Premium Guard HEPA Cabin Air Filter PC4479HX — Fits Dodge/Chrysler/Nissan 2011–2026, Activated Charcoal for Odour Control

The Premium Guard PUREFLOW PC4479HX is a HEPA-grade cabin air filter engineered to trap very fine particles and neutralize odours for cleaner in-cabin air in compatible vehicles.

This cabin air filter combines HEPA-grade fiber media with an activated charcoal layer to reduce particulate matter and help control common traffic and environmental smells. It’s built as a direct replacement for specified OEM and aftermarket part numbers and designed for easy installation in the listed Dodge, Chrysler, Nissan and several other vehicle makes. The filter balances filtration efficiency and airflow to preserve HVAC performance while improving cabin comfort.

How does this filter remove tiny particles from the cabin air?

PUREFLOW PC4479HX uses HEPA-grade media capable of capturing very small airborne particles down to about 0.3 microns. The dense fiber matrix traps dust, pollen and combustion soot, reducing what recirculates through the ventilation system.

• HEPA-grade media targets submicron particles for improved air cleanliness.
• Layered structure reduces particulate load before it reaches the blower and vents.
• Helps protect the HVAC system from clogging with fine debris.

Can it reduce vehicle odours and smells from traffic?

The filter’s activated charcoal layer adsorbs and helps neutralize many common odors from road and environmental sources. While charcoal reduces smell intensity, it doesn’t eliminate all odours and is not a substitute for interior cleaning.

• High-grade activated charcoal targets volatile organic compounds and traffic smells.
• Charcoal layer placed behind HEPA media for staged filtration and scent control.
• Useful for reducing persistent, everyday odors in the passenger compartment.

Is this part compatible with my vehicle and easy to install?

The PC4479HX fits a range of vehicles including 2011–2020 Dodge Grand Caravan 3.6L, 2011–2016 Chrysler Town & Country 3.6L, and 2022–2026 Nissan Frontier 3.8L, among other listed models. It’s designed as a direct-fit replacement that installs in the factory HVAC housing without modifications.

• Direct replacement for the listed Dodge, Chrysler and Nissan model years and select other makes.
• Replaces common aftermarket part numbers like Carquest 90258P and MicroGard 3696HP.
• Simple drop-in installation using the vehicle’s original filter access points.

Will the HEPA media affect my vehicle’s air conditioning performance?

High-efficiency media can create a small increase in airflow resistance compared with basic paper filters, but PUREFLOW engineers the depth and pleat design to minimize impact on HVAC function. Routine replacement keeps airflow within expected performance ranges while maintaining filtration benefits.

• Designed to balance filtration efficiency with acceptable airflow for typical HVAC systems.
• Regular replacement prevents excessive restriction from accumulated debris.
• Maintains blower performance and helps protect HVAC components over time.

Who is this for: Drivers who want a higher level of in-cabin filtration than standard paper filters provide — especially those sensitive to pollen and fine dust, regularly drive in heavy traffic, or want an affordable way to reduce common vehicle odours. Ideal for owners of the specific Dodge, Chrysler and Nissan models listed, as well as the other compatible vehicles noted in the product details, who prefer a direct-fit, HEPA-grade upgrade for their HVAC system.

Note: Always confirm fitment with your vehicle’s filter lookup before purchase. Filter life and effectiveness depend on driving conditions and maintenance schedule.
