Product review (5 stars): Seems to work fine. No mold
Original Honeywell product HC-14 Series with "Protec" anti-mold growth treatment but without the blue liner as pictured in the product photo.  Not sure if that's just an old photo.  Seems to work fine.  No mold ... just hard water buildup which I guess it's supposed to do by it's "mineral and pollutant capturing" feature to prevent white dust.
