A personal use air filter includes a water chamber through which the air is initially bubbled to remove particulates, vapors and gases and to humidify and cool the air before it is delivered to the user. In most cases additional filtering is provided downstream of the water bath using an adsorbent filter or an adsorbent filter in combination with a particulates filter. The unit may be power operated using batteries contained within the housing in a sealed battery compartment.
