Where to find HEPA filters for '97 Venture?

Hi!
I'm looking for a source supplying HEPA filters for my '97 Venture van. The only place so far is at the dealer, which takes time and is fairly pricey. I've cleaned our existing filter, but after 200,000 miles there's not much left. Thanks!

I think NAPA may have a listing for cabin filters.

I found cabin filters for my 98 Venture LS at my local PEP BOYS automotive store.

Yeah, the cabin air-filters are starting to show up at most auto parts stores these days. A year or two ago, if you asked for one you'd get the 'ol blank-stare, mouth hanging open, eye's blinking kinda reaction :uhoh: . Then they were typically a dealer/order item. IIRC, the last one I bought was for a 1997 buick century, and it was like $19 at a dealer. They do last a long time, but should be changed out every 3yrs or so.
G/luck
