xKeep warm air out, cool air in
When a portable air conditioner or tumble dryer vents through a window, warm air can creep back into the room. HOOMEE 400CM Universal Window Seal creates a controlled, closed environment by securing the hose between the window frame and the sash. This simple barrier helps your space stay cooler and reduces the chances of re-entry warm air without relying on heavy window kits.
Boost cooling performance and energy efficiency
By sealing around the open window and zip-closing around the hose nozzle, the system reduces backflow of warm air. The result can be faster cooling and steadier temperatures on hot days, with the setup designed to complement common portable units and tumble dryers, limiting drafts, rain, and pests from entering via the vent gap.
Easy setup and universal fit
- No drilling required: install quickly with the included adhesive hook tape on the inside of your window frame, then attach the seal and zip around the hose.
- Universal fit: fits windows with a maximum perimeter of 400 cm (157"), compatible with left- or right-opening styles, bottom-hung, and skylights.
- All-in-one solution: seals, holds the hose, and provides a tight zip closure around the nozzle for a clean, secure setup.
Everyday use and scenarios
- Weather protection: blocks rain and drafts while your cooling device operates, helping maintain a comfortable room ambiance.
- Device compatibility: suitable for portable air conditioners and tumble dryers, offering flexibility in usage scenarios.
- Energy-conscious potential: reducing unnecessary warm air circulation can help you use energy more efficiently during warm seasons.
In real-world spaces, HOOMEE offers a practical, non-permanent solution that fits a range of window styles. The installation is straightforward and gentle on windows, avoiding holes or complex hardware. The result is a neat, tidy setup that supports your cooling efforts without adding clutter or excessive noise.
What to expect during setup
Before you begin, measure your window’s perimeter to confirm the 400 cm maximum. Apply the adhesive hook tape inside the window frame, align the seal, and open the zipper to thread your hose. Close the zipper tightly for a seal that stays in place as you operate your appliance.
