As summer temperatures soar across the UK, many people rely on fans to stay cool indoors. However, fans are not designed to lower room temperature—they simply circulate air to evaporate sweat, providing only temporary relief. A simple kitchen hack can make fans significantly more effective, turning them into a true cooling solution.
How a Frozen Milk Carton Boosts Fan Performance
Vikki from Lifestyle Homecare Services explains that placing a frozen milk carton in front of a fan can dramatically improve its cooling power. “All you need to do is add something cold/frozen in front of the fan and the air being circulated should be much cooler than before,” she says. “Freeze an old carton of milk filled with water and sit it in front of the fan.”
The science behind this trick is simple: as the fan blows air over the frozen carton, the ice absorbs heat from the air, cooling it before it reaches you. This process also reduces the overall heat in the room, making the environment feel less stuffy and more comfortable.
Why Milk Cartons Work Best
While any frozen container can be used, milk cartons are ideal because of their larger surface area and capacity. A standard milk carton holds more liquid than a typical water bottle, allowing it to absorb more heat and stay frozen longer. This means the cooling effect lasts for hours, providing sustained relief during hot weather.
To prepare the carton, fill it about three-quarters full with water—leaving space for expansion as it freezes. Place it horizontally in the freezer until solid. When ready to use, set the frozen carton on a towel to catch condensation, then position it a few inches in front of the fan. Ensure there is a gap to prevent moisture from reaching the fan's motor.
Simple Steps for a Cooler Home
This method is a cost-effective, energy-efficient way to beat the heat without relying on air conditioning. It works best in small to medium rooms and can be repeated with multiple cartons for larger spaces. For optimal results, use the fan on a low or medium setting to allow the air to cool gradually.
As temperatures continue to climb, this kitchen hack offers a practical solution for staying cool without expensive appliances. With just a milk carton and a fan, you can create a refreshing breeze that truly lowers the temperature in your home.
