Abstract: Disclosed is a nasal mask assembly. An example mask assembly includes a first part, a filter, a second part, and at least two straps attached to the second part. The first part includes a base configured to engage the face surface around a nose of a user and a filter support extending from the base and defining a breathing chamber. The filter support includes a first outlet and at least one first inlet. The filter is placed over the filter support and covers the first inlet. The second part can be configured to engage the base and a portion of the filter support around the first outlet and to cover a combination of the filter support and the filter. The second part includes a second outlet and a second inlet configured to be positioned against the first outlet.

Abstract: Disclosed is the filter assembly for providing purified air to an enclosed space. The filter assembly including enclosed filter housing for regulating the flow of the air having an inlet port to receive the air, an outlet port for releasing the purified air to the enclosed space, and a hollow chamber within the inlet port and the outlet port. The filter assembly includes a high efficiency particulate air filter unit replacably inserted in the hollow chamber to purify the air. The high efficiency particulate air filter unit includes a first high efficiency particulate air filter, a second high efficiency particulate air filter attached to the first high efficiency particulate air filter, a third high efficiency particulate air filter attached to the second high efficiency particulate air filter, and a fourth high efficiency particulate air filter attached to the third high efficiency particulate air filter.

Abstract: A UV photocatalytic air purifier/sterilizer in which the multiple limited-lifetime components (such as the UV light, UV light electronics, and catalytic portion) of a photocatalytic UV air purifier/sterilizer are packaged together to form a single, handheld, unitized package, designed for easy insertion and removal into an air purifier. The invention may be configured enable maximum air flow through the photocatalytic portions of the device, thus further improving air cleaning efficiency by allowing many volumes of room air to be recirculated through the device and cleaned/purified/sterilized over the course of a day. In a preferred embodiment, the device may package a series of stacked TiO2 coated parallel metal catalytic plates, a UV germicidal lamp with a fluorescent tube form factor, and a UV lamp ballast into a single disposable or recyclable unit. This disposable unit can be easily clipped into a motorized air purifier unit designed for rapid servicing.
