A photocatalyst filter is provided. The photocatalyst filter includes: a base in which an internal space is formed. The internal space is permeable to fluid, and a plurality of photocatalyst beads are provided in the internal space, wherein a surface of the internal space is reflective.

Photocatalyst filter and air conditioner including the same

An air conditioning device is disclosed. The present air conditioning device comprises: a photocatalytic filter including a space through which air can pass and having a transition metal oxide formed in a nanotube form on the surface thereof, the transition metal oxide removing gases included in the air and including at least one of TiO, ZnO, NiO, and WO; and a light source for emitting light to the photocatalytic filter.

Photocatalytic filter and air conditioning device comprising photocatalytic filter

Disclosed is a method for manufacturing a photocatalytic filter for air purification. The present manufacturing method comprises the steps of: oxidizing a titanium metal to obtain a nanostructured titanium dioxide (TiO2); adding the nanostructured titanium dioxide to an acidic fluorine-containing solution to allow a reaction to occur therebetween for a predetermined period of time; and, after treatment in the acidic fluorine-containing solution, performing heat treatment on the nanostructured titanium dioxide.

Method for manufacturing photocatalytic filter for air purification

A bio marker detection device and a method for detecting or generating a bio marker from a plurality of strip sensors are provided. The bio marker detection device includes a close-up lens for detecting an image for the plurality of strip sensors, a transparent frame surrounding the close-up lens to evenly pass light from an outside to the plurality of strip sensors, and a strip sensor holder inlet configured for combining the plurality of strip sensors with the bio marker detection device. The method includes detecting a plurality of bio markers from a plurality of sensors, generating user health information based on the detected plurality of detected bio markers, and displaying the generated user health information.
