HOOMEE 400CM Universal Window Seal for Portable AC
The HOOMEE Universal Window Seal is designed to effectively keep hot air from entering while sealing the exhaust hose of portable air conditioners between the window frame and the window itself. It creates a closed environment that enhances AC efficiency by preventing warm air return flow. The seal comes with a zipper that fits snugly around the hose, contributing to increased cooling performance. Made to reduce energy consumption, it supports eco-friendly living by lowering electrical costs and carbon emissions. This product is easy to install with adhesive fasteners and supports most window types with outward tilting openings.

Buying Guide for Air Conditioner Window Seals for Outward Opening Windows
Choosing the right window seal for your outward opening portable air conditioner window involves several factors to maximize cooling efficiency and comfort. Below are the key considerations:
- Window Compatibility: Confirm that the seal fits the type of window you have—casement, tilt, crank-out, or outward opening. Some seals work only with sliding windows, which won’t suit outward opening frames.
- Material Quality: Look for durable, waterproof, and UV-resistant materials such as nylon or TU fabric. Reflective coatings (like silver-plating) can improve insulation and reduce heat gain.
- Seal Mechanism: Zippers, drawstrings, and hook-and-loop tapes all secure the seal differently. Zippered seals often provide a tighter fit around AC hoses but require some care during installation to avoid damage.
- Ease of Installation: Select seals that don’t require permanent modifications like drilling. Adhesive fasteners and hook tapes simplify setup and removal.
- Size and Adjustability: Measure your window opening and hose diameter carefully to choose the right length and fit. Adjustable or cut-to-size seals provide more flexibility for non-standard windows.
- Environmental Impact: Using a good window seal can reduce energy consumption, lowering electricity bills and carbon emissions.
- Additional Features: Some products offer enhanced shading rates, waterproof coatings, or better durability, which can benefit performance and longevity.
