When it comes to air purifiers, I believe everyone will reflexively think of smog and PM2.5;

     Air pollution is not limited to PM2.5

If you think that air pollution only refers to the hazy haze, then you are too naive. Haze is indeed terrifying, mainly because PM2.5 can directly enter the bronchi and even the lungs through the respiratory system, becoming the primary culprit of respiratory and cerebrovascular diseases.

Authoritative data shows that the direct and indirect mortality rate caused by smog is as high as 0.9 ‰ per year, which is significantly higher than the 0.7 ‰ mortality rate caused by smoking and the 0.09% mortality rate caused by traffic accidents.

However, the toxicity of formaldehyde cannot be ignored. It cannot be seen but can be smelled, covering a wider range and can cause certain irritation to the skin and mucous membranes. When the indoor formaldehyde content exceeds a certain concentration, people will feel significantly uncomfortable. Formaldehyde concentrations greater than 0.08m ³ can cause redness, itching, discomfort or pain in the throat, hoarseness, sneezing, chest tightness, asthma, dermatitis, etc.

In addition, there are many other pollutants in the air, mainly divided into: first, particulate matter exceeding the standard, in addition to the most familiar PM2.5, there are also allergenic pollen, bacteria, viruses, pet hair, etc; The second issue is that volatile organic compounds exceed the standard, such as formaldehyde, as well as second-hand smoke and odors.

     The functions of the purifier are far more powerful than you imagine

Since it is called an air purifier, as the name suggests, there are actually many things it can do besides purifying PM2.5.

Firstly, it is necessary to have a set of useful and practical primary filters that can filter the air layer by layer and remove large particles such as hair, dust, oil fumes, etc.

Secondly, in order to purify inhalable particulate matter in the air, air purifiers use physical filtration technology to filter out pollen, cigarette smoke, bacteria, and other substances in the air. In order to purify and adsorb harmful substances more quickly, professional motors with high air volume are also essential! It can make a large amount of air pass through the filter element faster and quickly filter out harmful substances.

The new home has just been renovated or new furniture has been added, and there is no obvious odor, but formaldehyde with a release period of 3-15 years will always exist. You need to turn on an air purifier that can remove formaldehyde.

During autumn and winter festivals, there are many gatherings with friends and family, and it is inevitable that some people will smoke. In order to reduce the harm of second-hand smoke to more people, especially children, you need to turn on an air purifier that can effectively absorb bacteria and smoke.

Spring and summer are the peak seasons for allergies and colds. If there is a pregnant woman and a young child at home, what should be done for cross infection? You need to turn on an air purifier that can kill bacteria and eliminate allergens.
