Are the home used HEPA filter air purifiers useful in summer?

In the hot summer, wherever it is cool, we just want to stay there! Fans, air conditioners, WIFI, and watermelons have become our summer standard!

Wait, what about air purifiers?


What? Stop kidding, I just use the air purifier to purify the indoor air in smoggy days or after the new house is renovated. Summer is here, the smog is far away, and the house has been renovated for a long time. The air purifier is useless!


OLANSI is going to say no to this statement. We all know that air purifiers are not only for preventing smog, they can also remove indoor pollutants such as formaldehyde, benzene, and ammonia, but did you know? In summer, the indoor air environment can be worse than winter!

Why this?


First, in summer, the temperature is high and humid, and the release rate of indoor pollutants such as formaldehyde, benzene, ammonia and other harmful substances will also be greatly increased. For furniture in the home, pollutants are not released in a short time (it may take up to 15 years to be completely released).


Among them, formaldehyde, known as “the first indoor killer”, is more active in spring and summer than in winter. It is because the volatilization point of formaldehyde is 19°C. When the temperature is higher, the intensity of volatilization is greater. For every degree of temperature rise, the concentration of formaldehyde will increase by 0.4 times, especially in summer when the temperature rises, the release will be more intense. , and the concentration may be 3 times higher than normal.


This is why many people have encountered confusion: my house has been renovated for several years, and the pollutants have not been dissipated. In summer, I can smell a pungent odor.


Second, the weather is hot in summer. As one of the standard configurations in summer, the air conditioner at home naturally runs for a long time. However, when the air conditioner is generally turned on, the doors and windows are tightly closed, the air circulation is naturally poor, and the convection between the indoor air and the outdoor air is reduced. Naturally, pollutants released by furniture cannot be effectively diffused. And the long-term closed indoor environment will also cause various discomforts such as “air conditioning disease” to the human body.


Third, in summer, the body’s own metabolism and the volatile components of various domestic wastes will also increase, which will make indoor air pollution even more serious. The indoor environment monitoring center has done environmental inspections on homes and office buildings, and found that indoor air pollutants in summer are more than 20% higher than other seasons.


Fourth, the humid and high temperature environment in summer is also a “hotbed” for the proliferation of microorganisms. A survey shows that 21% of indoor air quality problems are caused by microbial pollution, which mainly includes bacteria, fungi, pollen, viruses, etc. In addition to directly entering our body, these germs may also pass through attachment to tiny particles, The dust enters our body and causes harm to our body.

After reading these, are you still wondering whether it is necessary to buy an air purifier in summer?
