In today’s world, it is hard to escape from air pollutants. Whether it’s from the chemicals we use to clean our homes or even the furniture themselves, we are surrounded by them every day. Many people claim to suffer what is called “Sick Building Syndrome”; caused by pollutants in the air that we might not even realize are there. Luckily, studies have shown that simple house plants can actually help to combat these unpleasant effects. Plants naturally help to clean air and are cheaper, and more pleasant, than a bulky air cleaning machine. Most plants will help, but there are some that are shown to do a particularly good job at it. Below are several air-purifying house plants for your home or office.
What To Pick?
With so many choices of good air-purifying house plants to pick from, it can seem difficult to know which one to start with. The most important thing to keep in mind is the growing conditions in your home. If you have a lot of natural light that’s great for growing, and you’ll have a lot of options. If you don’t get much natural light into your home you’ll be best served looking into plants that require a little less light. You can always set up artificial lights, but for many this extra work is overkill for growing a few small indoor plants.
Also, keep in mind the amount of space you have. Some plant varieties can get quite large, and in a smaller apartment, this may not be the best. Getting a smaller plant, or several of them, might fit your space better.
How Do Plants Purify the Air?
Before we jump into looking at the plants it’s important to know how they play a role in cleaning the air. The most obvious reason is through photosynthesis which converts carbon dioxide we exhale into breathable oxygen.
Plants, as well as soil microorganisms, have also been shown to remove cancer-causing contaminants in the air as well. A study NASA did in 1989 looked at air-purifying house plants and the levels of certain toxins in the air. They found that plants can actually scrub the air of certain organic compounds like formaldehyde and benzene, neither of which is good for you. This research was originally done to keep the air clean on space stations, but the same principles apply to your home.
This research has more recently been called into question, but further research is likely needed for a definite answer.
With that in mind, we’ve picked out a couple of the top air-purifying indoor plants. While all plants will purify your air to some degree, the ones below are generally seen as better than other plants.
