Evaporative Air Cooler

Evaporative Air Cooler

An evaporative air cooler cools the room by releasing a spray of water into the air. It’s suitable for use in homes and businesses with a dry climate, where humidity stays below 50%.

Evaporative coolers can cool large areas but require open windows to draw in fresh, dry air for quick evaporation. Many have useful features such as a remote control, varying fan speeds, oscillating louvers and an LCD panel.

Better Air Quality

Evaporative coolers draw fresh air into the home, boosting indoor air quality. They don’t recirculate stale air like traditional HVAC systems do, and they use significantly less electricity to operate.

Air coolers work best in arid environments where water can evaporate quickly. They’re also less effective in humid climates, where high levels of humidity prevent water molecules from separating and floating into the air.

The evaporative cooling process also works as an indoor humidifier, adding moisture to the air that has been dried out by standard AC units. This moisture can help alleviate symptoms of dry air, such as throat irritation and dry eyes.

To avoid the build-up of mildew and bacteria in the honeycomb cooling pads, it’s recommended to run your evaporative cooler in fan-only mode for 15 minutes after use to ensure the pad is dry and not a breeding ground for germs. Additionally, it’s important to regularly clean and disinfect your air conditioner’s water tank and replace the filter, as they can easily become clogged. These regular maintenance tasks are far easier to do with an evaporative cooler than with a traditional HVAC unit.

Better Humidity

An evaporative cooler passes warm air over water-soaked cooling pads to cool it. This increases indoor humidity, which helps in dry climates to keep people comfortable and prevents dust mites and mildew from forming. However, when excessively used in humid Evaporative air cooler climates or if the humidity level is already high, the excess moisture can create a swampy swap effect and cause dampness and mould.

In such cases, you can use an evaporative cooler in conjunction with a dehumidifier to reduce excess moisture while still providing comfort and preventing allergies. Evaporative coolers typically use less electricity than an AC and are also more energy efficient.

To get the most out of your evaporative air cooler, ensure that it is running on fan-only mode for 15 minutes after using it in evaporative cooling mode. This will allow the honeycomb cooling pad to dry out and help prevent mildew. You should also ensure that you have a water tank that is cleaned regularly to avoid mildew and bacteria build-up. Some manufacturers offer a bacteriostatic water treatment that can be added to the tank to keep water clean and fresh for best results.


Unlike air conditioners, which use energy-hungry compressors and refrigerant chemicals, evaporative coolers rely on the natural process of evaporation to cool the air. That means that the water used in an evaporative air cooler can actually help Evaporative air cooler supplier to add moisture to dry indoor air – especially useful in the Southwest, where high temperatures and low humidity can cause health problems like itchy eyes and bloody noses.

Because evaporative coolers don’t use a power-hungry compressor or refrigerant gases, they also require far less electricity to operate than air conditioning units do. For instance, an evaporative cooling system that is running in an occupied room will only use about 1.5 kilowatts per hour.

Because of this low-energy consumption, evaporative cooling can be a cost-effective alternative to air conditioning for arid climates. In addition, evaporative cooling allows doors and windows to remain open without compromising home security. For added convenience, many evaporative cooling systems come with optional filters that remove dust and other pollutants from incoming air. The filtering process reduces the need to drain and clean a cooler often, allowing for minimal maintenance costs.


Evaporative coolers, also known as swamp coolers, provide an effective cooling solution for homes and businesses that don’t have air conditioning systems. These coolers work best in climates where humidity stays below 50%, like the western and southern United States.

The main thing to keep in mind with these coolers is that they require ventilation in order to function. Because they evaporate water into the air, they need a fresh supply of clean, cool air in order to function at peak efficiency. This can help reduce the risk of mold and mildew buildup in your home as well, which is good news for those with asthma or allergies.

Many evaporative cooler models have additional functions that make them useful beyond cooling, including a humidifier, air filter, or remote control. These extra features can make these appliances more convenient to use and can help you get the most out of your investment. For instance, some evaporative coolers have different fan speeds and an oscillating function that you can adjust to suit your space and preferences.

Energy Efficiency

An evaporative air cooler uses less energy than a standard refrigerated air conditioner, as it evaporates rather than compresses and cools the air. It’s also a greener option, as it doesn’t use any refrigerant gases which deplete the earth’s ozone layer and produce greenhouse gases.

Hot air is drawn through the evaporative cooling media, which causes the water on the surface to evaporate. This naturally cools the air, and is blown through the fan, cooling the room.

Unlike conventional air conditioning, which requires tightly sealed windows to work, evaporative cooling works best in dry climates. This is because the lower humidity means that there is more potential for air to absorb water molecules.

The cooler will still work in a humid climate, but the cooling effect may be reduced because of the higher humidity. If this is the case, a dehumidifier can be used in conjunction with an evaporative cooler to achieve the desired results. It is important to remember that the reservoir must be emptied and cleaned regularly to avoid mold & mildew.
