Bosch Cabin Air Filter P/N:C3870WS
Bosch P3914WS cabin air filter for the 2010-2017 Chevrolet Equinox and other vehicles traps dust from the air entering the cabin through the HVAC system.
Weaker airflow from the vents, a musty smell or extra dust inside the cabin can mean the filter is clogged. A worn blower motor or a restricted duct can weaken airflow too, so find the cause before you buy a filter.
This filter is designed and tested as a direct OE replacement, with an OE-measured fit. It is listed for a wide range of Chevrolet, GMC, Hyundai, Kia and Saturn models, including as a cabin air filter for the 2013-2018 Hyundai Santa Fe and the 2011-2015 Hyundai Sonata. If your car is not named here, look up its year and model in the "Vehicles it fits" section further down the page.

Will this Chevy Equinox cabin air filter fit a 2010-2017 Chevrolet Equinox?
Yes. Bosch P3914WS is listed for the 2010-2017 Chevrolet Equinox, which takes one filter. For other years or models, see the "Vehicles it fits" section.
Is the P3914WS a Bosch HEPA cabin air filter?
No. Bosch P3914WS is a particulate cabin air filter, not a HEPA type, and it has no activated carbon pre-filter for odor removal.
How fine a dust does the P3914WS trap?
Its multi-layer construction traps over 97.5% of dust particles 3 microns or larger. The filter media is spunbound polyester along with synthetic meltblow fibers.
How do I know when this cabin air filter is due for replacement?
Weaker airflow from the vents, a musty smell or more dust inside can be signs. Your vehicle's recommended maintenance schedule sets when to replace the filter.
What does the pleat count on this filter do?
A high pleat count gives the media more surface area, which adds filtration capacity. Together with the multi-layer media, it filters without excessive pressure drop.
