Do Houseplants Improve Air Quality in Your Home?

The air quality in your home influences a lot—your comfort, allergies and even the smells in your house. Taking care of it is important, but difficult. In fact, studies have shown that indoor air pollution can be even higher 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 reviewed the affect 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, more research was completed by the University of Georgia to determine the impact houseplants had on toxins in the air. Again, it was found that—in a closed setting—the plants studied removed toxins.

While research suggests plants can have a substantial 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 room. So, it’s tough 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 near your home.

Outside of that challenge, the things 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. Unfortunately, gases aren’t the only pollutants in your home hurting your air quality. Particles like pet hair, dust, mold or pollen are also moving 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 space, there are HVAC-centered solutions that can help.

  • Keep Your System Clean. If you want to keep pollutants from circulating 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 regularly and change it when it gets dirty. Stopping particles with your air filter is your first and simplest defense against poor air quality. Schedule annual maintenance to have a professional check out your system. In addition to regular tune-ups, they’ll ensure your system is clean.
  • Contemplate an Air Purifier. If you want to grab even the smallest pollutants in your house, consider an air purifier. Select models can capture allergens and bacteria as small as .01 micron. That is pretty small at one-thousandth of a millimeter. The pros at Stanford Heating & Cooling 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 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.
