ITESIER Cabin Air Filter Kit for Freightliner Cascadia 2018-2025 – 1 Fresh + 2 Recirc (3pc)

Enhance your Freightliner Cascadia cabin air

Upgrade to the ITESIER Cabin Air Filter Kit and experience a refreshed interior environment on long hauls or daily drives. This complete 3-piece kit is tailored for Freightliner Cascadia models from 2018 through 2025, covering both Day Cab and Sleeper Cab configurations. The package includes one fresh air filter and two recirculation filters, all engineered for a precise OEM fit and straightforward installation.

Filtration design that works with your lifestyle

Four layers of filtration employ a deliberate sequence of gaps from large to small. This stepped structure aims to capture a wide range of particles while preserving optimal airflow, helping you maintain cabin comfort without sacrificing performance.

What’s in the kit and how it helps

• OEM-compatible parts and part numbers listed in the kit’s specs, ensuring a snug fit with your Cascadia.
• One fresh air filter located under the hood to filter intake air before it enters the cabin.
• Two washable and reusable recirculation filters designed to sit under the passenger-side dashboard (Day Cab) or inside the sleeper compartment (Sleeper Cab).
• Durable filter media that can be cleaned and reused, offering a practical reuse option between replacements.

For daily use, the configuration supports clear air distribution and easier maintenance. In sleeper setups, the second recirculation filter helps manage air quality within the sleeping area, while Day Cab owners get a focused recirculation filter under the dash to balance airflow with interior comfort.

Clear installation notes

• The fresh air filter sits under the hood, while the first recirculation filter lives under the passenger-side dashboard for Day Cab models.
• Sleeper Cab configurations require a second recirculation filter installed on the driver side inside the sleeper compartment.
• Designed for straightforward mounting, the kit aims to fit without modifications, making routine maintenance smoother.

Practical benefits you might notice

While results can vary, users often report a sense of improved interior airflow, a reduction in outside odors, and a more comfortable cabin environment during long drives or multi-day trips. The washable recirculation element adds a reusable option to help manage costs over time.
