The present invention aims to provide a sheet of microfiber assembly having a high filtering performance suitable as an oil-mist filter. A sheet of microfiber assembly 2 comprises microfibers 1 each having a fiber diameter of 3,000nm or less and is formed of a mixture of water-insoluble but alcohol-soluble acetalize...

A purified air discharge device is provided with a push hood (2) which has an air flow discharge surface (23) for discharging a uniform flow of purified air. The push hood (2) is provided with a side air discharge section (28) which causes a flow of purified air to strike a peripheral wall which is formed when the p...

A local air cleaner (1) is configured in such a manner that a uniform current of cleaned air discharged from an air current opening surface (23) and contacts an air contact surface (W) and flow to the outside of an open region , thereby maintaining the insides of a guide (3) and the open region at a cleanliness leve...

In a mask device with blower, a sensor (15) for warning is disposed, which detects a movement position (d2) of an exhaust valve (7) corresponding to the case where an internal pressure of a face body is lower than an outer atmospheric pressure at the time of inhaling air in a non-contact state and outputs a sig...

The present invention relates to an air cleaner capable of predicting the breakthrough time of a filtering unit. The air cleaner, for example a mask (1), inputs concentration data of toxic gas components included in air (40) upstream of the filtering unit (3), flux data of the air (40) passing through the filtering ...

An air blowing device adapted to be used in such a manner that at least two of the devices are horizontally and/or vertically aligned with each other, thereby to obtain a uniform flow of air in the downstream direction from device to device. An air-permeable front surface (11f) is formed to the blowing device (1) a...

Disclosed is an air blowing device that, when using the air blowing device arrayed horizontally and / or vertically, can obtain a uniform flow of air in the downstream direction from device to device. An air-permeable front surface (11f) is formed to the blowing device (1) at the downstream side of a rectifier mecha...

Provided is a mask provided with a latch that can maintain a latched state of a fastening cord and suppress offsetting when the mask is worn. A latch (10) for a mask (1) has a wide thin plate shape and includes a first latching part (20) for latchably and releasably latching one fastening cord (4) of the mask (1) ...

[Problem] To provide a mask capable of ensuring good contact with the face of a wearer. [Solution] A mask 1 comprises: a filter part 2 that is formed of an air-permeable sheet material and covers at least the nose part and the mouth part when the mask 1 is worn; an almost annular face contact body 3 that is joined t...

ABSTRACT The local air cleaning apparatus 1 causes a cleaned uniform air flow blown out from an air flow opening face 23 to collide with an air collision face W to flow outside an 5 open region, so as to cause cleanliness to be higher inside a guide 3 and inside the open region than other regions. Additionally...

[Problem] To provide a mask with which it is possible to easily form a three-dimensional shape that can ensure a favorable contact with a wearer’s face during use, and easily maintain a favorable use state. [Solution] A mask 1 comprises a mask body 2 exposed to the outside and ear loops 4, 4 on both sides of the mas...
