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 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 find 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 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 realized the plants had a positive effect on air quality. In 2009, additional research was completed by the University of Georgia to see the impact houseplants had on toxins in the air. Again, it was discovered 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 concern when it comes to translating that to your house. 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 around your home.

Outside of that challenge, the elements that plants can impact are slightly limited. According to the American Lung Association, studies have shown that plants can remove 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 floating around your home—and there isn’t much 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 floating around your home, begin with your HVAC system. Maintaining 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. Capturing particles with your air filter is your first and simplest defense against poor air quality. Arrange annual maintenance to have an expert check out your system. In addition to regular tune-ups, they’ll confirm your system is clean.
  • Consider an Air Purifier. If you want to capture even the smallest pollutants in your home, consider an air purifier. A few models can capture allergens and bacteria as small as .01 micron. Which is one-thousandth of a millimeter. The experts at Carefree Heating and Cooling, LLC 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 choose from portable or whole home humidifiers to help.
