Do Houseplants Improve Air Quality in Your Home?

May 28, 2019

The air quality in your home impacts a lot—your comfort, allergies and even the smells in your home. 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 every day. One of the most common solution 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 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 look at the impact houseplants had on toxins in the air. Again, it was discovered that—in a closed setting—the plants studied reduced toxins.

While research suggests plants can have a substantial impact on a closed space, there’s one problem 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 a lot on the outdoor air quality near your home.

In addition to that challenge, the factors that plants can impact are fairly 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 hovering around your home—and there’s nothing 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 making their way around your home, kick it off with your HVAC system. Maintaining a clean system is one of the smartest ways to keep your air clean. Check your air filter regularly and change it when it looks dirty. Stopping particles with your air filter is your first and best defense against poor air quality. Arrange annual maintenance to have a technician 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. Some models can capture allergens and bacteria as small as .01 micron. That’s one-thousandth of a millimeter. The experts at B & G HVAC can help you choose 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 choose 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. If you’re ready to enhance the quality of the air in your home, B & G HVAC can help.
