Covid Mask with replaceable filter

After tons of 3D models that are not ideal for this emergency situation, this is my best bet for facial protection. The mask is relatively tight for most people and can be softened at the nose part and cheeks with a hair dryer to make it as snug and comfortable as possible. I have used a vacuum bag that has HEPA and anti allergy filters and it's supposed to filter particles of 0.5 microns. I know this is not ideal, but it's for those that have no alternative and cannot find masks in pharmacies and drug stores. It can be easily washed after a day of wearing using warm water and soap. I also recommend using an alcohol based substance to wipe it after washing. In most countries vacuum bags should be easily found. Simply cut a square piece and it's a tight fit. The mask frame used to hold the filter snug on it it's a bit larger to accommodate for the filter. In my case, it works great with this filter. If it's too tight or too loose, simply scale it by 1% or 0.5% depending how you need it. I will leave this here with a licence to remix, distribute, etc. Although I've tried my best to make a working face mask, I cannot be held liable or accountable for any injury or damage thaty may occur during use. I repeat, treat this as a last resort solution. Print and use at your own risk. All the best !
