Question 1

How do you take off the face shield after use? Let's say that you just went to the market and are about to get into the car. Do you wipe the visor down with alcohol first before taking it off?


This is what I do, not necessarily the best practice:

  • When I go shopping I wear the face shield and also reusable rubber gloves.
  • When I get back in the car, I wipe the front of the face shield off with a wet baby wipe soaked with hand sanitizer.
  • Next I take the face shield off and put it on the passenger seat, front down.
  • Next I wipe the back of the face shield with the same wet wipe.
  • Next I add more some hand sanitizer to the wet wipe.
  • Next I sanitize the gloves and anything I touched with the gloves (e.g. car keys) with the same wet wipe.
  • Next, I take the gloves off and put them on the passenger seat beside the face shield.


Unless you wear full PPE including the full body gown, the N-95 mask, the face shield and the gloves, you may become exposed to Coronavirus whenever you enter the environment in which Coronavirus is present in the air (aerosolized) or on the surfaces. However, the face shield alone should help reduce the Infectious Dose (the amount of virus exposure at the start of infection), by providing a physical barrier to water droplets containing Coronavirus and by making it much harder to touch your face while you are wearing it. Reducing the Infectious Dose should at least make your symptoms milder in case you become infected with the Coronavirus.


Question 2

Can wearing a face mask of any kind reduce your chances of getting infected?


So far the authorities in the western countries have generally been advising against wearing masks when it comes to general public. Sometimes the risk of getting infected when removing the mask and the risk of touching your face when wearing the mask (to adjust the mask) were cited as rationales for this recommendation. Many suspected that the main reason was that there was, and is, a shortage of masks for the health care workers, who need the masks much more than general public.

Just within the last few days, the recommendations seem to have started change. Some of the reasons cited for this is the experience from countries like China, South Korea, Taiwan and Japan, which have successfully "flattened the curve" and where a lot more people wear masks than in the western countries. While correlation does not necessarily imply causations, there seems to be mounting evidence that wearing masks reduces the chances of infection.

There are several potential issues with wearing a face mask mask that have been quoted in the media:

  • If the general public is told to wear face masks, the demand for the surgical masks and the N-95 masks will skyrocket, making it more difficult for the frontline health care workers, for whom they are essential, to get them.
    This is an absolutely valid argument! Unless the hospitals in your area, and in your country as a whole, have enough medical face masks, then please do not try to obtain some yourself, at least not until the supply of the masks has exceeded the demand from the health care institutions. Instead, you may want to make your own DIY face masks, as it has been advised by CDC in their Strategies for Optimizing the Supply of Facemasks.
  • Wearing a face mask will make you more likely to touch your face in order to adjust the mask.
    This is where wearing the Face Shield on top of the face mask comes in handy!
  • Unless the face mask is worn properly and it is N-95 rated, wearing it will do more to protect those around you in case you are infected, then to protect you if someone around you is infected.
    This is absolutely true! However, if the majority of people wore the face masks in public (like in Taiwan and South Korea), and even better if they wore the face shields and the face masks, we would all be better protected and the spread of the Coronavirus would be slowed.
  • Taking the mask off, if done improperly, can actually infect you with the Coronavirus.
    This is also true! However, there are numerous resources on thee Internet that will teach you how to do that. For example, How to Put on and Remove a Face Mask published by the San Francisco Department of Public Health.
  • If people wear face masks that will give them a false sense of security, so they will be more likely to go out and ignore the guidelines for physical distancing, and will thus increase the spread of the Coronavirus.
    This is a dubious argument at best. Yes, some not-so-bright and/or careless people will do just that, but I think that they make a small minority of the general public (and if I'm wrong, then we are doomed anyway). However, if the vast majority of people use the face masks (and face shields) as an added protection against spreading the Coronavirus, while still observing all other guidelines, then the damage done by the few Covidiots will be greatly outweighed by the benefit earned by the rest of us.
    A little off topic, the "false sense of security" argument also reminds me of the old argument against putting the airbags in cars, that driving a car with an an airbag will make people drive more recklessly than they would otherwise, thus increasing the total number of accidents and the number of fatalities. A former colleague of mine used to say that, by the same logic, instead of the airbags, the car manufacturers should be installing 9 inch spikes on the steering wheels, pointing straight at the driver's head. Now that would make everyone slow down and pay attention!


Question 3

If I can't find a medical face mask, what other options do I have?


