They confirmed both filters are still Stratapore media, the just dropped the logo from the one filter. Yes, they are visibly wire-backed media through the centre.So the 3487 isn't a stratapore anymore? Oh...wait the lf16002 has the logo, the lf3487 doesn't have the stratapore logo, but still is. Am I correct? You should be able to just see the white filter media through the louvers. This filter is $25 it better be a stratpore.
