Alum as a Cooling Water Solution
One of the easiest ways to improve cooling is by using fitkari (alum) in the cooler water. It says that adding a small piece of alum helps clean the water and improves overall cooling performance. Alum works by removing dirt and tiny particles from water. It causes these particles to settle at the bottom, leaving cleaner water above.
How Alum Cleans Water
Alum causes dust, dirt and minute particles present in the water to clump together. This process helps keep the water clearer for a longer time, which improves airflow from the cooler.
Reduces Smell And Improves Hygiene
Another important benefit mentioned is that alum helps reduce bad smell from stagnant water. In hot weather, water stored in coolers can start smelling due to bacteria growth. The article explains that alum helps slow down this process, making the air fresher and cleaner.
It also notes that mosquitoes often breed in stored cooler water. By adding alum, the chances of mosquito larvae growing inside the tank are reduced. This makes the cooler more hygienic and safer to use in homes during summer.
Better Cooling Efficiency
Clean water helps cooling pads work better. When pads are not blocked by dirt, they absorb water properly and release cooler air into the room. This improves the overall cooling effect of the cooler. Experts also advise that alum should be used in small amounts only, as too much can affect water quality. Regular cleaning of the cooler tank is still necessary for best results.
In conclusion, a simple and low-cost item like alum can help improve cooler performance. It keeps water cleaner, reduces smell, controls mosquitoes, and helps the cooler produce better air during extreme summer heat.
