Abstract

The subject of the application is a window air supply device having an air supply vent (1) with an adjustment diaphragm (2), a drip cap (3) and a connecting tunnel, characterized in that the connecting tunnel is divided into two parts, an air supply part (4a) and a drip cap part (4b) connected with each other by sockets, wherein a removable filter insert (5) with a filter is located in the air supply part (4a). The method of preparing a filter insert for window air supply devices consisting in applying a modifier to an agrotextile is characterized in that 1,4-butylene polyadipate-1,4-butylene coterephthalate is dissolved in chloroform in a ratio of 10 g per 100 ml, mixed with a stirrer and heated to a temperature of 60°C, and then 0.01 g of diatomaceous earth and 0.002 g of finely ground onion peel are added and the additives are ground using a mortar for 15 minutes, after which the prepared composition is applied to the filter surface using a sprinkler.
