Did you know that houseplants can help our houses’ indoor air become cleaner? We’ve long known that having indoor plants around us makes us happier and less stressed, but there’s also the added bonus of better air quality! See the top indoor plants for cleansing the air.
We spent a lot of time inside over the winter. Healthy indoor air is unquestionably a high priority. Without adequate ventilation, indoor contaminants quickly accumulate to hazardous levels.
Two main types of indoor pollution exist:
- dust, pollen, and mould spores are examples of particulates.
- vaporised organic substances (VOCs). Paints, textiles, wallpaper, carpeting, plastics, and solvents that are typically found in most homes emit vapours known as VOCs. Harmful gases are released even by common household chemicals including bleach, ammonia, detergents, furniture polish, carpet cleaners, and moth balls.
While mechanical or electrostatic filters are capable of capturing particulates, it is challenging to completely get rid of airborne chemicals until the source is eliminated.
Let’s examine some fundamental botany: All humans and other living things use oxygen to breathe, which is released by plants when carbon dioxide (CO2) is absorbed. That idea is used outside to offset the impacts of air pollution through tree planting. Would house plants have the same effect on the air inside?
A NASA Clean Air Study conducted in 1989 examined the ability of 19 different plant species to purify the air. They discovered that in just 24 hours, the leaves and roots of the plants eliminated up to 87 percent of the formaldehyde, benzene, and trichloroethylene from the air while bringing oxygen back into the space. In conclusion, ordinary low-light houseplants absorbed pollutants and assisted in air purification!
…Or so we believed. According to a 2019 study published in the Journal of Exposure Science & Environmental Epidemiology, the impact of indoor plants on VOC levels has been somewhat exaggerated. Despite the fact that they actually filter the air, the effect they have is minimal because of how slowly they work.
Every little bit helps, we say! Furthermore, the fact that some houseplants filter the air is not unusual.
Indoor Plants That Clean the Air
Some of the top houseplants for cleansing the air include:
1. Spider plants (Chlorophytum comosum) are effective air purifiers that may eliminate formaldehyde, a gas released by cigarette smoke, dry cleaning, artificial carpeting, fingernail polish, and other sources. Additionally, spider plants eliminate carbon monoxide, which might be present in spaces with stoves or fireplaces. Fortunately, growing and caring for spider plants is fairly simple. It will flourish if you just keep it moist in a semi-gloomy to shady area.
2. One of the most common indoor plants, philodendrons, are also effective air filters that eliminate formaldehyde gas. Additionally, they have attractive heart-shaped leaves and fast-growing trailing vines, making them nearly bulletproof plants. If consistently hydrated, they can survive in both full sun and shade. The best philodendrons for cleaning the air are elephant ear, heart-leaf, and Philodendron selloum.
3. Another well-liked, resilient, and simple to cultivate plant is English ivy (Hedera helix). Most contaminants are removed by it. It is not sensitive to light and may live in both sun and shade. Ivy like to be cold and dislikes extreme heat. To prevent spider mites, keep the leaves moist and spray them once a week.
4. The Peace Lily (Spathiphyllum sp. ), a gorgeous plant with a stunning white blossom that does well in typical indoor conditions, is a beautiful example. Alcohols, acetone, trichloroethylene, benzene, and formaldehyde have been found to be removed from the air by peace lilies. Keep moist in a partially shaded area.
5. Distinctive
The snake plant, often known as mother-in-tongue law’s (Sansevieria trivasciata), is relatively simple to produce. Water heavily, let it air dry, and then water again. It can endure any environment, including sun and shade.
Snake plant (this mother-in-tongue, law’s which is 35 years old, genuinely sprang from a mother-in-law).
6. For removing the majority of contaminants, bromeliads receive a gold star. While you sleep at night, they release oxygen and remove air contaminants! The strong, indirect sunshine or fluorescent office lighting is excellent for these attractive plants with their vivid blossoms and lush foliage. This drought-tolerant plant requires little maintenance, but if you overwater it or don’t allow adequate drainage, it will develop root rot.
7. Dracaena prefer a semishaded to shady environment where it can stay moist. The best dracaenas at removing air pollutants are Warneck, Janet Craig, red-edged, and cornstalk.
8. The weeping fig (Ficus benjamina) prefers warm temperatures, high humidity, and bright indirect light. When the soil’s top feels dry, water it, and regularly spritz the top.
9. Rubber plants, or Ficus elastica, survive cool temperatures and little light while purifying the air in any indoor setting.
10. Areca palms (Chrysalidocarpus lutescens), which are attractive and simple plants, purify the indoor air of all contaminants.
