Breathe Easy: How House Plants Combat Mold and Improve Indoor Air Quality

🚀Living on the Space Coast, we are privy to the latest advancements in space exploration and research because we are surrounded by the companies and scientists making it happen.🌴

In 1989 NASA performed an experiment to see which house plants best filter the air. Specifically to see which would be most beneficial for long term space travel. 

The air in our homes can become up to 30% more polluted than air outside from over recycling. That is a scary thought when you see the amount of time we spend inside our homes. Many species of indoor plants can actually help absorb mold and spores. Studies have shown that rooms with air-filtering houseplants can improve this air quality by 60%. It is highly recommended to keep one good sized house plant per 100 square feet to help clean polluted or dirt-filled air. 

Plant leaves are a filtration device, and the bigger the leaves the more air the plant is able to filter. Please note it is also important that plants are kept clean and not overwatered in order not to be a source of mold. 

Although houseplants do not prevent all mold from forming in your home or office, nor do they reverse serious mold problems, they can be one little step in preventing harmful mold from getting out of hand. If you have a serious mold problem, the first step is getting your home tested. Contact Bio Pro  today and get to the bottom of your mold problem.


Here are some plants that are recommended:

🪴Snake Plant

If you are a known plant-killer then this is the plant for you! Snake plants love drier climates and warm light. They can grow quite tall and are a great plant for a room with windows.

🪴Peace Lily

The top-rated plant for removing bacteria and mold spores from the air, and breaking down and neutralizing toxic gasses. These tropical natives require indirect sunlight and require minimal attention.

🪴Boston Fern

Ferns love to clean air! They thrive in colder environments with a higher humidity level, and need a moist soil to thrive and grow. Easy care with only one good soak per month needed.

🪴Aloe Vera

This is a great plant to keep around if you or your kids often incur small cuts or burns. Inside each leaf is a thick clear gel that carries a lot of healing properties. Aloe Veras love the light and are tough.

🪴Spider Plants

Spider plants are pros at ridding the air of formaldehyde, a carcinogen used to treat wooden furniture. The plants also get rid of xylene, a powerful chemical found in many household cleaning products and detergents. In one test, NASA even found that spider plants removed 95 percent of toxic air from a sealed chamber in 24 hours.


Plant-based air filtration is a natural way to remove mold spores and other pollutants from the air. Certain plants have been shown to be effective at removing mold spores from the air. These plants work by releasing chemicals that trap and deactivate mold spores.

Regular mold inspections are also important for preventing mold growth. Mold can grow in areas where there is moisture, such as behind walls, in crawl spaces, and in attics. By inspecting your home regularly for signs of mold, you can catch any problems early and take steps to prevent them from getting worse.

Combining plant-based air filtration with regular mold inspections can provide a synergistic benefit for preventing mold growth. The plants will help to remove mold spores from the air, while the regular inspections will help to identify any areas where mold may be growing and take steps to prevent it from spreading.

In addition to plant-based air filtration and regular mold inspections, there are a number of other things that you can do to create a healthy living space that encompasses both clean air and mold prevention. These include:

  • Keeping your home well-ventilated
  • Controlling the humidity levels in your home
  • Repairing any leaks or water damage
  • Cleaning regularly

By taking a holistic approach to creating a healthy living space, you can help to protect your family’s health and well-being. If you are concerned about mold in your home, it is important to talk to a qualified professional like Bio Pro. They can help you to assess the situation and develop a plan to prevent mold growth and improve air quality.
