400cm Portable AC Window Seal Kit with Zip, Reusable Air Con Venting for Conditioner, Tumble Dryer and Dehumidifier, Self-Adhesive Conditioner

Effective Heat Barrier for Cooler Rooms: This window seal creates a closed barrier that stops warm outdoor air from flowing back into the room while directing exhaust heat from portable air conditioners or tumble dryers safely outside. The improved airflow helps appliances cool spaces faster, maintains stable indoor temperatures for longer periods, and reduces overall energy consumption during hot summer months. Insect and Rainwater Protection: The fabric cover seals the window opening completely, preventing flies, mosquitoes, spiders, and other insects from entering through gaps around the hose. A thick nano-layer resists rainwater penetration, keeping interior spaces dry during storms. The UV-resistant material withstands prolonged sunlight exposure without cracking, tearing, or losing its protective properties. Tool-Free Installation with Adhesive Tape: The kit includes 400cm of self-adhesive hook-and-loop tape, cable ties, and a printed guide. No screws, drills, or permanent modifications are needed. Simply clean the window frame, apply the tape around the perimeter, attach the seal, feed the hose through the zipper opening, and secure it with the supplied ties—installation takes just minutes. Durable Zipper for Hose Access: A heavy-duty zipper runs along the seal, allowing the appliance exhaust hose to pass through while maintaining a closed barrier. The zipper stays securely shut during operation and can be opened easily to remove the hose when the appliance is not in use. The window can be opened or closed at any time without removing the seal. Universal Fit for Multiple Appliances: With a 400cm perimeter, this seal fits most windows and works with all portable air conditioners, tumble dryers, and dehumidifiers that have a flexible exhaust hose. The durable, UV-resistant material can be reused multiple times—simply wash with water, air dry, and reapply for continued protection across seasons.
