Looking for a natural way to breathe cleaner air? Mother Nature’s got your back with her lineup of air-purifying superheroes – indoor plants! These green warriors don’t just sit pretty on your windowsill; they’re working overtime to filter out harmful toxins and freshen up your living space.
Best Indoor Plants That Purify Air Naturally
Indoor plants function as living air filters by removing harmful pollutants through their leaves stems roots. These natural purifiers convert carbon dioxide into oxygen while absorbing airborne toxins through their natural filtering processes.
How Indoor Plants Clean the Air
Plants eliminate indoor air pollutants through three primary mechanisms: absorption metabolization transpiration. The leaves absorb toxic compounds like benzene formaldehyde through microscopic pores called stomata. Root-zone microorganisms break down these harmful substances into harmless byproducts. The plant’s transpiration process pulls contaminated air down to the roots where beneficial microbes neutralize pollutants.
| Plant Part | Purification Role |
|---|---|
| Leaves | Absorb toxins via stomata |
| Roots | Host purifying microbes |
| Stems | Transport filtered water |
NASA’s Clean Air Study Findings
NASA’s research identified several indoor plants effective at removing common air pollutants in enclosed spaces. The study demonstrated that specific plants eliminated up to 87% of air toxins within 24 hours. Spider plants removed 95% of formaldehyde while peace lilies eliminated 80% of benzene from test chambers.
| Plant Type | Toxin Removal Rate |
|---|---|
| Spider Plant | 95% formaldehyde |
| Peace Lily | 80% benzene |
| Snake Plant | 75% trichloroethylene |
Top Air-Purifying Plants for Your Home
Indoor air purifying plants actively filter specific toxins while adding natural beauty to living spaces. NASA research confirms these plants excel at removing common household pollutants through their natural filtration processes.
Snake Plant (Sansevieria)
Snake plants rank among the most effective air purifying plants, removing 4 of the 5 main indoor toxins. These hardy succulents convert CO2 to oxygen at night, making them ideal for bedrooms. Research shows one snake plant filters formaldehyde (107 parts per billion), nitrogen dioxide (23 ppb), benzene (78 ppb) within 24 hours in a 100 square foot space. Snake plants thrive in low light conditions between 60-85°F with minimal watering every 2-6 weeks.
| Toxin Removed | Filtration Rate |
|---|---|
| Formaldehyde | 107 ppb/24h |
| Benzene | 78 ppb/24h |
| Nitrogen Dioxide | 23 ppb/24h |
Spider Plant (Chlorophytum Comosum)
Spider plants remove 95% of formaldehyde benzene xylene from indoor spaces within 24 hours. Studies demonstrate these plants absorb carbon monoxide particulate matter through their long striped leaves. A single spider plant purifies air in a 200 square foot area when placed in bright indirect light. These resilient plants propagate easily through their offspring creating additional air purifiers naturally.
| Pollutant | Removal Rate |
|---|---|
| Formaldehyde | 95% in 24h |
| Carbon Monoxide | 90% in 24h |
| Particulate Matter | 85% in 24h |
Peace Lily (Spathiphyllum)
Peace lilies eliminate 80% of benzene trichloroethylene ammonia from indoor environments within 24 hours. Research indicates one peace lily filters air effectively in spaces up to 120 square feet. These tropical plants thrive in medium indirect light between 65-80°F with weekly watering. Peace lilies remove volatile organic compounds through their leaves stems while adding moisture to dry indoor air.
| Compound | Elimination Rate |
|---|---|
| Benzene | 80% in 24h |
| Trichloroethylene | 75% in 24h |
| Ammonia | 73% in 24h |

-
- Set Spider Plants near south-facing windows with filtered light through sheer curtains
-
- Arrange Bamboo Palms 4-6 feet from windows for bright indirect light
Room-Specific Placement
-
- Bedroom: Snake Plants near the headboard purify air during sleep cycles
-
- Living Room: Peace Lilies near electronics neutralize electromagnetic radiation
-
- Kitchen: Spider Plants above cabinets absorb cooking fumes
-
- Bathroom: Boston Ferns thrive in humidity while filtering air
-
- Home Office: Bamboo Palms beside printers reduce chemical emissions
Height & Spacing Guidelines
-
