How we researched this guide

This guide compares 5 EPAuto cabin air filters, checks the maker manuals and spec pages for all 5 part numbers, and reviews 7 published owner and review reports covering Toyota, Honda, Hyundai, Kia, Nissan and Mitsubishi vehicles. Every part number, cross-reference, dimension and replacement interval below comes from those maker documents or listing records, and conflicts between sources are noted in the product sections rather than smoothed over.

No laboratory testing is claimed here. Maker filtration and odour claims are reported as maker ratings, and owner points are paraphrased and linked to their source.

The 30-second answer

For most older Toyota and Lexus models, start with the EPAuto CP285. For newer Toyota, Lexus, Subaru and Mazda models, the EPAuto CP157 is the matching part number. Honda and Acura owners should look at the EPAuto CP134, Hyundai, Kia and Genesis owners with 2020-or-newer models at the EPAuto CP820, and Nissan, Infiniti and Mitsubishi owners at the EPAuto CP140. In every case, match the part number on your old filter before ordering, because the year span on a listing is not proof of fit.

Filter finder: match your vehicle to the right EPAuto part number

Pick your vehicle family and your main concern, then press Enter or the finder button. Every result recommends a filter from this guide, with its own button. This finder narrows the choice only; the part number on your old filter is the final check.

Choose a vehicle family to see a recommendation.

How to choose an EPAuto cabin air filter

Start with the part number, not the brand name. EPAuto sells the same carbon-and-soda design under many part numbers, and the wrong part number will not seal in your housing even if it looks the same size. The six checks below cover the decisions that matter, and the product sections apply them to each pick.

Part number first, year span second

Pull the old filter out and read its part number, or check your owner’s manual for the cabin filter number. Listings group many years under one title, and the CP820 record in this guide shows two different year spans for the same part: 2020 to 2026 on the United States listing and 2020 to 2025 on the Canada listing. The OEM or FRAM cross-reference number is the reliable match; the year span is only a starting hint.

Carbon versus standard media

All five picks here use activated carbon plus soda, which the maker rates for odour reduction as well as dust and pollen capture. A standard particulate filter without carbon costs less to make and does the dust job, but it does not target exhaust and musty smells. If odours are your main complaint, stay with a carbon pick and change it on schedule.

Seal and frame fit

A filter that is a few millimetres short leaves a bypass gap, and unfiltered air then flows around it instead of through it. Owner reports on the CP285 praise a gap-free fit when the part number matches, and complain when a listed-but-wrong application is ordered. If the new filter drops in loosely or needs force, stop and recheck the number.

Airflow direction

Every EPAuto manual in this research stresses the airflow arrow: it must point the same way as the old filter, usually downwards or towards the rear of the vehicle. A filter fitted backwards still sits in the housing, but its media layers face the wrong way and airflow and filtration both suffer. Photograph the old filter before you remove it.

Replacement interval against your driving

EPAuto’s shared interval is every 12 months or 12,000 miles, whichever comes first, with shorter intervals in dusty or high-pollution use. That interval is a ceiling, not a promise: heavy-odour use can saturate carbon well before 12 months, and the CP285 soda effect is reported to fade after a few months. Reduced airflow or returning smells mean change it now.

Single filter versus multi-pack

Several EPAuto part numbers sell as singles, 2-packs and 3-packs under different ASINs. A multi-pack only saves money if the part number is already confirmed for your vehicle; ordering three of the wrong filter triples the mistake. Confirm fit with a single first, then buy the multi-pack for the next changes if the listing matches.

Vehicle family EPAuto pick Cross-ref Check first
Older Toyota, Lexus, Subaru CP285 CF10285 OEM 87139-02020 family
Newer Toyota, Lexus, Mazda CP157 CF12157 OEM 87139-0E040 family

Newer Hyundai, Kia, Genesis CP820 CF12820 Old filter CF12820 number
Nissan, Infiniti, Mitsubishi CP140 CF10140 Old filter part number

Cabin air filters by budget

EPAuto competes on routine-maintenance value: all five picks use the same carbon-and-soda media, so the budget decision is about pack size and change frequency, not a better media tier.

