ZORVINEX Portable Air Conditioner Window Vent Kit, Adjustable Hose Cloth for Mobile AC Units, Waterproof and Easy Installation, Fits Sliding Windows, Improves Cooling Efficiency White

This portable air conditioner window vent kit provides an efficient and tool-free solution for sealing window gaps while exhausting hot air from your mobile AC unit. The set includes a round hose opening with an elastic cuff that fits standard exhaust hose diameters tightly, eliminating the need for extra adapters. Made from thickened, tear-resistant waterproof polyester fabric, it effectively blocks outdoor heat and prevents cool air leakage, boosting your air conditioner's performance and reducing electricity bills. The extra-long flexible cloth panel (available in 200×50cm or 300×50cm) adapts to vertical sliding, horizontal sliding, and casement windows without cutting, making it suitable for homes, apartments, dorms, and RVs. Installation requires no drilling or screws—simply clamp the cloth between window sashes, attach the exhaust hose to the elastic sleeve, and finish in minutes. When not in use, the foldable design allows compact storage, and the reusable fabric is stain-resistant and easy to clean with a damp cloth. This durable, aging-resistant kit ensures a tight seal summer after summer.
