ABSTRACT:
A thin profile PAPR filter blower system and method of use that operates in conjunction with a thin profile filter cartridge. The design allows an unaided user to swap filter cartridges without compromising the safety of the user, even when the user is located in a contaminated environment. Other components of the system include a blower control mechanism, a short conduit for delivering filtered air to a worn face mask, a self-contained power supply, optional attachment features to secure the system to a wearer's body, features for sealably connecting and replacing filter cartridges, and a quick change locking mechanism to secure and release filter cartridges. An optional remotely located control device is also provided.