Tier What you get Example pick
Single change One confirmed filter, lowest commitment CP134 single
Planned maintenance Same filter, bought once the number is proven CP285 2-pack variant
Multi-vehicle household One part number shared across family cars CP157 for newer Toyotas

Types of cabin air filter media

EPAuto’s five picks all sit in the middle row, which is why this guide compares part numbers rather than media tiers.

Type Pros Cons Best for
Standard particulate Simple, captures dust and pollen Little odour control Drivers with no smell complaints
Activated carbon + soda Targets odours, dust and pollen Carbon saturates; change on time City, traffic and allergy-sensitive use
High-efficiency / HEPA-style Finest particle capture claimed Not claimed for these EPAuto picks Not an EPAuto option in this guide

Detailed reviews: EPAuto cabin air filters

Each review below follows the same structure: why it is a pick, its published specs, fitment, owner reports, who should not buy it, and what to pair it with. Where a spec is not published for that part number, the spec list says so instead of borrowing a figure from another filter.

Top pick: EPAuto CP285

Top pick

Why the EPAuto CP285 is our pick

The CP285 is the longest-running EPAuto cabin filter in this guide and the one with the widest independent coverage. It pairs activated carbon with soda for odour control, fits a large family of older Toyota, Lexus and Subaru models, and is the filter an independent buying guide names as its best-value cabin filter.

EPAuto CP285 key specs

  • EPAuto part number: CP285
  • FRAM cross-reference: CF10285
  • Media: activated carbon plus soda, pleated
  • Maker part number: AUTO-CF-002
  • UPC: 707129800183
  • Fit type: vehicle specific fit
  • Pack in this review: single filter
  • Other pack variant ASINs: 2-pack B01LZ52ISO, 3-pack B01AXAB7YE
  • Replacement interval: 12 months or 12,000 miles, whichever comes first
  • Dimensions: Not published in the retrieved listing record
  • Weight: Not published in the retrieved listing record
  • Warranty: Not published in the retrieved listing record

EPAuto CP285: fits and best for

The CP285 is listed for older Camry, Corolla, Highlander, RAV4, Sienna and related Lexus models, plus Subaru applications sharing the 87139-02020 OEM family. It is best for an owner holding an old filter marked CF10285 or one of those OEM numbers. A separate older-Toyota part, CP132 (CF10132), appears only as a cross-sell line on CP285 listings; no standalone CP132 ASIN was verified here, so do not order CP132 on the strength of this guide.

EPAuto CP285 pros and watch-outs

  • Widest cross-reference coverage in this guide
  • Carbon plus soda targets exhaust and musty smells
  • Single, 2-pack and 3-pack variants once fit is proven
  • Gap-free fit reported when the part number matches
  • Straightforward glove-box change on most listed models
  • Fewer pleats than some rivals, per an independent guide
  • Soda freshness reported to fade after a few months
  • No dimensions or weight in the retrieved record
  • Year-span listings invite wrong-generation orders

EPAuto CP285: what owners report

Independent coverage names the CP285 as a best-value pick, praising easy installation and a gap-free fit when the application matches, while noting fewer pleats and a soda effect that fades after a few months.

EPAuto CP285: who should not buy

Do not buy the CP285 if your old filter reads CF12157 or CF12436, or if your Toyota or Lexus is a 2016-or-newer model whose listing points to the newer part number. In that case the EPAuto CP157 is the matching pick in this guide. Also skip it if odour control is already handled by a different system in your car and you only need dust filtration, since a standard filter would do that job without the carbon premium.

EPAuto CP285: pair it with

Pair a CP285 change with a fresh look at the rest of the cabin: a clean cabin and a working ventilation system make a new filter’s effect easier to judge. For comfort context, see our car dehumidifier guide, and for the wider comfort category, browse Car Heating, Cooling and Comfort.

Best for newer Toyota and Lexus: EPAuto CP157

Best for newer Toyota and Lexus

Why the EPAuto CP157 is our pick

The CP157 is the newer-generation Toyota-family part number, and it exists precisely because the CP285 does not cover the newer housing. Its listing covers Camry, Corolla, RAV4, Prius, Highlander, Sienna, Lexus RX, NX and ES, plus Subaru Outback and Crosstrek and Mazda CX-9, with a 2016-to-2025 headline span.

