In summer, stepping out of the house can be a punishment. But staying indoors without a cooling system on can be equally daunting. You may be tempted to keep the air-conditioner on all day but the steep electricity bill at the end of the month is likely to make you sweat even more. This is when an air-cooler comes to your rescue.

Cost-effective, air coolers also consume less energy while keeping your home cool. And, they don’t look bulky anymore. Today, air coolers come in compact, sleek and sophisticated designs that go well with modern homes. If you are planning to buy one for your home during the summer, these pointers can help you make the right choice.

1. Be design and size wise

Air coolers are available in a variety of designs and sizes such as desert, tower, hybrid and more. Choose one that suits your cooling needs. If you have a bigger space, then a fixed unit, such as a desert cooler that offers strong cooling, will work well. A portable design, on the other hand, is compact, has wheels and is better at cooling smaller spaces.

To know what capacity or design will work well for your space, do this simple calculation. The airflow of an air cooler is measured in terms of CFM (cubic feet per minute). CFM tells you the amount of air cycled into your room each minute. If your room size is 300 sq, with the ceiling at a height of 10 feet, then the CFM required would be 1,500 (300 sq ft x 10 ft/2).

2. Go for energy-efficient coolers

Based on their design and cost, air coolers can vary significantly in terms of energy efficiency. You should always check the energy efficiency rating of the cooler you plan to purchase. You can also consider an air cooler with an inverter that saves energy.

3. Water capacity matters

Larger the water tank, the longer the air cooler will run without you having to fill it up again. Both desert and personal air coolers come with water tanks of varying sizes. While personal air coolers have tanks with 20-30 litre capacity, big desert coolers have tanks with 31-50 litre capacity.

4. Look for a thick padding

Before you zero in on an air cooler, check what kind of cooling pads it uses—they absorb water and allow the cool air to flow out. Thick cooling pads will allow better cooling. While most pads are made of either aspen or cellulose (honeycomb) material, the latter are thicker and last longer but may cost a little more than aspen pads.

Tip: If you live in a locality where power cuts are common, you can go for an air cooler than can run on an inverter too.
