Ok so I have a question i hope you can answer for me about the same make and model. Only difference is I have the black one. So one day I was curious about what would happen if I long pressed the power button for like 5 seconds for each side. Whence i did, I heard a beeping noise and then a little light lit up in the middle space directly under the buttons. Same goes for the heater side. Can you tell me whats happening when the light comes on? Ive done it numerous times and dont see any change in its performance. Pls help. Thank you

Great video! Does it have an air filter to clean out at the bottom?

I just pick one of these up yesterday. My only problem is the heater dosent get super hot. It kinda just feels like a warmer fan lol
