The smaller the micron size, the more efficient the filtration system needs to be to capture and remove these particles from the air. Some common examples of particles and their approximate micron size are: Dust and pollen: 1-100 microns; Bacteria and mold spores: 0.3-10 microns; Smoke and combustion particles: 0.01-1 micron

ادامه مطلبWood Smoke: The size of these particles varies from 0.05 to 1 micron, categorising them as submicron particles. Dust Mites: Measuring 10-25 microns, dust mites are considered fine particles. Mould Spores: With sizes between 3-30 microns, mould spores fall into the acceptable particle range.
ادامه مطلبThe nominal micron rating indicates the ability of a filter to retain a nominal amount, or remove a minimum percentage (usually 50-90%) of material, of the rated pore size. Absolute filters are made to have a more regular pore size. The absolute micron rating indicates the maximum pore or opening size of the filter medium.

To put these sizes into perspective, fine sand will slide through a 250-micron filter, whereas a 37-micron size filter will allow pollen grains through. The final micron size for trichomes to safely pass through is 20-25.
