And as far as the first myth -- that you get more oxygen with a houseplant around -- Waring said that because ventilation provides constant air from outside, lack of oxygen is never a problem. Bacteria: 0.5 – 10 microns People spread bacteria through the air when they cough and sneeze, transmitting respiratory diseases and triggering symptoms in asthma sufferers. So a single spider plant, which is thought to be one of the better plants for cleaning indoor air (according to this study), removes so little PM from the air that you’d probably need a few thousand of them to clean even a small fraction of indoor air. "[The studies] would take a potted plant and put it in a small chamber ... three feet by three feet by three feet ... and they would inject a particular volatile organic compound (VOC) into the chamber ... and watch it decay over time, and that decay is what they would contribute to the plant clearing the VOC," Michael Waring, one of the study's authors, told CNN. All houseplants clean the air around them. Here are our tips on the best plants to use to achieve clean air solutions, this World Environment Day and beyond, and help do your bit to fight climate change. Air plants (Tillandsia spp.) You probably learned in science class that plants use photosynthesis to turn carbon dioxide (CO2) into oxygen, making air safer to breathe. Studies have shown that Aloe and Snake Plants are some of the best air purifying plants. In a typical building, it would be nearly impossible for even a large number of indoor plants to keep up with VOC build-up. 10 Air Purifying Plants for a Fresh and Clean Home Back before HVAC air filters and portable air purifiers existed, people had another way of purifying the air in their homes. Tips for Using Plants to Clean Your Air For maximum efficiency, use 15 to 18 plants in a house that’s 1800 to 2000 square feet. One 2017 study measured the effectiveness of five plant species, including popular houseplants like the Golden Pothos and Ficus, in reducing indoor concentrations of ozone.4. With their rich “rubbery” foliage, these plants make charming accents to any home or office. At the end of a two-month period, researchers found, depending on the environment, that the waxy leaves of the spider plants had accumulated anywhere from 13.62 to 19.79 micrograms of PM per square centimeter of leaf area (μg/cm2).1, That’s almost nothing - a microgram is one millionth of a gram, and human beings breathe about 120,000,000 grams of air each day (about four times that much when you exercise).2. The rubber plant is particularly beneficial in eliminating formaldehyde in the air. To decrease even a fraction of the ozone in a 500 square-foot room, you’d need at least 80 plants. Fine particles penetrate deeply into the lungs. A plant needs the carbon dioxide you breathe out and you need the oxygen it gives off. You don’t have to buy that many at first. However, plants are certainly positive. This category also includes dust, some pollen and mold spores. Just how many is not clear. Aloe is an easy-to-grow succulent plant that helps to clear benzene and formaldehyde from the air. Through the bloodstream, they can reach any organ or area of the human body. They usually have strap-shape or slender triangle-shape leaves that grow in a … It also boasts one of the highest transpiration rates on the list of plants that clean the air. These house plants leave the air cleaner in your home and healthier.. Did you know that we now spend on average 90% of our time indoors! IQAir is a Swiss-based air quality technology company empowering individuals, organizations and communities to breathe clean air through information and collaboration. And, it has smaller particles than mainstream smoke, which make their way into the lungs and the body's cells more easily. We share the best indoor plants for clean air! [3] Yang H, et al. Thousands of cubic feet of air pass through a home each day, and plants can only remove a miniscule amount of PM from all that air. According to The EPA our indoor spaces often have up to 5 times higher concentrations of some pollutants than outdoors.. You can help reduce these pollutants by cleaning and deep cleaning your home often. In this study, researchers placed spider plants in environments with varying levels of exposure to indoor PM, including a dental clinic, a room used to bottle perfume, a typical suburban home, an apartment, and an office. Don’t burn wood or other solid fuels inside. Unlike the NASA study, this study was conducted on a building site rather than in a laboratory, and the researchers measured ambient concentrations of VOCs in a room in the building before, during and after putting plants in the building. If they can turn carbon dioxide into oxygen, they can turn pollutants into clean indoor air, right? Pet Dander: 0.1 – 25 microns Pet dander is the old skin and fur that pets shed. DOI: 10.5620/eht.e2017006. Examples of PM10 include coal dust, fly ash, some components of wood