PHILTOP CF12527 HEPA Cabin Air Filter for Ram ProMaster

PHILTOP CF12527 is a dual-pack HEPA cabin air filter engineered to trap ultrafine particles and keep the interior air of Ram ProMaster 1500/2500/3500 (including EV) cleaner and fresher.

This replacement set from PHILTOP fits Ram ProMaster models from 2014 through 2026 (including the ProMaster EV) and uses a five-layer HEPA-rated design to reduce dust, pollen, soot, and other airborne contaminants that enter through the vehicle’s intake. Each box contains two non-washable, single-use filters sized to the OEM cavity under the hood, built to maintain consistent airflow while improving HVAC efficiency thanks to a long-fiber electrostatic layer that holds more debris without restricting air movement.

How does this filter improve in-cabin air quality?

The CF12527 uses true HEPA filtration combined with multiple functional layers to capture a wide range of airborne particles down to 0.1–0.3 microns. Independently tested to HEPA standards, the filter removes very small particulates that ordinary paper filters can miss, helping reduce the visible dust and microscopic matter circulating through the vents.

• Five-layer construction with HEPA-rated media for high-efficiency particle capture.
• Electrostatic long-fiber cotton increases particle retention without choking airflow.
• Designed for under-hood cabin intake on specified Ram ProMaster models.
• Pack includes two filters for staggered replacement or spares.

Will using this filter affect HVAC heating and cooling?

The PHILTOP design balances filtration and air passage: the long-fiber layer creates a larger dust-holding surface while leaving enough gaps for airflow, which helps preserve HVAC heating and cooling performance. That means cleaner air without putting excessive strain on the blower motor or reducing vent output.

• Long-fiber electrostatic cotton for higher dust-holding capacity.
• Maintains airflow pathways to support efficient temperature control.
• Non-restrictive profile matches factory filter dimensions for proper fit.

Which vehicles and years are compatible with the CF12527?

This filter is made to fit Ram ProMaster 1500, 2500, and 3500 models from 2014 through 2025 and ProMaster EVs from 2024 through 2026. Check the part location under the hood and the listed dimensions to confirm compatibility before purchase.

• Fits: ProMaster 1500 / 2500 / 3500 (2014–2025).
• Fits: ProMaster EV (2024–2026).
• Location: under-hood cabin air intake; verify OEM part number CF12527.

How often should I replace the PHILTOP CF12527 filter?

PHILTOP recommends changing the cabin filter every 12 months or every 12,000 miles under normal driving conditions. If you regularly drive in dusty, high-traffic, or construction-prone environments, replace the filter more frequently to retain optimal air quality and HVAC performance.

• Replacement interval: about 12 months or 12,000 miles.
• Increase frequency for heavy pollution, dirt roads, or allergy seasons.
• Single-use, non-washable filters—discard and replace when clogged.

Who is this for: Drivers and fleet managers who operate Ram ProMaster 1500/2500/3500 vans (including the newer ProMaster EV) and want a higher-grade cabin filter that combines HEPA-level capture with preserved HVAC airflow. This PHILTOP CF12527 two-pack suits people who need reliable, OEM-compatible replacements for regular maintenance, especially in urban or dusty driving conditions where small particles can accumulate quickly.
