A:Answer Hi Gray, that's a great question! When it's time to replace the PECO filter, your Air Pro status will show Replace or Replace now on the display. If you're enrolled in the Filter Auto-Refill Plan, your filter will automatically be replaced every 6-months. Upon changing the filter, the device will automatically reset the filter status. If you have any additional questions or concerns, I recommend visiting our Help Center at help.molekule.com.
