KAX Premium HEPA Cabin Air Filter for Nissan Altima — CF11776, Dual-Layer Carbon & Low-Resistance Fit

The KAX CF11776 is a premium HEPA cabin air filter designed to fit select Nissan and Infiniti models, improving in-cabin air cleanliness and odor control without altering airflow comfort.

Swap in the KAX CF11776 when your vehicle needs a performance-grade cabin filter. Built to the original equipment dimensions, this replacement uses a dual-layer carbon and HEPA-compliant media to trap fine particulates and reduce common odors while keeping HVAC airflow efficient. It's intended for easy, tool-free installation behind the glove box and is sold as a single boxed unit.

How does this filter improve the air inside my car?

The CF11776 combines a dense HEPA-grade layer with an activated carbon stage to capture both tiny particles and odor-causing gases. The HEPA-compliant layer targets very small particulates, while the carbon layer adsorbs smells from traffic and interior sources. Together they deliver cleaner-smelling air and fewer airborne irritants during daily drives.

• HEPA-compliant media captures particles down to 0.1–0.3 μm
• Dual-layer carbon matrix reduces odors and VOCs
• Independent testing indicates improved capture compared with basic OEM filters

Will installing this filter affect my car’s heating or cooling performance?

Engineered to balance filtration and flow, the KAX CF11776 reduces airflow resistance versus many aftermarket HEPA options. That means your HVAC system can maintain cooling and heating efficiency while using higher-grade filtration. The design aims to limit extra blower strain so performance remains consistent.

• Optimized pleat structure for reduced resistance
• Approximately 15% lower airflow impedance versus heavier aftermarket designs
• Maintains factory-like delivery of conditioned air to the cabin

Is this filter simple to install and will it fit my vehicle?

The filter is manufactured to match OEM cabin filter dimensions exactly, and the CF11776 is intended for a drop-in replacement behind the glove box. KAX validated fit and installation through repeated tests so most owners can change the filter without tools in under five minutes. Confirm fit using the listed vehicle application years before purchase.

• Exact OEM-matched dimensions: 11" x 9.6" x 0.7" rectangular form
• Tool-free, under-5-minute installation procedure
• Packaged as one boxed unit for simple service swaps

Which cars is the CF11776 compatible with and where is it located?

This KAX cabin filter fits a number of Nissan and Infiniti sedans and SUVs from recent model years. The intended location is behind the glove compartment, the common service position for cabin air filters. Check your owner's manual or the vehicle fit list to ensure compatibility before ordering.
