What is the CCM value?

Measurement of CCM value: When the CADR value of the air purifier decreases to 50 per cent, the total weight of the cumulative purified pollutants (particulate matter or formaldehyde) in mg. Solid pollutants (particulate matter) CCM is expressed as P, and is divided into four levels, and gaseous pollutants (formaldehyde) CCM is expressed as F, and is divided into four levels. This means the amount of formaldehyde or particulate matter that the product can eliminate before the filter is ‘obsolete’.

As a simple example, assuming that the filter used by an air purifier to purify air is a cup, and the particulate matter or gaseous pollutants purified is water, the meaning of CCM is to tell you how much water the cup can hold.

The quantitative level of particulate matter CCM is as follows:

P1: 3000mg ≤ CCM particulate matter <5000mg

P2: 5000mg ≤ CCM particulate matter <8000mg

P3: 8000mg ≤ CCM particulate matter <12000mg

P4: 12000mg ≤ CCM particulate matter (the best).

The quantitative level of formaldehyde CCM is as follows:

F1: 300mg ≤ CCM Formaldehyde＜600mg

F2: 600mg≤CCM formaldehyde＜1000mg

F3: 1000mg≤CCM formaldehyde＜1500mg

F4: 1500mg≤CCM formaldehyde (best).
