The PREMIUM GUARD PUREFLOW PC99273X is a four-layer cabin air filter with activated carbon that fits specified Kia Niro, Niro EV and Hyundai Ioniq models to reduce dust, pollen and common odors entering your vehicle.

Installed behind the glovebox, this replacement cabin filter helps keep the air circulating through your car’s HVAC system cleaner and fresher. Designed to match OE fitment for selected model years, the PUREFLOW PC99273X combines multiple filtration layers with a charcoal-treated media to capture small particles and control typical outside smells, helping extend the life and efficiency of your climate control components.

How does this filter improve in-cabin air quality?

The PC99273X uses a multi-layer media layout to trap airborne particles before they reach the passenger compartment. One layer targets larger debris while finer media captures smaller dust and pollen; an activated carbon layer helps adsorb odor-causing gases.
