    Hospital air purifier is divided into fiber filtration, activated carbon adsorption, catalyst, electrostatic dust removal, plasma technology, etc. according to the purification principle. Different purification technologies should be used for different pollutants, such as: fiber filtration, electrostatic dust removal and plasma technology should be used to remove PM2.5; activated carbon adsorption, catalyst and plasma technology should be used to remove formaldehyde and benzene; catalyst should be used for bacteria removal With plasma technology. Hospital air purifier currently on the market generally uses a combination of multiple purification technologies.

    Important indicators when purchasing hospital air purifier:

    01. Clean air volume (referred to as CADR)
    CADR is the volume of clean air produced per unit time and is the core performance index of air purifiers. The larger the CADR value, the faster the purification rate.
    02. Applicable area
    The applicable area is obtained by multiplying CADR by the corresponding coefficient (0.07-0.12). Taking CADR400 as an example, the usable area is 28-48 square meters.
    03. Cumulative purification capacity (CCM for short)
    CCM represents the life of the filter. The larger the value, the longer the filter replacement cycle and the lower the replacement frequency. For electrostatic purifiers, CCM is not a replacement cycle, but a cycle to clean the electrostatic module.
    04. Noise
    In the case of the same CADR, a purifier with low noise is preferred.
    05. Release of harmful substances
    Air purifiers that use electrostatic dust removal or plasma purification technology are prone to produce ozone. Such air purifiers should ensure that the ozone emission reaches the standard.
    06. Microbial removal
    The microbial removal function of the hospital air purifier is very helpful for the young and old with poor resistance. In a humid environment, the antibacterial and antifungal function can also reduce the growth of microorganisms on the hospital air purifier and avoid secondary pollution.
