Get a 2 liter bottle and have scissor and box cutter.
ofc duct tape too.
when making filter, use salt because it has been proven that the COVID19 cannot survive on salt, so make a filter with salt and don't use the fine salt (you don't want to breath in salt)
When making filter, use empty soda cans or empty redbull cans (the bigger the better, so you can breath air better) and it should look like this. (this part has to be the hardest and annoying one to make)
Cover it with a cloth that you don't use, if you can't find any cloth that you don't use, choose the least favorite (yes it's worth it)
Make a sandwich like this.
use either a nail or a screwdriver to punch hole to a cover.
Mark where you are going to make holes, use drill to make holes or do it with a sharp knife (be careful)
P.S. it is a plastic so you can't make a hole if it is a glass.
After you make holes on the buttom, clean it with a tough cloth to remove the small plastic trash.
make a hole to your 2 liter gasmask, side left or right and ofc front if you want (make only one hole) and tape it so it doesn't leak air to the sides.
Again make a sandwich.
use duct tape to keep the salt inside the filter
Finished filter should look like this.
the filter "entrance" should look like this, cover it well with duct tape and don't let any sides air in, only thru the "entrance"
P.S. It is 3 am when I made this so my english isn't tip top, I started to make this because serveral people was infected in Greenland.
It should look like this, it may look thin but plastic can strect so don't worry about that.
only problem with this that I don't know how to make exit valve so CO2 can exit better rather than pushing it out where fresh air come in.
ofc remember to make any rope/tape/belt to make a strap so you can having it on without using your hands.
1. I have no idea if it helps or prevent catching the COVID19 but it is a lot better than nothing, the salt filter will (maybe) kill the virus and only clean air goes in.
2. Air droplets (contained with Coronavirus)
should prevent it to get into your eyes if you have the mask on, again not 100% sure but it won't gets onto your face ar least.
3. Wash your ******* hands.
Also thank you for looking at my makeshift gasmask.
Critize it how I can improve and how I can make a exit valve.
