do evaporative coolers work in high humidity

If you’re wondering, “Do evaporative coolers work in high humidity?” then the answer is yes.

The quality of the air inside your home or office can have a huge impact on your health. 

Unfortunately, conventional air conditioners don’t perform so well when the humidity is high.

And that is why I explain how they work in this article and share some top tips on getting the most out of them.

Evaporative coolers work in high humidity, but with some limitations. If you live in a hot and humid climate, it can be a great way to lower the temperature in your home without using electricity or air conditioning. 

Why Should I Reduce My Room’s Humidity?

why reduce humidity

The answer is simple: because it’s better for your health.

You might think that the humidity in your room is a non-issue, but it can actually be a major problem.

Reason #1: It Helps Keep Your Skin & Mucus Membranes Moist

If you’re not sure what humidity is, it’s the amount of water vapor in the air (and if you’re wondering why that’s important, it helps keep your skin and mucus membranes moist). 

But when humidity levels are too high, they can lead to mold and mildew growth on the walls of your house.

And those are things that spread easily and can cause serious health problems

Reason #2: It Can Lead To Respiratory Disorders

The human body needs moisture to survive, but too much of it can cause problems, according to the American Lung Association.

Living in an area with high levels of indoor air pollution (which can also be caused by mold growth) can lead to respiratory disorders like asthma and chronic obstructive pulmonary disease (COPD). 

So if you’re living in an area where there are high levels of outdoor air pollution, or if you’ve got some kind of lung condition already, reducing your room’s humidity should be a priority.

Reason #3: It Can Cause Your Furniture & Floors To Become Damaged

if you live in the tropics, you probably know that humid weather can make it tough to sleep and even worse if your bedroom is hot and sticky at night!

In addition, when your home’s humidity is too high, it can cause your furniture and floors to become damaged.

In particular, wood floors can develop cracks and warps if their moisture content increases too much.

What Do I Need To Reduce High Humidity?

High humidity is the enemy of your home. It can cause walls and floors to dry out, causing them to crack and weaken.

It makes it hard for mold to grow, which means that when you do get a mold problem, it will be much more difficult to get rid of.

It can also cause damage to furniture and other furnishings by attracting moisture from the air around it.

Here are some tips to reduce high humidity:

Tip #1: Open Up Your Windows And Doors

The first thing you should do is open up your windows and doors as much as possible.

If you have a lot of windows in your house, consider getting different types of curtains that will allow more light than just plain white ones. 

Tip #2: Install Window Blinds If There’s Too Much Light

If you’re too concerned about letting in too much light, consider installing blinds that block out most of the sun’s rays while allowing in enough. 

This is so that there’s still some natural light coming through them at night time without making it too dark inside where people need to sleep or work.

It’s also important during the daytime hours when they’re home alone without their children around them.

Tip #3: Seal Your Home

Make sure your home is well sealed.

If you have gaps in your insulation, it’s going to let moisture into the air and make it more humid.

Make sure there are no leaks in your ceiling or walls, this will increase moisture in the air. 

Tip #4: Check For Mold And Mildew

Check for mold and mildew around electrical outlets and other places where water might get trapped.

Lastly, keep vents open that lead outside so that cold air can enter your home and help keep things cool.

The problem is that it can be hard to measure humidity without getting into the nitty-gritty details of science. 

Tip #5: Get Rid Of Any Plants 

Plants release moisture into the air and will increase your humidity by releasing water into the environment.

So if you’re trying to keep your home or workspace dry, don’t keep any plants!

If you do want to keep some plants around, there are some tricks you can use to reduce their moisture output. 

For example, there’s an easy way to keep cut flowers fresh for weeks on end

Put them in an airtight container like a mason jar (don’t worry, it won’t ruin their color!).

This helps keep moisture from getting in as well as keeping out pests like ants 

Tip: Another option is investing in an electric humidifier that emits.

How Much Does An Evaporative Cooler Lower The Temperature?

The answer is, it depends. Here’s the thing: you can’t really measure the temperature in a room with an evaporative cooler. 

That would be like measuring the temperature of a room and then comparing it to a thermometer reading.

Imagine yourself saying something like, “I’m sure my thermometer says this is hotter.” after the measurement.

You might be able to get something close, though, say, 10 degrees Fahrenheit lower. But that doesn’t mean it’s 10 degrees warmer, just a more comfortable temperature. 

But that doesn’t mean it’s not still cold enough for you to need heat! You might be able to tell if your house feels warmer or colder than usual.

But that doesn’t necessarily mean that your air conditioner is working well enough to cool down your house.

And remember, even at that, your evaporative cooler mightn’t still be working well enough to cool down your house.

There are other things you can do to help keep cool and comfortable in the summertime.

Tip: You can still keep cool by turning up the thermostat.

So, Do Evaporative Coolers Work In High Humidity?

Evaporative coolers are a great way to beat the heat when temperatures soar. But do evaporative air coolers work in high humidity?

The answer is yes, evaporative coolers work in high humidity, but with some limitations.

If you live in a hot and humid climate, then an evaporative cooler can be a great way to lower the temperature in your home.

It will comfortably do this without using electricity or air conditioning.

Evaporative coolers are not a replacement for conventional air conditioners, but they can help you keep your home at a more comfortable temperature.

And while at it, you wouldn’t have to rely on expensive energy bills.

How Does An Evaporative Cooler Work?

how evaporative coolers work

An evaporative cooler works by first drawing in warm air from outside your house. And then, it runs that air through a wet pad that contains water and mineral salts. 

The water evaporates into steam, which reduces the temperature of the air before it’s returned to your home.

In addition to cooling the air, evaporative coolers also remove moisture from it, which helps reduce indoor humidity levels.

Evaporative coolers work in high humidity because they use the air in the room to cool it down. 

The air is drawn into the evaporative cooler and passes through a pad that is moistened with water.

The water evaporates, taking heat with it. This causes the air to lose heat and become cooler. 

The amount of cooling depends on several factors: 

Factor #1: Air Flow

air flow factor

An evaporative cooler works by allowing air to flow through it. The air is brought in from outside and circulated through a fan.

Water is then added to the air, which evaporates when exposed to heat. The water flows out of the cooler, where it can be reused.

Air flow is important for the evaporative cooler. It needs to move enough air to keep temperatures low but not too much that condensation occurs in the unit itself. 

If it is too warm inside the unit, then condensation will occur on surfaces inside the unit and make them wet and slippery.

The more air that flows through the pad, the faster it will cool down. 

Factor #2: Positioning 

If you place your outdoor unit near an open window or door, you will get more airflow than if you place it away from any openings. 

What if one lives in an area where there are no windows or doors on the outside wall of the home?

Such a person will then want to place your outdoor unit against that wall. 

Factor #3: Humidity Levels

level of humidity

The higher the humidity level is outside, the more cooling capacity your system will have.

This is because there will be more moisture in the air for the pad to absorb and convert into coolness for your home or business.

If you live in an area where it is very humid outside, then you will want to make sure that your unit has a dehumidifier installed. 

The dehumidifier will remove moisture from the air as it passes through the cooling pad and then that moisture onto drain pipes or a holding tank.


With everything said, “do evaporative coolers work in high humidity?” The short answer is; Yes!

People who are looking for alternatives to air conditioning in highly humid environments should consider evaporative coolers, especially if they live in a hot, dry region. 

Although these units don’t work as well at low humidity or high humidity, when the air is cool and dry, results can be dramatic.

Evaporative coolers provide great circulating air and make the room feel much cooler.

However, People considering evaporative coolers should know the downsides. Fans are noisy and more expensive than air conditioners.