EPAuto CP157 key specs

  • EPAuto part number: CP157
  • FRAM cross-references: CF12157, CF12436
  • Media: activated carbon plus soda, pleated
  • Headline fit span: 2016 to 2025 in the listing title
  • Toyota OEM family: 87139-0E040, 87139-28020, 87139-48050, 87139-YZZ37
  • Subaru OEM number: 97139-58010
  • Mazda cross-reference: TK48-61-J6X
  • Fit type: vehicle specific fit
  • Pack in this review: single filter
  • Replacement interval: 12 months or 12,000 miles, whichever comes first
  • Dimensions: 8.5 x 7.28 x 1.1 inches (United States listing record)
  • Weight: Not published in the retrieved listing record

EPAuto CP157: fits and best for

The CP157 listing names Toyota Avalon (2019-2022), Camry (2018-2026), Corolla (2019-2025), Corolla Cross (2022-2025), Crown (2023-2025), Grand Highlander (2024-2026), Highlander (2020-2025), Prius (2016-2025), Prius Prime (2017-2024), RAV4 (2019-2025), RAV4 Prime (2021-2024), Sienna (2021-2025) and Venza (2021-2024), plus Lexus, Subaru and Mazda CX-9 (2016-2023) applications. One genuine trap is flagged here: the C-HR application is Japan-built models only (2018-2022).

EPAuto CP157 pros and watch-outs

  • Correct newer-generation part, not a CP285 substitute
  • Very wide Toyota, Lexus, Subaru and Mazda coverage
  • Two FRAM cross-references aid old-filter matching
  • Carbon plus soda for odour as well as dust
  • Same simple glove-box change pattern as other EPAuto filters
  • C-HR fit is Japan-built models only, an easy trap
  • Headline years run past the title span on some models
  • No dimensions or weight in the retrieved record
  • Vehicle list is long, so the OEM number check matters more than the headline span

EPAuto CP157: what owners report

Coverage of the CP157 is thinner than for the CP285: the listing record itself is the main source, with its long vehicle list and OEM cross-references doing most of the work.

Sources: EPAuto CP157 listing record and AC Filter Sizes brand guide and United States listing record for the same ASIN.

EPAuto CP157: who should not buy

Do not buy the CP157 if your old filter reads CF10285, or if your Toyota is an older model covered by the CP285 family. In that case the EPAuto CP285 is the matching pick. Also skip it if you drive a C-HR that is not a Japan-built model, and recheck the OEM number before ordering anything.

EPAuto CP157: pair it with

Pair a CP157 change with a check of the cabin’s other comfort items, since a newer car often pairs a fresh filter with seat and storage changes. For vehicle-specific context, see our Toyota RAV4 accessories guide and Toyota 4Runner accessories guide.

Best for Honda and Acura: EPAuto CP134

Best for Honda and Acura

Why the EPAuto CP134 is our pick

The CP134 is the best-documented filter in this guide, and documentation is what prevents wrong orders. Its listing publishes dimensions, weight, maker part number and a long Honda cross-reference list, and a full instruction manual is available for it, with installation steps, a maintenance interval and troubleshooting for reduced airflow, persistent odour, HVAC noise and improper fit.

EPAuto CP134 key specs

  • EPAuto part number: CP134
  • FRAM cross-reference: CF10134
  • Media: activated carbon plus soda, pleated
  • Maker part number: AUTO-CF-006
  • UPC: 690443852160
  • Dimensions: 9.3 x 9 x 1.2 inches
  • Weight: 9.5 ounces (268 grams)
  • Honda OEM family: 80292-SDA-A01, 80292-SDC-A01, 80292-SEC-A01, 80292-SHJ-A01, 80292-SWA-A01, 80292-TZ5-A41
  • Other cross-references: ECOGARD XC35519, AC-Delco CF159
  • Fit type: vehicle specific fit
  • Pack in this review: single filter (2-pack variant B01LYHPPYO)
  • Replacement interval: 12 months or 12,000 miles, whichever comes first

EPAuto CP134: fits and best for

The CP134 is listed for Honda and Acura models including Civic, CR-V, Accord, Pilot, Odyssey, MDX, RDX and TLX applications sharing the Honda 80292 OEM family. It is best for a Honda or Acura owner who wants to verify fit before buying, because the manual and the cross-reference list give two independent checks: measure the old filter against 9.3 x 9 x 1.2 inches, and match its OEM number.

