A soft medical silicone edged cushion may significantly reduce air leakage and provide comfort to a wearer of a face mask, for example, when the face mask is continually worn by a healthcare worker for a twelve hour shift of medical duty. The cushion may preferably be U-shaped and comprise a cross-section for holding an extra soft silicone gel or air, yet be sufficiently hard and elastic and of predetermined circumference to be adaptable to self-installation to the lateral edges of a face mask and coatable to protect from the escape of air and fit comfortably on a face despite the use of elastic straps with the face mask or the presence of solid plastic lateral edges of an oxygen mask or a ventilator mask. The cushion may be used to cushion a solid plastic laterally edged oxygen or ventilator mask against the use of elastic ties to tie the face mask around a patient's head. The face mask may comprise a UVC source of ultraviolet light controlled by buttons/displays/battery/USB port on the cushion or on a cartridge replacing a filter of an N95 mask.

An apparatus and methods for air filtration are disclosed. The apparatus includes a body and first and second replaceable filters. The body of the apparatus further contains an air-exchange assembly and a filter receiver attached to the air exchange assembly. The air-exchange assembly contains an exhaust tube with an open end and a closed end, two wings on opposite sides of the exhaust tube, and an intake check valve and an exhaust check valve inside the exhaust tube. The first replaceable filter surrounds the filter receiver; and the second replaceable filter is inside the filter receiver. Several apertures and the check valves are strategically disposed in the exhaust tube to achieve optimal air filtration and avoid contamination of a user's exhaust.

An illustrated view of an exemplary improved respirator mask for removing exhaled air from the respirator mask is presented. The respirator mask is useful for providing for the exhaling of air during respiration therapy to be released from the respiration mask to avoid a backflow of the exhaled air. The exhaled air has carbon monoxide, moisture and heat, thus the respirator mask allows for the removal of the carbon monoxide, moisture and heat preventing complications and improving the functionality of the respiration therapy.

A personal entertainment respiratory apparatus provides air to a user to provide a fully immersive entertainment experience. The personal entertainment system may comprise a flow generator for providing the flow of air. A personal spatial respiratory interface may be coupled to the flow generator. The personal spatial respiratory interface may comprise an outlet for the flow generator. The personal spatial respiratory interface may further be configured to direct the flow of air within an ambient breathing proximity of a user. The personal entertainment respiratory apparatus may further comprise a controller and a sensory particle dispenser. The controller and sensory particle dispenser may be configured to selectively activate release of a sensory particle from the dispenser into the directed flow of air in response to an entertainment triggering signal.
