5 Air Purifying Indoor Plants
When vine-curious Brooklynites walk into Tula Plants and Design —a small houseplant shop in Greenpoint with a vibrant Instagram presence and a profusion of leaves on every available horizontal surface—the employees know what questions to expect.
There are two, according to Ariel Ries, an employee at the store. Of all the s trends that have enjoyed a resurgence in recent years—astrology, Fleetwood Mac, and special-counsel investigations among them—few have shown the explosive growth of houseplants and indoor gardening.
As a young man, I can vouch: I am increasingly the gardener. I own seven plants. Of the 6 million Americans who took up gardening in , 5 million were Millennials like me, according to the survey , an annual poll conducted by a nonprofit advocacy group.
Houseplants have much to recommend them. The Sill , an online plant store that communicates its Millennial bona fides through chunky serifs and large splotches of white space, lists plant species by the airborne toxins they are best at removing. Philodendrons filter formaldehyde.
Yet interest in this particular plant benefit is not limited to the self-care set. The same question has landed listicles in the patrician This Old House , the nerdy Lifehacker , and a doomsday-prepper blog. For several years, research really did suggest that houseplants might cleanse the air of certain pollutants.
Why the confusion? VOCs are regularly released by common household products such as drywall, house paints, nail polish, shampoo, and almost anything with a scent. Their harmful effects can range from an itchy throat to nasopharyngeal cancer. Read: Why pop culture links women and killer plants. This means that they can build up in hermetically sealed environments … such as laboratories or spacecraft. The problem for NASA was obvious. So Wolverton, a former military scientist who began his career studying whether plants could break down Agent Orange, now examined whether houseplants could absorb VOCs.
His report announced a cheerful answer. Wolverton did not respond to a request for comment. That study provides the scientific basis for almost all the plant-and-air-pollution content you see online.
But taking its results at face value significantly overstates the power of plants, he said. Wolverton measured whether houseplants could remove VOCs from an airtight laboratory environment. But a home is not a hermetic chamber. It has open windows and doors, drafts and leaks, and much more clutter. Recently, Waring and his colleagues reanalyzed all studies that have examined whether houseplants can filter the air. They found that some types of plants can remove higher amounts of VOCs than others.
But once you factor in the effects of working in a large room, none of the plants are able to do much. Waring told me to imagine a small office, 10 feet by 10 feet by eight feet. Even if you chose the most effective type of VOC-filtering plant, you would still need one plant per square foot, Waring said. Or as Waring who owns 10 to 20 houseplants recently put it in a presentation for the National Academies of Sciences, Engineering, and Medicine:.
But maybe scientists have been researching the wrong pollutant. Several years ago, a team of researchers examined whether houseplants could remove ground-level ozone. More than million Americans live in areas with unhealthy amounts of ozone, according to the Environmental Protection Agency.
The researchers found that even the most effective plants barely reduced the level of ozone in indoor spaces. He owns no houseplants. Read: Why do these plants have metallic blue leaves? Houseplants are just outcompeted. Gall told me to look at the surface area of houseplants in your home, and then to consider the surface area of every other object in your home—the walls, the spray bottles, the couch cushions, everything.
To start to even marginally reduce indoor ozone, Gall estimated that you would need at least one houseplant for every 20 square feet of floor space. Hilton Carter enjoys having a living system in his space. Carter is a filmmaker and designer whose plant-focused Instagram account has more than , followers. He told me he keeps about plants in his square-foot apartment in Baltimore, roughly one plant for every five square feet.
This humidity, while great in the winter, did somewhat limit his decoration options. Not even Instagram-famous plant density can cleanse a room. In fact, I found only one place that achieved one plant per square foot: Tula Plants and Design. Ries told me that the square-foot store will regularly have more than plants for days after a delivery. On the day I called, it hadAnd Ries, as it happened, was familiar with the original Wolverton study.

Smoke? Pollution? How to keep your indoor air clean
But they can also purify indoor air, say University of Georgia experts. Best air-purifiers Of the species tested, purple waffle plant Hemigraphis alternata best removed VOCs from the air. Other species with superior filtering abilities were English ivy, purple heart, foxtail fern and wax plant. In the study, the plants were tested for their ability to remove benzene, toluene, octane, trichloroethylene and a-pinene, all considered toxic.
By Sharon Dowdy University of Georgia. Martha Stewart says houseplants add to a home's décor. But they can also purify indoor air.
In search of fresh air: NASA lists the indoor plants that will naturally clean your space
Back before HVAC air filters and portable air purifiers existed, people had another way of purifying the air in their homes. Houseplants served as a decorative feature and doubled as a natural air purifier. Today, people still use houseplants as a natural form of air purification, but only a few realize how plants purify the air and which ones are the best at it. Plants are pretty amazing and not nearly as simple as they appear. Day and night, they are performing a process known as photosynthesis. Carbon dioxide is needed along with sunlight and water for the plant to grow. To kickstart photosynthesis, another process called Stomata occurs.
Seed these Indoor Plants to Purify Your Home
Home Special Issues Special Issue 21 2. Acting for healthy indoor air Using plants and soil microbes to Phytoremediation is the process by which plants and their root microbes remove contaminants from both air and water. Those purifying properties have been discovered within the frame of space habitation experiments: in the s, scientists at the John C.
Polluted indoor air can create host of potential health problems, from asthma to hormone disruption to cancer. In , NASA studied houseplants as a way to purify the air in space facilities.

Fresh air is not something we get enough of in modern life, especially as most of us seem to be increasingly stuck inside with our great British weather! Indoor air can be stale, and thanks to modern synthetic materials and temperature regulation, it also contains pollutants and is often well below recommended humidity levels. Synthetic furniture, paints and computers, to name but three, silently pump chemical vapours into the air, while your heating system will dry out your air. The humble plant can make all the difference to the air we breathe indoors. They work hard at cleaning our air of these toxins and releasing humidity back into the atmosphere.
A Popular Benefit of Houseplants Is a Myth
There are lots of ways to live healthier. Eat better. Spend more time outdoors. Get a little more active maybe hit the gym? Through their breathing process, plants add oxygen to our spaces.

Here are three indoor plants that will make your indoor air cleaner:.
NASA Clean Air StudyRELATED VIDEO: A NASA study explains how to purify air with house plants
When researching the potential of life — or at least a space station — on Mars, NASA looked seriously at the possibility of using plants as natural air-con units. Already known for absorbing carbon dioxide and releasing oxygen — nicely complementing humans, which do the opposite — a number of indoor plants also proved useful in removing toxic chemicals from the air, including known carcinogens benzene, formaldehyde and trichloroethylene. You may ask why anyone would have those nasties indoors. Unfortunately, many of these chemicals can be found in tobacco smoke, car exhausts and other fumes that form urban smog, as well as compounds emitted from new carpets, furniture, paint, household cleaners, and also from cooking and gas heaters. The combined effect became known in the s as sick building syndrome.
While researching the ability of plants to cleanse air in space stations, NASA made some fascinating and important discoveries concerning the role that houseplants play here on Earth.
