Why People Add Alum to Air Cooler Water in Summer — Benefits You Should Know
Keeping an air cooler in good condition isn’t just about filling it with water—it also involves maintaining the quality of that water. Many households follow a simple, time-tested method of adding alum to the cooler tank. Though it may seem like a small step, it plays an important role in improving cleanliness, air quality, and overall performance of the cooler.
How Alum Helps Clean the Water
Adding alum to the cooler tank causes tiny dust particles, dirt, and other impurities in the water to bind together. These heavier clusters settle at the bottom of the tank, leaving clearer water above. Cleaner water not only improves airflow quality but also helps in keeping the internal components of the cooler in better condition.
Reduces Bacteria and Unpleasant Smell
Warm conditions often lead to bacterial growth in stagnant water, which can result in unpleasant odors from the cooler. Alum slightly changes the water’s pH level, making it harder for bacteria to thrive. This helps keep the water fresher for a longer time and reduces the chances of bad smells.
Useful in Areas with Hard or Salty Water
In places where water contains higher salt content, coolers can develop a white layer on cooling pads and fan blades. While alum doesn’t completely remove the salt, it helps some of the minerals settle at the bottom. This reduces buildup and helps extend the life of the cooling pads.
Helps Keep Mosquitoes Away
Standing water can attract mosquitoes if not maintained properly. Adding alum makes the water less suitable for mosquito breeding. After cleaning the cooler, you can refill it with fresh water and add a couple of small alum pieces or a few drops of neem oil to maintain better hygiene and air quality.
Extra Care Tips for Better Performance
If your cooler has a metal body, applying a coat of oil paint or using a rust-proof spray at the bottom can help prevent corrosion over time. Cleaning the fan blades with a damp cloth removes dust buildup, reduces pressure on the motor, and keeps the cooler running smoothly without unnecessary noise.
