Filter H11 for purifier P30 SLK, Alecoair

The 3 in 1 filter (Pre-filter, TRUE HEPA filter and Active Carbon filter) for the AlecoAir P30 SILK purifier:
The pre-filter retains large particles of dust, lint or animal hair.
The TRUE HEPA filter retains microparticles of dust, mites, pollen, mold spores, bacteria and viruses. The TRUE HEPA filter retains particles over 0.3 microns in a proportion of over 99.97%.
The Active Carbon filter removes unpleasant odors (cigarette smoke, the smell of food, etc.), as well as toxic gases.
Recommendation: Change the 3 in 1 filter once every 6 months or whenever you think it is dirty and reduces the efficiency of the device.

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