Indoor Plants: For Fresh Air to Breath

Introduction

Living in an energy-efficient, modern building can have unintended side effects. One of these side effects is less airflow. Lack of airflow allows for indoor air pollution to build up and cause health issues like asthma or sick building syndrome.
In fact, modern furnishings, synthetic building materials, and even your carpet may carry more chemicals than expected. These chemicals can make up to 90 percent of indoor air pollution.

Plants to the rescue

In 1989, NASA discovered that houseplants can absorb harmful toxins from the air, especially in enclosed spaces with little airflow. This study has been the basis for newer studies about indoor plants and their air cleaning abilities. While plants have less horsepower than air purifiers, they’re more natural, cost-effective, and therapeutic.
Plants are also known to:

  • increase mood and productivity
  • enhance concentration and memory
  • reduce stress and fatigue

NASA recommends two or three plants in 8 to 10-inch pots for every 100 square feet. Some plants are better at removing certain chemicals than others. Household chemicals come from objects and materials like:

  • carpets
  • glues
  • ovens
  • cleaning solutions
  • synthetic materials such as plastic, fiber, and rubber

You’ll benefit the most when you include a variety of plants in a room.

Plants that are easy to care for

For people who want to try out their green thumb first, these plants may be for you. While they don’t require daily care, most of them will thrive better if they get fertilized once a month.

Chrysanthemums (Chrysanthemum morifolium)

Florist’s chrysanthemums or “mums” are ranked the highest for air purification. They’re shown to eliminate common toxins as well as ammonia.

Treat yourself to a fresh pot, as this flower only blooms for about six weeks. Or you can fertilize the pot again in the spring when new growth appears. But without the flowers, it won’t be purifying the air. If you don’t want to wait, you might want to just get a new pot.

Plant care: Check the soil’s moisture every other day, and keep it damp.

Toxic to animals: Even though it has a friendly name, mums are toxic to both cats and dogs.

Eliminates: formaldehyde, xylene, benzene, ammonia

Plants that need a little extra love

These air-purifying plants are ideal for people who want to spend more time with their plant. All of them require fertilizer once a month, as well as extra care like misting or repotting.

Plant care: Water generously during growth, but don’t overwater during the winter.

Toxic to animals and humans: Although the English ivy thrives almost anywhere, it’s known to cause problems in dogs, farm animals, and humans when eaten. The chemicals in the sap can also cause severe contact dermatitis in humans, especially those with sensitive skin.

Eliminates: benzene, carbon monoxide, formaldehyde, trichloroethylene, and more

null

Rubber plants (Ficus elastic)

Rubber plants are evergreen trees from India. Their roots grow upwards and often become entwined around the plant’s trunk, forming interesting shapes. These plants love bright, filtered light and a little attention now and then.

Plant care: Water moderately to keep the soil moist, especially in the winter. Prune the leaves and wipe them down to keep them looking pretty.

More ways to purify the air in your home

Besides houseplants, there are other ways you can purify the air in your home:

  • Keep your floors clean by vacuuming and mopping.
  • Avoid synthetic cleaners or air fresheners.
  • Reduce humidity in your air.
  • Increase ventilation.

In fact, some studies also used air filters in combination with plants. So if you’re new to planting or don’t have enough room, purchasing an air filter is one easy step to cleaner air.
