Issue Description
After upgrade Software version from V300R006 into V600R001C00spc800 the router generate this alarm: 
<RAN-Dam:BS-NE40E-04>disp alarm all
----------------------------------------------------------------------------

Alarm Information
<RAN-Dam:BS-NE40E-04>disp alarm all

Index  Level      Date      Time                        Info
1      Critical   10-11-01  13:43:27             The air filter is failed, Maybe it is
                                                                         not cleaned as scheduled. Please clean

----------------------------------------------------------------------------
air filters are installed to the air intake frame and the panel of the power module. and To ensure good heat dissipation and ventilation for the system and to prevent the accumulation of dust on an air filter, you need to clean the air filter regularly. You are recommended to clean an air filter at least once every three months. If an air filter is placed in a dusty environment, it should be cleaned more frequently.
because of that there is a Timer on the routers count down the time that air filter should be cleared.
so if you reach the time that you should clean the air filter the router will generate alarm to inform you that you should clean air filter..
Handling Process
Using the reset dustproof run-time command, you can remonitor whether the runtime of the air filter reaches the cleaning cycle.
<RAN-Dam:BS-NE40E-04>reset dustproof run-time
Info: Reset run-time of air filter success.
Root Cause
in our case:
The old software version V300R006 have a 360 days as defualt value to generate alarm.
The new software version V600R001C00spc800 have a 90 days as defualt value to generate alarm 
- so our analysis was: 
the router is already running 90 days ago, so the dust proof counter value is : 275
and when we change software version from the old to the new the dust-proof timer didn't reset automatic, 
and because the new software version have a 90 days as defualt value to generate alarm, the router generate that alarm.
Suggestions
The system generates an alarm about cleaning the air filter. After ensuring that the air filter is cleaned or does not need to be cleaned, you can use the reset dustproof run-time command to clear the alarm and remonitor the cleaning cycle of the air filter.
