Living in Tampa, Florida, we all know that the summer months can be incredibly hot and humid. The sweltering heat can make it challenging to stay comfortable indoors, and high humidity levels can cause a range of problems, from mold and mildew growth to physical discomfort and health issues. In this blog post, we’ll explore upcoming trends and projects for maintaining ideal indoor humidity in summer and offer practical tips for keeping your home cool and dry.

What is the Ideal Indoor Humidity in Summer?

The ideal indoor humidity in summer is between 40-50%. At this level, the air is neither too dry nor too moist, and it promotes a comfortable living environment. A hygrometer can help you measure your home’s humidity levels and determine whether you need to take action to adjust them.

What Happens If the Humidity Is Too High?

To combat high humidity in summer, it’s essential to understand the concept of absolute humidity, which refers to the amount of water vapor in the air. The higher the absolute humidity, the more moisture content in the air, which can lead to a host of issues in your home. One of the most significant areas affected by high humidity is the crawl space, which can be a breeding ground for mold growth and other harmful bacteria.

To prevent these issues, it’s crucial to invest in a crawl space dehumidifier, which can help regulate the amount of water vapor in the air and reduce the risk of mold growth. Additionally, ensuring proper ventilation and fresh air circulation in your home can also help control humidity levels and prevent moisture buildup.

It’s essential to be aware of the signs of high humidity in your home, including musty odors, condensation on windows or walls, and visible mold growth. By taking steps to manage indoor humidity levels, you can create a comfortable and healthy living environment for you and your family.

Health Effects

High humidity levels can have a negative impact on your health. It can exacerbate existing respiratory conditions like asthma and allergies, making it more challenging to breathe. High humidity can also increase your risk of developing respiratory infections like pneumonia and bronchitis.

Physical Effects at Home

In addition to health issues, high humidity levels can cause physical damage to your home. Moisture can cause wood to rot, paint to peel, and metal to corrode. It can also damage electronics and other household items.

How do dehumidifiers work, and Why are they so effective in reducing humidity levels?

Dehumidifiers work by drawing in warm air from the room and passing it over cold coils. As the warm air cools, the moisture in the air condenses onto the coils and drips into a collection tank or out a drain hose. This process removes excess moisture from the air, helping to regulate the temperature of the air and prevent mold growth and other issues associated with high humidity levels.

When choosing a dehumidifier, it’s essential to consider the size of your space and the amount of moisture you need to remove. A 50-pint portable dehumidifier like the hOmeLabs 4,500 Sq. Ft Energy Star Dehumidifier can remove up to 50 pints of moisture per day, making it an ideal choice for larger areas or spaces with high humidity levels.

Using a dehumidifier is an easy and effective way to maintain ideal indoor humidity levels in summer, and can help keep your home comfortable and healthy. So, whether you’re dealing with excess moisture in your crawl space or simply want to stay cool and dry during the hottest months of the year, consider investing in a dehumidifier for your home.


Another effective way to reduce humidity levels is by ventilating your home. Use exhaust fans in your kitchen and bathroom to remove excess moisture from the air. You can also open windows and doors to promote air circulation and reduce humidity levels.

Know How to Shower

Showers and baths can contribute significantly to indoor humidity levels. Be mindful of the length and temperature of your showers and use a bathroom fan or open a window to help reduce excess moisture.

Cook Outside

Cooking on the stove and using the oven can also increase indoor humidity levels. Consider grilling outdoors or using a slow cooker or microwave instead of the oven to reduce excess moisture in the air.

Reduce Laundry

Drying clothes indoors can increase indoor humidity levels significantly. Consider using a clothesline outdoors or a dryer vented to the outside to reduce moisture in the air.

Move Plants Outside

Plants release moisture into the air through a process called transpiration. Moving plants outside during the summer months can help reduce indoor humidity levels.
