Replace the filter when it is damaged or dirty.
The replacement filter comes with an O ring, but do not use it.
1. Carefully remove the filter from the probe. Holding the filter by its collar, rotate the filter counter-
clockwise, then pull it out.
2. Without delay, install the new filter carefully on the air temperature and humidity sensor.
Rotate the filter clockwise, making sure the filter sits straight and meets the threads properly.
