A face mask containing a network of conductive activated carbon meso-fibers crosslinked with a crosslinking agent bonded to a insulative polymeric micro-fiber based purification element. The purification element is captured between two ridged porous elements and contacted to the face by a biocompatible flexible polymeric seal. Optionally the front cover attaches to a main frame of the mask through a system of sliding locks that are coupled with bayonet latch mechanisms. The face mask attaches to the head of a wearer through a harness that couples with the sliding locks or alternatively with a biocompatible adhesive.

A modular antiviral air filter assembly for filtering displaced air in a toilet has a ventilated filter housing having a bottom sealing surface, a peripheral side wall, and a top lid, the filter housing fixed to or formed contiguously to the underside of the top lid of the toilet, at least one antiviral filter disposed within the filter housing having contact with the displaced air from the bowl of the waste collection utility. The antiviral filter assembly closes and seals against the donut rim seat after use and remains sealed during flush operation of the waste collection utility wherein the displaced air from water filling the collection bowl is filtered through the one or more antiviral filters before egress out of the ventilated portion or portions of the filter housing.

A face mask for filtering air includes a face seal for providing an airtight flexible seal around the nose and mouth of a user, a support sealably attached to the face seal, wherein the support has an open area that allows for passage of incoming air and outlet valves for expelling exhaled air, a front shell for removably attaching to the support, wherein the front shell has inlet holes for allowing the incoming air to pass through the open area of the support, and a filter for filtering particulate elements from air. The filter is configured to be housed between the front shell and the support. The face seal provides a direct connection between the filter and the user.

The present invention generally relates to an x-ray source and specifically to an x-ray source suitable for large area x-ray generation. The invention also relates to a system comprising such an x-ray source.