smoke, asbestos fibers, and roadside particles from tires and brakes. Bacteria can also grow inside poorly maintained ventilation systems, which spread it into the circulating air. Please try again. When you’re out in the woods or around a lot of plants, that clean fresh air you’re smelling is exactly that. Plus, it also aids in removing carbon monoxide. Pet dander is a known asthma and allergy trigger. Try the following to increase your awareness of indoor air pollution and empower yourself to do something about it: Using plants will do little to clean your indoor air, while changing your indoor habits can drastically improve your IAQ. While one plant may clean the air in a small, confined space, getting those same results for a whole house would require many more plants. Updated 1326 GMT (2126 HKT) November 12, 2019. Houseplants are not actually cleaning the air, a study says "That does occur in the chamber, but it's the microbes that are absorbing the VOC, not the plant itself.". This is a good thing for your power usage and electricity bills. They are not generally inhalable directly into the lungs. The Peace Lily is one of the most visually appealing plants on the list with its unique white flowers. (CNN)You've probably heard people say that keeping plants in your home or office helps to make the air cleaner, but science says otherwise. Ultrafine particles are airborne particles less than 0.1 microns in diameter. Part of the … Preliminary results showed that the plants removed anywhere from 10 to 90 percent of these chemicals within a 24-hour period in a sealed environment filled with high amounts of the chemicals. Houseplants' air-cleaning and oxygen-producing benefits may have been exaggerated, a new study says. In the report, NASA detailed a study of 12 different plant species thought to be able to remove gas concentrations from enclosed, airtight spaces. Flamingo Lily. Plants do indeed absorb gases from the air and metabolize them into oxygen and other, less toxic compounds. But more dubious is the question of whether plants can do anything to improve your Indoor Air Quality (IAQ) by purifying the air of pollutants. Among the most effective plants that clean the air are six succulents. They don’t clean the air “any more than an old pair of socks or baseball cap that I would hang on the wall.” Wow. Phytoremediation on air pollution. You might as well live in a jungle! Interior landscape plants for indoor air pollution abatement. But this study was not without several significant constraints: More recently, a 2017 study built on NASA’s findings by using three types of Ficus plants:6. In fact, there are many health benefits to being near plants. The answer is more complicated than you might think. The researchers also measured the levels of gases in a room in the same building without indoor plants to ensure that any noted gas reductions were indeed connected to the use of plants. The study further suggested that efficient air cleaning is accomplished with at least one plant per 100 square feet (9.3 m 2) of space, but was conducted under sealed space station conditions and research conducted since has shown mixed results in the home or office. More significant in the research about plants and indoor air is the effect of plants on indoor volatile organic compound (VOC) build-up. The rubber plant is another of top 10 plants that clean the air. They thrive in warm, humid, dark conditions such as mattresses, carpets, sheets, pillows, and upholstery. Plants, on the other hand, will turn carbon dioxide back into oxygen through photosynthesis. Fine particles (also known as PM2.5) are particulate matter that is less than or equal to 2.5 microns in diameter. Thanks to the Nasa Clean Air Study, we now know which are the best air cleaning houseplants that you can buy and you’ll be extra pleased to know that practically all of them are virtually indestructible. There was also no standardized metric for how the reports were recorded, Waring said, so the study used the clean air delivery rate to predict the effectiveness of plants in a real building. However, the hidden cost of energy efficiency is a much lower amount of fresh air exchange with outdoor air. As a result, researchers have undertaken many studies on plants to remedy this problem. With the advent of energy-efficient construction, more buildings have become airtight so that heating, ventilation, and air conditioning (HVAC) systems don’t have to work as hard to heat or cool an indoor space, meaning that they use less energy than traditional systems. (2015). Research does indicate that plants have a limited ability to lower concentrations of certain gases and chemicals from indoor air (more on that in a moment). If photosynthesis can turn a harmful gas into one of the most important molecules we breathe, the notion of plants absorbing pollutants and turning them into clean indoor air doesn’t seem like rocket science, right? Think one plant for every 100 square feet. 