Air purifiers are gradually recognized by the society as effective products for improving indoor air quality. More and more families are also choosing air purifiers to maintain indoor air. As a result, there are more and more air purifier brands in the market. The brand of air purifier is similar to the information related to air purifiers, which consumers want to know. As the saying goes, many people are ignorant of air purifiers. Because air pollution has a great impact on health, they have to understand it.
In fact, the components of the air purifier are very simple, mainly composed of a fan power, an air filter and some purification technologies. The working principle is that the fan power in the purifier exerts an extra force on the dirty air, allowing the dirty air to enter. In the air purifier, the filter and purification technology removes and purifies the pollutants in the air, and finally outputs clean and fresh air. The air purifier improves the indoor air quality in this way. From the working principle of the air purifier we do not It is easy to see that the factors affecting the purification efficiency of the air purifier are inseparable from the components of the purifier.
Therefore, in order to judge the deterioration of an air purifier, we must look at the quality of the components inside the purifier body.
First of all, talking about fan power, fan power is the heart of the air purifier, because there is no purifier without fan power, the indoor air pollutants, you can not get the purification technology in the purifier purification, such a purifier Like an ornament, with the development of purifier technology, some active purification technologies have appeared on the market. Although it can actively disperse into the air to capture pollutants, it has no fan power, and its purification efficiency is also Not perfect. As the fan power effect of the air purifier, the most powerful is the double-power centrifugal fan, which has low power, low noise and strong power. It has a direct relationship with the CADR value, energy efficiency value and noise value in the new national standard of the air purifier.
Secondly, we say the filter of the purifier, the filter of the purifier in the market can generally be divided into layers, the first layer is the pre-filter, which is mainly to remove the dander, hair and dust in the air; The second layer is activated carbon filter. The activated carbon filter has a very strong purifying effect on air odor, such as formaldehyde, tvoc, organic volatiles of household building materials; the third layer is HEPA filter, HEPA filter is air purifier The key filter layer is able to filter out the residual contaminants in the air filtered by the first two layers of filters, which can filter out 0.3μm of material. Of course, some air purifiers in the market also have humidifying filters, which are developed for the dry climate. The humidifying filter and the HEPA filter are similar in nature, but its adsorption to water is also relatively strong. These filters are the most critical for purifiers to remove pollutants. Therefore, their selection is also very important, because the effect of different materials on the filter to filter pollutants is different, such as the best recognized in the current air purifier industry. The HEPA filter material is an antibacterial peptide HEPA filter. ?
Finally, it is the active technology in the air purifier. The so-called active technology of the air purifier is to use the physical or chemical principle to create some technologies that purify the air in the purifier, such as ozone sterilization technology, electrostatic dust collection technology, Negative ion purification technology, etc. However, after the user experience, many active technologies have been verified to have certain hidden dangers. For example, ozone sterilization technology, if the ozone generator is not designed, the user will release excessive oxygen at the time of use. This will not only prevent the health from being activated, but will cause the purifier to harm its own health. With the improvement and improvement of the active purification technology of the air purifier, the mainstream active purification technology of the air purifier has been confirmed, that is, the negative ion purification technology, the negative ion purification technology, is to let the purifier release an appropriate amount of negative ions into the air, thereby causing negative ions. The deposition and purification of pollutants in the air, negative ions are very effective in improving air quality, because negative ions are considered to be "air vitamins", and the negative ion content in the air has a huge impact on air quality.
Through the above explanation, we have chosen the air purifier from these details to judge the air purifier is very helpful to choose a practical air purifier.
