In addition, formaldehyde purifier has a certain effect on formaldehyde, but the effect is small and not so perfect.
What is the principle of purifier in addition to formaldehyde? Next, experts from Beijing in addition to formaldehyde Company will seriously answer your questions:
The air purifier sucks in polluted air and discharges it through the internal filter. According to the power of the fan and the spatial arrangement of the filter screen, if the wind is too strong, the air discharged through the filter screen will still have pollutants. Air is inhaled again and passes through the filter screen to eliminate pollutants to the maximum extent. Under the condition of airflow and ventilation, the in addition to formaldehyde function of the purifier is basically useless, and it becomes an incompetent purifier to a great extent. Due to natural ventilation, air flows. The air that may be inhaled into the purifier is taken out of the room by the fluidity of natural ventilation when it is discharged from the evolutionist, that is, the function of the purifier is zero.
In principle, air purifiers can be divided into two types, one is passive adsorption filtration air purifier. The other is the principle of active air purification.
1. The principle of passive adsorption filtration for air purification.
Passive air purifier mainly uses a fan to suck air into the machine, and then filters the air through the built-in filter screen, which can be used for filtering dust, odor and disinfection. HEPA filter+activated carbon filter+photocatalyst (cold catalyst, remote catalyst)+ultraviolet disinfection+electrostatic adsorption filter are used to treat air.
Is the purifier in addition to formaldehyde useful? Experts from Beijing in addition to formaldehyde Company will tell you.
2. Active air purification principle
The principle of active air purification is different from that of passive air purification, that is, the active air purifier gets rid of the restrictions of fans and filter screens, and does not have to wait passively for air to be sucked in and then filtered by fans. But through the characteristics of diffusion sterilization in the air, it can reach every corner of the room effectively and actively, and purify the air without dead ends.
Many merchants exaggerate the effect of purifiers on formaldehyde when promoting their own purifiers. In the process of absorbing other foreign substances, some formaldehyde molecules in the air can also be absorbed, but it is difficult to achieve the professional effect of advertising. On the other hand, formaldehyde can not be effectively decomposed by adsorption, so it is difficult to continue adsorption after the activated carbon filter is saturated, which may cause "secondary pollution". In order to achieve the ideal advertising effect, experts from Beijing in addition to formaldehyde Company told everyone that in addition to formaldehyde suggested looking for a professional in addition to formaldehyde company. If you are not in a hurry to move in, you'd better keep ventilation at all times. After two summers, through professional formaldehyde testing institutions, formaldehyde can only be admitted after reaching the national standard. Try to choose better materials when decorating, such as some particleboard and density board, not too much. If you are eager to move in and want to meet the formaldehyde standard, only a professional in addition to formaldehyde company can move in after professional management and re-inspection.