The best answers to this question can be found on the CDC Web page Strategies for Optimizing the Supply of Facemasks. Below is an excerpt (HCP means Health Care Personnel):

  • Use a face shield that covers the entire front (that extends to the chin or below) and sides of the face with no facemask.
  • HCP use of homemade masks: In settings where facemasks are not available, HCP might use homemade masks (e.g., bandana, scarf) for care of patients with COVID-19 as a last resort. However, homemade masks are not considered PPE, since their capability to protect HCP is unknown. Caution should be exercised when considering this option. Homemade masks should ideally be used in combination with a face shield that covers the entire front (that extends to the chin or below) and sides of the face.


Question 4

Question on the Face Shield design: Would it work well if there is a big open space (gap) under the Face Shield?


The most important part of the face shield is the top part (say the top 6 inches or 15 cm), which covers the eyes, the nose and the mouth. However, the longer the shield and the more it wraps around your head, the better. If the transparent plastic is too small or to short, one way to extend the face shield is to glue or tape or staple another piece of plastic to the bottom of it or to the sides of it. The bottom or side pieces don't even have have to be transparent.


Question 5

Why aren't health authorities advising general public to wear face shields?


This is a very good question. One answer would be ask the health authorities, only they should know. One possible reason is that, while it is somewhat normal for general public to wear face masks (especially in many Asian countries) it is not usual to wear face shields. Another reason could be that the there are still not enough face shields for the health care professionals, let alone general public.

This news article (thanks to one Julia for the link) talks about how wearing face shields in public could help fight the Pandemic Iowa doctors: Face shields are an achievable way to provide protections that COVID-19 demands. The Iowa doctors article says basically the same thing that we have been trying to promote. The only thing they have missed is that the general public could be equipped with DIY face shields in a very short order. Otherwise, it will take a very long time to wait for production to catch up to the demand.

Here's an interesting story from Thailand on face shields for babies!


Question 6

What are the pros and cons of wearing the face shield versus a face mask?


According to the scientific paper Face shields for infection control: A review by Raymond J. Roberge, the Advantages and disadvantages of face shields compared with other forms of face/eye protection (i.e., protective facemasks [filtering facepiece respirators, medical/surgical masks], goggles, safety glasses) are:


  • more comfortable
  • protect a larger portion of the face
  • less retained dermal facial heat
  • less fogging than goggles
  • less claustrophobic
  • no impact on breathing resistance
  • no fit testing required
  • can be disinfected easily
  • wearers do not need to be clean shaven
  • easy to don and doff
  • relatively inexpensive
  • no impact on vocalization
  • can be worn concurrent to other face/eye PPE
  • do not impede facial nonverbal communication
  • reduced patient anxiety
  • protects against self-inoculation over a wider facial area
  • may extend the useful life of a protective facemask when used concurrently


  • glare
  • fogging
  • optically imperfect
  • some models may not fit properly over some respirators (e.g., duckbill filtering face piece respirators)
  • bulkier than goggles and safety glasses
  • peripheral fit poorer than protective facemasks

Again and again, a couple of important advantages of the face shields are missed:

  • the DIY version is generally as effective as the "professional" version. The same cannot be said the the DIY face masks.
  • If the use of DIY face shields was promoted by the health authorities, a large portion of general public could be equipped with DIY face shields in a matter of days. Why this is not done remains a mystery.


Question 7

One problem we encountered was fog. Do you have some kind of solution for this?


One of our YouTube viewers (Mary Ann) came up with an elegant solution, by adding weather strip pieces spaced along the strip base to create air flow channel, as shown in the picture on the left below. This method will work well if you are using thin foam (weather stripping), say 1/4 to 3/8 inch thick (6 to 10 mm).


Another, even easier way would be to cut the foam into four 2 inch long pieces and space them 1/2 inches apart, as shown in the picture on the right. This assumes that you are using the foam that is 1/2 inch (13 mm) thick or more.

This way the warm breath air can pass out the top of the mask. This should work for both cold weather to avoid fogging up and for warm weather to provide some cooling air flow under the face shield.

Why DIY COVID-19 Face Shield?

You must have seen photos and videos of doctors and nurses dealing with COVID-19 patients wearing transparent face shields over their N-95 face masks. However, at least here in Canada, there are not enough face shields available even for the front line health care providers, let alone the general public.

But don't worry, you can make your own DIY COVID-19 Face Shield yourself, quickly, easily and cheaply, and we will show you how to do that. All you will need is a piece of transparent plastic, a little piece of foam or weather stripping, an elastic head band, an office stapler and some Velcro if you want to make it adjustable. If you have all the materials, it shouldn't take you more than 10 minutes to make one.

