What is an Air Cooler?  

Honeywell Portable 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 cool, comfortable breeze through the natural process of water evaporation.  

How do I choose the right air cooler for my space?  

There are three main categories of air coolers:   

• 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 airflow 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 by looking at the CFM (Cubic Feet per Minute) or m3/hour rating of the air cooler. The higher an air cooler’s CFM 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.    

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 two 100W light bulbs. *Running an air cooler requires significantly less electricity than running an air conditioning unit, making them an attractive cooling solution in cities where electricity costs are high.  

How do evaporative air coolers work?  

When warm air is drawn into an 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.  

Are air coolers effective in humid environments?  

Portable Evaporative Air Coolers are more effective in environments with a maximum relative humidity level of 60% or less. Warm, dry air is important for more effective evaporative air cooling, and the temperature decrease will be greater in drier environments because evaporation occurs more when the humidity is low. Evaporative air coolers produce moisture and can be used to increase humidification in a room.   

If you live in a humid location, a portable evaporative air cooler for a home can still be a welcomed, energy-saving cooling option 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 AC.   

How is a portable 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 ACs less environmentally friendly. The more complex composition of air conditioners also makes them more expensive to purchase, and they consume significantly more electricity during use.  

How loud are air coolers?  

Most Honeywell Air Coolers max out at 60 dBA on their highest fan speed setting – the sound level of conversational speech in a quiet room. Smaller spot coolers operating on low-speed offer almost whisper-quiet sound for use during the night.  

By how many degrees will an air cooler decrease air temperature?  

Water air coolers operate by fanning warm air through a wet irrigation pad and blowing out cooler, more moist air. Because it is a natural process, the efficacy of an evaporative air cooler is highly dependent on the heat and humidity of its environment. The drier the climate is – with a relative humidity of not more than 60% – and the hotter the climate is, the greater the cooling action. In ideal conditions in highly hot and arid climates, evaporative air cooling can drop temperatures by 15°F. In more typical conditions, you can expect a moderate drop in temperatures, enough to take off the edge off acute heat.  

Are air coolers energy efficient?  

Yes. Portable air coolers do not contain complex machinery, so they consume very little energy. For example, Honeywell Air Cooler models consume from as low as 32 watts to 300 watts at their highest fan speed, depending on the size and CFM of the unit. At low speeds, some models consume as low as 7.4 watts.  

Can I use a portable air cooler for a room without a window?  

Evaporative air-cooling works by drawing in hot, dry air and fanning out cooler, more moist air. After a while, though, your room will need ventilation or a cross-breeze to circulate the more humid air out of the room and restart the process with fresh, dry air. It is recommended to keep a window and/or door open for adequate cross–ventilation. In large rooms, the cooler doesn’t necessarily need air from outdoors, but it does need some type of airflow to keep the cooling action moving, so keeping doors open to other areas will be needed.

How large of an area will it cool?  

The cooler’s CFM is the key indicator of its cooling capacity. A Portable Air Cooler with a CFM of 200, for example, is a spot cooler and can affect a radius of about 50 sq. ft. A cooler with a CFM of 2,000 can cool a space that is about 500 sq. ft. Bear in mind, though, that evaporative air cooling is also highly dependent on the heat and humidity of the environment for appreciable cooling.  

Are air coolers used indoors or outdoors?  

Honeywell Evaporative Air Coolers are available in a wide range of models for different environments, with models available for indoors and/or outdoors. Portable air cooler outdoor use are constructed with weather-resistant materials, allowing them to withstand rain, direct sunshine, and UV rays. Many larger outdoor models are also equipped with a continuous water connection, allowing you to connect your garden hose for automatic tank refills and extended operation. Indoor models can be used in all indoor living areas as well as enclosed outdoor areas, such as covered patios.
