【Easy to Use】: Simply prepare an adequate amount of blue ice boxes and place them in the freezer without adding water. After freezing for 4-8 hours (depending on the freezer temperature), remove the blue ice boxes and add them into your appliance's water tank until it covers the blue ice box.
These 6-pack freezer packs are ideal for providing consistent cool air during hot summer months, using your AC unit in a camper, boat, RV, or even a heated room.