4. (2011). Fine particles penetrate deeply into the lungs, into areas known as small airways and into the primary air exchange areas of the lungs. Circulating outdoor air through a house by keeping doors and windows open, or at least slightly ajar, may reduce the risk of hay fever-causing dust. Harmful indoor particulate matter includes PM10, which encompassed larger particles like coarse dust, mold spores, and pollen, as well as PM2.5, which includes bacteria, viruses and ultrafine particles from vehicle exhaust that can easily get inside if your home or office is close to a busy street or a highway, even if the building is airtight. If your plant gets dusty, just wipe them clean with a clean sponge. Animal dander is very small and can become attached to your clothingeven if you do not own a pet. You've probably heard at some point that house plants are good for your health because they can clean, filter and purify the air of various toxins and pollutants. Plants can transform gases into other, often less harmful substances, but the small scale at which they do so hardly makes them a remedy for indoor gas build-up. (1989). This study has been the basis for newer studies about indoor plants and their air cleaning abilities. Most pollen that produces allergic reactions is from trees, grasses, and weeds. are epiphytes, meaning that in nature they grow on other plants, usually on tree branches.There are hundreds of species and varieties of air plants. So it is essential to manage dust and airflow. Many articles rave about using plants to clean indoor air. There are two primary myths about keeping plants in indoor spaces: one is that you get more oxygen with a houseplant around, and the other is that the plant helps clean the air. In colder climates, occupants seal even the smallest air gaps, and eliminate outside fresh air circulating inside the house. Plants do transform gases into less harmful substances, but the small scale at which they do so hardly makes them a remedy for indoor gas build-up. Of course, All plants improve the air quality of our homes but some are far more effective at doing it than others. The #1 room air purifier for allergies and asthma. they represent more than 90% of all airborne pollutants. List of air-filtering plants Study of the removal difference in indoor particulate matter and volatile organic compounds through the application of plants. At least, not the way that a typical air purifier does, using filtration media (such as HEPA or HyperHEPA filters) to remove a high percentage of particulate matter (PM) from the air. Answer 2-3 simple questions and we'll help you quickly find the perfect air cleaning solution. (2017). Dust mites themselves do not cause an allergic reaction, however, their dung-pellets are an irritant to sensitive people and can cause breathing difficulties. Thus. [2] Koenig, JQ. Many articles rave about using plants to clean indoor air. Creates cleaner air: What NASA found in its studies showed that both plant leaves and roots remove toxic vapors. Studies by NASA prove certain plants help keep the air in your house cleaner and increase oxygen levels. In a typical building, it’s nearly impossible for even a large number of plants to keep up with VOC build-up. All plants are capable of absorbing gases through pores on their leaves. There has been so much interest and research involving plants as air purifiers that there is now a word for it – “phytoremediation.” Studies show that our indoor air may contain over 900 dangerous biological and chemical pollutants. Fungus spores have been known to increase the chances of developing asthma. Myths and facts debunked, The test chambers in which the plants were placed, Rubber plants, which are used to make latex. You might as well live in a jungle! At the same time, it’s removing the toxins from the indoor air. The belief that plants are filtering and purifying the air around us can be traced to a 1989 NASA study showing that indoor plants do in fact help reduce volatile organic compounds (or VOCs) in small, sealed spaces, such as onboard NASA missions. Plants aren’t miraculous indoor air cleaners by any means, so why all the fuss about using plants to clean your indoor air? Anthurium andraeanum. In 1989, NASA compiled a list of indoor plants that clean the air and remove toxins. many gases and compounds commonly found indoors, such as VOCs and even ozone, which largely originates outdoors, can build up to dangerously high levels in energy-efficient homes because there isn’t as much ventilation to disperse them once they get inside. The answer is more complicated than you might think. Think about that: to decrease even a fraction of the ozone in a 500 square-foot room, you’d need at least 80 plants. Phytoremediation of particulate matter from indoor air by Chlorophytum comosum L. plants. Here is a round-up of the best air purifying indoor plants using NASA's Clean Air Study that will add a touch of colour and clean air to your home.
