Premium Guard PUREFLOW Cabin Air Filter PC99452X — Activated Carbon 4-Layer Fit for Nissan/INFINITI Models (2019–2027)

The Premium Guard PUREFLOW PC99452X is a multi-layer cabin air filter that traps dust, pollen and odors to keep your vehicle’s interior air cleaner and HVAC system working efficiently.

Replacing a worn cabin filter is one of the simplest ways to improve in-car air quality and preserve climate control performance. The PUREFLOW PC99452X combines four filtration layers with an activated carbon media to reduce airborne particles and everyday smells from traffic and exhaust. It’s designed as a direct-fit replacement for a range of Nissan, INFINITI and compatible Renault vehicles — check your owner’s manual or the vehicle filter lookup to confirm fitment for your model and year.

How does this filter improve the air inside my car?

The PC99452X uses stacked filtration layers to intercept contaminants before they reach the cabin. Larger debris like leaves and road dust is caught in the outer layer while finer particles and pollen are captured deeper in the media. An activated carbon layer helps adsorb common odors, making the cabin air smell fresher without masking scents with fragrances.

• Four-layer construction separates large particles, fine dust, and pollen for improved capture efficiency.
• Activated carbon layer reduces traffic and exhaust odors.
• Helps reduce particulate load entering the HVAC system, supporting sustained blower and heater performance.

Will this filter fit my Nissan Rogue, Altima, Sentra or INFINITI QX50?

The PUREFLOW PC99452X is manufactured to match the original equipment footprint for several Nissan and INFINITI models — including specific years and engine sizes listed by the manufacturer. It replaces common OE and aftermarket part numbers, but vehicle variations exist, so a fitment check is recommended before purchase.

• Compatible models include 2021–2026 Nissan Rogue 1.5L and select 2.5L years, 2019–2026 Altima 2.5L, 2020–2027 Sentra 2.0L, and 2019–2025 INFINITI QX50 2.0L.
• Cross-references Carquest Premium 97044/97044C and Nissan H72775NA0J.
• Use the Vehicle Filter Lookup or your owner’s manual to confirm exact fitment for your VIN.

How long will this cabin air filter last and when should I replace it?

Service intervals depend on driving conditions: dusty roads, heavy traffic, or frequent urban driving increase the particle load and can shorten filter life. As a general guideline, inspect the filter at least once a year or every 12,000–15,000 miles, and replace sooner if you notice reduced airflow or persistent odors inside the cabin.

• Inspect filter annually or with each scheduled maintenance visit.
• Replace sooner when driving in dusty, polluted, or high-traffic areas.
• Signs to replace: reduced HVAC airflow, visible dirt on the filter, or lingering outside odors.

What benefits does this filter offer beyond particle capture?

Beyond removing airborne particles, the activated carbon layer helps manage everyday smells that ride in with outside air. The multi-layer media also helps protect HVAC components by limiting debris buildup, which can extend the life and efficiency of the blower motor and evaporator housing. The filter is manufactured for easy drop-in replacement and OE-style fit and sealing.

• Odor control from integrated activated carbon media.
• Protects HVAC components by reducing debris and contamination.
• Designed for direct replacement to maintain correct airflow and sealing.

Who this is for: Drivers who want cleaner, fresher cabin air and to protect their vehicle’s heating and cooling system will benefit from the Premium Guard PUREFLOW PC99452X. It’s a practical upgrade for owners of the compatible Nissan, INFINITI, and certain Renault models who prefer a multi-layer, carbon-enhanced filter that balances particle capture with odor management. If you routinely drive in urban, polluted, or dusty environments or simply want routine maintenance peace of mind, this filter is a suitable, cost-effective choice.
