1. Primary lter screen:
The cleaning frequency of the primary lter screen should be determined according to
the air speed, air pollution degree and cumulative operation time of product operation.
It should normally be cleaned once normally for 2-3 months. Please clean it in time,
otherwise the purication eciency of the air purier will be aected.
2. HEPA composite lter screen:
The multifunctional composite lter, which is composed of the
HEPA, the adsorption and purication material, the catalytic
purication material and the functional lter material, can
eectively purify the suspended particles, virus and bacteria in the

Safety precautions
When humidity in the room is very high, the air quality sensor may form condensed water. In
this case, in the AUTO mode, even if the air quality is good, the status light on the panel will
show poor air quality. It is recommended that you manually select the air volume.
Precautions
Do not contact the power plug with a wet hand.
Do not use other forms of power. Only AC220V50HZ can be used as power
source. The user must not open the case for maintenance. The maintenance
must be operated by professional maintenance personnel. Do not pour water or
liquid or ammable cleaning agent into the product so as not to cause damage
to the product or cause re due to electric shock.
Do not clean the body with solvents or chemical liquids in order to avoid
corrosion of the body. Do not place the hand or any object into the air outlet.
Do not pull the power cord from the power supply. The plug should be removed
safely by holding the power socket. Do not place any articles at the air inlet
and outlet, so as not to aect the ow of the air and reduce the purication
eciency.
Make sure to disconnect the power supply before cleaning the machine.
In the operation, the back of purier should be kept 20cm away from the wall,
and over 30cm on both sides. Place the product in a dry and smooth horizontal
plane and keep it away from heat source and too wet location.
Remove the power plug when the machine will not be in use for a long time. Pay
attention to child who should not come into contact with and use the purier.
Keep the smooth air ow in the air inlet. Do not let dust, lint, hair or other
substances block the air inlet.
