28 verified air coolers are rated by their own manufacturers for 200 sq ft and above, up to 400 sq ft. They run from ₹6,199 to ₹15,500.

This page filters on the rated floor area the maker publishes, not on tank litres. That distinction matters: a 90 litre tank tells you how long the cooler runs between refills, and nothing about how much air reaches the far corner of the room. Where a brand publishes no rated area, its models are excluded from this page rather than assumed to fit.

Ceiling height and ventilation change the answer as much as floor area does. An evaporative cooler needs an open window or door to work at all, so a room you cannot ventilate is a room where a cooler will disappoint whatever its rating says.

How we chose these

Rated area, published by the maker

Every model here carries a floor area figure from its own manufacturer. We do not calculate one from tank size, because that relationship does not hold across formats.

Ventilation is part of the sizing

A cooler pushes humid air in and that air has to leave. In a sealed room, humidity climbs until evaporation stops — which is why an 'undersized' cooler is often a badly ventilated one.

Frequently asked questions

Which air cooler is best for 300 sq ft room?
28 models are rated for it, from ₹6,199 (Orient Electric Aerocool Portable) to ₹15,500. Tanks run 23-160 litres. Prefer one that publishes an air-delivery figure over one that publishes only a tank size.
How many litres do I need for this room?
Litres is the wrong axis. Size on the rated floor area and the published air delivery; tank size then decides how often you refill. As a rough guide, a personal cooler suits up to about 200 sq ft, a desert cooler 300-700 sq ft, and anything larger belongs to the industrial formats.
Will one cooler do the whole flat?
No. Cooled air does not travel through doorways any better than purified air does. A cooler treats the room it is in, and the room needs its own ventilation path.
