Potted plants are not only a simple yet decorative element for indoor spaces, adding a natural ambiance to a room, but they also play a vital role in improving indoor air quality.


Research shows that many common indoor plants like aloe vera, spider plants, and ivy can absorb carbon dioxide from the air and remove harmful volatile organic compounds (VOCs) such as formaldehyde and benzene.


Through photosynthesis, these plants release oxygen and filter out certain pollutants, enhancing indoor air quality and positively impacting human health.


By placing different types of potted plants around a room, indoor humidity naturally increases, which is especially beneficial in modern living. Frequent use of air conditioning and heating often makes indoor air dry, which can affect respiratory health.


Plants enhance air humidity through transpiration, creating a more comfortable atmosphere. Large plants such as areca palms and monsteras are particularly effective at increasing humidity, especially in larger rooms where their effects are more noticeable.


Additionally, proper humidity can reduce dust buildup, as moist air helps lower airborne particles, further aiding in maintaining a cleaner environment.


In addition to improving air quality, plant leaves can absorb particulate matter in the air through their structure. Fine dust, smoke, and other suspended particles can be captured and broken down by the leaves, acting as natural "air filters."


Studies indicate that plant root microorganisms also play a role in the purification process, with root microorganisms breaking down certain harmful substances and converting them into nutrients beneficial for the plants.


For example, pothos, with its large, textured leaves and active root system, effectively absorbs and removes impurities in the air, thus purifying the indoor environment.


It's worth mentioning that placing indoor plants can also positively affect mental health. With the acceleration of life's pace and increased work stress, the need for mental relaxation has grown significantly.


Research suggests that seeing green plants can reduce stress, improve concentration, and boost happiness. Adding green plants or small potted plants indoors can bring a sense of tranquility to a busy life, offering a touch of connection to nature.


Moreover, caring for plants—watering, pruning leaves, and general maintenance—serves as a beneficial form of psychological adjustment, helping people to relax and forget their worries.


While potted plants' air purification effect is somewhat limited in certain conditions, combining them with a ventilation system makes the overall effect more significant.


For example, in a well-ventilated room, the oxygen and humidity released by plants can more effectively spread to every corner, notably enhancing the space's air quality. Due to low pollutant concentrations in indoor air, using a variety of plants to decorate the environment can yield better results.


Consider selecting plants that thrive under different lighting conditions. Pairing shade-tolerant and sunlight-loving plants improves air purification effectiveness and adds more variety to indoor decor.


However, there are some important factors to consider when selecting indoor plants. Not all plants are suitable for indoor environments, as some plants absorb oxygen and release carbon dioxide at night, which may affect air quality if too many are placed in an enclosed space.


Additionally, certain plants' leaves or pollen might cause allergic reactions for some individuals, so it's important to consider family members' health and individual sensitivities when choosing plants.


Indoor plants, through a series of physiological and chemical processes, can effectively improve air quality, increase humidity, remove some harmful substances, and help people relieve stress while enhancing their sense of well-being.


With a thoughtful combination of various plant species and appropriate ventilation, potted plants can serve as natural air purifiers, bringing a healthy, refreshing atmosphere to indoor spaces.
