Ok, One of the things I've been working on are mask coverings. There are 2 options
1- N95 cover 2 -PM2.5 cover They are sewn slightly differently. The N95 has more of a point to it. These are covers for the filters. I can get the N95 masks as shown at $5 each and the PM2.5 @$1 each They are nit included unless you want them. You may be able to buy in bulk at a better price, I'm adding nothing to the cost. The coverings are $10 each and will be made to order. Your options are the Hounds tooth in Black and white Black and blue Black and yellow Black and red May do some black and green if there is demand Also I have the plaids as shown. May be limited on some quantities of different colors 1st version is the PM2.5 shown in red houndstooth Just let me know which version you want and the color.

Are you sewing in a piece of wire over the nose bridge so you can form it for a tight fit?

Are you sewing in a piece of wire over the nose bridge so you can form it for a tight fit? Waste of time. Cooties are very small. Coronavirus is 60-140 nano meter particle size. They will still spew in and out between the pores of the N95 filter and fabric. N95 mask material is a government efficiency rating that means the mask blocks about 95 percent of particles that are 0.3 microns in size or larger. Notice that isn't 100% blockage even under ideal conditions of use. 0.3 microns = 300 nano meters. Therefore Corona virus is 1/2 the size of what a N95 filter is able to filter. 0.3 micrometer of filtration assumes you have a PERFECT seal around the entire perimeter of the mask which isn't possible. Of course, if you have a beard, or stubble, be sure to shave that too. Otherwise what little mask seal you have is further compromised. |

Of course, if you have a beard, or stubble, be sure to shave that too. Otherwise what little mask seal you have is further compromised. All good points, but some miss the point. Many pathogens, such as SARS CoV-2, are primarily spread in aerosolized droplets, which are much larger than the pathogen itself. A mask will provide some protection against those. I can get out of my car and walk through a standard sized residential doorway, but I can't drive my car through the doorway. A good fit is important to improve efficacy of a mask. Facial hair will affect the fit, as will the profile of the nose and face. I am required to be fit tested on a regular basis for an N95 before I can see my patients in the hospital, but even without that level of testing you can get an acceptable fit if you get a good seal. A moldable nose clip is important to help get the best fit possible. I think we also all know by now that a mask will also help prevent an infected person from spreading aerosolized pathogens, which perhaps is their most important function. Moldable nose clip or not, a mask and many other types of facial covering can be helpful to keep us all as safe as possible. Nothing protects 100%, or perhaps even 95%, but anything we can do to help keep us all safer is a step in the right direction. My thanks to Mark and others for coming up with creative ways to make facial coverings. |
