Home wellness is more than just calming interiors and restorative sleep practices. Sometimes, you need to get the basics of your living space right, and that includes perfecting the humidity levels within your house.
Sure, it might not be the most glamorous of tasks, but it's extremely important for the well-being of your home, including your bedroom, bathroom, and even living room area. And, the benefits of maintaining a house that's optimally ambient are plenty.
So, you might be wondering what the perfect humidity level is, how it varies through the year, and why it's so important. Well, we have the answers to all of that, so you can consider whether you need to learn how to dehumidify rooms in your home, or they could do with more moisture to reap the health and wellbeing benefits.
What Should the Humidity Be in Your House?
"Keeping indoor humidity between 30% and 50% is more than a comfort goal," says Ken Nelson, indoor air expert at Panasonic North America. "It's a scientific sweet spot endorsed by the EPA and leading IAQ experts."
Within this range, Ken explains that viruses struggle to survive, mold spores stay dormant, and your skin retains enough moisture to stay comfortable. "For sinus health, babies and pets, staying close to the middle (around 40% to 45%) reduces respiratory irritation," he adds. "Plus, it supports the well-being of tiny lungs and furry companions alike."
David Lewis, owner of Misson AC & Plumbing, also finds that indoor humidity levels should fall between 30% and 50%. "That’s where most people feel cozy, and it’s where your home’s materials like wood flooring and furniture stay protected," he says.
"If your humidity regularly creeps above that, you’re going to start noticing things like musty smells, mold, or condensation on windows." Then, you'll have to take measures to learn how to reduce moisture in your apartment. And since prevention is better than cure, this is your sign to fix your humidity levels and keep your home looking and feeling great.
What's the Best Humidity for Each Season?
As the seasons change, so will the optimal humidity levels. And if your city experiences every season in all its glory, then it's especially important to adjust the humidity as the temperatures beyond the walls of your home rise and drop.
Here's what Chrystal Joliffe, indoor air expert at Carrier, recommends to balance comfort, energy efficiency, and interior air quality throughout the year.
Winter: 30% to 40% to prevent condensation and dry air.
Spring: 40% to 50% humidity levels are perfect as temperatures rise.
Summer: 45% to 55% is ideal in order to reduce the risk of mold and mildew.
Fall: 40% to 50% humidity is best as heating begins.
Following these guidelines for indoor humidity will prevent a home that smells musty.
What's the Best Humidity for Houseplants?
The humidity around your indoor garden matters just as much as the levels in your bedroom and bathroom. "Most houseplants are happiest with indoor humidity levels between 40% and 60%," says David.
"Of course, this varies depending on the plant. If you’ve got tropical houseplants, they tend to prefer humidity closer to the high end of that range, while indoor succulents or desert plants are fine with lower humidity — closer to 30% or 40%."
However, David does not recommend raising the humidity throughout the entire house solely for the sake of your plants.
"You’re better off placing a small humidifier nearby or grouping your plants together in a more humid area of the home, like a bathroom with a window," he advises. "That way, you’re not over-humidifying rooms, which can lead to mold or mildew."
Why Is It Important to Maintain Humidity?
David tells me that humidity has a direct impact on your health, your HVAC system, and your home itself. "If the humidity is too high, you create the perfect environment for mold growth, dust mites, and bacteria," he notes.
"In such cases, your AC has to work a lot harder to keep the house comfortable, and you might start to notice damage to wooden furniture, floors, or drywall."
On the other hand, he points out that if it’s too low, you’ll experience dry skin, sinus issues, and even medical implications in some cases. "Not to mention, viruses tend to spread more easily in dry air," he adds.
"Keeping indoor humidity within the right range helps your HVAC system work efficiently and keeps the air you breathe healthier overall."
