Key benefits Reduces heat transfer from the exhaust hose to keep indoor temperatures more stable. Helps your air conditioner run more efficiently, which can reduce runtime and lower energy use. Smooth, wrinkle fit for neat installation and reliable insulation performance. What it is A triplelayer hose cover made from acrylic fabric, cotton cloth, and EVA foam that surrounds portable AC exhaust hoses to limit heat exchange between the hose and your room. Materials and construction Triple layered insulation: acrylic fabric (outer), cotton cloth (middle), EVA foam (inner). This combination provides a soft, flexible barrier that resists heat flow while remaining easy to handle and install. Size and compatibility Dimensions: 60 inches long and 20 inches wide. Fits exhaust hoses with diameters from 5 inches to 9 inches. Extra length can be folded to adjust the fit as needed. Performance and function Minimizes heat transfer from the exhaust hose into the room, helping maintain a comfortable indoor climate. Designed to improve overall cooling efficiency by reducing unwanted heat gain near the appliance. Soft construction prevents awkward folds or wrinkles for a smooth, professional appearance and consistent insulation coverage. Installation and care Wraps easily around standard portable AC exhaust hoses and secures in place; any excess length can be folded for a tidy fit. Lightweight and flexible for quick installation or removal when moving the unit. Practical applications Apartments and small homes: keep rooms cooler by reducing heat entering through portable AC exhaust ducts. RVs and boats: improve cooling efficiency in compact spaces where exhaust hoses run near living areas. Offices, workshops, or temporary cooling setups: maintain more stable indoor temperature around vents and portable units.
