Filter mask tutorial

Either because in his day there was a shortage of surgical masks and many people chose to make their homemade mask to protect themselves, or because people seek custom masks with a special design and choose to make them at home, the point is that many look for a filter mask tutorial to make their own masks at home. 

The first thing to know is that fabric and / or homemade masks, as they are not approved and do not have an adequate filter, are not the most recommended, even if we follow the filter mask tutorial to the letter. They were an option given the scarcity, but today where it is already possible to obtain surgical masks anywhere, some of them customizable masks or brand masks like those of Béjar Masks, it is no longer necessary to make them at home. Even so, in case you find yourself in a hurry, we give you the filter mask tutorial.

Filter mask tutorial: steps to make your homemade mask

The homemade filter mask is made up of two layers of fabric and a pocket between them to put an optional filter. It is fastened with a string or elastic ties in the ears. You can also sew a string to fit around the head. 

You can choose any cotton or cotton and polyester fabric that you like. You can also use the same fabric for the outside and lining if you want, or use different ones to help you remember which side is inside and which is outside. If you want to ensure the size and shape of your mask, download patterns from the internet to cut your piece of fabric exactly. 

To protect the sides of fabrics, give them a clean finish by adding a zig zag stitch, or if you have a serger (a specialized type of sewing machine that makes stitches), use it. This should only be done on the sides of the main piece of fabric.

- Fold your main piece of fabric in half with the right sides together.

- Pin the top zigzag edges.

- Sew on both sides of the top zigzag edge with a seam allowance, leaving a space in the center. This space will be the opening for the filter pocket.

- Center the seam allowance and use an iron to iron the seam allowance.

- Turn the mask to the right side.

- Add stitching to both sides of the seam. It should be approximately 1/8 "from the seam and keep the seam allowance flat and in place.

- Flatten the mask and position the seam / pocket opening down from the top edge. To help in the next step, you can press this flat part and pin the open edges together.

- Sew an edge stitch around the entire outer edge as close to the edge as possible.

- For these masks use a wire.

- Start with a piece of wire and use pliers to twist the edges a couple of times and round them so they are not sharp. Punch a hole through the fabric once you're done.

- Insert the wire through the pocket opening and center it on the top edge of the seam.

- To lock it in place, sew it just over the previous stitch at the top edge of the pocket opening seam. Your pocket should still be open and functional.

- Working from the front of the mask (the back is the side with the pocket opening) add three folds. You can add as many as you want, but this is more convenient.

- Pin the pleats and iron them.

- Sew along the entire side with an edge stitch to keep the pleats in place and repeat for both sides.

- Center a strip on the back of one of the folded sides with the right sides together and pin them in place.

- Fold the excess towards the front of the mask and fix it with pins.

- Sew the bias to the mask with an edge stitch.

- Repeat these steps for the opposite side.

- Fold the bias tape and press the folds down with an iron.

- Repeat (strip of fabric cut on the bias) for both sides.

- To finish the edges, fold the bias towards the mask twice and fix it in place. You should have the edges folded. This junction will create a tunnel through which the string will slide.

- Sew along the inside edge of the trim with an edge stitch to hold the trim in place and allow room for the twine. Repeat for both sides.

- Take a string or elastic strap and attach one end to a safety pin.

- Slide the safety pin through the side and push it all the way.

- To secure the string, double knot the ends so they are tight.

- To finish, pull the string to slide the knot into the trim. This will hide the knot. This part can be a bit tricky depending on the size of the string you use.
