Human life is dependent on plants. They can eliminate contaminants from the air we breathe and change the carbon dioxide we exhale into fresh oxygen through photosynthesis.
Indoor plants help purge the air of cancer-causing volatile organic chemicals like formaldehyde and benzene, according to a renowned NASA experiment that was published in 1989. (Those NASA researchers were looking for efficient techniques to purify the air in the environs of space stations.) Later studies have discovered that soil microorganisms in potted plants also contribute to the purification of indoor air.
Some scientists claim that indoor plants are efficient natural air purifiers based on this research. The quantity of leaf surface area determines the pace of air filtration, according to Bill Wolverton, a retired NASA research scientist who conducted that 1989 plant study. And the bigger and leafier the plant, the better.
According to Wolverton, it’s impossible to predict how many plants could be required to completely purge a room of its impurities in the absence of pricy testing. He does, however, typically advise at least two “excellent sized plants per 100 square feet of indoor space.” One of the best plants for eliminating airborne contaminants is the Boston fern, although it might be challenging to cultivate it inside, according to him. “The golden pothos is a well-liked and simple-to-grow plant, so that’s usually what I suggest.
While Wolverton has long been a strong supporter of indoor plants—he has written books on the subject and currently runs a consultancy business that promotes their use to purify contaminated air—other experts contend that the evidence supporting their ability to do so is far from clear-cut.
According to Luz Claudio, a professor of environmental medicine and public health at the Icahn School of Medicine at Mount Sinai, “There are no conclusive studies to indicate that keeping indoor plants can considerably boost the air quality in the home to benefit health in a meaningful way.
Claudio has examined the studies on the advantages of indoor plants on the quality of the air. She claims that under “laboratory circumstances,” there is no doubt about the ability of plants to remove volatile chemical pollutants from the air. However, there isn’t much solid scientific evidence to support the idea that adding a few plants to your house or office will help to filter the air there.
The majority of research projects to date, including the NASA study, placed indoor plants in restricted spaces to gauge their ability to purify the air. Stanley Kays, an emeritus professor of horticulture at the University of Georgia, claims that those studies aren’t really relevant to what takes place in a home.
A 2009 study on the purifying properties of 28 various indoor plants was co-authored by Kays. While many of those plants were capable of purging the air of contaminants, the author claims that transitioning from an enclosed container to an open atmosphere drastically alters the dynamics.

13 by 16 feet) increased the air quality by 25%. Two plants resulted in a 75% improvement.
32 facilities emitting those gases were required to provide a 75% increase in the quality of the air.
How many indoor plants does NASA advise having?
Although you might not immediately link NASA with indoor plants, the research organization conducted a study on plants’ ability to filter the air in the late 1980s. A person’s health depends on their home environment, which houseplants do more than you might imagine. Their primary benefit is that they purify the air, so it makes sense that NASA conducted a Clean Air Study to determine which indoor plants are best at removing benzene, formaldehyde, trichloroethylene, xylene, and ammonia from our surroundings. These chemicals have been linked to negative health effects like headaches, vertigo, eye irritation, and others.
The results of a study conducted about 27 years ago by Dr. B. C. Wolverton show that Peace Lilies and The Florist’s Chrysanthemum are the most effective plants for air purification. A minimum of one plant should be present in every 100 square feet (10 square meters), according to NASA, and although though this research is rather old, many people still consider it to be the most thorough and accurate to date.

Is it beneficial to have numerous plants in your home?
Increased physical health and improved psychological (mental) well-being are two potential advantages that indoor plants may provide for humans (i.e. they support fitness and general health). The following are some of the psychological advantages of indoor plants: a happier mood. lower levels of stress.
What percentage of people have indoor plants?
Highlights of the data on indoor plants:
- Seven out of ten millennials identify as plant parents.
- Seven houseplants per typical plant parent have perished.
- Demand for houseplants increased 18% during the Covid epidemic.
- At least one houseplant is kept in 66 percent of American households.
- Interacting with indoor plants for just 15 minutes can alleviate stress.
- Up to 15% more productivity is gained from indoor plants.
- Less sick days are taken by employees whose workplaces have more plants.
