Product Details

The Bosch C3821WS (F00E369748) is a premium carbon-activated cabin air filter designed to deliver superior air quality for your vehicle's interior. This advanced filter features a mold-resistant, multi-layer media construction that maximizes both performance and durability in demanding conditions.

Three-Layer Filtration Technology:

  • Layer 1: Non-woven pre-filter layer captures larger contaminant particles like dust, pollen, and debris
  • Layer 2: Electrostatically charged microfiber layer attracts and holds elusive smaller particles including fine dust and allergens
  • Layer 3: Activated carbon layer absorbs odors, exhaust fumes, and harmful gases for fresh, clean cabin air

Key Features:

  • Mold-resistant media prevents microbial growth and maintains filter integrity
  • Carbon activation eliminates unpleasant odors and airborne pollutants
  • Multi-layer construction provides comprehensive filtration without restricting airflow
  • Direct-fit replacement for easy installation

Bosch cabin air filters are engineered to meet or exceed OEM specifications, ensuring reliable protection for your vehicle's HVAC system while providing cleaner, healthier air for you and your passengers.

I've had great service, quick shipment and awesome prices from Autoplicity. Definitely would recommend to anyone. I've placed multiple orders with them and everything is great!

Just recieved my order and the pit jug and spout were perfect. The shipping was very fast and it was by far the best price I could get on these products. Autoplicity is great.

We ordered a Impact racing helmet for $100.00 less than what we would've paid the manufacturer. We received it sooner than expected. The helmet was excellent!! We would order for this site again in the future!!! Thank you Autoplicity!!

I purchased an Airaid throttle body spacer, they has they cheapest price on the web, no one else could even compare to the prices here at Autoplicity, I will definitely order from in the future!

The prices and selection are best. The cutomer service rep. did a good job in handling all my questions, and placed my order. I will be using Autoplicity for all my auto parts.

Awesome price on this product. First time customer with you guys, but I will definitely be coming back if you keep your prices this aggressive!

Best price I found and VERY fast shipping. Very happy.
