KARCOCA Cabin Air Filter for Silverado 1500 (2019–2024) — HEPA + Activated Carbon

The KARCOCA CF11966 is a direct-fit cabin air filter engineered for Silverado 1500 (2019–2024) and many GM models, using a three-layer HEPA and activated carbon construction to help reduce dust, pollen, and odors inside the cabin.

If you want cleaner airflow in your Silverado or another compatible GM vehicle, this replacement cabin filter combines melt-blown electrostatic media, a HEPA layer, and nutshell activated carbon to capture fine particles and mitigate common outside odors. It fits OEM-equivalent reference numbers CF11966, 13356914, 13356916, 13508023, 22743911, 23135671, and 23393247 and suits a wide range of Buick, Cadillac, Chevrolet, and GMC models.

How does this filter improve in-cabin air quality?

The CF11966 uses a layered approach: an electrostatic melt-blown layer to attract and hold small particulates, a HEPA-style layer for fine particle capture, and activated carbon to adsorb gases and odors. Together they reduce dust, pollen, and vehicle exhaust smells carried into the passenger compartment.

• Melt-blown electrostatic media traps microscopic particles.
• HEPA-like layer captures fine dust and pollen.
• Nutshell activated carbon absorbs odors, VOCs, and fumes.
• OEM-equivalent fit minimizes installation adjustments.

Will this filter fit my truck or SUV?

The KARCOCA CF11966 is designed as a direct replacement for many GM cabin filter applications. It lists compatibility for numerous models and model years, including Silverado 1500 trims from 2019 through 2024 and several other Buick, Cadillac, Chevrolet, and GMC vehicles.

• Direct fit for Silverado 1500 (2019–2024) and Silverado 1500 LTD (2022).
• Fits multiple GM SUVs and sedans: Tahoe, Suburban, Equinox, Traverse, and more.
• Matches OEM reference numbers for easy cross-checking.
• Compatible with EV models like Bolt EV/EUV and Hummer EV Pickup where listed.

How often should I replace this cabin air filter?

Replacement intervals depend on your driving environment and mileage. KARCOCA recommends swapping the filter every 12 months or roughly every 12,000 miles; if you regularly drive through dusty, urban, or high-pollen areas, check and replace it more often to maintain airflow and filtration performance.

• Standard recommendation: replace annually or every 12,000 miles.
• Inspect sooner after heavy dust exposure or seasonal pollen spikes.
• Replace immediately if you notice reduced HVAC airflow or persistent odors.
• Keep a replacement on hand for routine maintenance intervals.

Is installation difficult and what should I expect?

Installation is typically straightforward and mirrors replacing the OEM cabin filter: access the filter housing behind the glove box or under the dash depending on the vehicle, remove the old element, and insert the KARCOCA CF11966 with the airflow arrow aligned correctly. No special tools are usually required.

• Most installs require basic hand tools or no tools at all.
• Follow vehicle-specific instructions for glove box or under-dash access.
• Confirm airflow arrow orientation before final assembly.
• Check seals and housing for debris during replacement.

Who is this for: Drivers who own a compatible GM vehicle — including Silverado 1500 owners from 2019–2024 — who want a higher-filtration replacement that balances particle capture with odor reduction. It’s appropriate for commuters, families, and anyone regularly exposed to urban pollution, allergens, or highway dust who prefers an OEM-fit swap using established reference numbers.
