Fast, No Sew Masks: filti material for resuable masks (Step-by-Step Instructions w/ Photos)

Updated: Aug 26, 2020

This is not medical advice. Step-by-Step instructions with photos at the bottom of the post.

I read that this filti material blocks 84.03% of particles when it was tested -- 1 layer of filti + cotton. This is not the same as a N95 mask -- which blocks 95% of particles, but it is better than nothing and better than just cloth.



For my masks, I have been using reusable foam packaging and paper filters and rotate them within different scarves. They work pretty well, but have not been tested (obviously :) ) what % of particles they block.

It takes a few seconds to make a filter -- and 1-2 minutes to make mask.

-- Step-by-Step instruction with photos at the bottom of the post.

I made 10 filters -- actually 2 layers of filti (more than the 1 that was tested), by gluing 2 pieces together.

** Check out the YouTube video below -- wearegoodatthis1 channel.

In theory, particles of coronavirus can live up to 72 hours or maybe a week at the longest on surfaces.

** If you rotate and use a different one each day, in theory, you don't have to wash them, any coronavirus particles will be dead 1 week later when you use that filter again.

I just use safety pins to secure the filti filter in the scarf and change each day. It's in the video.

Info from WHO:

"The most important thing to know about coronavirus on surfaces is that they can easily be cleaned with common household disinfectants that will kill the virus. Studies have shown that the COVID-19 virus can survive for up to 72 hours on plastic and stainless steel, less than 4 hours on copper and less than 24 hours on cardboard.

As, always clean your hands with an alcohol-based hand rub or wash them with soap and water. Avoid touching your eyes, mouth, or nose."


Stay safe, everyone! Give it a try! We are good at this!


Step-by-Step Instructions:


- Handerkchief, bandana, scarf

- filti filter or other filter

- 2 cloth straps (or something to help you tie the mask around your head)

- 3 safety pins

1.) Make 7-10 filters; I switch them out each day. I numbered all the filters and rotate to the next one in order.

- The reason I switch them out each day is because in theory, any coronavirus particles that may be on it will likely die after 72 hours or 1 week.

- For 1 filter: I cut 2 pieces of filti material and glued them together with a hot glue gun (not shown in photos -- it's in the video.)

** The pieces were big enough to cover my nose and mouth, but small enough to fit within a scarf or handkerchief. (See photos)

** If you do not have filti, you can try a different material as a filter; it's better than just cloth. See this link or check out a reputable website like the CDC or WHO.


2.) Lay out your handerkchief with the part you want showing to the outside facedown as shown in the photo.

3.) Put your filter in the bottom half.

4.) Fold the top half over to form a triangle.

5.) Fold up the bottom corner a little bit and safety pin in place.

6.) Fold in one of the other corners.

8.) Lay 1 strap over it; and safety pin the strap + handkerchief in place.

7.) Repeat on the other side.

Photo on the right shows what it looks like when you tie it around your head. See the photo below.

The next day:

Use the next number filter in your pile and repeat. :)

That's it! Give it a try! We are good at this! Stay safe, everyone! :)