You can also consider wearing your DIY COVID-19 Face Shield it the fashion and social statement in support of the front line doctors and nurses, some of them still working without all necessary PPE (Personal Protection Equipment)!

News (March 30, 2020):

Bauer (, the maker of hockey gear, has announced that it is shifting production to make visors for medical staff, first responders, and those in need. Their main challenge now is that the order demand is currently vastly exceeding their available capacity. Just the province of Quebec has placed an order for 300,000!

We have a few comments about this:

  1. We were ahead of the curve in realizing that millions of face shields will be needed to combat COVID-19.

  2. The companies that are switching to manufacturing medical face shields will not be able to fill even a fraction of the demand. Therefore, our DIY approach is the only way to deploy sufficient number of face shields to not just medical staff, but the population at large.

  3. The face shields made by Bauer look very much like a professional version of our DIY models, which aren't perfect, but are be good enough for now.

How does the DIY COVID-19 Face Shield Work?

Wearing the Face Shield does not relieve you from observing all other precautions recommended by WHO and mandated by your local authorities, such as self-isolation and physical distancing.

The Face Shield should, however, provide an additional layer of protection to you and those around you from airborne droplets that may carry the Coronavirus. It does that by providing a physical barrier that the droplets cannot cross.

Also, wearing the Face Shield will generally prevent you from touching your face, which is equally important in protecting you from contracting this nasty Coronavirus.

The DIY COVID-19 Face Shield is comfortable to wear, and you can easily wear it over your glasses and/or over a face mask. You should wear it when you go shopping for groceries and it whenever you go out of your home for whatever reason.

The DIY COVID-19 Face Shield is reusable, however, you should disinfect it after every use with rubbing alcohol or soap and water. A number of reputable sources (for example this article on, claim that using a 60% by volume alcohol solution is a recommended minimum concentration that will kill the Coronavirus.

It seems that very high concentrations (90%+) are less effective disinfectants than lower concentrations. For example the Alcohol Sanitizer paper by Nina A. Gold and Usha Avva claims that:

The antimicrobial activity of alcohols can be attributed to their ability to denature and coagulate proteins. The microorganism’s cells are then lysed, and their cellular metabolism is disrupted. Alcohol solutions containing 60% to 95% alcohol are most effective.

Our second video showed using rubbing alcohol and a 100 proof Vodka (50% alcohol) as a sanitizer. We have since removed that clip. Rubbing alcohol can be used, unless its concentration is greater than 95%, in which case it should be diluted with water before use. However, if you are low on rubbing alcohol, you can use it to "spike" the vodka you may have laying around and turn it into 60% alc. sanitizer. Just make sure you do the math right and mark the bottle of spiked Vodka "sanitizer - do not drink"!

Although you should sanitize your COVID-19 Face Shield after each trip to the supermarket, or any other store, it is still much more important that you wash your hands as soon as you come home. You are much more likely to have large numbers of viruses on your hands from touching dirty surfaces, than to have them on the outside of your Face Shield. That is why everyone is telling you to wash your hands regularly, while as far as we know, nobody is urging people to wash their faces.

Do not share your DIY COVID-19 Face Shield with others. Instead, show them how to make their own!

Finally a disclaimer: DIY COVID-19 Face Shield alone will NOT prevent you from getting infected, or from passing the infection to others. However, if used properly, it should help reduce the chances of infection and help FLATTEN THE CURVE!

Step-by-Step Instructions for DIY COVID-19 Face Shield

Below are detailed instructions ant tips on how to make your simple DIY COVID-19 Face Shield, similar to the one we made in the YouTube video below.

A) Materials Required

You will need these four things to build your DIY COVID-19 Face Shield:

  1. A piece of transparent plastic (find it on
        (even better, buy from CFS PRODUCTS Inc.)
  2. A piece of elastic (find it on
  3. A piece of foam (find it on
  4. Something to tie the Elastic to the Plastic

A.1) A Piece of Transparent Plastic (find it on
        (even better, buy from CFS PRODUCTS Inc.)

The easiest to use are the binding covers or the presentation covers, which can be obtained in office supplies stores. We are using Staples Presentation Covers. Box of 100 sells for CAD 77.00 at Staples, which is outrageous, when one can order from CFS Products for much much less! Also, check out their YouTube Video!

The presentation covers are just about the right size for a Face Shield. They are a little larger than the standard Letter size paper (8.5x11"). A4 size also works well.

The presentation covers we used is 0.0065" (0.16 mm) thick. If you can find thicker covers, they should be more durable. Just make sure that they are transparent enough.