- In just 24 hours, houseplants can eliminate up to 87 percent of airborne pollutants.
- Each year, the typical household spends $608.54 on gardening supplies.
- Adults who produce food plants or want to do so make up 67% of the population.
in 10 millennials call themselves a plant parent.
It’s no secret that the once-forgotten passion with houseplants is returning, particularly among millennials.
The term “plant parent,” which was coined by millennials, describes taking care of indoor plants. The plants they actually look after are called plant babies. Plant parenting offers a sense of purpose and delight but requires far less effort and commitment than raising actual children or animals. (1)
A rising trend among millennials is plant parenting, which is made more challenging by the fact that many of them have delayed having children and would rather rent than own homes.
Seven out of ten millennials identify as “plant parents,” according to an article and OnePoll 2020 poll on the generation and plants. In other words, taking care of houseplants is more than simply a hobby for millennials; they regard themselves as taking care of their plants like a parent. (2)
The study examined the interactions of 2,000 millennials with plants. The findings also show that 40% of millennials intend to purchase a new houseplant this year, while 48% of them doubt their ability to maintain plants.
Average plant parent has killed seven houseplants.
The typical plant parent has lost seven indoor houseplants that they have brought home, according to a 2020 Article and OnePoll study on millennials and houseplants. And 67 percent of them identify as plant killers. (3)
The study also identified the primary concerns millennials have with plants. Top five are as follows:
Four out of five survey participants also believed that plant parenting had improved their ability to take care of themselves.
As more individuals work remotely and spend more time at home, it will be interesting to watch how the trend of millennial houseplant ownership develops.
Houseplant demand surged 18% during the Covid pandemic.
It’s not surprising that demand for everything has increased due to the Covid epidemic, even houseplants. Before COVID, plant parents, plantfluencers, design fads, and plant collectors set the houseplant craze in action.
In order to determine how the popularity of houseplants has impacted their plant sales figures, Garden Center magazine in the United States and Canada interviewed independent garden center managers and owners in 2021. (4)
Over 20% of houseplant sales in garden centers are now coming from indoor growing, an increase of 18% from the previous year. And there are no signs that this expansion will soon slow down.
The fact that two-thirds of nurseries in the U.S. raised their houseplant costs by more than 15% in 2020 and intend to do the same in 2021 is one of the most intriguing houseplant sales data.
% of American households own at least one houseplant.
American consumers’ ownership of plants has steadily increased since 2019 among consumers. According to statistics on indoor plants, 66% of Americans have at least one houseplant in their residences. (5)
Additionally, only 26% of consumers said they had no interest in purchasing a home plant.
The fact is that one of the most popular pastimes in the United States is indoor gardening. Approximately 27 percent (33.1 million) of American homes actively engage in indoor houseplant growing, according to the figures. (6)
Here are the top plant queries from our analysis of the most popular Google searches about indoor plants in the United States to help you better understand the popularity of houseplants. (7)
Only 15 minutes of interaction with houseplants reduces stress levels.
We are more linked to the internet than ever before, yet this increased connectivity also comes with a lot of stress (e.g. technostress and loneliness). Our failure to manage ever-evolving technologies in a healthy way results in technostress, a modern sickness. (8)
When you engage with houseplants, you can feel more at ease, at ease, and natural, according to a study that was published in the Journal of Physiological Anthropology. (9)
One of the two tasks was carried out by study participants. Repotting a houseplant was the first assignment, and a quick computer task was the second. Researchers examined physiological and psychological stress indicators 15 minutes after each activity.
The analysis of the data revealed that through inhibiting the autonomic nervous system’s activity, indoor plants lowered psychological and physiological stress responses. The interaction with plants only made people feel more at ease, at ease, and natural after fifteen minutes.
Researchers came to the conclusion that engaging with indoor plants actively could lessen physical and mental stress. This implies that residing among plants can significantly improve our mental wellness.
Numerous other research have confirmed the benefits of indoor plants in reducing physiological stress and adverse psychological effects. (10, 11)
According to the most recent studies, indoor plants are one of the simplest and most efficient ways to lower stress levels in indoor settings, fueling the indoor plant craze.
People with more plants in their workspace take fewer sick days.
