An anti-mosquito window can prevent mosquitoes and flies; to facilitate ventilation, thin filaments are needed to manufacture the screen mesh of the anti-mosquito window; however, the thin filaments are low in strength and short in service life; to improve the strength and prolong the service life, thick filaments or plate punching needs to be adopted, but thick filaments or the plate does not facilitate ventilation. A sheet or strip is adopted to manufacture the screen mesh of the anti-mosquito window, wherein the thickness of the sheet or strip is less than that of the thin filaments, and the width of the sheet or strip is far greater than that of the thin filaments; the width direction of the sheet or strip is perpendicular to the window plane, so that the ventilation quantity of the anti-mosquito window is increased, and the strength of the anti-mosquito window is also improved; in addition, the anti-mosquito window has another advantage: as we all know, the sunshine in summer realizes perpendicular incidence, the sunshine in winter realizes oblique incidence, the sunshine at noon realizes perpendicular incidence, and the sunshine in the morning and afternoon realizes oblique incidence; the anti-mosquito window is mainly composed of horizontal sheets; the horizontal sheets block more direct light and blocks less oblique light, so that favorable effect is generated on the indoor temperature and illuminance; and in addition, latitude lines are made to be oblique outwards and are slightly increased in width, so that the anti-mosquito window has certain rainproof function and drizzle is unlikely to enter indoors.
