Everything about masks

1. How to sew a mask


Requirements: cotton canvas, scissors, sewing machine (needle and thread), string (shoelace, string, possibly even rubber, but beware the possibility of its destruction when boiling), or flexible wire, safety pin.

We cut out a rectangle of minimum size 44 cm x 28 cm from the cotton material (maximum recommended weight 120g / m2, canvas), or increase the base dimension by shrinking the cotton fabric in each direction during forming.

Create the shorter sides of the rectangle 2.5 cm and sew 2 cm from the edge with a straight stitch.


Fold the rectangle in half, stitched edges on top of each other, face up.

Create shorter sides 2 cm and sew in the zigzag stitch on the edge, so that on both sides of the drape there are tunnels to stretch the lace, weave, bow or something similar. It is also possible to sew a 14 cm wire (Meryup-Cycling sro recommends this wire), the edges of which are bent in the shape of an eye to prevent injury. Put a wire into the bottom pocket of the mask and sew about 0.5 cm from the edge with a straight stitch, but only between the zigzag (sinuous) seams so that the tunnels are not stitched.

Now the drape is ready to stretch the lace. Stretch the lace about 130-150 cm long one and the other through the tunnel pin, so that the free ends of the laces remain on the side with the wire, i.e. on the side of the drape without a hole. If the mask is not immediately used, it is good to tie the loose ends of the lace to a loose knot.

2. Inserting Filter into Mask


Fold the A4 paper from one short side by about 1 cm. Put the nanofilter into the folded paper so that it protrudes slightly (about 1 cm) on the long side. Place the whole paper with the nanofilter in a mask. Hold the protruding nanofilter from the outside over the cloth and pull the paper out. The filter is situated in the cloth and is ready for use.

3. Mask maintenance


Remove the used mask while holding only the shoelace and boil the whole including nanofilter for about 15 minutes in boiling water. After drying, remove the filter and discard. After drying, iron the cotton cloth from both sides and insert a new nanofilter for further use.

It is good to change the mask during the day, not to re-use one with a single filter. After each removal, the mask should be placed in a resealable plastic bag until boiling, unless boiling immediately.


ATTENTION! This procedure may not be suitable for all filter types. You need to experiment. If it is not possible to boil the filter together with the mask used, it is necessary to remove the filter, place it in a plastic (microtene) bag and dispose of it before cooking. The mask itself is then produced in the same way, and ultimately ironed from both sides.

4. Instructions for the Correct Fit of the Filter Mask


Prepare the veil with the knot apart so that the seams point upwards. In this way the seams will be oriented towards the face.

  1. Put the veil over your head so that the knot is facing down.

  2. Split the knot.

  3. Use your hand to shape the wire to wrap around your nose.

  4. Pull the veil off with the laces and tie in the back, taking care to remove the laces from the veil.

  5. Shape the area around the nose so that the material is snug. The mask should cover the entire lower part of the face.

5. Instructions for Proper Removal of Mask


The mask should be removed correctly. After untying the knot behind your head, the mask must not fall on your clothes - the possibly contaminated top side should not touch clothes or body. The following procedure must be followed:


  1. Untie the lace behind your head and hold the ends in both hands (in the case of a rubber band or a flexible lace, just pull over the head and hold in both hands).

  2. While holding the laces, move your fingers to the top of the mask and grasp the corners at the top of the mask.

  3. Pull the mask outward to increase the space for stretching over your head

  4. Stretch over your head and remove.

  5. Place the mask in a plastic bag or straight into a cooking vessel.
