Related to Filter
Related to Use
Please purchase directly from the DREO oicial website at www.dreo.com
or through the DREO app.
Where can I buy a new filter?
I changed the filter,
but the Filter Change Reminder is still on.
There are several factors that can impact the filter life, including the
indoor air quality level, length of operation and particle density in the air.
If your room has a beer air quality level and/or you don't use your air
purifier often, the reminder will take longer to light up.
The Filter Change Reminder has not turned on
for a long period of time.
Check if the power is connected, the power cord is damaged, or the
electrical outlet is powered.
Why is my air purifier not working?
The Filter Change Reminder will not automatically reset. Please press
and hold to reset the reminder, the indicator will turn o after reset.

• Make sure that there is enough space around the air purifier.
• Check if the filter packaging has been removed.
• Fan speed will be low when auto mode is switched on and air quality
is good. Try to switch to higher speed.
• Replace the filter if the filter is clogged and overloaded.
The airflow from my air purifier is too weak.
• Check if the filter packaging has been removed.
• Make sure the windows are closed as polluted air may continue coming
in from outside of the windows.
• The overloaded filter will make the fan work harder to pass the air
through. Consider replacing the filter if it is clogged.
• Do not place in crowded areas and corners.
• Check if air outlet and inlet are obstructed.
My air purifier doesn't improve the air quality.
• Switch the air purifier to sleep mode or lower purifying speeds.
Why is my air purifier making a loud noise?
• It's recommended to move the appliance to a dierent location,
replug it, and check the indicator light again. If the issue persists,
please contact our Customer Support.
Why is the Air Quality indicator is always red?

• The Air Quality Sensor detects PM 2.5 particles but cannot detect
odors. If you feel that the indoor air odor is relatively strong, it is
recommended to manually open the highest purifying speed.
The odor in the room is very strong, but the Air
Quality Indicator is only green or blue.
• The Air Quality sensor reports the presence of airborne particles, but it
cannot detect gas. Please make sure there is no gas contamination
inside your room.
Why is the Air Quality indicator always blue?
• Make sure the air purifier is operating on a flat, stable surface.
• If the unusual noise still exists, there may be external objects blocking
the air openings. Please contact our customer support.
Why is my air purifier making an unusual noise?
• During the initial few days, new air purifiers produce a plastic smell
which is normal and will dissipate eventually.
• Do not add essential oils or diusers into the air purifier or use in a
excessively humid area. Humidity will cause mold to grow.
• If the filter has absorbed pollutants to its maximum capacity, then the
smell may come from the dirty filter. Please replace the filter when
necessary.
Why does my air purifier produce an unpleasant smell?
