With the increasing intensity of air pollution, indoors will not be able to avoid the harm of air pollution, how to purify indoor air in daily life?
Can green plants adsorb indoor air pollutants?
Growing more green plants at home and relying on them to adsorb air pollutants can solve the problem of indoor pollution. Green plants have a certain purification function for certain gaseous pollutants in indoor air, which has been confirmed by experimental research and practice.
For example, green plants such as aloe vera, hanging basket, tiger tail orchid, ivy, iron tree, orchid, osmanthus flower, and plum can absorb toxic chemicals; while roses, osmanthus flowers, violets, jasmine, lemons, roses, caryophyllum, bell orchids, purple weeds and other green plants have a certain bactericidal effect.
But greenery is not a panacea. Their adsorption effect on particulate matter is very limited, and their purification effect depends on specific conditions. For example, the number of green plants, the types of pollutants, etc., just like air purifiers, it is necessary to replace the filter element regularly. Any adsorbent has a saturation period, for a pot of flowers, its ability to absorb, decompose and transform polluting substances is also limited, and it is impossible to operate indefinitely.
Which green plants are suitable for indoor placement?
It is also an indisputable fact that green plants will compete with people for oxygen to a certain extent at night. Therefore, indoor placement of green plants should be appropriate, and it is recommended to put some cacti and other succulents native to tropical arid areas at the same time, these succulent green plant fleshy stems have stomata "closed during the day, open at night", which can absorb carbon dioxide while producing oxygen, so that the negative ion concentration in the indoor air increases and improves the oxygen content of the environment.
And due to fertilization and other reasons will also bring additional pollution. At the same time, green plants sometimes grow some insect pests and microorganisms, which shows that green plants will bring some negative effects while purifying the air. Therefore, raise green plants in moderation.
In the final analysis, green plants can only be used as a means of purifying indoor air, and it is an auxiliary means, and it is definitely not a substitute for window ventilation to supplement fresh air.
