Weird, never noticed any smell coming from my AX40.
Granted it's only around 3-4 weeks old.![]()
I took a look from the side facing the blower, it's a little grey.How bout hepa turn into black color?
Should wipe on interior side facing fan blower

So sorry to ask and confirm ax40 samsung ap, the hepa filter the black portion of the side of filter should be facing outward right

Scary China natural air so dusty, after 1 day turn into dark color![]()

I couldn't take the smell so I removed the carbon filter for AX40.

The carbon filter is only taped to the Hepa filter so it is very easy to remove. Just peeled away (not tear off) the black tape.
The smell is still there but after a while, it reduces a lot.
Look like so dusty.
Try to insert customise hepa 45mm if you have it and see got different or not.
