- Effective Temperature Control: Our window seal kit prevents hot air from re-entering your room, maintaining a cooler environment. The waterproof design keeps out rain and pests, creating a closed space that retains cool air longer. - Innovative Design: Featuring an adjustable coupling instead of traditional zippers, this window seal ensures superior sealing and minimizes air convection. This upgrade helps reduce electricity costs during hot summer months. - Universal Compatibility: The AC exhaust hose gasket cloth fits all portable air conditioners and tumble dryers. It is compatible with windows that open left or right, tilt windows, and skylights (not suitable for sliding windows or doors), accommodating maximum perimeters of 2m/3m. Your windows remain fully operational for regular use. - Reusable and Durable: Made from high-quality, waterproof material, this window seal is lightweight and easy to store. It can be easily removed when not in use and conveniently reused in subsequent summers. Use Scenarios: 1. Home Cooling: Install the window seal with your portable air conditioner to enhance cooling efficiency and reduce energy bills during peak summer heat. 2. Laundry Room: Use the seal with a tumble dryer to prevent warm, humid air from flowing back into your living space, keeping your home comfortable. 3. Seasonal Use: Easily remove the seal during cooler months and reapply in warmer seasons, making it a practical solution for year-round temperature management.
