Green or blue? What's the difference

Hello! Glad to answer your question! Green and blue are only different in color and packaging, which one to choose depends on which color you like.

What's the diameter of the cotton pads?

Hello! Glad to answer your question! The diameter of the cotton pads is 3 cm, 1.18 inches. But you can put a square piece of cotton, cover the mouthpiece and cut off the excess of the cotton piece.

Can you get replacement filters??

Hello! Glad to answer! These cotton filters can be replaced with thin cotton pads. (Small thin cotton pads used to remove makeup.) Put a thin cotton pad into the mouthpiece, and cut off the excess around the mouthpiece with scissor.

I am unable to unscrew the front of the device, even with my jar-opener pads. Any tips?

I'm surprised by that. The cap doesn't move that far, just a quick turn to the right and it's off. When using the device, I have blown the top off at least three times. So you may have a bad one. Just get another one, or two, because it truly does work. I think the price will go super high once people find out how good they are.
