Stop blaming your AC: The surprising reason air coolers cool small rooms faster (HT Tech)


When temperatures rise in summer, everyone almost instinctively turns to ACs for all their cooling needs. After all, the benefits are many. They reduce room temperature, manage humidity, offer low-noise operation and some models even clean the air while cooling the room. While this is true for medium and large rooms, ACs may not be the smartest cooling solution for smaller rooms. What works better for smaller rooms is a simple device called an air cooler.

AC vs Air Cooler: Which One to Choose?

Why? The reason is simple. AC reduces the room temperature gradually. Sure, they are effective. But they also take more time and consume more energy, resulting in higher electricity bills. Air coolers, on the other hand, use strong airflow to cool a space. This process is both faster and more energy efficient. For small rooms, this difference can be huge. Furthermore, air coolers have low upfront costs, cheap maintenance and are ideal for students, individuals and families who want to cut down on their electricity bills.

Individual, tower or dessert: which is better for small rooms?

So, if you have a small room to cool down and you are wondering which way to go, air cooler or AC, then air coolers provide a better option as they provide faster cooling at a lower cost. More specifically, buyers should opt for personal air coolers or tower air coolers as they are compact in size, offer quiet operation, and are highly energy efficient and portable. Desert air coolers, on the other hand, are designed for larger spaces and they can quickly make the room humid and stuffy. They occupy a lot of space compared to personal and tower air coolers.

So, now that we have decided which option is better, here is a list of the best personal and tower air coolers that you can use to cool a small room in your home.
