Houses are prone to air pollutants that are found in carpets, cleaning solutions, glues, ovens and synthetic materials such as fiber, rubber, and plastic. National Aeronautics and Space Administration (NASA) conducted a study in 1989.  The study showed that various house plants can be used to purify a home by removing volatile organic compounds present in our homes. 

Air Purifying Plants

 

Scientists found out that many plants that are used for air purification are from tropical forests. As their leaves allow photosynthesis, the air is moved efficiently in low light conditions. The roots of the plants and the soil itself also remove the pollutants in the air. This is because the fungi and bacteria in the soil use the pollutants as a source of food for the plants. If you can remove the lower leaves of the plant for exposure to more soil, more toxins can be absorbed.

How Many Plants Do I Need to Purify Air?

The NASA scientist who did this study, Bill Wolverton, provides a recommendation on the number of plants that can be used in a room for air purification. He suggests that for a room measuring 100 square feet, at least two good-sized plants can be used. When the air cleaning plant is bigger and leafier, the better the air purification. This is because the surface area of the leaves influence air purification

A different study that was funded by Hort Innovation showed that an average room that is roughly 13 by 16 square feet or 4m by 5m can use just one houseplant. This improved the air quality of the room by 25%. When two plants were used, the air improved by 75%. In larger rooms measuring 26 by 26 feet or 8 by 8 meters, air quality improved by 75% when 16 plants were used. 32 plants were found to produce better results.

Are Plants Better Than Air Purifiers?

We can’t easily point out which is the best for air purification, but some tips can help you determine which is the best for your home. 

Air-purifying house plants can be preferred for:

  • Homes with less pet dander or dust
  • People who are good and passionate at growing these plants
  • People who like purifying air naturally
  • Homes that have enough space for the accommodation of various plants
  • Homes that have higher VOCs levels from new furniture, new construction, higher amounts of cleaning products, and many more.
  • People who are keen on keeping toxic pollutants from their homes by following extra steps.

Mechanical air filtration by air purifiers can be preferred for:

  • For people who want to eliminate a wide variety of contaminants from the house
  • People who have no issue with using mechanical filtration
  • Homes that have limited space to accommodate multiple plants
  • For people with allergies or asthma
  • Homes with a lot of pet dander or dust
  • People who aren’t passionate or good at keeping house plants alive and healthy.

Having mentioned that plants can be used to eliminate toxins and other pollutants in the house, it’s inevitable to wonder whether sleeping in the same room with plants is healthy or not. 

Is It Okay to Sleep with Plants in The Bedroom?

The Clean Air Study that was conducted by NASA provides facts on how the plants can purify the air. Most people believe that sleeping with plants in the same room isn’t healthy. This shouldn’t be the case since respiration in plants occurs as in humans.

During photosynthesis, plants release carbon dioxide at night and convert carbon dioxide to oxygen during the day. It’s important to note that the amount of carbon dioxide released by the plant is far less than what humans and pets release. This could mean that sleeping with someone else in the same room is less healthy in terms of oxygen compared to sleeping in a bedroom filled with plants. 

It’s more beneficial to have plants in your bedroom since apart from cleaning the air in the room, the bedside table is brighter and the room looks more alive. Moreover, as you take care of the plants, you can wind down easily after a busy day. Some studies have shown that by just touching a plant’s leaf for two minutes, your stress levels can be reduced.
