The EPA recommends 30 to 60% of indoor humidity. However, depending on various conditions, you may want the indoor humidity at a certain level. In the summertime, you will require a higher humidity level, whereas you will need a lower humidity level during the wintertime.
What Humidity Should My House Be
It doesn’t matter which type of weather you live in. Because the amount of relative humidity in the air inside your home can affect your comfort and the functioning of your air conditioning and heating units, besides comfort, relative humidity in your home can affect your general well-being.
Maintaining an ideal indoor humidity should be your priority as a house owner. If the proper humidity level in the house is not maintained, then your home will feel very uncomfortable to live in. Also, you and others may face chemical reactions or respiratory disorders. Moreover, it can damage both the outside and inside of your home.
Optimum indoor humidity levels might differ depending on your personal preferences, amount of physical activity, clothing, and other conditions. However, according to ASHRAE, you should maintain a range of 45% to 55% humidity.
What is the Ideal Indoor Humidity in the summer?
Summer means warmer temperatures. During this time, mold can form on surfaces in your home. You must not have too low a humidity level in your home. This might cause health issues as well as damage your home. So, it is vital to have a higher indoor humidity level.
The ideal humidity level would be 40 to 60%. This way, you can maintain a reasonably comfortable humidity level without damaging your home or causing health issues.
What is the Ideal Indoor Humidity in the winter?
Usually, cold air is referred to as dry air as it holds less moisture than warm air. During the winter, condensation can form on surfaces in your home, and you must prevent it.
When your home’s warm and moist air comes in contact with cold surfaces, it forms condensation. So you need to have a lower humidity level in your home. Ideally, the indoor humidity should be 30 to 50%.
How Can I Control the Humidity in My House?
You can either actively or passively maintain the humidity in your house. One of the passive control methods would be sealing off the home from external sources of humidity. Or you can actively control the humidity level using humidifiers or dehumidifiers. Also, you can use an exhaust fan and an HVAC system.
Things to Remember
Your home’s humidity level is affected by where you live and standard home functions like steam produced by cooking and showering.
During the winter, you should keep your heating unit’s temperature around 68℉, alongside the recommended humidity level.
You can control and monitor the humidity level all year by installing a humidifier.
High Humidity in the House
Breathing is more manageable with high humidity inside the house. However, high humidity comes with some health risks.
What are the Problems Caused by High Humidity in the House?
There is more chance for mold and bacteria to grow at high humidity. It can aggravate your respiratory problems or allergies. Due to high humidity, your sweat can’t evaporate. So, your body can’t cool itself by sweating.
Moreover, it makes windows and doors stick, wallpaper and paint peel, and wood swell up. Adding to the disadvantages, it creates a breeding environment for insects and other pests.
What Can Cause High Humidity in My House?
The humidity level in your house increases due to two sources-
- Internal Sources
Internal sources include kitchens, bathrooms, even people breathing. A hot shower can form humidity.
- External Sources
Any outside air coming into your home is considered an external source. Poorly maintained HVAC systems, open windows, and doors, cracks around windows and doors can bring humidity into your house.
How Can I Reduce Humidity in My House?
At first, you need to identify the source of humidity. If it’s an internal source (kitchen or bathroom), you can run the exhaust fan. However, if it’s an external source, shut the windows and doors properly. To actively reduce humidity in the air, you can use a dehumidifier.
Low Humidity in the House
Just like high humidity, too low humidity can affect your comfort and health too.
What are the Problems Caused by Low Humidity in the House?
Dry air leads to respiratory and sinus problems. You can be vulnerable to infections, colds, and viruses. More to the disadvantages, dry air can invite bacteria and viruses.
It can cause skin problems like dryness, cracking, and chapped lips. The moisture of your skin is sucked out by dry air, thus cools your body in the process. This can make you feel colder than you are. In this case, if you turn up the heat, it will dry out the air even more!
What Can Cause Low Humidity in My House?
Many factors cause low humidity in your house. The heating system of your home can be one of them. It heats the air inside your home, like a fan, or exhaust system, AC, or environment. It can remove the moisture from the air to some extent. And it creates lower humidity.
Dry, cold air from outside your home can also cause low humidity in your home. Cold air isn’t capable of holding much moisture. So, when the inside air comes in contact with the outside air, it becomes drier.
How Can I Increase Humidity in My House?
You can seal off your home from outside and confirm that no dry air is coming in. Also, you need to ensure that your HVAC system is not bringing in dry air.
You can actively increase the humidity by spraying water around the house using a spray bottle, boiling water on the stove, leaving the bathroom door open while showering. The most efficient way to increase humidity would be using a humidifier.
Q: What exactly is “Relative Humidity?”
Ans: It means the percentage of water present in the air at a specific temperature. Relative humidity of 30% means the air has 30% of moisture in it. During winter, the capacity of air holding moisture decreases, whereas, during summer, it increases.
Q: Is 65% Humidity too high for a House?
Ans: Yes, it is. You should maintain the humidity level at around 30-60%. When it’s above 60%, the air inside the house gets too wet, which is dangerous for both your family and the house. Sometimes, basements, which are below the house can achieve a higher humidity, which can cause real problems for sudden exposer. To solve the problem, it is ideal to use a basement dehumidifier.
Q: Is 40% humidity bad?
40% humidity is between the comfort level which is 30-50%. So, if your house environment has a 40% humidity level, it is not bad, rather it is safe and comfortable for you and your family.
Right humidity level keeps your home warm in the winter and cool in the summer. Moreover, your home HVAC systems work efficiently if you have the proper moisture level in your home. If you have a humidifier, then make sure to maintain the proper humidity level. And if you don’t have a humidifier, you know what to do!