More Plants That Clean the Air
- If you prefer floral plants, Chrysanthemums and Gerbera daisies performed well in the testing. They also produced blooms and are efficient at reducing VOCs!
- Aglaonemas, or Chinese evergreens, prefer warm temperatures and moderate to low light levels. Let it dry out a little bit in between waterings. Avoid draughts since they might turn the foliage brown.
- As long as they are kept consistently moist, reed or bamboo palms can survive in low light.
- Aloe vera, bird of paradise, and Boston ferns are a few additional excellent indoor plants that filter the air.
But there’s no need to transform your house into a jungle: Only one or two plants are beneficial per 100 square feet of floor space in a home with 8 to 9 foot high ceilings. Plants should be in 6- to 8-inch wide pots with the soil surface exposed to the air since the roots and microorganisms in the soil play as significant a function as the foliage. The plants analysed don’t appear to be negatively impacted by absorbing pollutants. According to research, the chemicals are securely metabolised by them by being reduced to safe carbon, water, and salts.
Why not clean the air, especially if it is as simple as adding a few extra houseplants, since we clean our homes of filth.
Which houseplant is most effective at purifying the air?
These plants may be suitable for those who want to test their green thumb first. Although they don’t need daily attention, most of them will grow more successfully if they are fertilised once a month.
Spider plants (Chlorophytum comosum)
Spider plants, also referred to as air plants, are quick-growing and look beautiful in hanging baskets, particularly in your workspace. They occasionally even produce beautiful white flowers.
There are more than 200 species of spider plants, and many of them can withstand our occasional carelessness.
Non-toxic: This plant is appropriate for use around children and animals who enjoy playing with swinging objects.
Dracaenas
A novice with a green thumb should grow dracaenas. These numerous indoor plants come in a wide variety of forms, dimensions, and hues. Choose between the rainbow plant, which is a vivid purple colour, or the tall corn plant, which has unique patterning.
Maintain a moist but not saturated soil for the plant because too much water can kill it.
Animal toxicity: If your cat or dog eats dracaenas, they can vomit, salivate more, or get dilated pupils.
Golden pothos (Epipremnum aureum)
This plant, often known as devil’s ivy, may be the closest thing to an indestructible plant there is. It may grow up to 8 feet long and thrives in a range of environments. It is also regarded as one of the best domestic air purifiers for getting rid of typical contaminants.
Water your plants when the soil is dry. In case the plant becomes too large, you can clip the tendrils.
Areca palms (Chrysalidocarpus lutescens)
It’s simpler to grow this tiny Madagascarian plant outside. However, if you have a room with plenty of brilliant filtered light, its gently arching leaves will be a lovely accent.
Plant maintenance: This thirsty plant requires a lot of water throughout its growing phase, but less during the winter.
Non-toxic: Neither cats nor dogs can be harmed by the tall plants or their leaves.
Benzene, carbon monoxide, formaldehyde, trichloroethylene, xylene, and other substances are eliminated.
Chrysanthemums (Chrysanthemum morifolium)
Mums, or florist’s chrysanthemums, are rated as the best air purifiers. They have been demonstrated to remove ammonia as well as common poisons.
Because this flower only blooms for roughly six weeks, reward yourself with a brand-new pot. Alternately, as new growth starts to show in the spring, fertilise the container once more. However, it won’t be able to filter the air without the flowers. You might want to just buy a new pot if you don’t want to wait.
Animal toxicity: Despite having a cute name, mums are poisonous to both cats and dogs.

Want to lessen the pollutants in your house? The most damaging bacteria and pollutants are frequently those that you can’t see, but fortunately, these air-cleaning plants can help you get rid of toxins and enhance the quality of your air.
Here is a list of the top indoor plants that clean the air and give some colour to your home, according to NASA’s Clean Air Study.
Devil’s Ivy or pothos (Epipremnum aureum)
Devil’s ivy, also known as pothos or golden pothos, is an indoor houseplant that is simple to grow and will combat common household pollutants. It thrives in water, pots, and hanging baskets and offers instant colour to any space with its flowing tendrils. It’s also been said that the heartleaf philodendron is more difficult to destroy than to maintain alive!
Which plants purge air pollutants the fastest?
Many of my general biology labs are being moved online by me (because of COVID, ya know). I’m trying to think of a few nice plant experiments, and plant air purification struck me as a potentially entertaining direction to take. Do you have any references regarding how plants can reduce airborne pollutants and dust? It would be amazing if you could share anything!
Are plants a better air cleanser than filters?
