Breathe Easy: How Houseplants Become Your Natural Air Purifiers
Tired of stale, stuffy air inside your home? You don't need expensive gadgets to breathe easier. The solution might be simpler—and greener—than you think: houseplants! For years, studies have suggested that certain plants can naturally filter indoor air, removing harmful toxins and improving overall air quality. This article will guide you through the fascinating science behind plant-powered air purification and show you how to create your own fresh, healthy indoor environment, naturally enhancing your living space with greenery.
The Science Behind Plant Air Purification
While the idea of houseplants purifying air may seem like a recent trend, the research dates back to the 1980s. NASA's Clean Air Study is the cornerstone of this belief. The study, conducted in collaboration with the Associated Landscape Contractors of America (ALCA), investigated the potential of houseplants to remove volatile organic compounds (VOCs) from sealed chambers (Wolverton, B. C., et al. 1989). VOCs are chemicals emitted from common household items like paints, furniture, cleaning supplies, and even building materials. Common VOCs include formaldehyde, benzene, xylene, toluene, and trichloroethylene.
The surprising outcome was that plants absorbed these VOCs through their leaves and roots, effectively neutralizing them. Furthermore, the microorganisms in the soil also play a significant role in breaking down these harmful substances. Many follow up studies have confirmed the air-purifying properties of plants, but not all have agreed on the extent to which plants can remove pollutants from the air. The air inside spacecrafts or small enclosed enviornments, such as in NASA's early studies, is very different from a home. In a very well-ventilated home plants do less.
Which Plants are Air-Purifying Powerhouses?
While virtually all plants contribute to oxygen production, some are particularly efficient at removing specific VOCs. Here are some of the top performers, ready to infuse your home with cleaner, healthier air:
- Spider Plant (Chlorophytum comosum): A resilient and easy-to-grow choice, the spider plant is a champ at tackling formaldehyde, xylene, and carbon monoxide. Plus, it produces "spiderettes" (baby plants) that you can easily propagate to expand your green army.
- Snake Plant (Sansevieria trifasciata): Also known as Mother-in-Law's Tongue, the snake plant is another low-maintenance superstar. It converts carbon dioxide into oxygen at night, making it a perfect bedroom companion. It's also effective at removing formaldehyde, benzene, trichloroethylene, xylene, and toluene.
- Golden Pothos (Epipremnum aureum): This trailing vine is both beautiful and beneficial. The golden pothos is known for its ability to remove formaldehyde, xylene, toluene, benzene, and carbon monoxide. It thrives in various conditions and can be easily propagated from cuttings.
- Peace Lily (Spathiphyllum wallisii): With its elegant white blooms, the peace lily adds a touch of serenity to any room. It's effective at filtering formaldehyde, benzene, trichloroethylene, xylene, toluene, and ammonia from the air. Be aware that peace lilies are toxic to pets and should be placed out of their reach.
- English Ivy (Hedera helix): While often grown outdoors, English ivy can also thrive indoors. It's particularly effective at absorbing formaldehyde, benzene, xylene, toluene, and mold allergens. English Ivy might be best in a hanging basket, as it is also toxic to pets and humans
- Aloe Vera (Aloe barbadensis miller): Though not as effective at removing all the VOC's the other plants take care of, aloe vera plant is a medicinal powerhouse, aloe ver can filter formaldehyde and benzene from the air. Place it near a sunny window and enjoy its soothing gel for sunburns and minor skin irritations.
Creating Your Own Indoor Air Purifying Oasis
Now that you know which plants pack the most air-purifying punch, it's time to green up your home! Here's how to get started:
Selecting the Right Plants for Your Space and Lifestyle
Consider the amount of light your rooms receive. Spider plants and golden pothos tolerate low light conditions. Snake plants can thrive in both bright and low light areas. Peace lilies prefer bright, indirect light. Ensure humidity and proper spacing for plants that need it and don't crowd plants together.
