Premium Guard HEPA Cabin Air Filter PC99264HX – Fits Volvo XC60/XC90, Activated Charcoal & Baking-Soda

Premium Guard PureFlow HEPA PC99264HX is a multi-layer cabin air filter that traps 99.97% of microscopic particles and reduces odors for a cleaner in-car environment.

If you drive a compatible Volvo or Polestar from recent model years, this drop-in Premium Guard replacement filter upgrades your vehicle’s cabin air filtration with HEPA-level particle capture, an activated charcoal odor layer, and baking-soda odor neutralization. It’s engineered to match the original equipment footprint, replacing Volvo part 31407748, and is designed to help preserve your climate system’s airflow while filtering fine dust, pollen, soot, and many common airborne contaminants.

How does this filter improve the air I breathe while driving?

The PureFlow HEPA uses four filtering layers to catch large debris and submicron particles alike, delivering high-efficiency particle removal without altering your cabin layout. The HEPA-grade media is rated to capture particles down to 0.3 microns with very high effectiveness, helping reduce particulate load inside the car.

• HEPA layer captures ~99.97% of 0.3µm particles (typical HEPA performance)
• Pre-filter traps leaves, dust and larger debris
• Activated charcoal adsorbs many gases and VOCs
• Baking-soda-infused layer helps neutralize unpleasant odors

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

PureFlow PC99264HX is manufactured to the same dimensions as the referenced OE filter and is listed as a compatible replacement for Volvo part 31407748. It fits a broad range of Volvo and Polestar models across model years noted below, but it’s always good to confirm fit using your VIN or a vehicle filter lookup tool before purchase.

• Fits 2016–2025 Volvo XC90 and 2018–2025 XC60
• Fits 2019–2025 S60 and 2017–2025 S90
• Fits V60, V60 Cross Country (2020–2025), V90, V90 Cross Country (2017–2025)
• Also compatible with Polestar 1

How easy is installation and maintenance?

Installation follows the same basic steps as swapping an original cabin filter: access the filter housing (typically behind the glove box or under the cowl), remove the old element, and drop the new PureFlow unit into place. The design aligns with factory mounting points so no modification is required.

• Direct replacement—no trimming or adapters needed
• Recommended inspection or replacement interval varies by driving conditions
• May slightly affect airflow due to dense HEPA media—expect normal HVAC operation

What performance should I expect and what does it block?

Expect significant reduction of common airborne irritants like pollen, road dust, soot, and many fine particulates. The activated charcoal layer reduces many odors and certain gaseous contaminants; however, it does not eliminate all gases or guarantee protection against chemical exposure. This filter helps create a cleaner-feeling cabin, particularly for allergy-prone passengers.

• High-efficiency capture of fine particles and allergens
• Charcoal layer reduces odors and some gaseous pollutants
• Helps reduce dust buildup on HVAC components

Who this is for: drivers who own compatible Volvo or Polestar models and want an upgraded cabin air environment—especially those sensitive to pollen, fine dust, or persistent vehicle odors. It’s a practical choice for people who spend a lot of time commuting, ride-share drivers, and anyone seeking a straightforward, OEM-compatible replacement that boosts filtration performance without complex installation. Always verify fitment for your exact model and year before ordering.
