A universal bubble facial cleaning instrument with a purification apparatus relates to the technical field of bubble facial cleaning instrument devices. A water purification mechanism is arranged in a middle outer member, one end of the water purification mechanism is connected with a bubble generator, a composite filter element is rotatably arranged in a filter element groove member, a front end of the filter element groove member is hermetically provided with a filter element bottom cover, an outlet section at a tail end of the filter element groove member is provided with a fixed edge with one side close to the composite filter element provided with a gap blocker, a tail end of the middle outer member is provided with a water outlet outer member clamped with the fixed edge, and a bubble outlet of the bubble generator is exposed from a bottom opening of the water outlet outer member.

A photothermal composition configured to be used in air filter for destroying bioaerosol particles by converting light energy emitted from a light source into heat energy including a photothermal agent is provided. The present invention also concerns an air filter for collecting the bioaerosol particles in an air flow and destroying said bioaerosol particles deposited thereon, including a photothermal agent which converts light energy emitted from a light source into heat energy.

The present disclosure provides devices and methods for filtering a fluid. An example device can include a first end configured to be joined to a first segment of a pipe. The first end can include a first opening for receiving the fluid. The device can also include a second end configured to be joined to a second segment of the pipe. The second end can include a second opening for transmitting the fluid. A filtering segment can be disposed between the first end and the second end. The filtering segment can include a plurality of fiber filters oriented substantially perpendicular to a direction of flow of the fluid in the pipe. A fiber filter of the plurality of fiber filters can include a mycomaterial and a carrier material configured to provide nutrients to the mycomaterial.

An anti-propylene mask and method for preparation thereof is provided; the anti-propylene mask includes a fiber cloth contact layer, an antistatic non-woven fabric layer and a fullerene/nano titanium dioxide spunbond layer which are arranged in sequence; the fullerene/nano titanium dioxide spunbond layer is made by spun-bonding the modified resin material into a fiber web; the raw materials of modified resin materials include matrix resin, carboxylated fullerene derivatives, nano titanium dioxide, a lubricant, and a coupling agent; the modified resin material is prepared by following method: the carboxylated fullerene derivative is mixed and reacted with the nano titanium dioxide to prepare the carboxylated fullerene derivative-modified nano titanium dioxide, which is then blended and extruded with the remaining components in the raw material, and thus prepared. The mask can prevent propylene from entering the human body through the human respiratory organs and has a good anti-propylene effect.

Disclosed is a shower filter element. The shower filter element includes a filter assembly and a detachable upper end cover and a detachable lower end cover which are located at two ends of the filter assembly, the filter assembly sequentially includes a first-stage filter element composite layer, a second-stage filter element composite layer and a third-stage filter element component from outside to inside, the first-stage filter element composite layer sequentially includes an inner support layer, at least one micron-sized filter layer and an outer support layer from inside to outside, the second-stage filter element composite layer sequentially includes a support filter layer and a composite carbon fiber layer from inside to outside, the third-stage filter element component includes a filter container and a filter material arranged in the filter container. The present application achieves the effects of effectively filtering impurities in water, improving a filter effect and efficiency.
