We have the Pega 100 - Our filter light turned on. We just replaced the filter, and the light will not turn off. I tried resetting by holding the button down until the sound came on. Light is still on.
You need to reset the machine by pressing the "On/ off" button until the buzzer beeps after changing the filter. If the problem is still not solved after such operation, please record a video of relevant details and send it to: support@okaysou.com. We will give you a perfect solution as soon as possible after we know the specific situation.
I had the same problem with my Pega100 air purifiers. The trick is to press the power/on/off button and keep pressing it as you plug the unit back in after you replace the filter. Doing this will reset the indicator light. Hope this helps.
fernhill63 You can try to press the power/on/off button and keep it pressed while you plug the unit back in after replacing the filter. This will reset the red light and then you can press the power/on/off button one more time to turn the unit back on.
