How to make face masks for oven filters

One of the most effective materials you can use to prevent the transmission of coronavirus 2019 may be the lining used in furnace filters designed to clean air. Making one should not take long, provided you have some basic sewing supplies.

Remember that these materials are valuable – people who confront the disease need such defenses right away, so don't buy out your hardware store and hoard a bunch of filters. Limit home use of these masks to cover when you or a family member is experiencing symptoms.

If you have the time, resources and some sewing knowledge, you may even consider making and donating these masks to healthcare professionals on the front lines to confront COVID-1


Safety Instructions: The US Centers for Disease Control recommends officially certified N95 masks for protection. Everything but official equipment has no guarantees of safety or efficiency.

Step 1 – Find a filter

Check the marking if you can. Some oven filters are specifically designed to stop viruses. No matter what type you have available, use a new, clean filter if possible. Using a used, dirty sheet can be dangerous.

Step 2 – Determine the pages

If there is an arrow on one side of the material, it is the side to mark as "Inside."

Step 3 – Remove Cardboard and Thread

These heavier elements get in your way and can cause discomfort or damage.

Step 4 – Measure and cut

Divide the material into seven inch squares.

Step 5 – Add Structure

Sew a robust pipe cleaner or swivel band along the top edge.

Step 6 – Fold pages

Scrape the sides down to four inches and place them in place so the center is seven and the sides are four.

Step 7 – Add Elastic

Cut two six inch pieces of elastic and sew two edges of the filter closed around them to create ear loops.
