<p>PROBLEM TO BE SOLVED: To remove formaldehyde vapor simply and inexpensively. SOLUTION: A mesh-shaped partition member 3 is installed on the upper side in a container body 2 having a ventilation part in the upper part, granulated calcium chloride 4 which can adsorb formaldehyde and absorbs moisture to be liquefied is placed on the partition member 3, the bottom side below the partition member 3 is constituted to be a liquid retaining part 5 for receiving the aqueous solution of liquefied calcium chloride 4, urea 6 which reacts with formaldehyde in the aqueous solution and solidifies formaldehyde is packed in the liquid retaining part 5, and formaldehyde generated in a closet, a wardrobe, a chest drawer, and others is caught so as not to be re-evaporated.</p> |
