This is an insulating duct cover that efficiently blocks the hot air discharged from spot coolers and portable air conditioners.

The three-layer structure, combining aluminized film and foamed polyethylene, is designed to suppress the temperature rise around the exhaust hose.

It supports hoses with a diameter of 12.7cm to 15cm and has a flexible design that easily conforms to curved ducts.
Heat does not easily build up inside the cover, making it useful for improving the cooling environment indoors.
Installation is simple, just by tightening the opening with a string, and no special tools are required.

The surface is designed with consideration for water and stain resistance, accommodating the adhesion of dust and water droplets.
After use, it can be folded for space-saving storage.

This is a practical item that supports the creation of a cooling environment indoors, for those who want to improve the efficiency of air conditioner exhaust and take measures for cold air circulation.
Improve duct exhaust efficiency and exhaust is OK just by applying.
