PUREFLOW PC99525X Cabin Air Filter

The Premium Guard PUREFLOW PC99525X is a four-layer cabin air filter designed to trap dust, pollen, and common outdoor odors for 2020–2025 Hyundai Palisade 3.8L models.

Installed behind the glovebox, this cabin filter replaces factory media to help reduce airborne particles and manage everyday smells entering the HVAC system. It combines mechanical filtration layers with an activated carbon core so your vehicle interior receives cleaner air circulation without changing the car’s climate control performance. This product is a direct-fit option for Palisade models listed and is compatible as a replacement for Carquest Premium Filters 97166/97166P; always verify fitment with your vehicle lookup before purchase.

How does this filter improve in-car air quality?

The PUREFLOW PC99525X uses a multi-layer media structure that captures a range of particle sizes while the activated carbon layer adsorbs common odors. It doesn't add airflow resistance beyond normal design, so your HVAC system continues to work as intended while filtering out contaminants.

• Four distinct filtration layers trap fine dust, pollen, and road debris.
• Activated carbon layer reduces traffic and exhaust smells.
• Engineered for efficient airflow to protect HVAC performance.

Will it fit my 2020–2025 Hyundai Palisade 3.8L?

Yes — the PUREFLOW PC99525X is manufactured to match the factory cabin filter dimensions and mounting points for Palisade models with the 3.8L engine from 2020 through 2025. Fitment is intended to be a direct swap, but you should confirm compatibility with your vehicle's VIN or parts lookup when ordering.

• Direct-fit design for listed Palisade model years and engine.
• Replaces Carquest 97166 and 97166P if cross-referenced.
• Simple glovebox access for fast installation.

How often should I replace this cabin filter?

Replacement intervals vary by driving conditions, but a common recommendation is every 12,000 to 15,000 miles or once a year for typical use. If you frequently drive in dusty, urban, or high-pollen areas, consider inspecting and replacing the filter more often to maintain airflow and odor control.

• Standard guideline: replace roughly every 12,000–15,000 miles.
• Swap sooner in heavy traffic, construction zones, or pollen season.
• Check visually for heavy dirt, discoloration, or reduced airflow.

What are the main benefits compared to a basic paper filter?

Compared with a single-layer paper element, the PUREFLOW multi-layer design captures finer particles and the activated carbon addresses odors that plain paper cannot. This helps keep the cabin fresher and reduces the load on the HVAC system without requiring special tools or modifications.

• Multi-layer media captures finer particles than single-layer paper filters.
• Carbon layer controls common outside odors for a fresher cabin.
• Maintains designed airflow and protects HVAC components.

Who is this for: The Premium Guard PUREFLOW PC99525X is intended for Hyundai Palisade owners (2020–2025, 3.8L) who want a straightforward, higher-performance replacement cabin filter. It's a good choice for drivers who prioritize reduced pollen and dust in the cabin, improved odor management from traffic and outdoor sources, and an easy, direct-fit upgrade without modifying factory components.
