My feedback for VIVA filter (Carbon):

1. It's not from Daihatsu, but PurifyAir.
2. Size doesn't fit. I need to do some cutting and it may cause the filter to be loosen.
3. Produce some noticeable noise when the fan speed is at higher level (I believe the filter cause the motor to work harder. Did not happen if using non-carbon filter from Daihatsu.)
