Indoor air quality affects health and comfort, and certain houseplants have been shown to help filter and improve air by removing toxins and airborne microbes. The concept of plants improving indoor air quality gained prominence after a 1989 NASA study that demonstrated certain plants could remove VOCs and toxins in sealed environments. Recent research continues to support this, such as a 2024 study showing Sansevieria trifasciata and Spathiphyllum floribundum as strong absorbers of benzene pollution indoors (Nature Communications, 2024). Another review highlights plants’ ability to reduce airborne microbes by up to 50%, enhancing indoor environmental health (PMC, 2021).The combination of aesthetic, psychological, and moderate air-purifying benefits makes these plants excellent choices for indoor environments. Based on scientific research and expert recommendations, here are five of the best plants known for their air-purifying abilities:
1. Spider Plant (Chlorophytum comosum)
Spider plants are highly effective at removing common indoor pollutants such as formaldehyde, xylene, and toluene. They are easy to grow and thrive in indirect sunlight with minimal care. Research cites spider plants for their ability to reduce volatile organic compounds (VOCs) in indoor air.
2. Snake Plant (Sansevieria trifasciata)
Snake plants stand out for their resilience and efficiency in absorbing toxins like formaldehyde, benzene, and nitrogen oxides. They release oxygen at night, making them excellent for bedrooms. Studies show that snake plants rank high in purification capacity per unit leaf area.
3. Peace Lily (Spathiphyllum)
Peace lilies can remove air toxins including benzene, formaldehyde, trichloroethylene, xylene, and ammonia. Their glossy leaves and white blooms also add aesthetic appeal while improving air quality. Scientific findings underscore their high capacity for toxin absorption.
4. Aloe Vera (Aloe barbadensis)
Beyond its medicinal uses, Aloe vera is recognized for its air-purifying qualities, particularly its ability to reduce benzene and formaldehyde levels. Aloe is also easy to care for, requiring bright light and minimal water.
5. English Ivy (Hedera helix)
English ivy is noted for reducing airborne mold and fecal particles, making it helpful in allergy relief and improving air quality. English Ivy is a charming and adaptable houseplant, known for its elegant trailing vines and classic green leaves. It’s a favorite for indoor gardens because it is relatively easy to care for and can thrive in a variety of home environments.
