Humidity, a frequently overlooked aspect of indoor living, has a subtle but significant impact on how we live our lives. It’s simple to ignore the humidity levels in our surroundings as we go about our daily lives. However, the degree of moisture in the air can significantly impact our well-being, the condition of our homes, and even the lifespan of our belongings.
When the humidity level in your home is high, you feel it. High humidity means that there is a lot of moisture in the air. The air may feel muggy. You may have sweat running down your back or forming on your forehead even when you didn’t do anything strenuous. If you are experiencing this, then it is important to know how to decrease humidity in your home for a number of reasons.
High humidity can be bad for you and your home. For you, it can be uncomfortable and can affect your health. For your home, it can lead to damage through condensation build-up, mold, and mildew.
In this article, we will look at how to decrease humidity to comfortable and safe levels.
Humidity refers to the amount of moisture present in the air. It’s often expressed as a percentage, with higher percentages indicating more moisture. Understanding humidity is important because it affects not only our comfort but also the overall health of our living spaces.
Ideal Humidity Levels
The ideal indoor humidity level can vary depending on factors like climate, season, and personal comfort preferences. However, as a general guideline:
- Winter: Indoor humidity levels between 30% and 40% are typically recommended during the colder months. This helps prevent issues like dry skin and respiratory discomfort.
- Summer: In warmer seasons, indoor humidity levels should ideally be between 40% and 60%. This range provides a balance between comfort and preventing moisture-related problems.
In addition to feeling damp, high humidity can trigger respiratory issues, and allergies, and make it hard to sleep at night.
Therefore, maintaining humidity levels within this range of 30-60% is important.
Impact of Humidity on Health and Comfort
Humidity plays a significant role in how we feel indoors. When humidity is too high, the air can feel heavy and uncomfortable. On the other hand, when it’s too low, it can lead to dry skin, irritated eyes, and respiratory problems.
Excessively high indoor humidity can create an environment where mold and dust mites thrive, potentially triggering allergies and respiratory issues. Conversely, excessively low humidity can cause issues like static electricity, which can damage electronics and create discomfort.
Understanding these basics of humidity is the first step in achieving a healthier and more comfortable indoor environment.
Identifying High Humidity
Recognizing high humidity in your home is crucial for taking corrective action before it leads to more significant problems. While it might seem obvious when the air feels damp, there are specific signs to watch for:
Signs and Symptoms of High Humidity
- Condensation: The most apparent sign is water droplets forming on windows, mirrors, or other surfaces. This occurs when warm, moist air comes into contact with cooler surfaces.
- Mold and Mildew: High humidity fosters the growth of mold and mildew, which often appears as black spots or discoloration on walls, ceilings, or in damp areas like bathrooms and basements.
- Musty Odors: Excess moisture can lead to unpleasant, musty smells in your home. These odors are often a telltale sign of mold or mildew growth.
- Difficulty Breathing: High humidity can make the air feel heavy and difficult to breathe, especially for individuals with respiratory issues like asthma.
Using a Hygrometer to Measure Indoor Humidity
Humidity is typically measured using a device called a hygrometer. This instrument provides a relative humidity reading, which represents the percentage of moisture in the air relative to the maximum amount the air can hold at a given temperature. For example, if the relative humidity is 50%, the air is holding half the moisture it could hold at that temperature.
Place a hygrometer in different areas of your home to get a comprehensive understanding of the moisture levels.
There are several types of hygrometers. For more information on the best indoor hygrometers, click here.
Common Causes of High Humidity
Understanding the causes of high humidity in your home is essential for effective humidity management. Several factors can contribute to elevated indoor humidity levels:
- High Outdoor Humidity: If you live in a humid climate, your indoor humidity levels may rise naturally when it’s hot and humid outside.
- Rain and Storms: Heavy rainfall or storms can introduce moisture into your home through leaks, open windows, or damaged roofs.
- Inadequate Ventilation: A lack of proper ventilation can trap moisture indoors, especially in areas like bathrooms and kitchens.
Water Leaks and Moisture Sources
- Plumbing Leaks: Leaky pipes, faucets, or appliances can introduce excess moisture into your home.
- Damp Basements: Basements are prone to moisture issues, particularly if they’re not properly sealed or if groundwater seepage is a problem.
- Cooking: Boiling water and cooking without proper ventilation can release a significant amount of moisture into the air.
- Showering: Taking hot showers without using exhaust fans can increase humidity levels in bathrooms.
How To Decrease Humidity
There are several ways to reduce indoor humidity. Here are some examples:
Use The A/C
Your air conditioner is one of the perfect tools at your disposal for helping to decrease humidity. It does this by simply introducing cool dry air into your home. While doing this, warm, humid air is removed.
Remember to keep your air conditioner in good working order at all times and check the filter frequently. Clean it when necessary and it should perform well for a long time.
HVAC System Upgrades
Consider upgrading your heating, ventilation, and air conditioning (HVAC) system to include humidity control features. Some modern HVAC systems offer integrated humidifiers and dehumidifiers that can automatically adjust indoor humidity levels.
Use A Dehumidifier
Dehumidifiers are one of the most effective and popular solutions for controlling humidity in your home. They work by drawing in moist air, cooling it to condense the moisture, and then releasing the drier air back into your living space. Here’s an overview of dehumidifiers:
There are many different types of dehumidifiers available in the marketplace. Some small dehumidifiers are portable allowing you to move from room to room or you can have a whole-home unit as part of your furnace.