Some of the presentation covers that are sold are semi-opaque, even though it says on the box that they are transparent.

If you cannot find the presentation covers, or you don't want to spend money buying them, the good news is that nowadays everything is wrapped in plastic and you may be able to find pieces of transparent plastic that are big enough to act as a face shield.

Below are just two examples:

  • Spinach tub lid

  • Hallmark greeting cards box lid


You will only have to cut the edges, trim it to right size and peal off the labels, which can sometimes be tricky. The trick is to do it slowly.

A.2) A Piece of Elastic (find it on

You will need approximately 13" (33 cm) long piece of 3/4" or 1" (20 to 25 mm) wide general purpose elastic, like the ones shown in the photo, to make a comfortable head band.

We bough ours at Walmart. You can also buy them at arts and crafts stores and sewing supplies stores.

If you cannot find the elastic in stores, or to save money, you may be able reuse a piece of elastic from an old pair of underwear.

Even a couple of rubber bands could work, although a nice wide piece of elastic makes wearing the Face Shield much more comfortable.



A.3) Piece of Foam (find it on

The quickest way to build a DIY COVID-19 Face Shield is using a self adhesive foam window seal (weather stripping). For best results use minimum 3/4" (19 mm) wide by 1/2" (13 mm) thick foam.

This should be available at all hardware stores. We bought ours at the Home Depot.

You can also use thinner weather stripping, but in that case you should use two layers.

In case you don't have the weather stripping, you can use any other type of foam, like a strip of packaging foam (shown in the picture below) or a piece of Styrofoam, which you can easily cut to the right size using a sharp Exacto knife.

If the piece of foam you are using doesn't have the adhesive back, you will have to use some kind of glue to glue it to the plastic piece. We found that the regular hot-melt glue gun works the best. Use the low temperature setting, as the high temperature may damage the foam.

A.4) Something to tie the Elastic to the Plastic

You can attach the elastic to the plastic in a couple of ways. Our first idea was to use heavy duty self-adhesive Velcro (which we bought at the Canadian Tire). We found that it sticks very well to both the clear plastic sheet and to the elastic. The width of the Velcro should match the width of the elastic, i.e., 3/4" or 1" (20 to 25 mm) wide. (find it on

Velcro can have a dual purpose, to attach the elastic to the plastic sheet and to make the length of the head band adjustable.

We also tried various sticky tapes (like Duct Tape), however, they didn't stick to well to the elastic and they tend to tear after a while, so stay away from those.

After a lot of trial and error, we found that the best results in connecting the elastic to the plastic sheet were achieved using an office stapler.

Any old stapler, like the ones shown in the picture, will be adequate.







B) Step-by-Step Instructions

  1. Cut all parts to size
  2. Attach one side of the elastic to the plastic sheet
  3. Glue the foam to the plastic sheet
  4. Attach the other side of the elastic to the plastic sheet
  5. You are done!

B.1) Cut all parts to size

Cut all material to the following sizes:

Transparent plastic: approximately 11 inches wide x 8.5 inches high (28 x 21 cm). A little smaller should still be OK. If you are using a report cover, you don't need to do any cutting as it is already the correct size.

Elastic: 13 inches long.

Foam: 10 inches (25 cm) long, or about 1 inch (2.5 cm) shorter than the width of the plastic sheet.

B.2) Attach one side of the elastic to the plastic sheet

Attach the elastic to the top corner of the transparent plastic sheet. The elastic will wend up on the front side of the plastic sheet. The easiest and sturdiest method is to staple the elastic to the plastic sheet.

B.3) Glue the foam to the plastic sheet

If you are using the self adhesive foam, simply line up the foam with the top of the plastic sheet, stretch it a bit and press it down onto the sheet. Make sure that the foam doesn't stick above the sheet.

It is best to attach the foam a few millimeters below the top of the sheet. This is important so that the adhesive on the back of the foam does not stick above the plastic sheet.

If you are using regular packaging foam or Styrofoam, you should glue it using a glue gun. Because these foams aren't as flexible as the weather stripping, you should bend the foam piece before gluing it to the plastic.


Detailed instructions on how to build your own DIY COVID-19 Face Shield will include photos, measures, specifications and tips & tricks.

B.4) Attach the other side of the elastic to the plastic sheet

The final step is to staple the other side of the elastic to the opposite top corner of the plastic sheet. It is best to do this from the outside. If needed you may temporarily peel back the end of the foam, so that you don't staple through the foam.

B.5) You are done!

Your DIY COVID-19 Face Shield is completed and it is ready to be used!
