About this item
  • 📏 [Measure First for the Perfect Fit!] Before buying this air conditioner window seal, please watch our video to learn how to measure your window length (up to 400cm) and check compatible shapes. Essential for an ac window seal kit uk outward window to ensure a flawless installation!
  • ❄️ [Universal Dual & Single Hose Design] Our air con window seal kit fits both dual and single hose systems! Using one hose? Simply pull the unused zip fully to the bottom to close it completely. After fully zipping the zipper tight against the exhaust hose, take one nylon cable tie, thread it through the hole in the zipper slider, wrap it once around the edge of the adjacent window seal fabric, then pull tight and lock it firmly. A versatile window seal for mobile air conditioner to lock your air conditioning unit securely.
  • 🛡️ [Premium Oxford Cloth & PU Coating] Stop hot air returns! This waterproof window seal uses heavy-duty Oxford cloth with a PU coating. Better than a standard portable ac window seal, it keeps your room cooler, saves energy, and efficiently blocks rain or summer bugs from entering.
  • 🛠️ [No Drilling, Effortless Installation] Renters love this no drill window seal! Just stick the hook tape to your frame, attach the ac window kit, insert the hose outdoors, and tighten the drawstring. The ultimate window kit for portable ac and tumble dryer window seal setup!
  • 🌿 [Eco-Friendly Cooling for Any Room] Lower your electricity bills with this energy saving window seal! Perfect for bedrooms or offices, this portable air conditioner window kit stops warm drafts. Compatible with most UK windows, this zip window seal is a summer must-have!

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
