Do Houseplants Improve Air Quality in Your Home?

The air quality in your home impacts a lot—your comfort, allergies and even the odors in your house. Taking care of it is important, but challenging. 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 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 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 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, further research was completed by the University of Georgia to look at 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 significant 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 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 greatly on the outdoor air quality surrounding your home.

Outside of that challenge, the factors 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. Sadly, 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 there’s nothing plants can do about those.

Other Solutions

While houseplants might not be able to 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 smartest ways to keep your air clean. Check your air filter often and change it when it gets dirty. Catching particles with your air filter is your first and easiest defense against poor air quality. Book annual maintenance to have a technician check out your system. In addition to regular tune-ups, they’ll make sure your system is clean.
  • Think About an Air Purifier. If you want to grab even the smallest pollutants in your house, consider an air purifier. A few models can capture allergens and bacteria as small as .01 micron. That is pretty small at one-thousandth of a millimeter. The experts at US Air Heating and Cooling can help you find 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 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 large difference in your air quality, there’s no harm in keeping them around.
