Air purifier, MX1-C model, mounting hardware included. It was attached to the DR30 I used to own. I'm selling it because it's a hassle to install it on the DR30 I currently own. It worked back then, but its current condition is unknown. For those who understand old cars and appreciate this type of product, how about it? However, no returns accepted. Please read my self-introduction and only proceed if you agree. - Model: MX1-C - Brand: PURETRON - Manufacturer: KANTO SEIKI - Included: Mounting hardware and screws Thank you for looking.
