Room coolers sit between personal and desert formats: enough tank and throw for a standard bedroom or hall without the bulk of a desert unit. This page lists every room air cooler we could verify against the manufacturer's own price — 8 models from Voltas and Ram Coolers, running from ₹6,265 to ₹16,200.
Tanks here run from 35 to 90 litres. Tank size decides how long the cooler runs between refills, not how hard it cools — that is set by air delivery, air throw and the floor area the maker rates the unit for, all of which are shown in the table below wherever the brand publishes them.
8 of these 8 use honeycomb (cellulose) pads, which cool more efficiently than wood wool, last longer and rinse clean. Rated input power runs from 100 W to 100 W — at ₹8 a unit and ten hours a day through a 180-day season that is roughly ₹1,440 to ₹1,440 a year, against ₹18,000-plus for a 1.5 ton air conditioner run the same way.
Every price was read from the brand's own store on 18 September 2026. Amazon and Flipkart often sell below the brand store in a sale week, so use the links on each model to compare before buying.

How we chose these
Cooling reach, not tank size
We rank on air delivery in m³/hr, air throw and rated floor area first. A 90 litre tank only means fewer refills; it does not move more air than a smaller unit with a stronger blower.
Honeycomb over wood wool
Honeycomb pads hold more water per unit of airflow, resist clogging in hard water and can be rinsed rather than replaced. Wood wool is cheaper and is the media most likely to hold odour once it has been left damp.
Published specs only
Every figure comes from Voltas and Ram Coolers's own listing or product page. Where a brand publishes no air delivery figure we say so on the model rather than estimating one.

Frequently asked questions
Which is the best room air cooler in India?
Among the 8 verified here, the value pick is the Voltas Delite 36 at ₹6,265 with a 36 litre tank. Filter by the floor area you actually need rather than by tank litres — a bigger tank is a longer run time, not a colder room.
What does a room air cooler cost?
On brand-store prices checked in September 2026, 8 models run from ₹6,265 (Voltas Delite 36) to ₹16,200 (Ram Coolers Metal Cool 350 NH). Street prices on Amazon and Flipkart are frequently below these in a sale week.
Does an air cooler work in humid weather?
Not well. An evaporative cooler works by evaporating water into the airstream, so it cools hardest in dry heat and does very little once relative humidity passes about 60%. In coastal cities and through the monsoon it mainly adds moisture. If that describes your summer, an air conditioner or a fan is the better purchase.
Does it need a window open?
Yes, and this is the most common installation mistake in the category. A cooler pushes humid air into the room and that air has to leave. Sealing the room raises humidity until evaporation — and therefore cooling — stops. Keep a window or door open for cross ventilation.
How much electricity does it use?
These models draw 100-100 W. At ₹8 a unit and ten hours a day for 180 days that is about ₹1,440-₹1,440 a season — roughly a tenth of what a 1.5 ton inverter AC costs to run, not "free cooling" as some listings imply.
