Abstract

An N95 mask air filter state detection device. The device can be integrated or attached to the N95 mask and includes an electrical sensor coupled to the air filter. The sensor detects static electrical or charge levels of the air filter and provides the electrical level values to a single chip microcomputer. The microcomputer, upon detecting values less than a preconfigured threshold, provides a signal to an LED to illuminate, to a buzzer to play an alert, and/or to a remote paired electronic device. The visual and audible alerts indicate the need to change the filter and thus prevent individuals from using non-functional masks. The alerts also prevent individuals from throwing away functional masks as non-emitting LED and silent buzzer indicate functional filter.
