Frequently asked questions
Is a 45 litre air cooler enough for my room?
The models here are rated by their makers for 170-550 sq ft. Match that to your room rather than to the tank figure — litres tell you refill frequency, not coverage.
What is the price of a 45 litre air cooler?
₹7,590 to ₹17,700 on brand-store prices checked September 2026, across 16 models. The cheapest is the Voltas Wind 54 WW.
How often will I refill a 45 litre cooler?
It depends on humidity and fan speed, not on the tank alone. As a rough guide a cooler evaporates 2-4 litres an hour on high in dry heat, so a full 45 litre tank runs roughly most of a day before it needs topping up.
Honeycomb or wood wool at this size?
14 of these 16 use honeycomb pads. Honeycomb holds more water per unit of airflow, survives hard water better and can be rinsed instead of replaced — worth insisting on at any tank size.
