Do Houseplants Improve Air Quality in Your Home?

The air quality in your home impacts a lot—your comfort, allergies and even the odors in your home. Taking care of it is important, but hard. In fact, studies have revealed 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 all the time. 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, additional 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 eliminated toxins.

While research indicates 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 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 regularly and depends greatly on the outdoor air quality near your home.

Outside of that challenge, the things 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. Unfortunately, gases aren’t the only pollutants in your home harming 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 floating around your home, kick it off with your HVAC system. Sustaining a clean system is one of the smartest ways to keep your air clean. Check your air filter frequently and change it when it appears dirty. Catching particles with your air filter is your first and best defense against poor air quality. Schedule annual maintenance to have a technician 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 house, 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 Hammack Service Company can help you choose 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 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 significant difference in your air quality, there’s no harm in keeping them around.
