Ornamental plants have become very popular in recent years, but do indoor plants purify the air?
Since the COVID-19 pandemic began, many of us spend more time indoors, so the importance of indoor air quality has received a lot of attention.
In addition to this Environmental Protection Agency The (EPA) reports that Americans spend up to 90% of their time indoors and pollutant levels can be up to five times higher than outside air. And that’s one of the many reasons why it’s essential to keep the air we breathe indoors as clean as possible.
So home plants are sometimes advertised as a way to purify the air in your home, but is there really any truth to that? Here we explore the science behind plants and their impact on air quality.
Do indoor plants purify the air?
Air quality is generally carbon dioxide, carbon monoxide, nitrous oxide, and Volatile organic compounds (VOC), this may be present in some products and materials in our home.
Use photosynthesis, Plants convert the carbon dioxide we exhale and remove gas from the air through a process called absorption.
In a well-cited 1989 report, NASA Scientist Bill Walberton Houseplants argued that they could provide “a promising economic solution to indoor air pollution.” Wolverton studied the plant’s ability to remove VOCs from the environment and its potential for use in deep space missions. However, recent research has poured cold water into this idea.
scientist A study of the effectiveness of indoor plants for passive ozone removal revealed that foliage plants “at best contribute about 0.9-9% to the indoor ozone removal effect.” Tests conducted in the laboratory to simulate typical US home impacts have shown that foliage plants have little impact on the environment. They suggest that the room needs to be filled with vegetation from top to bottom to make a meaningful difference in the air quality of the house.
A single spider plant does not purify the air, but you may find a green wall covered with plants scientist In the 2020 study. Scientists say that green walls filled with the right plant species “can be used to create horticulturally sustainable interior green walls and improve the health indicators of the building’s internal environment.” I concluded.
Therefore, in sufficient quantities, plants can improve air quality. But what should we buy? Sadly, science has (yet) no answer.
2018 paper published in Trends in plant science We are confident that plants will remove pollutants, but there is little research on which species are most effective. The paper concludes that “the ability of plants to remove indoor air pollutants by stomatal uptake (absorption) and non-stomata deposition (adsorption) is little known.”
Do indoor plants have other health effects?
During the blockade of COVID-19, many of us decided to get our hands dirty and go into gardening – but did this have any health benefits?
Gardening can not only improve mood, but also reduce stress, increase productivity, and even increase tolerance to pain, he said. Royal Horticultural Society.. There is also scientific evidence for these claims. for example, 2020 study on the benefits of foliage plants We found that 323 students provided a mental staycation to improve their mental health by raising the feeling of being “away while at home”.
It’s unclear if plants purify the air, but recent research Princeton University Gardening has been found to be beneficial for physical and mental health.While another study is cited Journal Physiological Anthropology Involving a young adult man, we found that indoor gardening reduced the stress response compared to the requirement to complete a computer task. When asked to sit in front of a computer and complete a task, researchers identified increased blood pressure, heart rate, and stress that were not present when the same group was gardening.
Are indoor plants safe for pets?
There are benefits to introducing more plants and greens into your home, but are indoor plants safe for your pet?
Most people know that lilies are dangerous to cats and tomato plants are dangerous to dogs, but many other species also threaten the health and well-being of our pets.Too many to list here, but there is a complete list of poisonous plants available at ASPCA website..
What if your pet eats your plant? “In many cases, animals remain asymptomatic or are just gastrointestinal upsets. There are some cases with more serious clinical effects,” said Alexander Campbell of the Veterinary Poisons Information Service (VPIS). Said.
One of the biggest challenges for a veterinarian is knowing what the pet has ingested. Researcher’s attention.. What is an easy solution? Remove known contaminants from your home or garden.
So we covered how plants affect the air in our homes and whether they are harmful to our pets. And plants can make your home a more comfortable environment, and caring for them can bring benefits to your mental health, but unless you intend to buy hundreds, they It is unlikely that you will do much to purify the air. Therefore, if you are concerned about the air quality of your home, we recommend investing in an air purifier, preferably one with a high quality HEPA filter.
