Plants for a healthier living

The side effects and dangers of air pollution are commonly known by the general public. However only a minority understands that indoor air pollution is at least 10 times higher than the outdoor, as shown by a research. Through experiments, it is proven that indoor gardening can effectively reduce or eliminate indoor air pollution.

Indoor sterilization

Plants absorb the toxic gasses, lampblack and radiation at home. Indoor plants help enhance ventilation and eliminate odour. A research by NASA shows that an indoor plant can eliminate 90% of formaldehyde in one cubic meter space. (Formaldehyde is commonly found in furniture, cigarettes, cosmetics, clothing and others. Pollution of formaldehyde can cause skin disease, skin cancer, discomfort of eyes, nose and throat, emotional instability, memory loss etc.)

Reduce indoor dust & micro-organism
Cilium, hair and mucus on plants are able to absorb the dust in air. Vapour from leaves through the process of respiration helps to increase moisture level and reduce room temperature. When dust integrates with vapour, the weight of that combination increases and causes the dust to subside. Thus, it is able to reduce the amount of dust in the air. Studies show that indoor planting reduces 20% to 70% of dust.

Ensure good indoor air ventilation
Carbon dioxide (CO2) released by plans at night is only 20% of the volume plants absorb in the day time. This shows that plants release a small amount of CO2 at night and it is not harmful to our health. However, there are some plants that absorb CO2 and release oxygen at night, such as the cactus and Sansevieria. These plants if place indoor will help regulate indoor air ventilation. -Baba
