In the hot summer, although air conditioning in the living room can cool down the room, closing the doors and windows blocks air circulation. Therefore, raising some ‘functionally complementary’ flowers in the living room can act as ‘air filters’. Most flowers undergo photosynthesis during the day, absorbing carbon dioxide and releasing oxygen, while respiring at night, absorbing oxygen and releasing carbon dioxide. On the contrary, plants like Cacti and Sedum do the opposite. Raising ‘functionally complementary’ flowers in the same room can both balance the content of oxygen and carbon dioxide in the room and keep the indoor air fresh. 

According to the introduction, Narcissus, Mirabilis jalapa, Chrysanthemum, Celosia, and other flowers can convert nitrogen oxides into proteins, thus eliminating toxicity. Spider plants, Aloe vera, and Sansevieria can absorb a large amount of formaldehyde and other pollutants indoors, eliminating and preventing indoor air pollution. Especially the spider plant, placing a pot in the living room, within 24 hours, its leaves will ‘eat up’ harmful gases such as carbon monoxide in the indoor air, and its effect is even better than an air filter. Plants such as Michelia, Orchid, Syringa, Cactus, and Zamioculcas can effectively purify the air.

Camellia can resist the damage of harmful substances such as sulfur dioxide, and Wisteria has strong resistance to toxic gases such as sulfur dioxide, hydrogen chloride, chlorine, and hydrogen fluoride indoors. Plum trees have the ability to monitor the pollution of sulfur dioxide, hydrogen fluoride, hydrogen sulfide, ethylene, benzene, aldehydes, and other substances in the environment. Once there are sulfides in the environment, spots will appear on its leaves, and even wither and fall off. It should be pointed out that the functions of plants are limited, and their effects increase with the increase in the number of plants. It is impossible to completely rely on indoor plants. Therefore, it is necessary to open the windows frequently to allow air circulation. 

In addition, experts also remind specially: Do not treat the living room as a ‘flower room’ in summer. With too many flowers and trees placed inside, the indoor ventilation is limited, and the thinness of the air will be as if on a plateau. Especially at night, most flowers will release carbon dioxide and absorb oxygen, competing with people for oxygen. Moreover, since most living rooms are sealed at night, along with the carbon dioxide from the soil in pots, human and pet respiration, the concentration of carbon dioxide will increase, causing oxygen deficiency in the human body and affecting health, which will have the opposite effect.
