Nissan Cabin Air Filter 27277-JA00A – Altima (2007–2016) restores crisp airflow and consistent defogging with OE-accurate dimensions, tight perimeter sealing, and low-restriction pleat geometry. High-efficiency microfibers capture pollen, soot, and fine road dust without overworking the blower, preserving HVAC quietness and durability. A humidity-resistant frame maintains shape through seasonal swings, preventing bypass leaks. Choose the carbon-media variant to reduce urban odors and ozone during city commutes. Clear orientation arrows and a true drop-in fit simplify DIY replacement in minutes. Refresh annually or every 15–20k km depending on climate and usage. Protect the evaporator, improve cabin comfort, and enjoy cleaner, calmer drives in your Altima.
