Do Houseplants Improve Air Quality in Your Home?

The air quality in your home influences a lot—your comfort, allergies and even the odors in your indoor space. 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 find ways to purify the air they breathe all the time. One of the most common solution is houseplants. In theory, it makes sense that a living thing producing oxygen in your home would improve air quality. But does it actually work?

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 found the plants had a positive effect on air quality. In 2009, more research was completed by the University of Georgia to look at the impact houseplants had on toxins in the air. Again, it was discovered 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 problem when it comes to translating that to your residence. Your home is not a closed research room. 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 regularly and depends a lot on the outdoor air quality around your home.

Beyond that challenge, the things that plants can impact are somewhat limited. According to the American Lung Association, studies have shown that plants can eliminate harmful gases found in homes, like formaldehyde. Sadly, gases aren’t the only pollutants in your home affecting 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 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, start with your HVAC system. Keeping a clean system is one of the greatest ways to keep your air clean. Check your air filter often and change it when it looks dirty. Capturing particles with your air filter is your first and best defense against poor air quality. Schedule annual maintenance to have an expert check out your system. In addition to regular tune-ups, they’ll ensure your system is clean.
  • Think About an Air Purifier. If you want to get even the smallest pollutants in your space, consider an air purifier. A few models can capture allergens and bacteria as small as .01 micron. That’s one-thousandth of a millimeter. The experts at Allstar Heating & Air Conditioning can help you find a system that works for your home.
  • Try a Humidifier. The humidity in your home also contributes to 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 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.
