Do Houseplants Improve Air Quality in Your Home?

May 28, 2019

The air quality in your home influences a lot—your comfort, allergies and even the odors in your home. Taking care of it is important, but challenging. In fact, studies have shown that indoor air pollution can be even higher than outdoor air pollution. Knowing that, it only makes sense that homeowners continue to find ways to purify the air they breathe each day. One of the most common solution is houseplants. In theory, it makes sense that a living thing producing oxygen in your home would help 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 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, more research was completed by the University of Georgia to determine the impact houseplants had on toxins in the air. Again, it was found that—in a closed setting—the plants studied reduced toxins.

While research indicates plants can have a noteworthy impact on a closed space, there’s one problem when it comes to translating that to your residence. Your home is not a closed research space. So, it’s hard 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 surrounding your home.

Beyond that challenge, the factors 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 hovering 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 house, there are HVAC-centered solutions that can help.

  • Keep Your System Clean. If you want to keep pollutants from circulating around your home, kick it off with your HVAC system. Sustaining 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. Capturing particles with your air filter is your first and best defense against poor air quality. Book annual maintenance to have a professional check out your system. In addition to regular tune-ups, they’ll confirm your system is clean.
  • Think About an Air Purifier. If you want to capture even the smallest pollutants in your space, consider an air purifier. Some models can capture allergens and bacteria as small as .01 micron. That’s one-thousandth of a millimeter. The pros at True Temp Heating & Air Inc can help you select a system that works for your home.
  • Try a Humidifier. The humidity in your home also affects your air quality. Make sure your home stays comfortable and as irritant-free as possible by holding a humidity level between 30 and 50 percent. You can pick from portable or whole home humidifiers to help.

While houseplants can’t make a significant difference in your air quality, there’s no harm in keeping them around.
