Hepa H13 filter for P14 purifier, Alecoair

This filter consists of 3 layers for an efficient air quality improvement:
Washable Pre-Filter - Retains large particles of dust, lint or pet hair.
TRUE HEPA filter (H13)-Retains microparticles of dust, pollen, mites, mold spores, bacteria and viruses. The HEPA filter captures particles larger than 0.3 microns at a rate of more than 99.97%.
Active Carbon Filter - Eliminates unpleasant odors (cigarette smoke, food odor, etc.) as well as toxic gases.

Precautions:
It is recommended to change the 3-in-1 filter when it is loaded with impurities so as not to affect the performance of the device.
The 3-in-1 filter should be changed every 6-12 months or when:
the HEPA filter changes color and becomes gray or
the appliance emits a heavy odor into the air, as dust and polluting particles are sent back into the room or
the air flow released is uneven, because the impurities accumulated in certain areas of the filter prevent the uniform distribution of air or
the air flow is getting lower, this is due to the particulate loading of the filter which blocks the air flow.
