Generally, good quality air purifiers can not only purify second-hand smoke, but also effectively filter and decompose air pollutants like formaldehyde, PM10, PM2.5, allergens, tvoc, haze, mold, odor, dust mites, pollen cotton, pet hair, etc.

Definition of second-hand smoke

Secondhand smoke, also known as passive smoking and environmental tobacco smoke, refers to a mixture of smoke released from the burning end of cigarettes or other tobacco products and formed by tobacco smoke exhaled by smokers.

Usually, there are two main types of second-hand smoke: smoke and smoke smell. Smoke is a solid pollutant; the smoke smell is a gaseous pollutant. Studies have pointed out that second-hand smoke contains more than 4000 harmful chemicals and dozens of carcinogens such as tar, ammonia, nicotine, suspended particulates, PM2.5, and polonium-210.

The national standard definition of air purifier

China revised and promulgated the national standard "Air Purifier" in 2015, the standard number is GB/T18801-2015. The revised standard defines air purifiers as: household and similar electrical appliances that have a certain ability to remove one or more pollutants such as solid pollutants, gaseous pollutants, and microorganisms in the indoor air.

It is worth noting that both the removal of one type of pollutant and the removal of multiple types of pollutants can be air purifiers. Therefore, if we really plan to get an air purifier, we must ask the merchant for a third-party test report.

for example:

· (1) Solid pollutants (haze, pollen cotton wool, pet hair, dust, etc.);

· (2) Gaseous pollutants (formaldehyde, tvoc, second-hand smoke, odor, etc.);

· (3) Microorganisms (molds, dust mites, bacteria, coronaviruses, etc.);

Usually, when we evaluate and analyze multi-product air purifiers, we can analyze and judge from three major dimensions, such as:

1. Purification methods and principles, including but not limited to negative ion purification technology, catalyst purification technology, amino acid purification technology, activated carbon adsorption technology, electrostatic purification technology, etc.

2. Inspection and test reports, including but not limited to China Metrology Accreditation Mark CMA, Laboratory Accreditation Mark CNAS, International Mutual Recognition Test Mark ILAC-MRA, etc.

3. Relevant performance parameters, including but not limited to CADR value, CCM value, silent noise, use area, light handling, special functions, rated power, etc.

The portable air purifier is a kind of air purifier, it is suitable for more scenarios than the air purifier in a large space, such as: new decoration in the company office, small study/bedroom/dressing table/dorm room, dining table /Children's room/pet room/elderly room/bedside use...

However, the relevant performance parameters of the portable air purifier will be lower, such as CADR value, CCM value, use area, etc.

In principle, the higher the relevant performance parameters (such as CADR value, CCM value) of the air purifier, the higher the purification efficiency. If parents want to remove air pollutants faster and more efficiently, they can also consider an air purifier with a high CADR value and a high CCM value. Of course, we must also consider whether there is a third-party test report and the principle of purifier purification.

Here I recommend a portable air purifier with a high appearance and high performance:
