“I followed the instructions for changing the air filter, however after I hold down the button for 3 seconds as directed, it still remains red. So, it looks like the filter still needs changing although I know I just changed it. Can you help with this?”

• Hi there! Thanks for reaching out and I'm sorry for the trouble. You'll want to hold the button down for a solid 15 seconds as opposed to 3.
