Fresh air system over the effective filter PM2.5?
Effective solution to the purification of PM2.5, due to the use of ozone does not produce two-stage high-voltage electrostatic dust grille to replace the traditional media filter (HEPA), and a cleaning reminder, free replacement, just neutral soap Water can be cleaned.
And with such a high efficiency filter such as the new fan, the design and construction of a very high demand, or high speed, high static pressure generated by the noise can not be avoided (muffler measures need to muffler outside the box also calculate the flow And the wind speed is reasonable).
PM2.5 refers to particles of less than or equal to 2.5 microns in the atmosphere (very, very small).
Fresh air system (equivalent to the outdoor air sent in, indoor air to send out) should not be able to filter.
