Evaporative air coolers use a fan to draw air through an absorbent pad or membrane. The pads or membranes then release water into the air, which cools the air.
But this evaporative cooling also releases a lot of humidity into the room. This is especially true if you live in a humid climate.
1. Load It With Ice
Adding ice to your cooler can greatly reduce humidity, especially if you don’t have an air conditioning unit. It’s important to be aware of how much ice you need to add because too much ice can hamper evaporation.
One of the most effective ways to reduce humidity is to keep your cooler out of direct sunlight and in the shade when possible. This can help ice last longer, and it also helps to reflect sunlight away from the inside of the cooler.
It’s also important to organize your cooler to allow the air to flow properly. This means not putting too much ice in the bottom and not allowing it to sit in the middle or on top of the cooler, where air pockets can cause ice to melt faster.
Instead, try packing your cooler logically, starting with heavier items (like beer and hard seltzer) in one corner of the cooler and finishing with lighter drinks like water bottles or sodas in the other.
If you’re bringing food, make sure to pack it separately from the beverages and other perishables in your cooler. You can use a large plastic container to keep food dry and separate from your drinks, but be careful to ensure the container is large enough for everything you want to store in it.
Once you’ve got the right amount of ice, fill your cooler to the top with a layer of ice. This is the best way to maximize your ice and avoid having it sit in the bottom of your cooler, where it can get soggy from airflow.
Then, place a layer of frozen fruit, vegetables, and other perishables over the ice. Be careful not to pack too many heavy items in your cooler, as these can weigh it down and make the ice melt even more quickly.
Finally, if you’re bringing meat and other perishables more likely to get soggy, consider using a cooler basket or another type of container to keep them dry.
2. Keep It Clean
As with any other appliance that uses water, keeping your air cooler clean is necessary to maintain its performance. It is easy to do and doesn’t take much time or effort (as compared to washing up a cup or rinsing out a dishcloth), but it will repay you by keeping the air quality fresh and helping your appliance last longer.
The first thing to do is to make sure that you keep the water reservoir and the absorbent pad clean. These are the main components of an air cooler and are very important in ensuring it works well and keeps you cool.
You should remove them and give them a good wipe over with washing-up liquid (this can be diluted in water) before you screw them back on. You will need to repeat this process every few weeks as they can start to collect dirt and grime, which reduces their effectiveness.
If your air cooler has non-removable air filters on the sides, wash these regularly as well. This is also a simple task, and you can do it using washing-up liquid, as this will not affect the unit’s performance or the life of the evaporative pads.
Another very simple job is draining the water tank and cleaning it well. Just take it out like you would when refilling it and empty it completely before rinsing it out with clean water and a neutral detergent.
This will make it easier to keep the tank clean when you refill it in the future, and it should help your air cooler last longer and work more efficiently. If you are using the unit a lot, you may want to do this more often, but if you don’t, this is an occasional job that will help ensure it performs at its best.
Lastly, you should check the bleeder drain and pads for signs of mold growth. These can be particularly problematic during hot weather, so if you notice any, you should replace them.
It’s also a good idea to clean the fan motor and blower blades once a month, as they can become clogged up with dust and dirt. Using lubricating oil helps prevent this buildup and improves fan efficiency.
3. Add Some Charcoal
Adding some charcoal is one of the best ways to reduce humidity in residential or industrial coolers. Adding this material will help you keep your room dry and improve your overall health by removing unpleasant odors from the air.
The charcoal in your air cooler will absorb a lot of moisture in the air, which can significantly decrease the amount of humidity that the area has. This makes the air more pleasant to breathe, and it can even help you avoid respiratory illnesses.
Using this method is very easy; you only need to buy some charcoal briquettes and place them in a bowl or basket near the air cooler. Then, leave it in the room for a few hours.
It is important to note that this method can only be used in very small areas; otherwise, it could become a fire hazard. Charcoal is highly flammable, so it is important to be careful where you place it in your house.
Another method of reducing humidity in your air cooler is to use activated carbon. Activated carbon is a very effective odor absorber because it has a large surface area to pick up odor-causing molecules.
You can purchase this charcoal from any health food store. However, you should make sure that the charcoal you are buying is a type that is certified organic.
Aside from absorbing odors, activated charcoal also removes smoke and odor-causing bacteria. This is because it can bind to these microorganisms, which makes it more difficult for them to escape.
If you want to try this method, you should buy some charcoal infused with hydrogen peroxide or distilled water. This way, you can be sure that the charcoal is safe to use and will be able to do its job well.
In addition, you should make sure that the charcoal has been soaked for at least 15 minutes to ensure that it is activated. This is very important since activated charcoal has a higher concentration of oxidants than regular charcoal.
4. Install a Dehumidifier
A dehumidifier can help reduce humidity in an air cooler by removing the excess moisture from the air. This will make the air drier and more comfortable, so you can feel more at ease while using your air cooler.
A small or room-sized dehumidifier can be placed in a room that tends to collect more humidity than other rooms, but the best way to remove excess moisture is with a whole-house system. This system will remove the excess moisture from your entire home and dispose of it properly through a drainage system.
Having a whole-house dehumidifier installed in your air cooler can also help reduce your energy costs. Humidity can cause your air conditioner to work harder, which will increase your electricity bill.
However, a properly sized whole-house dehumidifier can significantly reduce your energy use in the summer. An indoor air quality specialist can determine how big a dehumidifier you need and install it into your air conditioning system.
One advantage of a whole-house dehumidifier is that it can be used to replace your AC’s evaporative cooling coil. While this may not seem like an important advantage, it can actually help to keep the air drier in your home and lower your energy costs.
Another advantage is that it can reduce mold spores, which are known to be detrimental to your health. Besides making you uncomfortable, mold can also lead to health problems such as allergies, asthma, and respiratory issues.
You can even prevent this from happening if you have a whole-home dehumidifier installed in your air conditioner. The dehumidifier will eliminate the moisture in your air, reducing mold spores’ growth.
A dehumidifier can be purchased from a variety of stores or online, but you should be sure to get it professionally installed by an HVAC professional. Having an expert install your dehumidifier will ensure that it’s correctly sized and that it fits into your air conditioner’s ductwork properly.
The biggest downside to a stand-alone unit is that it can be expensive and less effective at reducing humidity than a whole-house dehumidifier. In addition, a stand-alone humidifier can be difficult to locate on the first floor and above if you have a crawl space or basement. It is also noisier than a whole-house dehumidifier.
