How do plants contribute to air purification?

  1. The process of purifying indoor air involves two main processes namely phytoremediation and photosynthesis. The first process involves the absorption of air pollutants and volatile organic compounds through roots and leaves.
  1. These pollutants are further broken through metabolic processes followed by trapping of those in the soil. Plants having large leaves can facilitate transpiration rate at a much faster rate. Those plants can contribute effectively to the process of purification.
  1. Indoor plants can successfully reduce the number of harmful air pollutants such as benzene, formaldehyde, ammonia, xylene and trichloroethylene. Trichloroethylene is mostly present in varnishes and paints, benzene is found in dyes and tobacco as well, xylene is released from car exhaust and lastly, ammonia is present in floor waxes and window cleaners. It will be difficult to escape from the ill effects of these pollutants in absence of common household plants.
  1. The process of photosynthesis functions by the removal of harmful gases from the air through the absorption and breaking down of carbon dioxide exhaled by human beings. 

The soil also contributes additionally by functioning as a filter and trapping the heavy metals and particulate matter that would otherwise affect the surrounding air inside. Below discussed are some effective household plants that can effectively purify the indoor air.

Breathe in Cleaner Air by Growing these Air Purifying Plants in Your Home

When you aim at purifying indoor air, houseplants are a great choice to opt for. However, the claim of replacing indoor air purifiers with house plants has been scrutinized by researchers and came up with a flaw regarding the effectiveness of using houseplants for purifying purposes. 

Several researchers argued that the rate of air exchange is faster in a building compared to those sealed chambers which makes the removal of volatile organic compounds erroneous in real life. Plenty of household plants would be able to eliminate the toxins more effectively.

The discourse regarding the efficiency of houseplants in air purification is still open for further tests and examination. But that doesn’t mean you should stop considering providing space to the houseplants as they share plenty of added benefits that make it worth adding to your indoor space.
