Bosch Cabin Air Filter Set P/N:P3821WS
Bosch P3933WS cabin air filter for the 2008-2012 Jeep Liberty and other vehicles traps dust particles from the air entering the cabin. This Bosch cabin filter is a particulate type, and changing it on your vehicle's recommended maintenance schedule helps the HVAC system work efficiently.
A clogged cabin air filter can show up as weaker airflow from the vents, a dusty or musty smell, or more dust on the dash. Weak airflow alone doesn't prove the filter is at fault, since a worn blower motor can cause it too.
This filter is designed and tested as a direct OE replacement for the 2008-2012 Jeep Liberty and the 2008-2009 Dodge Nitro.
Two cabin air filters.

Is Bosch P3933WS the cabin air filter for the 2008-2012 Jeep Liberty?
Yes. Bosch P3933WS fits the 2008-2012 Jeep Liberty and the 2008-2009 Dodge Nitro.
Are these Bosch car filters sold as a set?
Yes. Bosch P3933WS comes as a set with two cabin air filters.
Is this Bosch HEPA cabin air filter a true HEPA filter?
No. This is a particulate cabin air filter, not a HEPA filter, and it has no activated carbon pre-filter for odor removal. It traps over 97.5% of dust particles 3 microns or larger.
Can a clogged particulate cabin filter reduce airflow from the vents?
Yes, it can. A clogged filter restricts the air moving through the HVAC system. A high pleat count gives this filter more surface area for filtration capacity.
Can I wash and reuse the Bosch P3933WS filter?
No. This cabin air filter is not reusable. Replace it with a new one when it is clogged or when your vehicle's maintenance schedule calls for it.
