Fits 5–5.9 inch exhaust hoses — insulated wrap that improves portable and window air conditioner performance, installs in seconds, and stays securely in place. Key benefits Better cooling performance: Triplelayer insulation reduces heat transfer through the exhaust hose so your room stays cooler and the air conditioner runs more efficiently. Lower energy waste: By minimizing heat gain from the exhaust hose, the wrap helps your HVAC system maintain set temperatures with less effort. Secure, custom fit: An adjustable strap system prevents slipping or shifting and lets you set the tension for a snug, stable attachment. Fast, tool installation: Designed for quick setup and removal so you can install the wrap without tools or professional help. What makes this product stand out Precise sizing: Specifically made to fit exhaust hoses 5–5.9 inches in diameter for reliable coverage and performance. Broad compatibility: Works with a wide range of portable and window air conditioners that use standard exhaust hoses in this size range. Durable, multilayer construction: Robust triplelayer insulation balances thermal performance and durability for consistent everyday use. How it solves common problems Stops heat bleed from exhaust hoses that counteracts your AC output. Prevents hose slippage that can reduce airflow efficiency or cause leaks. Means less frequent runtime from the air conditioner to reach comfort levels, helping reduce wear and energy consumption. Practical applications Home bedrooms and living rooms: Wrap the exhaust hose of a portable AC to keep rooms cooler while reducing energy use during hot months. Office or small commercial spaces: Improve comfort and temperature stability for work areas using portable cooling units. Apartments, RVs, and temporary cooling setups: Use the wrap where space is limited and a secure, compact, easytoinstall solution is needed.
