A device for removal of particulates from a gas is provided. The device comprises: an inlet for receiving a flow of gas; an outlet from which the flow of gas can be expelled; and a labyrinthine path extending between the inlet and the outlet for passage of the flow of gas; wherein the labyrinthine path is arranged to steer the flow of gas such that particulates in the gas will impact on adsorption surfaces of the labyrinthine path arranged for adsorption of impacted particulates such that particulates in the gas are removed from the gas by impaction on the adsorption surfaces as the gas flows from the inlet to the outlet. The device may be part of a face mask. The volume of air in the device with a velocity magnitude below 1 ms−1 may be greater than 4% of the total volume of air in the device.
A face mask comprising a device for removal of solid particulates from a gas, the device comprising:
A face mask according to any preceding claim, wherein the device has a continuous gas path from the inlet to the outlet.
A face mask according to any preceding claim, wherein the labyrinthine path is arranged to steer the flow of gas through and/or past multiple turns and/or branches with changes in the flow direction of at least 90 degrees.
A face mask according to any preceding claim, wherein the walls of the labyrinthine path include surfaces extending along the principal flow direction and surfaces that are at least 90 degrees relative to the flow of gas, such that particulates in the flow of gas impact on the walls of the labyrinthine path.
A face mask according to any preceding claim, wherein, in use, the gas does not pass through a fluid.
A face mask according to any preceding claim, wherein the face mask does not comprise a filter.
A face mask according to any preceding claim, wherein the path comprises branches that are for the capture of particulates rather than for through-flow of the gas.
A face mask according to any preceding claim, wherein the device comprises baffles.
A face mask according to any preceding claim, wherein the gas flow path of the face mask includes a bend of between 90-180 degrees after the labyrinthine path.
A face mask according to any preceding claim, wherein the face mask comprises bristles that are located across the path at, or near, the inlet of the device.
A face mask according to any preceding claim, wherein the walls of the gas flow path are made of acrylonitrile butadiene styrene (ABS).
A face mask according to any preceding claim, wherein the device has a removable cover to aid cleaning of the labyrinthine path.
A face mask according to any preceding claim, wherein the device has dimensions of 5 to 15 cm, by 5 to 15 cm, by 0.5 to 5 cm.
A face mask according to any preceding claim, wherein the face mask comprises a second device for removal of solid particulates from a gas, the second device comprising:
A method of removing particulates from a gas, the method comprising:
A device for removal of particulates from a gas, the device comprising:
A method of removing particulates from a gas, the method comprising:
