The air purifier has a certain purification effect on air impurities, but it does not have the ability to completely purify it, because it cannot circulate the air in the entire set of rooms, such as two rooms, one hall and three spaces, but can only circulate air in one space for purification.
For example, when someone passes by, they will feel the wind caused by the air flow. If the two people are far away, they will not feel the wind.
The air purifier can only make local air flow, so it can only be partially purified. Therefore, air impurities such as particulate matter (such as PM2.5) and decoration pollutants (such as formaldehyde) of 0.3 microns and above in the air cannot be completely removed.
So within the purifying range of air purifiers, can air impurities be solved? Air purifiers can solve particles in the air of 0.3 microns and above, but cannot solve decoration pollutants in the air.
The direct reason is that the purification rate of most air purifiers is less than the volatilization rate of decoration pollution sources. The fundamental reason is that the air purifiers do not solve the volatilization source of gaseous decoration pollutants.
