KAX HEPA Cabin Air Filter Kit for Ram, Jeep, Mazda — 2-Pack CF11671 with Activated Carbon

KAX CF11671 is a 2-piece HEPA-grade cabin air filter kit engineered to replace the factory filter in select Ram, Jeep Grand Wagoneer/Wagoneer L and Mazda CX-7 models, delivering up to 99.9% particle filtration and activated carbon odor control.

This KAX HEPA cabin filter set combines a five-layer non-woven media with activated carbon to trap fine dust, pollen, vehicle exhaust particles and many interior odors. Designed with a long-fiber electrostatic cotton layer and a structured pleat geometry, the filters keep airflow steady for reliable HVAC heating and cooling without sacrificing filtration. Each box contains two non-reusable, non-washable rectangular filters sized to fit behind the glove box in compatible vehicles.

How does the KAX CF11671 improve in-cabin air quality?

The CF11671 uses multilayer filtration and activated carbon to capture particulates and reduce volatile compounds that cause odors. Its HEPA-standard media and electrostatic layer increase the capture rate of airborne particles while the carbon layer adsorbs hydrocarbons and smells.

• Five-layer construction including activated carbon for odor control
• High-efficiency non-woven fabric meets HEPA-level capture rates
• Electrostatic long-fiber cotton boosts particle attraction without choking airflow

Will this filter affect my vehicle’s HVAC performance?

The KAX design preserves airflow with a pleated, gap-optimized structure that provides more dust-holding area than flat materials. That means heating and cooling systems can move air efficiently while the filter captures contaminants, reducing strain on blower motors compared with overly dense filters.

• Pleated media increases surface area for dust loading
• Structured gaps improve air passage and HVAC efficiency
• Helps maintain steady cabin airflow for climate control

Which vehicles and specs does this CF11671 kit cover?

How often should I replace these cabin air filters?

KAX recommends routine replacement to maintain clean cabin air and HVAC efficiency. Typical guidance is every 12 months or about every 12,000 miles, but you should follow your vehicle manufacturer’s maintenance intervals and replace sooner in dusty or polluted environments.

• Suggested replacement: every 12 months or 12,000 miles
• Replace sooner if you drive in heavy dust, wildfire smoke, or high-traffic urban areas
• Non-washable, single-use design — discard and install a new filter
