Premium Guard PUREFLOW PC99452X Cabin Air Filter — Fits Nissan/INFINITI (Activated Carbon, 4-Layer)

PUREFLOW PC99452X is a multi-layer cabin air filter from Premium Guard that traps fine dust, pollen and road particles while reducing odors with an activated carbon layer.

Designed as a direct-fit replacement for select Nissan, INFINITI and Renault models, this cabin air filter balances filtration efficiency with airflow to help keep your vehicle’s HVAC system running cleanly. The four-layer media targets a mix of airborne contaminants common in daily driving and the integrated carbon layer helps reduce common outdoor and traffic-related odors. It’s a maintenance part intended for routine replacement according to your vehicle manufacturer’s schedule or when airflow and cabin smell indicate the old filter is saturated.

How does this filter improve in-cabin air quality?

The PUREFLOW multi-layer design separates and captures different types of airborne particles across distinct media layers, reducing the amount of pollen, road dust and coarse particulates entering the passenger compartment. The activated carbon layer adsorbs many odorous compounds, limiting unpleasant smells from external sources. It’s engineered to preserve sufficient airflow so the HVAC system doesn’t have to work harder than necessary.

• Four filtration layers for staged particle capture
• Activated carbon reduces traffic and exhaust odors
• Optimized pleat profile to maintain cabin airflow

Will this part fit my vehicle and replace the original filter?

PUREFLOW PC99452X is made to match OE dimensions and fitment for a range of Nissan, INFINITI and Renault models listed by the manufacturer. It is marketed as a replacement for part numbers such as Nissan H72775NA0J and common aftermarket equivalents. Always verify fit using your vehicle’s model year and the Vehicle Filter Lookup before ordering to ensure correct installation.

• Direct-fit design for specific Nissan/INFINITI/Renault models
• Cross-references Nissan H72775NA0J and select aftermarket codes
• Check Vehicle Filter Lookup to confirm year and engine match

How often should I replace the PUREFLOW cabin air filter?

Replacement frequency depends on driving conditions and local air quality; dusty or urban environments with heavy traffic typically require more frequent changes. As a guideline, inspect the filter at regular service intervals and replace it when visible dirt, odor or reduced HVAC performance is noticeable. Following the vehicle maker’s maintenance schedule is the safest approach.

• Inspect at routine service intervals or during cabin air checks
• Replace sooner in dusty, high-traffic or polluted areas
• Signs to replace: visible soiling, lingering odors, or weaker airflow

Does installing this filter affect HVAC performance or efficiency?

PUREFLOW is engineered to balance filtration efficiency with minimal airflow restriction so the HVAC blower can function normally. Properly fitting filters help the climate control system maintain cabin temperature and reduce strain on blower motors. Incorrect or clogged filters can reduce airflow and increase system wear, so correct installation and timely replacement are important.

• Designed to preserve adequate airflow while filtering particles
• Helps protect HVAC components by limiting debris ingestion
• Correct installation prevents air leaks and maintains efficiency

Who is this for: Drivers of compatible Nissan, INFINITI or Renault models who want a cost-effective, OE-style cabin air filter focused on particle capture and odor control. It suits vehicle owners performing regular maintenance who prefer a direct-fit aftermarket option that matches original dimensions and supports healthy cabin air without significantly restricting HVAC airflow.
