to read the brochure and believe that they mention everything on it. I guess the Polypropylene fibrids in the filter contains the K10S ( = the pulp ) An indication to support this can be found here: http://www.freepatentsonline.com/8172035.html http://www.freepatentsonline.com/8172035.html ( Search for K10S in the text and read the entire surrounding text) As stated before, I'm not an expert.

    K10S pulp is definitely used in surgical masks. This is a fact and I admit it. So far I've shown that K10S is not used in N95 respirators which is the original statement. I've shown evidence in good faith and you have not. None of your links makes reference to N95 Respirators. Please provide a direct reference that K10S pulp is used in N95 Respirators.

      Not everything is black or white... What you said now is not what you said before. You literally claimed it was just the bag, lol: > I'm no expert, but I am sure the only pulp used in a N95 respirator is the box they put the 10 or 20 masks in. They can easily replace that with a bag. And I repeat: > “It’s been tweaked over the years to come up with the right formula that allows it to go into the medical supplies,” Sampson said Not every company is going to put their "secret sauce" online. Just send an email to 3M to ask the question instead of trying to guess it. https://www.3m.com/3M/en_US/novec-us/support/contact-us/ https://www.3m.com/3M/en_US/novec-us/support/contact-us/ Google can't solve everything. As an alternative, you could ask it on StackExchange. Then Google can pick it up for you and you can have your nice link :p And also, you are looking for "surgical masks N95 K10S" in Google. I googled the root question and that is: where is K10S used in Polypropylene , but you don't seem to grasp/accept it. I already explained why it would be better to look that up...

        This may be the pulp connection to the Polyurethane filter. Filtering face-piece respirator having a face seal comprising a water-vapor-breathable layer Patent Assignee 3M INNOVATIVE PROPERTIES COMPANY (St. Paul, MN, US) http://www.freepatentsonline.com/9408424.html http://www.freepatentsonline.com/9408424.html In discussing a way to take water vapour from exhaled breath away from the filter surface. If this is the case while the polyurethane is the primary material the pulp fibre is applied to it as a layer which may not appear in a spec sheet. "In some embodiments, a face seal may consist only of a water-vapor-breathable layer and a wicking layer (that is located on the rearward side of at least a portion of the water-vapor-breathable layer), with no other layers being present. In other embodiments, other layers may be present in the face seal. There are several general approaches to providing such a wicking layer, which approaches will be described herein in a non-limiting manner. In one approach, a fibrous wicking layer (e.g., a non-woven web, a woven or knitted fabric, and so on) can be comprised (e.g., generally, substantially, or completely) of fibers with “moderate” hydrophilicity. Materials that might be suitable for such fibers include e.g. certain nylons, polyesters, cellulose acetates, and so on. In another approach, a fibrous wicking layer can be comprised of relatively hydrophobic fibers (e.g., polyethylene, polypropylene, natural rubber, and so on), but with the web incorporating some portion of relatively hydrophilic fibers (e.g., cellulosic fibers, acrylic fibers comprising a significant amount of hydrophilic co-monomer, and so on). That is, any suitable blend of hydrophobic fibers and hydrophilic fibers can be used to arrive at the optimum balance of properties. In a variation of such approaches, a fibrous wicking layer can be comprised of relatively hydrophobic fibers but may further comprise hydrophilic particles of any suitable composition (e.g. hydrocolloids, WOOD PULP, starch particles, and so on). Conversely, a fibrous wicking layer can be comprised of relatively hydrophilic fibers but may further comprise hydrophobic particles of any suitable composition."
