I never got around to replacing mine on my 8, but I think they should just be paper, unless they're different from all the other Mazda vehicles'. I'd call a dealer parts department just to be sure if I were you. 
*edit to add: Trussville's website has a regular paper filter and the Aldehyde filter. Apparently the Aldehyde is "100 times more effective removing aldehydes than conventional activated charcoal".

Quite a difference in price there.
Definition per Wikipedia (http://en.wikipedia.org/wiki/Aldehyde) :
An aldehyde is an organic compound containing a terminal carbonyl group, i.e., a O=CH- group attached to hydrogen or a carbon chain. This functional group, which consists of a carbon atom which is bonded to a hydrogen atom and double-bonded to an oxygen atom (chemical formula -CHO), is called the aldehyde group. The aldehyde group is also called the formyl or methanyl group.
The word aldehyde seems to have arisen from alcohol dehydrogenated. In the past, aldehydes were sometimes named after the corresponding alcohols, for example vinous aldehyde for acetaldehyde. (Vinous is from Latin vinum = wine, the traditional source of ethanol; compare vinyl.)
The aldehyde group is polar. Oxygen, being more electronegative, pulls the electrons in the carbon-oxygen bond towards itself, thus creating an electron deficiency at the carbon atom.
Owing to resonance stabilization of the conjugate base, an α-hydrogen in an aldehyde is more acidic than a hydrogen atom in an alkane, with a typical pKa of 17.
