The Model Number LUH-A602S-WCA is not on your list of humidifiers and there is no BN on the sticker on the machine.
I just opened up my Levoir classic 160 ultrasonic cool mist humidifier. There is no batch number/sticker or red numbers on it. Please advise

Cannot find the B/N# on my LVAC 200 cordless vacuum. I looked in the suggested laces without any luck.
Mine is a Core Mini-P and I found the BN which is long but then there are 4 digits detached. Where do you enter it since the model is not listed?
