In our modern world, where we spend a significant amount of time indoors, the quality of the air we breathe in our homes is more important than ever. Surprisingly, indoor air can often be more polluted than outdoor air, filled with common pollutants like formaldehyde, benzene, trichloroethylene, and xylene. These can emanate from everyday items such as furniture, paints, and cleaning products. NASA, in its quest to create sustainable living environments in space, has conducted extensive research on air purification, and one plant stands out in their findings: the Snake Plant (Sansevieria).

Why Snake Plants Are Superstars in Air Purification

Exceptional Oxygen Producers

Night-Time Oxygen Production: Unlike most plants, snake plants convert CO2 into oxygen during the night, making them ideal for bedrooms to keep the air fresh 24/7.

Removal of Air Pollutants

Efficient in Absorbing Toxins: Snake plants are remarkably efficient at absorbing airborne toxins, including formaldehyde, nitrogen oxide, benzene, xylene, and trichloroethylene.

Wide Range of Conditions: They thrive in a wide range of environmental conditions, requiring minimal care, which makes them suitable for almost any indoor setting.

Low Maintenance

Water Requirements: They require very little water, reducing the risk of mold and mildew growth associated with over-watering of indoor plants.

Light and Temperature: Snake plants are tolerant of low light and varying temperatures, making them perfect for indoor environments.

Other Plants Known for Their Air Cleaning Abilities

In addition to snake plants, several other indoor plants are recognized for their air-purifying qualities:

  • Spider Plant (Chlorophytum comosum): Excellent at removing carbon monoxide and other toxins, these plants are also non-toxic to pets.
  • Peace Lily (Spathiphyllum): Known for removing benzene, formaldehyde, trichloroethylene, and ammonia from the air. They also bloom with beautiful white flowers.
  • Boston Fern (Nephrolepis exaltata): Great at removing formaldehyde and acting as a natural humidifier.
  • Aloe Vera: Besides its healing properties, aloe vera is effective at removing formaldehyde and benzene.
  • Rubber Plant (Ficus elastica): Known for its toxin-eliminating properties and ability to produce high levels of oxygen.
  • English Ivy (Hedera helix): Excellent at absorbing formaldehyde and reducing airborne fecal particles, making it ideal for bathrooms.
  • Bamboo Palm (Chamaedorea seifrizii): Effective at removing formaldehyde and is also pet-friendly.
  • Philodendron: While efficient in air purification, they are toxic to pets, so they should be kept out of reach.

The Science Behind Indoor Air Quality and the Role of Plants

Understanding the science of indoor air quality is key to appreciating the value plants like snake plants bring to our homes. Indoor air pollutants come from a variety of sources, including:

Building Materials: Carpets, plywood, and paints can emit volatile organic compounds (VOCs) like formaldehyde.

Household Products: Cleaning agents, aerosol sprays, and air fresheners can release chemicals into the air.

Poor Ventilation: Modern energy-efficient homes may lack proper ventilation, leading to a buildup of pollutants.

These pollutants can contribute to health problems known as “Sick Building Syndrome,” which includes symptoms like headaches, dizziness, nausea, and eye, nose, or throat irritation.

How Plants Improve Indoor Air Quality

Plants improve air quality through a process called phytoremediation, where they absorb pollutants through their leaves and roots. In the case of snake plants and others identified by NASA, they convert CO2 into oxygen, remove toxic pollutants, and improve overall air quality.

Humidity Regulation: Plants also help maintain indoor humidity levels, which is important for human health and comfort.

Microbial Activity: The soil in potted plants can host beneficial microbes that also play a role in neutralizing indoor pollutants.

Integrating Plants into Your Home for Maximum Benefit

To make the most of the air-purifying properties of snake plants and other beneficial species, consider the following tips:

Strategic Placement

Bedrooms: Since snake plants release oxygen at night, placing them in bedrooms can improve air quality while you sleep.

Living Areas: High-traffic areas can benefit from the addition of various air-purifying plants, as these spaces often contain more pollutants.

Bathrooms: Plants like Boston ferns and English ivy thrive in humid environments and can help absorb moisture and pollutants.

Plant Care and Maintenance

Watering: Overwatering can lead to mold growth. Water plants as needed, ensuring proper drainage.

Lighting: While snake plants tolerate low light, they thrive in indirect sunlight. Be mindful of each plant’s lighting needs.

Cleaning: Dust on leaves can hinder a plant’s ability to absorb pollutants. Wipe leaves with a damp cloth periodically.

Creating a Healthy Indoor Environment

Diversify Plant Choices: Incorporate a variety of plants for a broader range of air purification.

Avoid Overcrowding: While plants are beneficial, too many in a small space can lead to high humidity and mold growth.

Combine with Other Air-Purifying Methods: Use air purifiers, maintain good ventilation, and reduce the use of VOC-emitting products.

Precautions and Considerations

While adding plants to your home is generally beneficial, there are a few considerations to keep in mind:

  • Allergies: Some people may be allergic to certain plants or to mold that can develop in overwatered pots.
  • Toxicity to Pets: Some plants, like the peace lily and philodendron, are toxic to cats and dogs if ingested.
  • Pest Control: Indoor plants can attract pests. Use natural pest control methods to keep them at bay.


Incorporating plants like the snake plant into your home is a simple and effective way to enhance air quality. Not only do these plants bring a touch of nature indoors, but they also work tirelessly to cleanse the air we breathe. As we continue to find ways to coexist with our modern environment, turning to nature’s solutions, as highlighted by NASA’s research, offers a sustainable and health-conscious approach to living. Remember, while plants significantly improve indoor air quality, they are part of a broader strategy for maintaining a healthy home environment, which includes proper ventilation and regular cleaning.
