The present invention relates to a technique to prevent yellow dust or microdust from coming indoors by attaching the yellow dust or microdust to a roll screen composed of a non-woven fabric type absorbing material and a sticky material which can absorb extremely small particles. Also, an unused non-woven fabric for one time use is also arranged on the roll screen to allow a user to change a non-woven fabric when too much dust is attached to the roll screen. In addition, a fixating device for installation, and a lower fixating adhesive tape to fixate the entire window are attached to the roll screen. |
