How does an air purifier work?
The air purifier sucks in the dirty air and removes it after passing through the internal filter. According to the power of the fan and the space arrangement of the filter, if the wind is too strong, there will still be pollutants in the air discharged through the filter. Inhaled air, through the filter, in order to maximize the elimination of pollutants. When the air is flowing and the windows are opened for ventilation, the aldehyde removal function of the purifier is basically useless, and it has largely become an incompetent vacuum cleaner. Because of natural ventilation, the air is flowing. Maybe the air sucked into the purifier, when it is discharged from the evolution device, will be taken out of the room by the fluidity of natural ventilation, that is, the function of the purifier will be zero.
Therefore, the function of the purifier will only be effective in a closed environment with poor air flow. Only then can the purifier purify the air repeatedly and clean the air through the filter.
The 99.99% formaldehyde removal rate advertised by the purifier is to work in a confined space and repeatedly clean the air. After a period of time, the formaldehyde concentration drops sharply.
Only by letting the purifier clean the same piece of air repeatedly can the purpose of purifying the air be achieved. Otherwise, once it is in the case of natural ventilation, the air cleaned by the purifier is not the same piece of air, and it may be sent out of the room just after cleaning.
