Evaporative Air Cooler FAQs

How is an air cooler different from an air conditioner?

Air conditioners require a chemical refrigerant and an energy-consuming compressor to transform hot air into cool air. The hot air must be released outside the room, making them less environmentally friendly. The more complex composition of air conditioners also make them more expensive to purchase and they consume significantly more electricity during use.

How can I improve the performance of my Air Cooler?
  • Ensure adequate cross ventilation
  • Evaporative Air Coolers should not be used in enclosed spaces. Doors and windows should be opened to allow free air flow. An Air Cooler works best when placed near an open window, drawing outside air and circulating it in the room before exiting via a window or door. The maximum cooling effect is felt when a person is near the flow of air coming out of the Air Cooler.
  • Check the humidity of your room
  • Evaporative Air Coolers are more effective in environments with maximum relative humidity of 60% or less. If you live in a humid location, air coolers can still be a welcomed, energy saving cooling mechanism for your home by scheduling the air cooler to switch on at specific, drier times during the day. For example, during the hottest hours of the afternoon. Honeywell Air Coolers can also be paired with your air conditioner to extend air conditioner cooling so you can save energy by switching off the air conditioner and extending the cooling effect by switching on a Honeywell Air Cooler
How do I choose the right Air Cooler for my space?

Spot coolers are more compact air coolers that are designed to cool the immediate area around the cooler.
Room coolers are larger in size and provide more powerful air flow ideal for cooling larger spaces such as living or dining rooms.
Outdoor coolers are UV & weather resistant with large water tanks and ultra-powerful airflow, making them ideal for cooling outdoor areas such as your patio or backyard.

Find out the airflow of your air cooler
Look at the CFM (Cubic Feet per Minute) or m3/hour rating of the air cooler. These tell you the amount of air that passes through the air cooler per minute (or hour). The higher an air cooler’s CFM or m2/hour rating, the faster it moves the air, providing wider coverage for the space you want to cool.

The water tank capacity does not necessarily dictate the cooling performance of the air cooler however, it affects the time you need to refill the tank and the physical size of the cooler. Smaller water tanks may physically fit better in smaller rooms. Some room coolers and outdoor coolers have a built-in continuous-water supply connection that allows you to connect with your home’s water hose for continuous tank refills. You can find a simple guide below for choosing an air cooler based on tank size:

What is an evaporative air cooler?

Honeywell Evaporative Air Coolers are an environmentally-friendly and cost-friendly cooling option for your home or office. Much like a breeze flowing across a lake or the refreshing cool air you feel near a waterfall, air coolers produce a comfortable, cool breeze with the natural process of water evaporation.

How do air coolers work?

When warm air is drawn into a Honeywell Air Cooler, it passes through a wet Honeycomb Cooling Media. As it passes through it mixes with the water held in the Honeycomb, causing the water to evaporate and lose heat, resulting in cooler, moisturized air. A powerful fan then propels the cool air into the room (or outdoor area, if outdoors). The result is a constant flow of fresh, moisturized, cool air while old and stale air is circulated out of the room.

Why does evaporation cause lower temperature?

The temperature of dry air can drop significantly when liquid water transforms to water vapor (through evaporation).The process of evaporation happens all the time. Our bodies, for example, perspire in hot weather through evaporation – the sweat dries and drops our body temperature.

How is an air cooler different from a standard fan?

Normal fans use fan blades to circulate air around the room without offering any cooling. Air coolers use the natural process of water evaporation to cool incoming hot air and use a powerful fan to evenly distribute newly cooled air. The temperature of dry air can drop significantly when liquid water transforms to water vapor (through evaporation).

How is an air cooler different from a mist fan?

Mist fans are mainly for outdoor use, unless you want your fan to give you a surprise shower in your living room. It also has to be very hot and very dry for the water to evaporate completely without making a puddle on the ground around the mist fan base. Mist fans also need a constant water connection. There’s no tank, so you can only use them if you have a water connection nearby where you intend to use the fan.

What is Honeycomb cooling media and how does it help in cooling the air?

Honeywell Air Coolers use a unique Honeycomb Cooling Media. The cooling efficiency is much higher than other cooling media due to greater surface area for transfer of humidity to the passing air.

Do Air Coolers require a lot of electricity to run?

Honeywell Air Coolers consume very little electricity. The average power consumption of a Honeywell air cooler is equivalent to running two100W light bulbs*. Running an air cooler requires significantly less electricity than running an air conditioning unit, making them an attractive cooling medium in cities where electricity cost is high.
*Honeywell Room Air Cooler average power consumption 193W.
