Buying Guide for Window Seals for Portable Air Conditioners
Choosing the right window seal for your portable air conditioner involves several key considerations to optimize performance and comfort:
Window Type Compatibility
- Sliding windows: Most window seals are designed for horizontal or vertical sliding windows (single- or double-hung). Ensure the product specifically states compatibility.

- Universal compatibility: Some seals offer adjustable and flexible design to fit multiple window types.
Exhaust Hose Diameter
- Measure your AC exhaust hose diameter; common sizes range from 5.9 to 6.8 inches.
- Select a seal with adjustable hose fit or size matching your unit to ensure tight sealing and prevent air leaks.
Material and Durability
- Waterproof fabrics: Essential to protect against rain and moisture ingress.
- Heat insulation and reflective coatings: Silver or specialized coatings reflect sunlight and reduce heat transfer.
- Strong fastening: Velcro, zippers, or drawstrings should be sturdy and provide a tight fit without failure or slipping.
- Wear-resistant panels: Durable materials like thickened PVC prevent damage from sun exposure and hose heat.
Installation and Adjustability
- Choose window seals with straightforward installation methods such as adhesive backing, Velcro, or zippers.
- Length adjustability ensures compatibility with various window sizes and makes trimming easier.
- Seamless designs or embedded grooves help eliminate gaps that reduce sealing efficiency.
Energy Efficiency and Cost Savings
