Is the car air purifier is “black technology” or “pseudo-technology”? The real assessment of the Consumer Protection Committee tells you the truth

Particulate purification performance and gaseous pollutant purification performance test

Clean air volume and purification efficiency is two common indicators for evaluating air purifier purification performance. Simply, the larger the value of clean air (CADR), the faster the purification speed, when the value is less than 1, the description performance is weak. When the purification efficiency value is less than 5%, the performance is low.

Based on these two indicators, we were tested for 20 samples of the three types of purification function of the main particulate matter purification, formaldehyde purification and TVOC purification function. Due to the difference in material, technology, 20 sample purification performance, some samples The key performance parameters are not marked, false, and even suspected of false or exaggerated.

Particle purification performance:

6 pieces of sample “divided into particulate matter” performance significant

The source of particulates in the air in the vehicle is mainly infiltrated into the atmospheric particulate contaminants and car exhaust gas in the car.

The product claimed to purify PM2.5 (fine particles), smog, dust, dust, pollen, cigarette (second-hand smoke), etc., can be classified as particulate purification performance.

We test 18 products claimed to have particulate purification performance.

Among them, 6 samples were significant, and 30 minutes purification efficiency reached 90% and 1 hour purification efficiency reached 99%.

Another sample has a very weak performance, clean air volume and purification efficiency are less than the detection lower limit, and the purification effect is close to natural attenuation.

TVOC purification performance is generally not high

Gaseous pollutants such as formaldehyde, TVOC, etc.

We have discovered that 1 product and 7 of the declared formaldehyde purification performance have been discovered after the products with TVOC purification performance.

1 sample performance is remarkable, 30 minutes purification efficiency reached 90% and 1 hour purification efficiency reached 99%

Key parameters are not marked,

We have contracted that most samples have only a clean performance, and the key parameters are not marked.

In the sample declared in 18 samples, 10 pieces were not nominally cleaned with clean air volume or purification efficiency parameters;

16 pieces declared a sample of formaldehyde, 9 were unconscious;

15 pieces declared that 9 were not marked in the samples of the bacteria.

Another key performance parameter virtual standard for 2 samples, does not meet the relevant standards, “90% of the measured value is not less than the nominal value”,

The measured value and the nominal value are 60%

The parameters of other samples meet this requirement.

At the same time, the merchant is suspected of false or exaggerating publicity in order to highlight its own product advantages.

If there are 5 pieces of clean air volume <1 m3 / h and 1 hour purification efficiency <5%, 4 products of TVOC clean air volume <1m3 / h and 1 hour purification efficiency <5%, very low measured value) The purification efficiency of the sample is close to natural attenuation, and the corresponding purification performance is negligible. The purification effect used in the actual environment can be seen.

in summary,

The excellent players in this comparative trial are as follows!
