Winix C610 high pitched sound

Hi,

So I bought a winix c610 today at Costco to replace my old Honeywell purifier, and I am finding that it makes a very high pitched squealing sound (kind of like a old CRT TV) whenever it runs, especially on turbo. Has anyone else experienced this?

Do you know if the Winix c909 makes the same sound? Looking for recommendations as I am definitely returning this one!
