A dust-filtering window screen that can be quickly installed, removed and replaced (Patent Pending). From the very beginning of the design, this system has followed the principles of "engineering thinking" and "user self-maintenance", turning the window screen from a "repair item" into a "consumable".

Revolutionary “Refill” Structure Pull out new screen from the upper roller box, lock the four edges and cut off the old one. Users can renew the window screen by themselves in minutes every week.	High-Efficiency “Dust Filtration” Standard Made of ultra-thin, high-density breathable material, it effectively blocks catkins, pollen and PM2.5 - keeping out both mosquitoes and dust.
“No-Drilling” Quick Installation The innovative hook-and-card system fits all kinds of window frames without damage, installing in seconds - ideal for construction projects.	Artistic “Scroll” for Every Home The screen supports customized patterns, turning the window screen into a decorative element of building facades.

I. Industry Pain Points

• After handover, screens get dirty and are hard to maintain - is your property complaint rate high?
• Do traditional screens, with their single function, fail to meet owners’ demand for air purification?
• Is batch installation inefficient, with labor costs remaining high?

II. Our Solution

• [Lower Long-Term Maintenance Costs] The screen becomes a “consumable” instead of a “repair item”: owners can replace it quickly by themselves, and property management no longer needs tedious after-sales repairs for dirty screens - greatly reducing life-cycle maintenance costs.
• [Enhance Project Value] The dense dust-filtering screen (e.g., gauze material) significantly improves indoor air quality while ensuring ventilation - a cost-effective selling point for healthy housing. Artistic customized screens further elevate the overall taste of the project.
• [Suitable for Batch Installation] The modular design plus a hook-and-card, no-drilling installation system allows one standard product to fit actual window frame sizes varying within 50mm, greatly improving on-site installation efficiency and shortening the construction period.

III. Cooperation Invitation (Two Models)

1. Authorized Production (Screen Rolls): Seek large gauze or filter-material enterprises to license this technology and produce standardized “screen roll” consumables, sharing the long-term dividends of the consumables market.
2. Technical Cooperation (Complete Window Production): Cooperate with real estate, building material and window & door manufacturers to license the patented technology and produce and sell complete “refill-style” dust-filtering window screens.