Strategic Placement for Maximum Impact
Place plants in areas with high levels of VOCs, such as near printers, new furniture, freshly painted walls, or newly installed carpeting. Living rooms, bedrooms, and home offices are all good candidates. Cluster plants together to increase their collective air-purifying power. Remember to rotate your plants regularly to ensure even light exposure and prevent them from leaning towards the window.
Optimizing Your Plant Care Routine
Proper watering is essential for healthy plants. Water when the top inch of soil feels dry, and avoid overwatering, which can lead to root rot. Use well-draining potting soil to prevent water from pooling at the bottom of the pot. Dust plant leaves regularly with a damp cloth to remove accumulated dust and allow them to efficiently absorb pollutants. Fertilize your plants during the growing season (spring and summer) according to the instructions on the fertilizer package. Too much fertilizer can damage your plants.
Troubleshooting Common Plant Problems
Keep an eye out for signs of pests or diseases, such as yellowing leaves, spots, or webbing. Isolate any affected plants to prevent the spread of problems. Adjust your watering schedule based on the season and humidity levels. Plants need less water during the dormant winter months. Repot your plants when they outgrow their containers, typically every one to two years.
Beyond Plants: Additional Tips for Improving Indoor Air Quality
While houseplants are a fantastic addition to your air-purifying arsenal, they're not a complete solution. Here are other steps you can take to create a healthier indoor environment:
- Ventilate Your Home Regularly: Open windows and doors to allow fresh air to circulate, especially after cleaning or renovations. Even a few minutes of ventilation can make a significant difference.
- Use Natural Cleaning Products: Avoid harsh chemicals in cleaning supplies, opting instead for natural alternatives like vinegar, baking soda, and lemon juice. Many household cleaners contain VOCs that can pollute your indoor air.
- Vacuum and Dust Regularly: Dust and allergens accumulate on surfaces and can trigger allergies and respiratory problems. Vacuum carpets and rugs at least once a week, and dust furniture and other surfaces regularly.
- Control Humidity Levels: High humidity can promote mold growth, which can negatively impact air quality. Use a dehumidifier in damp areas, such as bathrooms and basements.
- Change Air Filters Regularly: Replace the air filters in your furnace and air conditioner according to the manufacturer's recommendations. This will help remove dust, pollen, and other pollutants from the air.
- Consider an Air Purifier: For a more comprehensive approach, consider investing in an air purifier with a HEPA filter. These devices can effectively remove fine particles, allergens, and VOCs from the air.
- Limit the Use of Air Freshening Products and Strongly Scented Candles: Air fresheners and many scented candles can release harmful VOCs into the air rather than cleaning it. If you'd prefer to make your own air freshener, simply put water onto a stove, add a bit of citrus fruit, and allow to gently simmer
Debunking Common Myths about Plant Air Purification
There are some common misconceptions about the power of houseplants in cleaning the air. Some of which are:
- One plant can purify an entire room: While houseplants make a significant difference, you'll likely need several plants to achieve noticeable air purification. A general rule of thumb with research backing it is to have at least one plant per 100 square feet of living space to make a difference.
- Plants are the only solution for indoor air pollution: Houseplants are a valuable tool, but they should be combined with other strategies, such as proper ventilation and natural cleaning products.
- All plants are equally effective at air purification: Some plants are more efficient at removing certain pollutants than others. Research the best options for your specific needs and environment.
Benefits beyond Air Purification
The benefits of houseplants extend far beyond air purification. Studies have shown that indoor plants can improve mood, reduce stress, increase productivity, and enhance creativity. They can also add a touch of natural beauty and tranquility to your home, creating a more peaceful and inviting atmosphere.
Plants Add Moisture in the Winter
Plants release about 97% of the water they take in which can also increase humidity in the room and improve overall indoor air quality as a result. If you are interested in how the humidity in a room affects respiratory health, visit the EPA's website
