A friend of mine just moved back in town from up north. He is selling his VW and has sold some of the maintenance items he's bought over the years. He has three Premium Guard PA4622 that fit my Passat. He just gave them to me. After looking these up, they have the pre-filter felt type foam material I've always seen named as a "winter or anti-condensation" filter. These ok to use in warm climate? PG website just lists it as the filter for my car without caveat.

I thought as much but didn't know if I was missing something. Thanks. I will certainly use them.

If you drove in the snow, whatever snow that makes it to the filter, will get stuck to the prefilter instead of the cellulose filter, reducing the filter's effectiveness. In non-winter conditions, it's a prefilter, so it's fine for it also.

After looking at these closer this morning, you can see the boxes were stored somewhere humid as there's faint water stains on the box and corner of filters themselves. I'll pass. He agreed, not good.

The assumption is water but could be some other chemicals from his garage. He didn't know either. But you're right, probably fine.

Yeah, if there are no visible stains on the filters (only on the box), then they are probably fine.