Types of Dehumidifiers
There are two primary types of dehumidifiers:
- Refrigerative Dehumidifiers: These are the most common type and work similarly to air conditioners. They use a refrigeration process to cool the air, causing moisture to condense and collect in a water reservoir. The dry air is then released back into the room.
- Desiccant Dehumidifiers: Desiccant dehumidifiers use a desiccant material (typically silica gel) to absorb moisture from the air. They’re more efficient in low-temperature conditions, making them suitable for cooler climates or specific applications.
Choosing the Right Size and Capacity
Selecting the right size and capacity for your dehumidifier is crucial for its effectiveness. Consider the following factors when making your choice:
- Room Size: Calculate the square footage of the area you want to dehumidify. Dehumidifiers are rated based on the amount of moisture they can remove in a given time, usually measured in pints per day (PPD). Match the PPD capacity to your room size.
- Humidity Levels: If your area experiences extremely high humidity, you may need a larger-capacity dehumidifier to maintain comfortable levels.
- Usage: Consider how frequently and for how long you intend to run the dehumidifier. For continuous use, a unit with a larger water tank or the ability to connect to a drain may be preferable.
Maintenance and Operation Tips
To ensure your dehumidifier functions optimally and lasts a long time, follow these maintenance and operation tips:
- Regular Cleaning: Clean the water reservoir and other accessible parts of the dehumidifier regularly to prevent mold and bacteria growth.
- Filter Replacement: If your dehumidifier has a filter, replace it as recommended by the manufacturer to maintain airflow and efficiency.
- Placement: Position the dehumidifier in the center of the room for even air circulation. Keep it away from walls and obstructions.
- Emptying the Reservoir: Empty the water reservoir when it’s full to prevent spills and maintain efficiency.
Use Exhaust/Ventilation Fans
Kitchens and bathrooms often have exhaust or ventilation fans. These are specifically meant to be used to remove excess moisture from these areas.
Hot showers or baths, cooking, and washing dishes all contribute to the humidity inside your home. If ventilation is not adequate, exhaust and ventilation fans do a great job of pulling moisture outside of the home.
Humidity-activated exhaust fans are equipped with humidity sensors that automatically activate when they detect elevated moisture levels. They are ideal for spaces like crawl spaces and attics, where humidity issues may not always be apparent.
Hang Your Laundry Outside
Damp clothes fresh out of the washing machine will increase the humidity in your home as they dry. While using indoor drying racks may be a good way to reduce energy costs on your electric dryer, especially during the warmer months, you may be able to hang those clothes on a clothesline outside. This removes the dampness from inside your home and helps to decrease indoor humidity.
Move Houseplants Outside
As beautiful as houseplants are, they can add to the humidity inside a home. Plants are both effective in improving indoor air quality and creating a healthy indoor environment. But the downside is they release some moisture into the air.
If the humidity is already high inside your home, house plants can contribute to that adding to the problem.
Open A Window
Have you noticed that after you have a hot shower if you open the bathroom window the condensation on mirrors and fog within the space disappears? The same idea applies when you find your home too humid, and when the air is dryer outside.
All you have to do is open a window or two to create airflow and that will push the humid air outside of your home replacing it with fresh air.
Seal and Insulate Your Home
Properly sealing and insulating your home can prevent moisture infiltration. Check for gaps and cracks in windows, doors, and walls with weatherstripping and caulking to keep outdoor humidity from affecting indoor levels.
Take Cooler Showers
Speaking of showers…if you are a fan of hot showers, you should be well aware of the steam it creates. By reducing the temperature of your shower by just a few degrees, you will still have a comfortable, warm shower, but you will also reduce the amount of steam produced.
Also, reduce the amount of time that you take a shower to reduce humidity further.
Monitor Your Gutters & Pipes For Leaks
Gutters around the outside of the home are a common source of indoor water leaks. When an indoor water leak is left unnoticed, not only will it cause damage to the structure of your home, but it will increase the humidity level as well.
Condensation, stains on drywall, wet spots, and water bills that are unusually high are all signs of a possible indoor water leak. Any leaks are critical to find and fix ASAP.
Check Floor Rugs
Rugs can add to the humidity inside your home. This is because they are so good at trapping and holding moisture. Sometimes, rugs will develop mold or grow fungus due to the moisture trapped inside of them.
If your rugs smell musty or damp, there is a solution. You can have them dry cleaned or if you prefer, replace your rugs to reduce humidity in the home.
Silica Gel Packets
Silica gel packets are small bags filled with silica gel beads, which are excellent at absorbing moisture. You can place these packets in various moisture-prone areas, such as closets, drawers, and storage containers, to prevent dampness and mildew.
Reusable Dehumidifying Bags
Similar to silica gel packets, reusable dehumidifying bags contain desiccant materials that can be rejuvenated by heating in an oven. These bags are eco-friendly and can be used repeatedly to combat humidity in small spaces.
Put Out Some Charcoal
Believe it or not, charcoal is very effective at absorbing air moisture. All you need is a small bowl or basket where you would place a few charcoal briquettes that you would ordinarily use with your barbeque.
The charcoal will help to lower humidity in your home and will continue to do so for months. You just have to replace the briquettes every three months to keep them fresh.
