Description

The Bosch P3730WS is a particulate cabin air filter designed to protect passengers from pollen, dust, and dirt particles. It features multiple layers of protection, including a melt-blown electrostatic layer, to trap microscopic pollutants and provide cleaner air inside the vehicle. This filter is engineered for professional installers and replaces original equipment (OE) part numbers such as 19257782 and 12489749.

Constructed with spunbond polyester and synthetic meltblown fibers, the P3730WS offers structural ribs for added stability and durability. It is designed to capture 80% of dirt and environmental particles, including diesel soot and bacteria. The filter is recommended for replacement every 12,000 miles.
