Do Houseplants Improve Air Quality in Your Home?

The air quality in your home effects a lot—your comfort, allergies and even the smells in your indoor space. Taking care of it is important, but challenging. In fact, studies have shown that indoor air pollution can be even worse than outdoor air pollution. Knowing that, it only makes sense that homeowners continue to search for ways to purify the air they breathe every day. One of the most common ideas is houseplants. In theory, it makes sense that a living thing producing oxygen in your home would improve air quality. But does it make a difference?

What’s the Real Impact of Houseplants on Air Quality?

In the 1980s, scientists at NASA assessed the impact common houseplants had on air quality in a closed chamber. Within that closed chamber, they realized the plants had a positive effect on air quality. In 2009, further research was completed by the University of Georgia to see the impact houseplants had on toxins in the air. Again, it was established that—in a closed setting—the plants studied eliminated toxins.

While research implies plants can have a noteworthy impact on a closed space, there’s one issue when it comes to translating that to your home. Your home is not a closed research area. So, it’s tough to say what—if any impact—houseplants have on your home’s air quality. According to Time Magazine, the air in your home changes often and depends greatly on the outdoor air quality around your home.

Beyond that challenge, the elements that plants can impact are fairly limited. According to the American Lung Association, studies have shown that plants can eliminate harmful gases found in homes, like formaldehyde. Unfortunately, gases aren’t the only pollutants in your home harming your air quality. Particles like pet hair, dust, mold or pollen are also moving around your home—and there isn’t much plants can do about those.

Other Solutions

While houseplants likely won’t fix all the indoor air quality issues in your house, there are HVAC-centered solutions that can help.

  • Keep Your System Clean. If you want to keep pollutants from circulating around your home, begin with your HVAC system. Keeping a clean system is one of the smartest ways to keep your air clean. Check your air filter often and change it when it appears dirty. Stopping particles with your air filter is your first and simplest defense against poor air quality. Book annual maintenance to have a technician check out your system. In addition to regular tune-ups, they’ll ensure your system is clean.
  • Contemplate an Air Purifier. If you want to capture even the smallest pollutants in your space, consider an air purifier. Select models can capture allergens and bacteria as small as .01 micron. That’s one-thousandth of a millimeter. The pros at Central Air Inc can help you find a system that works for your home.
  • Try a Humidifier. The humidity in your home also impacts your air quality. Make sure your home stays comfortable and as irritant-free as possible by keeping a humidity level between 30 and 50 percent. You can select from portable or whole home humidifiers to help.

While houseplants can’t make a huge difference in your air quality, there’s no harm in keeping them around. If you’re ready to increase the quality of the air in your home, Central Air Inc can help.
