·Silver ions anti-bacterial and anti-fungus
Inhibit various types of bacteria. It is washable, and the function is lasting.
·
Gree air purifier applies HIMOP and other high-technique. Through six purifi-
cation functions of anti-bacterial and anti-fungus filter, catalytic decomposition
of the cold catalyst, HIMOP efficient wiping out formaldehyde, HEPA high
efficient filter, activated carbon adsorption technology, it can effectively
remove airborne bacteria, dust, harmful gases etc.
Catalytic decomposition of the cold catalyst
It has strong catalytic ability, can decompose eliminate odors rapidly, and will not cause secondary pollution.
HIMOP can efficiently wipe out formaldehyde
It has unique functions of adsorption and catalytic decomposition. It can
catalyse and decompose hazardous substances, especially absorb them
HEPA high efficient filter
It can 99% efficiently filtrate floating particles of 0.3 micron above (bacteria,
dead mites, dust particles, etc.), and fast refresh the indoor air.
The conductive carbon can efficiently adsorb harmful gases.
The conductive carbon filter products in new type have specific activated carbon that has high
adsorption ability, which can thoroughly remove the harmful gases like ammonia, acetic acid, etc.
Plasma
It releases ionic groups, and efficiently kill the natural bacteria in the air.
Negative ion
Forests and waterfalls surrounding the air is rich in negative ions, known as "air vitamins" refreshing
mode, the release of this product negative ions, so that room air fresh and natural.

Use a vacuum cleaner to remove the dust on the detection port surface of smell sensor and dust sensor.
In order to maintain the best state, machines should be cleaned regularly.
During the clean process, machines should be unplug, not in wet hands which may
cause electric shock and injuries.
Dirt on the main frames and desks where the main frames are placed should be
clean as often as possible.
After a long time, dirt would be difficult to remove.
• Use soft fabric
Use a dry soft fabric to remove stubborn dirt.
• No volatile substance
Petrol, thinner and abstergent would cause damage to machines.
• No detergent
Chemical composition in the detergent would cause damage to machines.
• No water spraying
Shell and other things should not be flushed or washed.
When the “cleaning” light on the screen of a machine shines, filter components
should be cleaned.
• Use a vacuum cleaner first, then use water to wash the components.
• If the components are very dirty, use neutral household detergent, or after using
the vacuum cleaner, use a cleaning rag or a soft-hair brush, then use water to wash
until no residuum is left.
• After cleaning, fix the filter components again. Press the mode button for 5
seconds in the holding state, time remark would be zero cleaning, and the
“cleaning” light would turn off.

Maintenance instructions
Attention:
·
·
·
The maintenance of cotton filter, HIMOP + HEPA
filter components and activated carbon filter
1. The replacement period of cotton filter is different from operating time and placing sites.
Depending on the environment, sometimes you can use more than 1 year, but sometimes
it may also becomes deterioration in a few months.
For example: in non-smoking cases, the life of cotton filter will increase.It is
recommended to replace every 3 months.
2. When the indicator shines, it indicates the user HIMOP + HEPA filter component should
be replaced.
3. Pay attention when you replace the cotton filter. The blue surface should be
outwards,light-colored surface should be next to HIMOP + HEPA filter component.
Then correctly glued cotton filter on HIMOP + HEPA filter components
Remove the HI MOP +
HEPA filter component
4. After HIMOP + HEPA filter component is replaced, all the indicators shines at the same
time,and the "change" light on the screen goes out after the tick sound.
5. The life of activated carbon filter is about 2 ~ 3 years. When there is odor, please remove
the activated carbon filter and place it in the sunlight for 3 ~ 5 hours and then put it back.
If the odor still exists, please replace the activated carbon filter.
6. The maintenance of cotton filter, HIMOP + HEPA filter components and activated
carbon filter, it belongs to consumables, so it is not covered in warranty. There are 5
cotton filters attached to the machine.
The activated carbon filters, filter cotton and HIMOP + HEPA filter components can not be washed with water.
Remove the cotton filter monthly, clean the surface dust, and expose in the sunlight for 3 ~ 5 hours.
Remove the activated carbon filters and HIMOP + HEPA filter components every 3 months, use the vacuum
cleaner or hair dryer to clean the dust accumulating on its surface, and expose in the sunlight for 3 ~ 5 hours.
