	*The formal name is "CAPR" or Controlled-Air Purifying Respirator
	*A Device Mainly Used as a filtered/safe air supply in enviroments where there IS oxygen, and the user can breath normally (as in lung function isn't impaired), but a chemical/biological/particulate hazard exists/is expected
	*Is essentially a forced air filter, with a hose leading to a mask
	*Typically is a belt with the power/controls/filter, then a tube to a mask/hood
	*A Similar "box" can feed a [[Positive Pressure Personnel Suit]] , a type of hazmat suit for bio uses (ie doesn't protect against heat (like firefighting "bunker suits" , or from certain liquids and/or radiation like other Hazmat suits
	*Many DIY devices are essentially adapted [[CPAP]] machines

	*Hood and hose are discarded after each use - [https://www.massgeneral.org/assets/MGH/pdf/disaster-medicine/2019-Novel-Coronavirus-(2019-nCoV)-Toolkit-version-1.29.2020.pdf]

	*Used in [[Biosaftey Levels]] 3 and 4 (Medical, Bioscience, etc)
	*Also useful for welding with large amounts of flux in non well ventilated spaces etc

	*All these go for ~1000-3000 USD (Welding Helmet part makes up the most, but still is most likely overpriced
	*They typically include the welding eye protection, the air system, a hardhat, a hood, and a system of all these being integrated, and "slidable"?

	~~=Basic Design=~~
	~~==Container==~~
	*Either a backpack, like in the video, or a 3d printed "shell"

	~~==Power Supply==~~
	*The associated electronics
	*Preferabbly something swappable / [[Hot Swappable]] either (For Emergency need (ie we need something that "just works" NOW this may be a lesser need, even just throw a 9/12v battery in the backpack etc)
	**A OTS System such as RYOBI 18V etc
	**OSE System with the batteries in a 3d Printed shell with inserted metal contacts

	~~==Controlls==~~
	*Should be simple enough to use an arduino
	*Indicators of flow and status MAY be needed to reach proper capability (if it fails you NEED to know if in a "Hot Zone")

	~~==Blower Fan==~~
	*Something with '''X M^3/H ''' airflow (without filter) and '''Y M^3/H ''' airflow (with filter)
	*Either OTS or a 3d printed fan with ots motor, or fully open source

	~~==Filter Mount==~~
	*A Standard mount, and 3d Printed adapters for different cartriges

	~~==Filter==~~
	*Some sort of standard cartrige
	*Contractor grade face mask cartriges should work for welding
	*Due to the "END IS NEAR" supplies and the surplus military supplies, CBRN grade CAN be used, but is overkill and thus more expensive than need be in most applications
	*Standard Biosaftey cartrige?

	~~==Hose Adapter==~~
	*Standard?

	~~==Face Mask==~~
	*Standard CPAP?
