商用空气净化设备要比家用净化器门槛高很多，虽然商用空气净化设备门槛较高，但其评判依据不外乎“三高一低”，CADR值（洁净空气量）高、CCM（累积净化量）高、净化能效高、噪声低。

Commercial air purification equipment is much higher than the domestic purifier threshold, although commercial air purification equipment, higher threshold, but the criterion is nothing more than "three high and one low", the value of CADR (clean air), CCM (cumulative amount of purified high purification), high efficiency, low noise.

洁净空气量（CADR）

Clean air volume (CADR)

洁净空气量（简称CADR）：空气净化器产生“无特定污染物”的洁净空气的速率，以立方米每小时（m3/h）为单位。

Clean air (referred to as CADR): the rate at which air purifiers produce clean air with no specific pollutants, in cubic meters per hour (m3/h).

洁净空气CADR值越高，空气净化器净化能效越强，在选购空气净化器时CADR值是首要考虑的因素。

The higher the CADR value of clean air, the stronger the purification efficiency of air purifiers, and the CADR value is the primary consideration in the selection of air purifiers.

备注：适用面积=CADR值*（0.07～0.1）。

Remark: applicable area =CADR value * (0.07 ~ 0.1).

累积净化量（CCM）

Cumulative purification capacity (CCM)

累积净化量（简称CCM）：空气净化器的CADR降低至初始值的50%时，累计净化掉的污染物的质量，以毫克（mg）为单位。

Cumulative purification (referred to as CCM): when the CADR of the air purifier is reduced to 50% of the initial value, the quality of the accumulated pollutants is reduced to Mg (mg).

累积净化量CCM反应使用寿命

Cumulative purification capacity; CCM reaction; service life

累积净化量CCM是往往反应的是滤网使用寿命，数值越大，滤网更换的频率越低。

Cumulative purification capacity CCM is often the reaction screen life, the greater the value of the screen, the lower the frequency of change.

备注：颗粒物CCM从低到高分为P1到P4四个等级，市场上商用空气净化设备CCM普遍是P2-P3。

Remarks: particulate CCM from low to high P1 to P4 four grades, the market for commercial air purification equipment CCM is generally P2-P3.

净化能效（η）

Purification efficiency (ETA)

净化能效（η）：空气净化器单位功耗能产生的洁净空气量，以立方米每小时瓦（m3/( W•h)）为单位。一般情况下，数值越大表示净化器既节能，净化效果又好，是消费者的首选产品。

Purification efficiency (ETA): clean air volume air purifier unit power can be generated, in cubic meters per hour (w m3/ (W - H) as a unit). Under normal circumstances, the greater the value of the purifier, both energy saving, purification effect and good, is the preferred product of consumers.

空气净化器产品净化效果的好坏关键在于过滤网性能。通常使用的高效过滤器对粒径在0.3μm的粒子可达到99.99%的拦截效率。

The key to purifying the air purifier is the performance of the filter. The commonly used HEPA filter can achieve a 99.99% interception efficiency for particles with a particle size of 0.3 M.

备注：市场上空气净化器能耗普遍为2-6[m3/( W•h)]。

Remarks: the energy consumption of air purifiers in the market is generally 2-6[m3/ (W • h)].
