Do Houseplants Improve Air Quality in Your Home?

The air quality in your home effects a lot—your comfort, allergies and even the odors in your indoor space. Taking care of it is important, but difficult. In fact, studies have revealed 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 work in practice?

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 realized the plants had a positive effect on air quality. In 2009, more 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 reduced toxins.

While research implies plants can have a substantial impact on a closed space, there’s one problem 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 often and depends greatly on the outdoor air quality near 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 remove 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 there’s nothing 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 floating around your home, begin with your HVAC system. Sustaining a clean system is one of the greatest ways to keep your air clean. Check your air filter regularly and change it when it appears dirty. Stopping particles with your air filter is your first and best defense against poor air quality. Book annual maintenance to have a technician check out your system. In addition to regular tune-ups, they’ll ensure your system is clean.
  • Consider an Air Purifier. If you want to grab 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 is pretty small at one-thousandth of a millimeter. The pros at Contra Costa Heating & AC 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 holding 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.
