Did you know that it is recommended you place two average-sized plants per every 100 square feet of your indoor space? Yes, but don’t just put any plant. Choose one good air purifying plant to place there.
That aside – for a moment…
What is the one thing that your apartment or office may have in common with a NASA spaceship? Regrettably, the answer to this question could be the presence of low-quality air. Currently, indoor air pollutants rank among the most common public health risks, as far as environmental risks go.
- When your house has a stagnant indoor air environment, pollutants to start building up.
- In the end, they tend to stick around for much longer than you would like, which is why humans breathe them in.
- When you work and live in a place that is filled with all kinds of contaminants, you are likely to get the sick building syndrome.
- The syndrome can cause irritation of the nose, ear, and eyes, headaches, nausea, and dizziness.
But this no longer needs be the case as you can use houseplants to purify your air. Below is our list of the best air purifying plants you can place in your bathroom, bedroom and pretty much every indoor space you have. I will also guide you on how to choose plants for your house, with a little information from a NASA study on these plants.
About the 1989 NASA Experiment
Plants are an important part of our life. They are able to convert the carbon dioxide expelled by human beings through the breathing process into oxygen through a process known as photosynthesis.
A NASA experiment published in 1989 established that it is possible for plants to scrub the air and eliminate organic compounds, e.g., benzene and formaldehyde which have been known to cause cancer.
In conducting this experiment, the researchers from NASA were hoping to find ways that they could use to detoxify the air found in the space stations.
Recent research has indicated that potted plants have soil micro-organisms which can play an essential role in cleaning the air found indoors.
The results of the NASA experiment showed that houseplants could be used as natural air purifiers, and the bigger the leaves in a plant, the better it was at purifying the air. According to Bill Wolverton, a former researcher with NASA, and who was involved in the 1989 experiment, the amount of leaf surface area can impact the rate at which air is purified.
He goes on to say that it may be impossible to determine the total number of plants required to do away with contaminants in an ordinary room, but he does recommend having at least two average sized plants for every one hundred square feet of interior space.
According to Bill, the Boston Fern is an effective plant when it comes to eliminating air pollutants, but the plant is very difficult to grow in the house. He goes on to recommend the golden pathos as his preferred choice not only because of its popularity but because it is very easy to grow as well.
Best air purifying plants for indoor use
Even though indoor plants can be intimidating to people who have the fear of commitment, you will be surprised to learn that many plants are actually very easy to care for.
Actually, you would have to try really hard for you to be able to kill some of these plants. Below is a list of plants that were identified in the NASA study mentioned above as being the best for indoor use.
For each type of plant, there is an environment it favors, and you should, therefore, ensure that you do proper research to determine the amount of water or sunlight that the plant will need. In case the plant does not come with a pot, or it happens to outgrow its pot, you can always report it.
All you need to do is find a pot that is at least an inch bigger than the pot you previously had, add some soil to its bottom, and then add this plant to the top part of the soil, to ensure that the soil level will not change, and will remain in the same position it was previously.
Once this is done, all you need to do is add some potting soil around the plant’s edges, add some water and you will be done.

How to choose the right indoor air cleaning plants
A little imagination can reveal a lot of space to place your houseplants regardless of how crowded the home may appear to be.
Great spots for best air purifying plants include bathroom corners, on your bookcase, on the piano, and even on top of your refrigerator.

Consider adding some plant food to ensure that they have all the nutrients they need to continue growing.
How do you choose the best air purifying plants?
Match your plants according to the available space
You need to take a critical look at your space before you can choose your preferred houseplant. When you have a small apartment or office, you may not have enough space to hold the Dracaena plant, but you could have enough space for an African violet.
This is a plant that is easy to maintain, produces colorful blooms and is very easy to maintain. Consider hanging a spider plant from the ceiling to assist with purifying the air.
Choose a plant based on the prevailing light conditions
If the room where you want to place the plant does not get enough sunlight, do not choose plants that require lots of light for them to grow. You should go with plants such as the pothos, snake plant, or the Chinese evergreen.
The peace lily is an ideal plant to consider having in your house. It will not only assist in purifying the air by removing the contaminants, but it will also not require a lot of light for it to start growing.
If you come across a plant you like when you are visiting a friend or relative, do not be shy to make inquiries. Ask what it is, where it was purchased, and what it needs for it to continue growing.
You could also make a visit to the local gardening center or nursery to obtain information on the best air purifying plants for indoor use. Additional resources like the internet can also be very helpful.
Alternatively, you could consult with a florist to get information on houseplants that will match what you are looking for, and where to get them.
Use the houseplants to decorate the house
You do not have to be stuck with green houseplants when there are so many other colors to choose from. Consider African violets, paperwhites, and cyclamen to add some color to your house during the early spring months and late winter months.
For great color, all year round, consider including the croton plant for its glorious shades of orange, yellow, and red. You have very many options to choose from to ensure that the house has a vibrant, and radiant color throughout the year.
Choose plants containers that are decorative
You can mix up your container materials, colors, shapes, and sizes. Consider using line wicker style pots, copper pots, and ceramic glazed pots. You could also use shelves and plant stands to add some color to the residence.

Recent studies have indicated that coming into contact with the leaves of a houseplant can actually assist in calming down a person.
Therefore, even though there is no scientific evidence to indicate that houseplants can assist in increasing a person’s sleep quantity, they can assist in transforming the sleeping area into a Zen Den.
This is a transformation that would make it easier for you to fall asleep much faster, as well as stay asleep for longer durations.
