The Unseen Consequence of High Humidity:

How Dew Points Affect Your Clothes Dryer

When we think of high humidity and elevated dew points, our minds often drift to sticky skin, curly hair, and uncomfortable sleep. But have you ever considered the impact of these weather conditions on your household appliances? Specifically, your clothes dryer? This blog post will delve into the lesser-known phenomenon of clothes dryer drums condensation into water due to high humidity and dew points.

What is High Humidity?

Humidity refers to the amount of water vapor present in the air. High humidity means the air holds much water vapor, often making the environment feel muggy and uncomfortable. On the other hand, the Dew point is the temperature at which the air becomes saturated and water vapor condenses into liquid. When both humidity and dew points are high, it can lead to various issues, including the one we’re focusing on today: condensation in your clothes dryer.

The Science Behind the Condensation

When the air is saturated with moisture, it seeks more excellent surfaces to condense. Your clothes dryer, which has a metal drum, provides an ideal surface for this condensation, especially when it’s not used. The moisture in the air turns into water droplets, accumulating in the drum and potentially leading to several problems.

Why is This a Problem?

1. Time

As the weather condition that caused the high dew point passes, so shall the moisture buildup in the clothes dryer’s drum.

2. Inefficiency

A wet drum will require more energy to dry your clothes, making your appliance work harder and increasing your electricity bill.

3. Wear and Tear

Constant exposure to moisture can lead to rust and corrosion, reducing the lifespan of your dryer.

4. Mold and Mildew

Water accumulation creates a breeding ground for mold and mildew, which could lead to unpleasant odors and potential health risks.

How to Prevent Dryer Condensation

1. Use a Dehumidifier

Place a dehumidifier near the dryer to reduce the moisture level in the air.

2. Ventilation is Key

Ensure that the area around your dryer is well-ventilated. This helps in circulating air and reducing humidity.

3. Regular Maintenance

Wipe down the drum after each use and keep the lint filter clean to improve airflow.

4. Climate Control

If possible, install your dryer in a climate-controlled area to minimize the effects of high humidity and dew points.


High humidity and elevated dew points are not just a discomfort for humans; they can also wreak havoc on household appliances. Understanding the science behind this phenomenon and taking preventive measures can protect your clothes dryer from the unseen consequences of these weather conditions.


So the next time you find yourself battling the stickiness of a humid day, spare a thought for your hardworking clothes dryer. You can ensure it remains efficient and long-lasting, rain or shine with attention and care.