The impact on productivity is one of the statistics about indoor plants that is most intriguing. Numerous studies have found that having indoor plants in the office boosts focus and productivity by 15%.
According to research, green offices boost productivity more than lean interiors without any vegetation. In major commercial offices in the UK and the Netherlands, productivity levels were investigated and tracked by University of Exeter academics. (12)
Simply introducing plants to previously empty workplaces enhanced productivity by 15%, according to the study’s findings, which are in line with other laboratory studies.
In order to evaluate the psychological advantages of indoor plants in workplaces, another study was carried out in Norway. (13)
Researchers estimated the relationships between plants and a number of frequently researched workplace variables and stress, sick leave, and productivity using hierarchical regression models.
Researchers discovered a link between productivity and the quantity of plants visible.
An further intriguing study supports the idea that plants increase productivity.
A single plant significantly improved the performance of a creative assignment, according to a 2002 study. (14)
The plant closest to the participant’s position had the biggest impact, according to their investigation into the plants’ visibility and positioning.
This implies that having plants around your work environment, whether it be in the office or at home, has a significant favorable effect even if you aren’t a houseplant fanatic.
Houseplants remove up to 87% of airborne toxins in just 24 hours.
The ability of indoor plants to purify the air is probably one of the greatest quantifiable data concerning their advantages.
NASA (15) research from 1989 revealed that houseplant roots and soil considerably reduced airborne pollutants.
Finding a method to eliminate volatile organic compounds (VOCs) from the air would help a spacecraft’s air quality, which was the aim of the research.
The effectiveness of plants’ leaves, roots, soil, and related microbes in purifying the air was assessed in the study.
According to the research, the foliage of ordinary plants can reduce indoor pollutants like formaldehyde and carbon monoxide by up to 87 percent in just 24 hours.
The removal of several indoor air pollutants like ozone, toluene, and benzene by plants was further supported by studies. (16)
The NASA study has drawn a lot of criticism because it was carried out in airtight, controlled chambers and cannot be replicated in a typical office or home environment.
The air cleaning effect does, however, scale up to a building level, according to recent studies. (17) Researchers employed three planting regimens in 60 offices for a field investigation they carried out in 2006.
Researchers discovered that levels of airborne pollutants were reduced by 50–75% in every workspace, indicating that millennials’ rising fascination with plants may be good for the environment.
Together, the results show that indoor plants can reduce indoor air pollution in a sustainable, affordable manner while also enhancing productivity and well-being in people.
The top ten houseplant air cleaners listed below are the most efficient at removing volatile organic compounds (VOCs) from the air while still improving the quality of the air in homes and offices. (18)
- Palm areca
- female palm
- palm bamboo
- Rubber tree
- Dracaena
- British ivy
- Little date palm
- Ficus
- Brooklyn Fern
- Calm lily
Average household spends $608.54 per year on gardening goods.
A report on plant trends by the National Gardening Association in 2021 revealed that millennials were responsible for 25% of the record $52.3 billion in lawn and garden purchases made by American gardeners in that year. (19)
The poll also revealed that the average family (in the 35–44 year old age range) spent $608.54 year on gardening supplies, an increase of $105.54 from the previous year (20), indicating that this plant hobby is becoming increasingly popular.
The vast majority of survey participants in this category are bringing up families, own homes, and have stable careers.
It makes sense that gardening interests people. Community garden data show that for every dollar spent on gardening, about $6 worth of produce is produced.
% of adults are growing or plan to grow edible plants.
Growing edible plants has several benefits, including cost savings on groceries, access to the freshest foods, and teaching children about a healthy lifestyle.
Statistics on indoor gardening demonstrate the increased popularity of owning and cultivating plants. According to the 2021 Garden Trends Report, 67 percent of adults grow food plants. (19)
Additionally, during the Covid-19 outbreak, followers on plantfluencers’ and garden influencers’ social media channels increased by up to 400 percent.
Younger gardeners’ interest in plants is mostly motivated by growing food and participating in a shared activity with family, according to a survey on plant data by the National Gardening Association done in 2021.
However, older gardeners are mostly motivated by the beauty that plants offer and the need to get some exercise. (21)
