Faster room cooling - thanks to a sealed hose outlet
Zips close around the nozzle and locks the exhaust hose between the window frame and the window housing, preventing warm air from re-entering the room. Adhesive hook tape holds the seal in place without drilling.
Rooms reach comfortable temperatures more quickly and stay cooler for longer, helping portable air-conditioners work more efficiently.
Weather and pest protection - with a full zip enclosure
A fabric window bag zips tightly around the hose and forms a barrier at the window edge, blocking insects, mosquitoes and rain. The sealed edge creates a 'closed environment' that limits external air ingress.
Keeps insects and moisture out so interiors remain cleaner and more comfortable while the appliance runs.
Quick, tool-free installation - with adhesive hook tape
Adhesive hook tape is applied to the window frame and the window bag, then the bag attaches to the tape and zips around the hose. No drilling or additional window kit is required.
Fast to fit and removable when not needed, with compatibility across multiple window orientations and opening styles.
