A system and method for maintaining, monitoring and improving air quality and purity in a room or environment, such as a hospital room or operating room.

A spray booth especially adapted for painting operations having a dry filter module with features for allowing changing of the filters quickly and in a contained environment, which reduces exposure to non-authorized and non-properly-protected personnel. A carousel-like filter module flips a wall to move dirty filters into a containment space while placing clean filters in position to continue the painting process. The process and device in accordance with this invention is safe, repeatable, predictable, and capable of changing a large number of filters in a short period of time, for example, during lunch break or other short break in the painting operation.

Disclosed is a method of predicting the lifespan of a filter in an air cleaner based on machine learning. According to an embodiment of the present disclosure, a machine learning-based filter lifespan prediction method may more precisely predict the lifespan of a filter in an air cleaner by inputting fine dust concentration data and a history related to use of the air cleaner to a lifespan prediction model and determining the purifying efficiency and exchange time of the filter according to an output value. Intelligent air cleaner of the present disclosure can be associated with artificial intelligence modules, drones (unmanned aerial vehicles (UAVs)), robots, augmented reality (AR) devices, virtual reality (VR) devices, devices related to 5G service, etc.

The present invention relates to a filtering device for removing particles from a bodily fluid of a patient, the filtering device being implantable in the patient's body. The device has a tube forming a main fluid passageway for bodily fluid, through which the bodily fluid of the patient passes when the tube is implanted in the patient, a filter connected to the tube and a filter cleaning device for cleaning the filter by moving particles collected by the filter out of the fluid passageway, wherein the filter cleaning device is adapted to replace the first filter in the fluid passageway with a second filter, thereby moving the particles collected by the first filter out of the fluid passageway.

A filter element is provided. The filter element includes a filter media pack including an outer surface. The outer surface extending between a first flow face and a second flow face. The filter element also includes a polymeric coating applied to the outer surface of the filter media pack, wherein the polymeric coating is not a molded structure. In embodiments, the polymeric coating covers at least 25% of a span between the first flow face and the second flow face and has an average thickness of between 0.005 and 0.100 in. In other embodiments, the polymeric coating has a surface roughness of at least 50 pin to provide an outer gripping surface. A method and system for applying the polymeric coating to the filter element are also provided.

The present invention discloses an air purifier, including: an air intake structure and an air discharge structure. The air intake structure is connected and fixed to the air discharge structure via a quick-release structure, the air intake structure is provided with a filter screen, and placement/removal of the filter screen is enabled through engagement/disengagement of the quick-release structure. The air purifier of the present invention has a simple structure and a rational design. The air purifier is divided into two parts, namely an air discharge structure and an air intake structure which are arranged one above the other, and quick dismounting and mounting of the upper part and the lower part are enabled by means of the quick-release structure, thereby realizing quick and easy replacement of the filter screen, and effectively improving the replacement efficiency. In addition, the air purifier has a simple and attractive appearance.

Air cleaner assemblies, components therefor, and features thereof are described. Also described are methods of assembly and use. In depicted examples, the air cleaner assemblies and components optionally use advantageous housing seal features. Methods of assembly and use are described.
