CF820 Cabin Air Filter Features

This replacement filter provides:

• Activated-carbon filtration
• Helps capture dust and pollen
• Helps capture other small airborne particles
• Helps reduce common cabin odors
• Vehicle-specific fitment
• Broad Hyundai, Kia and Genesis compatibility
• Gasoline, hybrid and EV applications
• Multiple OE and aftermarket cross-references
• Direct replacement for the compatible applications listed below

The filter is designed as a replacement component, so no HVAC modification should be necessary when installed in a compatible application.

Hyundai CF820 Fitment Guide

This range includes several of Hyundai’s newest platforms, including conventional internal-combustion vehicles and the company’s dedicated Ioniq EV lineup.

Hyundai Elantra and Elantra N

The CF820 is listed for:

2021–2026 Hyundai Elantra

2022–2026 Hyundai Elantra N

That includes the high-performance Elantra N as a specifically listed application rather than assuming compatibility based solely on the standard Elantra.

Hyundai Ioniq EV Fitment

Electric vehicles still use cabin filters.

They may not need an engine air filter, but occupants still need filtered air passing through the heating and climate-control system.

CF820 applications include:

2022–2026 Hyundai Ioniq 5

2023–2025 Hyundai Ioniq 6

2026 Hyundai Ioniq 9

That gives this filter particularly strong coverage across Hyundai’s current dedicated EV lineup.

Hyundai Tucson, Santa Fe and Santa Cruz

SUV and crossover applications include:

2022–2026 Hyundai Tucson

2021–2026 Hyundai Santa Fe

2022–2026 Hyundai Santa Cruz

For customers searching by vehicle rather than filter number, confirm the model year against the table before ordering.

Kia CF820 Fitment Guide

The same CF820 filter is listed for these Kia applications:

Kia EV6 and EV9

CF820 EV applications include:

2022–2025 Kia EV6

2024–2026 Kia EV9

These applications make the CF820 a useful replacement option for owners maintaining the cabin HVAC filtration system in Kia’s newer electric vehicles.

Kia Sportage and Sorento

The supplied fitment information covers:

2023–2026 Kia Sportage

2021–2026 Kia Sorento

These year ranges matter. An older Sportage or Sorento shouldn’t automatically be assumed to use the CF820 simply because a newer generation appears in the fitment list.

Kia Niro and Niro EV

The filter is listed for:

2022–2026 Kia Niro

2023–2026 Kia Niro EV

Again, verify the model year before ordering.

Genesis CF820 Fitment Guide

Genesis compatibility is currently much narrower than the Hyundai and Kia application lists.

The supplied fitment information therefore supports the 2023–2026 Genesis GV60.

Other Genesis models shouldn’t be assumed compatible unless separately verified.

CF820 Replacement Part Numbers

One advantage of this filter is its extensive list of OE and aftermarket cross-references.

Hyundai and Kia References

The supplied product information identifies compatibility with:

These numbers are provided for replacement and fitment cross-reference purposes. This aftermarket cabin filter isn’t being represented as a genuine Hyundai, Kia or Genesis component.

Additional CF820 Cross-Reference Numbers

The supplied application information also lists the following replacement references:

1987435160, 21HYHY41, 37123200024, ADBP250045, BE-820, CAF10079P, CF12820, CU23024, CUK23024, EFK458A, ELR7422, HC8248, J1340325, K1444, K1444A, LA441, LAK441, MS6552, QFC0584, RCA438, VF2085, WACF0314, WP10651, WP2244 and WP2245.

These cross-references make it easier to compare the CF820 with the existing filter number or replacement catalog you’re already using.

Why Replace a Dirty Cabin Air Filter?

A cabin filter quietly works every time the vehicle’s HVAC system draws outside air.

That means it can collect a surprising amount of contamination over its service life.

Dust, pollen and other airborne material can gradually accumulate between the filter pleats. The activated-carbon media also doesn’t have unlimited service life.

Replacing an old filter helps restore fresh filtration media to the HVAC system and helps keep accumulated debris out of the incoming cabin airflow.

Activated Carbon Helps Reduce Odors

The addition of activated carbon separates this filter from a basic particulate-only replacement.

Activated carbon is included to help reduce common odors and pollutants as air moves through the filter.

That can be particularly useful for vehicles regularly driven in heavy traffic or urban environments.

The filter isn’t an air purifier for the entire vehicle and shouldn’t be marketed as eliminating every contaminant or odor. Its job is simpler: filter the HVAC intake air and help reduce unwanted airborne material and odors before they enter the cabin.

An Excellent Replacement for Hyundai and Kia EVs

The CF820’s application list is unusually EV-friendly.

It covers the:

Hyundai Ioniq 5

Hyundai Ioniq 6

Hyundai Ioniq 9

Hyundai Kona EV

Kia EV6

Kia EV9

Kia Niro EV

Genesis GV60

Electric vehicles eliminate plenty of traditional engine-maintenance components, but the cabin air filter isn’t one of them.

Your EV may not need spark plugs or an engine oil filter. Dust and pollen, unfortunately, did not get that memo.

Installation and Filter Direction

Cabin air filter access varies by vehicle, so follow the procedure specified for your particular Hyundai, Kia or Genesis application.

Before removing the existing filter, note how it’s positioned inside the HVAC housing.

Install the replacement filter according to the airflow direction indicated by the vehicle and filter markings, making sure the filter sits correctly in its housing without being crushed or leaving unintended gaps.

Reinstall the filter access panel and any glovebox or trim components removed for access.

Verify Fitment Before Ordering

Because the CF820 covers multiple vehicle platforms and model generations, always verify:

Year

Make

Model

Trim or powertrain when applicable

Existing OE or aftermarket filter number when available

Don’t assume compatibility with an earlier or later model year simply because the vehicle shares the same name.
