These are the type of filters we are using in our cloth face masks for my family. The company, Filti manufactures home filters; during this pandemic they changed their main focus to printing face filter material. Read the spec sheet on it to answer many questions.
July 3-6, 2020 they are offering free shipping. The material is manufactured in USA. The company is located in Lenexa, KS but their production line is in another location (still USA). Be sure to check out their youtube tutorials.
I really like this filter material. I put them inside my cloth masks.
They have tutorials on how to make a mask with their kit which is a no sew – which is pre-cut filter, elastic, and a nose bridge. You will also need scotch tape, and a stapler (with staples). I followed the video when a son dropped by that needed a face mask right away for a haircut. I made him 2 in 5 minutes. Not how I would normally do it, but it was good for a pinch.
I have a self healing mask, a rotary cutter and I cut a “template” out of acrylic for the filter. I can cut a couple at a time easily (maybe more depending on how hard you push down when you cut). I was able to cut quite a few in a short time and fill a ziplock so family can pull from the bag and put in their freshly laundered cloth masks.
About the template: I used 1/8" (proofgrade) acrylic because there needs to be room for the wheel on the rotary cutter to press up against the template. I used a pattern by SewCANShe.com that was freely given out for non commercial use.
I scored on the TOP of the template so it wouldn’t give a ‘drag’ to moving the template across the fabric. I included the website I got the template from, the suggested “darts” (I probably should have put a small circle at the top so I could mark the darts.)
The larger circle in one end is like all the other acrylic templates I have made for my masks — it is a circle cut out in approximately the same location on ALL my mask templates so I can hang it on the wall on a nail.
TO SAVE THE TEMPLATE: look for the line drawing below, and using the Chrome browser: right click on the drawing, SAVE IMAGE AS and give it a descriptive name and notice that it will save as an SVG. This means you can send it as is to the Glowforge. Score all the words, and the darts, and cut everything else.
I plan on cutting a rectangle template for masks my mother-in-law made us this weekend. I’ll probably just use my quilting strips the width I need and length and use the one I cut as the " length" as that will make it faster.
