Does plants really purify indoor air ?

2020-12-02

Many people grow plants not to purify the indoor air, but to make the home look more natural and warm. From a scientific point of view, the ornamental nature of plants indoors is the most important, and their ability to purify the air is negligible.

I have been seeing some reports before that, NASA studies have shown that plants have a good ability to purify the air, including the common green dill, sylvestris, monstera and tiger pilan, etc., which have an impact on indoor air. It has a very strong air purification effect, can absorb harmful gases in the room, and increase the oxygen content in the room.

I am not think this research is wrong, but they are doing experiments in a closed laboratory environment, and our living environment is more complicated, to be honest, we often need to open windows for ventilation to achieve good purification. The air effect is far better than closing the window and letting plants purify the air.

Many studies have shown that in a confined environment, indoor plants have better levels of air pollutants and released oxygen. Some plants are poisonous, but they can also absorb most of the harmful substances in the room and will continue to release oxygen, such as Evergreen.

One thing everyone needs to understand is that some plants do have a good air purification effect, but this effect is not visible to the naked eye, but rather slow. It can even be said that the air purification ability of indoor plants is not publicized by businesses or media. So good, it is a gimmick, for many novices, it is very rare to be able to feed plants at home.

If you want indoor plants to play a better air purification effect, but also to make them grow stronger, it is best to ensure that there is proper light every day, or a longer time of light exposure, so as to ensure the normal photosynthesis of plants effect.

Plants raised indoors should also pay attention to regular cleaning of the leaves, to ensure proper light, so that the plants grow stronger, and the ability of these plants to purify the air is better.

1. Many factors affecting indoor air quality:

People’s quality of life has begun to improve, and of course they will also pay attention to the quality of indoor air, whether it will affect their health. There are many factors to judge indoor air quality, including the concentration of volatile organic matter, air humidity and ambient temperature. In fact, we only need to detect the indoor PM2.5 concentration to determine the air quality. If you want to detect formaldehyde and VOC (volatile organic compounds) indoors, it is more difficult, and you need some professional instruments to detect them.

Volatile organic compounds are generally released in furniture, including carpets, sofas and various electrical equipment. We can reduce the concentration of indoor volatile organic compounds by choosing some environmentally friendly products.

Second, the role of indoor flowers

Potted plants maintained indoors, as long as they grow healthy, they can absorb harmful substances such as benzene, trichloroethylene, and formaldehyde in the air, and can slowly release oxygen. Of course, the content of harmful gases absorbed by these indoor plants is extremely low . If it is in an open window environment, the effect of plants in purifying the air is almost negligible.

If there is a lot of dust on the leaves of the plant, the air purification effect of the plant is even more compromised.

One thing everyone needs to understand is that plants generally purify the air by reducing a variety of volatile organic compounds in the air. However, the rate at which plants absorb these volatile organic compounds is very slow, which is not enough to have much impact on indoor air quality. Plants remove volatile organic compounds from the air, generally through the absorption of plant branches and leaves, soil microbial removal and root absorption.

If you want to get the best improvement in indoor air quality, a pot of potted plants should be placed at least every few square meters in the house, so that the air can be purified.

But this involves another point. Indoor plants need good ventilation to grow better. However, in the case of ventilation, the ability of plants to absorb harmful gases can actually be ignored, because in the case of ventilation, the indoor air It will be changed every hour or so. The air purified by indoor plants will soon be replaced by outdoor air.

3. Indoor and outdoor air quality

One thing to understand is that for most families, the outdoor air quality is much better than the indoor air quality. This is because in ordinary families, there are many kinds of furniture and daily necessities. These household items will It emits all kinds of harmful volatile organic compounds. When living indoors, the best way to purify the air is actually to strengthen ventilation.

From a long-term perspective, the best way to ensure better indoor air quality and improve air quality is to open doors and windows to increase the speed of air exchange.

Of course, in winter, if the place where they live is relatively cold, in winter many people will close their doors and windows for ventilation much less frequently, which will definitely affect the indoor air quality.

4. Ways to improve indoor air quality

1. Clean regularly

There are many techniques to improve indoor air quality. When walking indoors, shoes will bring some dust and pollutants. It is more important to pay attention to cleaning the home and the floor regularly.

2. Avoid excessive humidity

The indoor living environment should avoid excessive humidity, which is detrimental to people's health, is easy to breed mold, and affects the skin and respiratory tract. Enhancing ventilation and turning on dehumidifier can reduce humidity.

In fact, the indoor air humidity can be maintained at about 40~%60%. If the air is too dry, it will also cause dry skin. If the air humidity is too high, it will definitely affect people’s lives. Maintain a certain air humidity. It is also beneficial to the growth of plants. It is necessary to have a hygrometer at home.

3. Reduce indoor smoke

Whether it is second-hand smoke or oil fume, it will contain some harmful volatile chemicals. If someone smokes in the house, it is best to smoke in the area, otherwise it will have a greater impact on air quality.

5. What are the benefits of growing indoor plants?

Of course, growing flowers indoors has many benefits. Although the air purification ability of indoor plants is limited, it is continuous.

1. Reduce illness and relieve mood

Keeping some potted plants indoors can indeed reduce the risk of colds, coughs and sore throats, and improve people's vitality, which has an indirect effect on people's health.

In fact, this statement shows that plants are effective in alleviating people's mood, making people more energetic, and indirectly reducing the chance of disease.

Just like we usually in the office, we can place more potted plants, which can reduce the chance of illness, and it will relieve people's mood and relieve stress. Planting some plants around people's lives can reduce symptoms such as dry skin and headaches.

2. Plants reduce noise

Plants are a natural sound-absorbing material, and they can reduce indoor noise. Putting some potted plants in the room can indeed provide people with a better living environment and a more comfortable listening environment, thereby reducing stress.

This is why the roadsides are filled with green plants, which actually have the effect of absorbing noise.

3. Plants make people happy

Planting some potted plants at home not only can be viewed, but also can make people feel better, so that we can get satisfaction and happiness in the process of growing flowers.

This sounds a bit mysterious, but most people who grow flowers have lower blood pressure than those who don't. In fact, it can be understood that growing flowers can bring us happiness and reduce our stress.

4. Adjust humidity

Indoor plants can maintain a certain air humidity, especially in a closed indoor environment. It has just been mentioned that the indoor environmental humidity is best maintained between 40% and 60%, which is very suitable for the growth of plants and people's lives.

5. Increase concentration

Raising some plants is also good for people's health and can increase people's attention. For example, placing some potted plants next to the desk can help us concentrate better and improve work efficiency.

to sum up:

Plants have little ability to purify the air, but there are still many benefits of keeping potted plants indoors. As long as you take care of them properly, indoor plants will bring us endless benefits.
