Air Cooler


The air cooling system has a number of distinguishing characteristics that set it apart from other cooling systems. Evaporative air coolers or swamp coolers provide cool air, which use motors and water to do it. Air coolers have a lower operating cost than air conditioners because their motors use very little electricity and water is abundant in our environment. 

They are available in a variety of sizes and, unlike air conditioners, do not require a ventilation system. Air coolers add dampness to the space since they use water to cool it down. An air cooler can reduce the temperature in a room by up to 20 degrees Fahrenheit.

Air Conditioner 

Air conditioners are far more efficient than any other cooling method. To lower the temperature, they mostly use refrigerants and compressors. As a result, an air conditioner consumes significantly more energy than any other cooling method. 

According to estimates, air conditioning accounts for 10 to 18 percent of a household’s energy bill. There are numerous health advantages to using an air conditioner. .

Taking Care of Your Evaporative Air Cooler

Portable evaporative coolers provide effective and fantastic cooling in hot and dry climates, but it’s crucial to follow the maintenance instructions to get the most out of them. 

One of the most important aspects of cleaning an air cooler is to avoid mildew and a musty odor. Here are some cleaning tips for portable evaporative coolers.

Cleaning the Water Tank

If you use a portable air cooler for an extended period of time without changing the water, it may produce unpleasant aromas and may even endanger the users’ health because the water is no longer hygienic.

Sweep the inside of the air cooler with a soft cloth or sponge. It’s possible that some debris will sneak inside. Because it will develop obstructions, the cooler will become inoperable, and unclean water will circulate through it.

Step 4: Fill the water tank with vinegar and soak it.

Fill the tank halfway with water and vinegar, then let the vinegar sit for an hour. You can also use mild soap and warm water to clean the water tank.

Step 5: Scrub the water tank.

Cleaning the Cooling Pad

Cooling pads are critical components in the function of the fan. You should clean the cooling pads once a month to guarantee that the Portable evaporative cooler runs smoothly.

Step 1: Soak the pads in lemon juice or vinegar for a few minutes.

Submerge them for 30-60 seconds in a mixture of water and lemon juice. Cleaning pads with vinegar is just as effective; mix water and vinegar in a 50-50 ratio solution.

Note: Vinegar can be used, but the scent will stick on your cooling pads and be difficult to remove.

Step 2: Use a cooling pad that has been air dried.

After properly soaking the cooling pads, rinse them thoroughly and lay them aside to dry .Because the pads must be entirely dry before being reinserted into the portable evaporative cooler.

Final Verdict

The Hessaire Evaporative Cooler Hessaire MC18M is ideal for anyone who wants to use it both indoors and out, and with up to 5 cooling and fan modes to choose from, you’ll have plenty of options to find the best mode for you.
