Do Houseplants Improve Air Quality in Your Home?

The air quality in your home impacts a lot—your comfort, allergies and even the aromas in your home. Taking care of it is important, but difficult. In fact, studies have shown that indoor air pollution can be even harsher than outdoor air pollution. Knowing that, it only makes sense that homeowners continue to research ways to purify the air they breathe each day. One of the most common thoughts is houseplants. In theory, it makes sense that a living thing producing oxygen in your home would positively impact 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 influence 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 see the impact houseplants had on toxins in the air. Again, it was established that—in a closed setting—the plants studied removed 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 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 regularly and depends greatly on the outdoor air quality near your home.

Outside of that challenge, the elements that plants can impact are somewhat limited. According to the American Lung Association, studies have shown that plants can remove harmful gases found in homes, like formaldehyde. However, 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 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 making their way around your home, kick it off with your HVAC system. Sustaining a clean system is one of the greatest ways to keep your air clean. Check your air filter regularly and change it when it appears dirty. Catching particles with your air filter is your first and easiest defense against poor air quality. Arrange annual maintenance to have a professional check out your system. In addition to regular tune-ups, they’ll make sure your system is clean.
  • Contemplate 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’s one-thousandth of a millimeter. The pros at Smyth Air Conditioning 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.
