You can do a DIY mask fit test for around $7 now. I've tested it out (thanks to @ann_santori for the tip) and this $7 atomizer works, here's how (see thread) amazon.com/gp/product/B08…

1. Make a Sweet N' Low solution or purchase bitter solution. See (10:25) to learn how to make the Sweet N' Low solution (basically just mix a bunch of Sweet N' Low with hot water).

2. First, do this without a mask on. Take a garbage bag and put it over your head and shoulders. Tighten it around your shoulders/etc, but not so tight it totally cuts off your air supply (obviously). But so it forms a little bubble around your head.

3. You should have the garbage bag around your head/shoulders tight but loose enough where you can sneak a single hand into the bag. Sneak a hand in and move the bag around so you've got enough room for your head to move around a bit.

Here's a picture.

In this example, they had someone else doing the test and made a small hole in the bag. For this test, using this $7 atomizer, we won't put a hole in the bag. But pic should give you an idea of what the bag over head should look like.

4. Take the atomizer (filled with your sweet n' low solution or bitter), and sneak it into the bag with one arm. Use your other arm to keep the bag kinda tight around you if you can.

5. Point the atomizer *away* from you and downward. This atomizer makes some droplets (will get things wet) along with aerosols, so yo want to point it down and *away* from your head/face/mask/etc. Like this, at the bottom of the bag:

6. With no mask on, run the atomizer for a few seconds. During these tests you need to have your tongue out - you will be *tasting* the air, not smelling. So stick your tongue out through your lips & breathe through your mouth. How long does it take you to taste the sweetness?

7. If it takes you more than ~10 seconds to taste any sweetness then you may need more sweet 'n low in your solution or this may not be a good test for you (try bitter instead). Say it takes you ~5 seconds to taste the sweetness, that means you'll want to run the atomizer for at

least ~10 seconds during the different test runs. Now take the bag off and wait a bit for the sweet taste to totally leave your mouth & don't eat or drink anything.

8. Put a mask on and put the bag back over your head, sneak atomizer under and run it for a few seconds. Have your tongue out, breathe through your mouth and feel for the taste of sweetness. After ~30 seconds run the atomizer again for a few seconds like you did before. Should do

this for ~1 minute total. Then go through different situations. You just did standing still. Next do a test while talking, same procedure as before, for ~1 minute. Here are the different situations (26:19). Once you get through all of them, you can crack

open your mask a little bit and see if you taste sweetness (you should!). If you taste even a hint of sweetness during any of the tests then this is considered a failure. Standard disclaimer: this is a DIY thing, don't assume you're safe bc you did this, etc.

Amazon list with links: amazon.com/ideas/amzn1.ac…. You can skip the garbage bags if you already have some (don't need to be transparent but it's nice), same for Sweet 'N Low.

The atomizer at the top of this thread is no longer available on Amazon US. See above tweet 👆for an Amazon "list" I will keep updated with a link to the least expensive similar atomizer on the US Amazon store.
