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 indoor space. Taking care of it is important, but challenging. 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 every day. One of the most common ideas is houseplants. In theory, it makes sense that a living thing producing oxygen in your home would help 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 influence 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 found that—in a closed setting—the plants studied reduced toxins.

While research implies plants can have a noteworthy impact on a closed space, there’s one concern when it comes to translating that to your home. 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 frequently and depends a lot on the outdoor air quality around your home.

Beyond that challenge, the elements that plants can impact are fairly limited. According to the American Lung Association, studies have shown that plants can eliminate harmful gases found in homes, like formaldehyde. Sadly, gases aren’t the only pollutants in your home hurting 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 likely won’t 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 making their way around your home, start 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 looks 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 make sure your system is clean.
  • Contemplate 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. That’s one-thousandth of a millimeter. The experts at Local HVAC Repair & Service 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 huge difference in your air quality, there’s no harm in keeping them around.
