Certified Diesel Particulate Filter Vendors

Following is a list of Air District certified diesel particulate filter vendors.  Certified vendors have a contract with the Air District to inspect and install the proper device for your truck which can help get your installation done quicker.  The Air District highly recommends using, but does not require, the use of an Air District certified vendor.

Un-Certified Diesel Particulate Filter Vendors

Following is a list of diesel particulate filter vendors that do not have a contract with the Air District to inspect and install filters and are therefore refered to as un-certified.   These vendors are licensed to install diesel particulate filters but because they have not entered into a contract with the Air District the installation and inspection of devices may take longer than devices installed by a Certified Vendor..