We regret having to inform you, but no. In any actually achievable number of houseplants, and most definitely not in an average number of plants way. Sadly, it is largely untrue that plants can successfully purify indoor air.
Of course, plants take in carbon dioxide, undergo photosynthesis, and release oxygen back into the atmosphere. The underlying hypothesis was that plants could be able to absorb other air pollutants, such as volatile organic compounds, in addition to carbon dioxide (VOCs). This is accurate in theory. However, houseplants don’t qualify as air purifiers because of how slowly they can remove VOCs from the air.
Do indoor plants reduce dust?
Large, glossy, and waxy houseplants have a lot of surface area that can attract and collect dust. Indoor plants work similarly to their outdoor counterparts by unambiguously trapping these dust particles and releasing fresh air.
Which plant produces oxygen continuously?
A folktale holds that sleeping under a peepal tree drives ghosts away, but science contends that doing so lengthens life since the tree releases oxygen at night. Buy these plants and trees today to live a long, healthy life.
When plants are engaged in photosynthesis during the day, they absorb carbon dioxide (CO2) and release oxygen (O2), and when they are engaged in respiration at night, they absorb O2 and release CO2.
- Pathway C3 (Calvin cycle)
- Pathway C4
- CAM route (Crassulacean Acid Metabolism).
Land plants frequently produce C3 and C4, with C3 being the more prevalent of the two.
Epiphytes and plants from the desert exhibit the CAM pathway (i.e. plants that live on other plants). These plants, unlike C3 and C4 plants, retain their stomata closed during the day and open them at night in order to fix CO2 as malate and release O2.
They act in this way to stop water from evaporating owing to sunshine. Similar to C3 plants, they break down the malate throughout the day and use the CO2 that is generated through the Kalvin cycle to produce sugars. Thus, during the night, CAM plants emit some oxygen.
It is untrue, nevertheless, that they release a significant amount of oxygen during night. In conclusion, the majority of plants only release oxygen during the day; no plants create a significant amount of oxygen at night.
These ten plants undoubtedly produce a lot of O2 during the day and less CO2 at night, increasing the oxygen level.
Aloe Vera
Aloe Vera is always at the top of any list of plants with health benefits. Aloe Vera is one of the plants NASA lists as increasing the air quality since it releases oxygen at night and lengthens human life.
It offers several cosmetic benefits and is practically “no-maintenance.”
Snake plant
It requires little maintenance and thrives in either direct or indirect sunlight. It doesn’t even require very frequent watering because it can survive in dry soil.
In actuality, one of the main issues with snake plants is overwatering. Snake plants are a great option for any area in the house and will help clean the air of formaldehyde.
Areca Palm
Areca palm, which is indigenous to south India and the Philippines, is also known by the names golden palm, butterfly palm, and yellow palm. Areca palms can be kept indoors as houseplants, but they need specific care.
Neem
The Neem tree, which is associated with health advantages, filters the air at night by absorbing CO2.
Neem functions as a natural pesticide, thus it makes sense scientifically that it should be planted within the house, particularly in the middle of the court.
Orchids
Orchids are the ideal plant to place in the bedroom corner since they are both beautiful and helpful.
Along with producing oxygen at night, orchids also expel the paint-related xylene pollution and bring fresh air into the space.
Gerbera (orange)
There are many reasons to enjoy the gerbera flower since it is happy and bright. Gerbera flowers, the fifth most popular flower in the world, are said to represent innocence, purity, and joy.
Gerberas come in a variety of jewel tones, but orange gerberas are the most popular since they can offer a strong pop of colour.
Christmas Cactus
A Christmas cactus may survive in low light, but it thrives in direct, bright light. Less frequent watering of the plants will encourage blooming.
Although the Christmas season is when this ubiquitous house plant blooms, its long, green arms are lovely all year long.
Tulsi
Most commonly called Holy Basil. It is indigenous to India and is primarily grown in south-east Asia. It is frequently used to treat conditions like excessive cholesterol, Asthma, colds, and sore throats.
Money plant
They grow enormous yellow and green leaves on trailing vines and are incredibly durable indoor plants that anyone can maintain.
Choose a sunny location away from direct sunlight, or if it’s more effective, place a pothos in a location with less light.
Through the process of photosynthesis, indoor plants actually release oxygen during the daylight hours when there is ample natural light. However, when there is no light, this process comes to an end. They are lowering the CO2 level at night, which raises the oxygen ratio.
Bring these plants home right away if you’re considering adding a little greenery to your space to improve the oxygen levels in your home during the night.
