Is it necessary to use a car air purifier?
The answer is yes!
After the Industrial Revolution, many areas of the world vigorously developed heavy industries, leading to plummeting air quality, posing a serious threat to human health, including the famous "Los Angeles Photochemical Smog Incident."
In order to improve air quality, in addition to promulgating long-term air treatment policies, many scientific research institutions are also actively developing air purification technologies to provide consumers with a healthy breathing experience in the first time.
Of course, these technologies were not initially adopted in cars. After a long period of conceptual change, when people realize that the air in the car is also seriously polluted, the car air purification technology specifically for cars has gradually gained attention.
Many countries have strict controls on the air quality in cars. In this regard, on March 1, 2012, my country also issued the "Guidelines for Evaluation of Air Quality in Passenger Cars". The release of the guidelines has greatly promoted the development of in-car air purification products in China. Not only domestic brands, many well-known foreign brands have also landed in the Chinese market.
At present, there are mainly the following categories of car air purification
1: Add essential oil and spray perfume to cover the peculiar smell in the car.
In this way, the air will improve in the short term, but the work is done in the way of covering. In essence, it does not deal with the source of odor. In addition, scientific common sense, the smell of things is harmful to the human body, and the market is full of dazzling arrays. It is recommended to use it with caution.
2: Activated carbon + filter screen adsorption
Activated carbon has an obvious effect on the adsorption of formaldehyde and odor. The effect is more and less directly related to the amount of activated carbon put in the purifier. The disadvantage of this method is that the activated carbon and filter need to be replaced frequently, otherwise it will easily cause secondary pollution Even worsening pollution.
3: Negative ion purification + filter screen adsorption.
This type of product generates electrostatic negative ions through a negative ion generator, grabs the peculiar smell and harmful positive ions floating in the car, and then adsorbs it through the filter. The disadvantage of this method is that the filter needs to be replaced frequently, otherwise it will easily cause secondary pollution Even worsening pollution.
4:: Super oxygen (ozone) air purifier
The super oxygen (ozone) air purifier is the latest black technology on the market. It uses super oxygen molecules to decompose formaldehyde and quickly and completely remove formaldehyde. In addition to removing formaldehyde, it can also kill more than 99% of the common germs on the market. In addition to new houses and new cars, it can also be used to remove second-hand smoke and keep fresh in refrigerators. It has no secondary pollution and no consumables. It is very economical and practical. But when using this type of car air purifier, pay attention to the concentration of super oxygen (ozone) in the cabin, because if the concentration of super oxygen (ozone) is too high, a small number of people will be more sensitive. Once you find uncomfortable, you should turn off the machine , Open windows for ventilation.
