Do Houseplants Improve Air Quality in Your Home?

The air quality in your home effects a lot—your comfort, allergies and even the odors in your home. Taking care of it is important, but difficult. In fact, studies have indicated that indoor air pollution can be even higher than outdoor air pollution. Knowing that, it only makes sense that homeowners continue to search for ways to purify the air they breathe all the time. One of the most common thoughts is houseplants. In theory, it makes sense that a living thing producing oxygen in your home would improve air quality. But does it work in practice?

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

In the 1980s, scientists at NASA reviewed the affect common houseplants had on air quality in a closed chamber. Within that closed chamber, they discovered 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 found that—in a closed setting—the plants studied eliminated toxins.

While research suggests plants can have a significant impact on a closed space, there’s one concern when it comes to translating that to your house. Your home is not a closed research space. So, it’s difficult to say what—if any impact—houseplants have on your home’s air quality. According to Time Magazine, the air in your home changes frequently and depends heavily 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 get rid of harmful gases found in homes, like formaldehyde. However, gases aren’t the only pollutants in your home harming your air quality. Particles like pet hair, dust, mold or pollen are also floating around your home—and this isn’t anything plants can do about those.

Other Solutions

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

  • Keep Your System Clean. If you want to keep pollutants from circulating around your home, start with your HVAC system. Keeping a clean system is one of the best ways to keep your air clean. Check your air filter frequently and change it when it appears dirty. Stopping particles with your air filter is your first and easiest defense against poor air quality. Schedule annual maintenance to have an expert check out your system. In addition to regular tune-ups, they’ll make sure your system is clean.
  • Consider an Air Purifier. If you want to capture even the smallest pollutants in your home, 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 Farnell Mechanical, 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 maintaining 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 large difference in your air quality, there’s no harm in keeping them around.
