Bosch P3956WS Workshop Cabin Air Filter

The Bosch P3956WS Workshop Cabin Air Filter is specifically engineered for professional installers dedicated to helping customers breathe fresher, cleaner air. This particulate cabin air filter offers a 99% efficiency rate at 3 microns or greater in capturing dirt and other environmental particles, preventing them from entering your vehicle's heating, ventilation, and air-conditioning (HVAC) system.

Advanced Three-Layer Filtration Technology:

• 1st Layer - Non-woven pre-filter layer captures larger particles
• 2nd Layer - Electrostatically charged microfiber layer attracts and holds elusive smaller particles
• 3rd Layer - Non-woven cover layers add stability to protect the microfiber layer from damage and acts as an additional barrier to harmful elements

Key Features:

• High pleat count provides greater surface area for higher filtration capacity
• Foam perimeter gasket or rigid frame included where specified by OE
• Multi-layer media maximizes performance and durability
• Helps reduce airborne allergens, dust, and contaminants

Cabin filters should be inspected at least once a year; however, Bosch recommends following replacement at manufacturer-specified intervals. Signs that you may need a new cabin air filter include reduced air flow through your HVAC system or noise coming from the fan. This filter is compatible with select 2015-19 Hyundai Sonata and 2017-19 Kia Cadenza vehicles.
