The present invention provides an exemplary respirator which may be worn effectively by individuals with beards or other non-conventional facial features such as deep scars. The respirator preferably comprises a means to either seal or plug the user's nose to prevent the user from breathing air in through their nose and also a main housing further comprising a mouth piece, a filter housing, a saliva collector, means for attaching a strap to the main housing, and a strap to keep the mask positioned properly on the user's face. The filter housing is preferably sized to accommodate a removeable dust cartridge and a removeable fume cartridge.

A dog respirator including a mask adapted to surround the dog's head and a positive pressure air supply and filter separate from the mask and adapted to be placed on the dog's body away from the dog's head. The air supply and filter may be attached to the dog's back using a harness. The respirator/mask surrounding the dog's head is connected to and receives positive-pressure filtered air from the filtered air supply so that the interior of the mask is maintained at positive pressure relative to atmospheric pressure with filtered air.

A dual-purpose muzzle is capable of protecting the canine handler from a bite while providing lifesaving oxygen to a canine in distress. The muzzle is designed to clip behind the head like a soft muzzle while delivering needed oxygen with its internal oxygen tubing and specially designed port for quick hook up. The port allows for any standard EMS tubing to connect to the muzzle. This allows for a continuous flow of oxygen directed to the snout and mouth of the canine allowing the handler to be hands free to address any other emergencies.

There is provided a head wearable air purifier comprising a first speaker assembly and a second speaker assembly, wherein the first speaker assembly comprises a filter assembly, an impeller for creating an airflow through the filter assembly, a motor arranged to drive the impeller and an air outlet downstream from the filter assembly for emitting a filtered airflow from the first speaker assembly. The head wearable air purifier further comprises a nozzle arranged to receive the filtered airflow from the first speaker assembly, the nozzle comprising an air outlet arranged to emit the received filtered airflow from the head wearable air purifier. The impeller is a mixed flow impeller that has a generally conical or frusto-conical shape, and both the impeller and the motor are disposed within an impeller casing that is generally frusto-conical in shape.

The present invention relates to an improved mask apparatus for veterinary applications. The mask may be used for dogs in particular. Most prior art masks are conical. This leads to problems in comfort and effectiveness. The present mask has a cross sectional profile and an opening shaped similar to an animal's muzzle. It has a flat top and a flat bottom, slightly wider than the top, and rounded sides. It also extends backwardly from the top of the opening to the bottom of the opening, so as to comfortably cover the commissure of the animal's lips.
