This is possible with the Tristar AC-5555 universal window kit. The universal window kit is made of 100 % polyester and has a side dimension of 400 cm, so it fits most windows. It is very easy to fit thanks to the Velcro tape.

Durable material: Portable air conditioning units draw in warm, humid air, cool and dehumidify it and then return it to the room. A universal window set is needed to seal the rest of the window so that the cold air does not get outside and the warm air does not get into the room. This prevents the backflow of air and moisture. The window set is made of polyester. This makes it very resistant so that it can withstand heavy use.

Easy to install: The universal window set is very easy to install. Simply attach the Velcro tape to the inside of your window frame and fasten the insert to the Velcro tape. Then insert the hose of your air conditioning system through the opening in the fabric and close the zip so that the hose is firmly in place.
