    摘要： An air filter assembly 10 is disclosed. The assembly includes a filter frame 60 including at least one of a sigma ‘Σ’ convex shape and a V-convex shape and configured to accommodate at least two frames, using frame on frame design, to achieve maximum surface area, minimum air pressure drop, minimum filter rack material and save installation space. The filter frame includes at least three stage filter media 30 including a pre-filter 40 configured to filter coarse dust particles of a predefined size. The at least three stage filter media include a carbon filter 50 configured to eliminate formaldehyde, odors and volatile organic compounds in the air and improve air quality suitable for breathing. The at least three stage filter media include a fine filter 60 configured to remove bacteria, pollen, fine dust and aerosol of predetermined size from the air. The assembly includes a filter rack 70 configured to accommodate a predefined number of filter frames to overcome expected deflection of the at least three stage filter media.

    摘要： The present invention relates to a water filter comprising: a water filter cartridge including a water filter cartridge body, a water filter cartridge outlet cap having a water filter cartridge outlet, and a water filter cartridge sealing cap. The water filter cartridge body in a hollow cylinder form with a central hollow space, one end of the water filter cartridge body is coupled with the water filter cartridge outlet cap so that communicating with the water filter cartridge outlet, and the another end of the water filter cartridge body is coupled with the water filter cartridge sealing cap. The water filter cartridge outlet in a hollow cylinder form protruding from one surface of the water filter cartridge outlet cap. The filter container for containing the water filter cartridge therein, wherein the filter container including a filter container body, a filter container cap, a filter container inlet, and a filter container outlet, wherein the filter container inlet and the filter container outlet arranged at a filter container body bottom. The filter container body having a filter container outlet cylinder hole provided at the filter container body bottom for receiving the water filter cartridge outlet, so that when water flows into the filter container through the filter container inlet will surround the water filter cartridge and flows through the water filter cartridge body into the central hollow space of the water filter cartridge body, and flows to the filter container outlet through the water filter cartridge outlet. The filter container body having ribs provided at an inner surface of the filter container body bottom to reinforce for the filter container body bottom and providing gaps placed between the inner surface of the filter container body bottom and the outer surface of the water filter cartridge outlet cap, so that replacements or miscellaneous uses of the water filter cartridges become impossible.

    摘要： An object of the present invention is to provide a method for producing a propionic acid derivative with high productivity. The object can be achieved by a method for producing a compound represented by formula (1): wherein R1 is a halogen atom or the like, R2 and R3 are each independently a hydrogen atom, a halogen atom, or an organic group, X is an oxygen atom or a sulfur atom, R4 and R5 are each independently a hydrogen atom, a halogen atom, or a hydrocarbon group optionally having one or more substituents, RE is a hydrocarbon group optionally having one or more substituents; the method comprising step A of reacting a compound represented by formula (2): with a compound represented by formula (3): M(R1)n, wherein M is a cation, n is an integer corresponding to the valence of M, and a compound represented by formula (4): R6—X—H; and step B of separating, by filtration, the compound represented by formula (5): MFn from the mixture obtained by the above reaction.
