Key benefits - Washable and reusable: The AC hose cover is easy to maintain. Remove from the hose, clean when needed, and reattach to keep protecting the system. This helps keep your air conditioning system clean and efficient over time. - Energy savings: The hose cover improves cooling efficiency and reduces cooling costs. In winter, silver warm air is used at the inlet and outlet to boost heating efficiency. By maintaining consistent temperatures and reducing system pressure, your AC or portable unit runs more effectively. - Durable materials: Made from aluminum film, cotton fabric, and Oxford fabric. The aluminum film reflects heat and provides insulation to prevent energy loss, while the cotton and Oxford fabrics offer durability and dust protection. - Easy installation and broad compatibility: About 59 inches long, it fits most brands with 5 inch or 6 inch diameter exhaust hoses. Installed with an adhesive method, it wraps around the hose without tools or complicated steps. In minutes you can seal the hose and be ready for optimal cooling performance. - Dustproof design: The soft cotton and Oxford fabric layers create a protective cover around the hose, shielding it from dust, dirt and debris. Helps prevent allergen and contaminant buildup for a cleaner, healthier environment. Materials and construction - Aluminum film: Insulation and heat reflection to minimize energy loss. - Cotton fabric and Oxford fabric: Provide durability and dust protection. Specifications and compatibility - Length: approximately 59 inches - Hose diameter compatibility: fits most 5 inch and 6 inch diameter exhaust hoses - Installation: adhesive wrap, no tools required Use scenarios - Summer cooling with portable air conditioners: protects the exhaust hose from dust and debris while improving efficiency. - Winter heating: enhances heating performance by using silver warm air at the inlet and outlet. - Dusty environments (garages, workshops): reduces dust and allergen buildup around the hose for a cleaner indoor air quality. Maintenance tips - Remove periodically to clean and inspect the inner surface. - Reinstall promptly to maintain protection and efficiency. - Check the adhesive seal to ensure a secure fit after cleaning.
