When summer arrives, rising temperatures become hard to ignore. Living without an AC or cooler can feel uncomfortable. While ACs may not suit every budget, air coolers are a more affordable option and widely used during the season.

Coolers often run for long hours in summer, but sometimes they start giving off an unpleasant smell. If your cooler smells bad, it can make the air uncomfortable and affect your overall experience at home.

It is quite common for coolers to develop a bad smell after a few days of use. This usually happens due to stagnant water, dust, fungus or bacteria. The issue is more likely if old water is reused regularly. The good news is that simple home remedies can help fix this without using expensive chemicals.

Start by cleaning the cooler tank thoroughly. Drain out all the old water and wash the interior with clean water. You can also add a bit of vinegar while cleaning, as it helps reduce bacteria and minimise odour.

Do not overlook the cooling pads. Dust buildup in the pads can cause unpleasant smells in the air. It is best to remove and wash them regularly, or replace them if they are too worn out.

A simple trick is to use baking soda. Adding a small amount to the water can help absorb odours. Lemon juice can also add a natural freshness. Some people use mint or clove oil, but these should be added in small quantities to avoid overpowering the air.

Changing the water frequently is essential. Ideally, replace the water completely every two days to prevent bacterial growth. Keeping the cooler in a well-ventilated area also helps, as closed spaces tend to trap bad odours.

Regular cleaning, proper maintenance and the use of simple natural ingredients can keep your cooler fresh throughout summer. Small steps can make a noticeable difference in the quality of air you breathe. (Disclaimer: This article is based on general information only.
