Premium Guard HEPA Cabin Air Filter PC4479HX — Fits Dodge Grand Caravan & Chrysler Town & Country 3.6L, HEPA + Charcoal

Premium Guard PUREFLOW PC4479HX is a HEPA-grade cabin air filter engineered to trap ultra-fine particles and reduce odors for a fresher, cleaner vehicle interior.

This replacement cabin filter combines high-efficiency HEPA media with an activated charcoal layer to block fine dust, pollen, soot and many traffic odors while fitting specific Dodge, Chrysler and Nissan models. It is sized and shaped to match factory housings for a straightforward swap, and is backward-compatible with several aftermarket part numbers. The design prioritizes particle capture and odor adsorption, which can slightly affect airflow compared with basic filters — a trade-off many drivers accept for improved cabin air quality.

How does this filter improve the air inside my vehicle?

The PUREFLOW PC4479HX uses HEPA-grade fibers to capture airborne particles down to about 0.3 microns, plus an activated charcoal layer that adsorbs volatile compounds and many common odors. Together they reduce the amount of irritants and smelly exhaust components that enter your cabin through the ventilation system.

• HEPA-grade media captures very fine particulates like pollen, dust and soot.
• Activated charcoal helps reduce traffic and environmental smells.
• Multi-layer construction balances capture efficiency and service life.

Will this filter fit my Dodge Grand Caravan or Chrysler Town & Country?

The PC4479HX is manufactured to match the cabin filter housings used in 2011–2020 Dodge Grand Caravan and 2011–2016 Chrysler Town & Country models with 3.6L engines. It’s also listed for multiple other makes and models — always verify fitment with your vehicle’s filter lookup.

• Direct fit for Dodge Grand Caravan (2011–2020) 3.6L engines.
• Direct fit for Chrysler Town & Country (2011–2016) 3.6L engines.
• Check VIN or vehicle lookup for precise compatibility before purchase.

How do I install the PUREFLOW PC4479HX and what should I expect maintenance-wise?

Installation follows the same basic steps as most cabin filters: open the glove box or access panel, remove the old filter, and insert the new one in the correct orientation. Replacement interval depends on driving conditions; inspect the filter annually or more often if you drive in dusty or high-pollen environments.

• Tool-free access on many models—glovebox removal or access door exposes the filter housing.
• Replace annually or sooner in heavy-traffic, smoky, or dusty conditions.
• Observe airflow direction arrows printed on the filter for correct installation.

What sets PUREFLOW’s HEPA cabin filter apart from economy cabin filters?

Compared with standard paper or basic synthetic cabin filters, the PUREFLOW HEPA-grade media captures finer particles and the activated charcoal layer reduces a wider range of odors. That extra performance can be especially beneficial for allergy sufferers or drivers frequently in heavy traffic, though high-efficiency media may slightly restrict airflow relative to low-resistance economy filters.

• Higher particle capture efficiency for microscopic pollutants.
• Charcoal layer improves odor control over basic filters.
• Manufactured to match OEM dimensions and many aftermarket part numbers.

Who is this for: Drivers who want a noticeable upgrade in cabin air quality — especially those with allergies, sensitivity to traffic fumes, or who spend a lot of time in urban or dusty environments. If you own a compatible Dodge Grand Caravan, Chrysler Town & Country or one of the listed Nissan/Infiniti and other compatible models and you prioritize cleaner cabin air over minimal airflow resistance, the Premium Guard PUREFLOW PC4479HX is a practical replacement option. Always confirm vehicle fitment using your VIN or the seller’s vehicle filter lookup before ordering.
