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 hard. In fact, studies have indicated that indoor air pollution can be even harsher than outdoor air pollution. Knowing that, it only makes sense that homeowners continue to search for ways to purify the air they breathe all the time. One of the most common thoughts is houseplants. In theory, it makes sense that a living thing producing oxygen in your home would help air quality. But does it make a difference?

What’s the Real Impact of Houseplants on Air Quality?

In the 1980s, scientists at NASA studied the impact 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, further research was completed by the University of Georgia to determine the impact houseplants had on toxins in the air. Again, it was established that—in a closed setting—the plants studied reduced toxins.

While research indicates plants can have a substantial impact on a closed space, there’s one issue when it comes to translating that to your residence. 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 regularly and depends a lot on the outdoor air quality surrounding your home.

Beyond that challenge, the elements that plants can impact are slightly limited. According to the American Lung Association, studies have shown that plants can eliminate 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 this isn’t anything plants can do about those.

Other Solutions

While houseplants might not be able to 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, begin with your HVAC system. Keeping a clean system is one of the greatest ways to keep your air clean. Check your air filter frequently and change it when it gets dirty. Catching 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 make sure your system is clean.
  • Think About an Air Purifier. If you want to capture 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 team at Strine's Heating & Air Conditioning 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 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.
