Car filter for people with allergies???

I've read an article about special car filters for people with allergies on WSJ. Does anyone know who make those? Lexus come with those filters installed on their LS-series cars.

 

Saab and Volvo used a incabin HEPA filter IF my mind is not gone

 

Yeah, I think they do. My Tahoe has an incabin filter as well.

I wanted to see who makes the filter for the cars that are not incabin, but between outside and the airconditioning unit... and I think they can filter pollen, odor, etc.

 

again SAAB Volvo and I think BMW do that

 

I'm asking if anyone know the name of the company that makes filters for them. I'm sure SAAB, Volvo, BMW and Lexus doesn't make their own filters.

 

Why?

 

I need that info for work. I'm doing some analysis on the industry, and wanted to see if anyone have some info.

Please don't hijack the thread.

 

The Lexus ACC cabin air filter is made by a company called ACM (I can check on the Lexus forum just be sure, but I am about 95% sure it is made by ACM).

 

Thanks! I think they are same company as Freudenberg Faservliesstoffe KG (a German company that makes "MicronAir" filters). http://www.micronair.com (I've seen some ACM listing with "MicronAir")

Thanks a bunch!
