How to buy air purifier air purifier technology original

With the progress of society, people's living standards have been significantly improved, but the environment is no more than before, and now the air pollution is getting more and more serious, so many people think of buying an air purifier, then follow the small Let's take a look at how to choose the air purifier and air purifier technology.

How to buy an air purifier

1. Select the air purifier according to the size of the space. If you are in a large area, the air purifier should be selected as large as possible. This can be judged and selected through product introduction.

2. Consider the safety of the air purifier. The air purifier's casing, movement and purification technology are related to the safety of the air purifier. Purification techniques are best like positive and negative ions in nature.

3. Pay attention to the principle of the air purifier. The purification principle mainly includes: physical mode, electrostatic mode, chemical mode, negative ion mode and composite mode. In general, the purification effect using multiple purification principles at the same time will be even better.

Air Purifier Technology Principle

Passive adsorption filter air purifier principle

The passive air purifier mainly uses a fan to pump air into the machine, and then filters the air through the built-in filter to filter dust, odor and disinfection. Filter air purifiers mostly use HEPA filter + activated carbon filter + photocatalyst (cold catalyst, far catalyst) + ultraviolet disinfection + electrostatic adsorption filter to deal with air. The HEPA filter has the function of filtering dust particles, and the substances such as activated carbon mainly adsorb toxic and harmful substances such as odor.

Active air purifier principle

The principle of active air purification differs from the principle of passive air purification. The active air purifier is free from the limitations of the fan and the filter. It is not necessary to wait until the air is pumped in and then filtered and then discharged through the fan. Effective and active release of purification and sterilization factors into the air, through the characteristics of diffuse and diffuse in the air, to achieve the effect of no dead angle purification of air in all corners of the room.

Comparison of two purifier principles

Compare the efficiency of air purification. Passive adsorption purifier adopts fan + filter mode for air purification. The principle of using air flow alone will inevitably have dead angles. Therefore, passive air purifiers can only place a small space in the air purifier to produce certain Purification effect, only after a long time is passed before the indoor air can be completely filtered.

The active air purifier utilizes the diffuse nature of the air to spread the purification factor to all corners for air purification, so that the air can be purified in a place where it can be diffused. Comparing with the negative ion air purifier, it is found that after the negative ions are released from the air, the negative ions can actively attack, find the pollutants in the air, and agglomerate into a group to actively settle them. From this point of view, active air purification has obvious advantages.

After reading this article on how to choose the principle of air purifier and air purifier technology, do you have a certain understanding of it? I hope to help you.
