Air quality is one of the main reasons for feeling good, both at home and at work. This is not just about the outside air, but rather about the quality of the air in rooms where we spend a lot of time, such as in the office, in the living room or in the classroom.
The air quality in these areas is negatively influenced by chemicals released not only by furniture, clothing, carpeting, wall coverings, paint, printers etc. etc, but also by people themselves.Research has shown that plants are able to absorb these substances from the air and thereby purify the air.
Every plant produces oxygen to a certain extent, but not all plants also have air-purifying properties.
* harmful gases are neutralized by absorbing and breaking them down.
* Improves humidity through the regulating evaporation process.
* The air is made more vital because CO2 is converted into oxygen.
A PLANT PROVIDES FOR LESS SICK EMPLOYEES - TRUE
What a few plants in the workplace can't do. People get sick less quickly and function better.

People find a workspace with plants more attractive than a space without plants. Plants provide higher humidity, contribute to a more positive mood, lead to more satisfaction among employees about their own performance and to less absenteeism due to illness. This is the conclusion of new research by Wageningen Environmental Research, part of Wageningen University, in collaboration with scientific company Fytagoras, which specializes in plant research.
Which and how many plants a work floor needs depends on several factors, such as the size of the room and the amount of natural light that comes in. The Grass Lily (Chlorophytum comosum) is often used as a reference plant to calculate the required amount of leaves, says Tia Hermans, project leader of Wageningen Environmental Research. “Then you need about one per 2 square metres, assuming a pot size of 10-12 centimetres..”
The costs of purchasing and maintaining plants can be recovered within one year. Mainly due to the lower absenteeism and better functioning of employees, the researchers say. After that, the investment in plants actually yields money.
The research was conducted at various companies and healthcare institutions. Every company always has a space with workplaces equipped with plants, with a comparable workspace without plants next to it. At healthcare institutions, living rooms or general areas are equipped with plants. Researchers placed sensors in both rooms to determine the physical differences in the indoor climate. The employees who worked in those areas gave their opinion about the workplace, the indoor climate, the working atmosphere, their state of mind, well-being and health, both before and after placing the plants. Concentration tests were also taken and the cortisol level (a stress hormone) of the participants was determined.
Six positive effects
The study revealed six positive effects that can be linked to the presence of plants in the workspace.
1. Humidity: the relative humidity in rooms with plants is on average about 5 percent higher than in rooms without plants. In winter, up to 17 percent improvement has been measured.
2. Thermal comfort: employees are less likely to experience the temperature in an office space with plants as too hot or too cold.
3. More Attractive: people rate their workplace as more attractive to see after planting (an increase of 26 percent).
4. Mood : the mood of employees is more positive after planting than before. Employees of a company also worry less about their work outside working hours.
5. Satisfaction with performance : employees are more satisfied with their own performance after planting than they were before. This also applies to their expectations about how satisfied the employer is with this performance.
6. Less absenteeism : people who work in a room with plants call in sick 20 percent less often. This amounts to an average of 1.6 less sick days per employee per year.
There will be a follow-up study to further work out the payback period. Tia Hermans: ,,We know that entrepreneurs and employers will only switch to large-scale application of plants in companies if they see a convincing business case. We will now further develop this business case at several locations. In this way, we want to make it more attractive for employers, but also facility services and human resources, to invest in a green indoor climate in the workplace..”