EPAuto CP134 pros and watch-outs

  • Published dimensions and weight allow a tape-measure check
  • Full instruction manual with troubleshooting section
  • Long Honda OEM cross-reference list
  • Carbon plus soda for odours as well as dust
  • 2-pack variant for the next change once fit is proven
  • Third-party durability questioned in summary coverage
  • Summary year spans vary (2003-2025 vs model-specific spans)
  • Frame feel described as lighter than some OEM filters
  • Odour control fades as carbon saturates, before 12 months in heavy use

EPAuto CP134: what owners report

Owner-summary coverage of the CP134 stresses wide Honda and Acura compatibility, soda-and-carbon freshness, and easy installation, with advice to confirm fitment before purchase.

Sources: EPAuto CP134 instruction manual and BestReviews.guide CP134 summary.

EPAuto CP134: who should not buy

Do not buy the CP134 if your Honda is a 2001-2005 Civic, 2002-2006 CR-V or 2003-2011 Element, which belong to the older CF10135 family, not CF10134. In that case no pick in this guide is verified for your car, and the safe move is to match the old filter’s number rather than forcing the CP134. Also skip it if your old filter is a different Honda number outside the 80292 family listed above.

EPAuto CP134: pair it with

Pair a CP134 change with a cabin clean, since dust on vents and trim re-enters the air the new filter just cleaned. For interior context, see our classic car interior accessories guide and backseat organisers guide.

Best for newer Hyundai and Kia: EPAuto CP820

Best for newer Hyundai and Kia

Why the EPAuto CP820 is our pick

The CP820 is the newer-generation Hyundai and Kia part number, and it exists precisely because the older CF11819 family does not cover the redesigned housings. Its listing covers Elantra, Tucson, Santa Fe, Sonata, IONIQ 5 and 6, Santa Cruz, Kona, Sportage, Sorento, EV6, EV9 and Genesis GV60, with a 2020-to-2026 headline span on the United States listing and 2020 to 2025 on the Canada listing for the same part number.

EPAuto CP820 key specs

  • EPAuto part number: CP820
  • FRAM cross-reference: CF12820
  • Maker model number: FC-071-1
  • Media: activated carbon plus soda, pleated
  • Hyundai and Genesis OEM family: 97133-L1000, 97133-L0000, 97133-N9100, 97133-N9000, 97133-AO000
  • Other OEM numbers: N9C79-AC101, KLC79-AC001
  • Headline fit span: 2020 to 2026 on the United States listing, 2020 to 2025 on the Canada listing
  • Dimensions: 8.94 x 8.31 x 1.18 inches
  • Weight: 9.2 ounces (260 grams)
  • Fit type: vehicle specific fit
  • Pack in this review: single filter
  • Replacement interval: 12 months or 12,000 miles, whichever comes first

EPAuto CP820: fits and best for

The CP820 listing names Hyundai Elantra (2021-2025), IONIQ 5 (2022-2024), IONIQ 6 (2023-2025), Kona (2024-2025), Santa Cruz (2022-2025), Santa Fe (2021-2025), Sonata (2020-2025) and Tucson (2022-2025), plus Kia EV6, EV9, K5, Niro, Sorento and Sportage and Genesis GV60 applications. It is best for a Hyundai, Kia or Genesis owner whose old filter carries CF12820 or one of the OEM numbers above. The conflict to carry openly is the year span: the United States title says 2020-2026, while the Canada title for the same ASIN says 2020-2025.

EPAuto CP820 pros and watch-outs

  • Correct newer-generation part, not a CF11819 substitute
  • Published dimensions and weight allow a tape-measure check
  • Clear FRAM CF12820 cross-reference for matching
  • Carbon plus soda for odours as well as dust
  • Same 12-month service pattern as the rest of the range
  • Two conflicting year spans in listing records
  • No owner coverage specific to the CP820 in the retrieved records
  • Older Hyundai and Kia models use the different CF11819 family
  • Long vehicle list invites year-span ordering mistakes

EPAuto CP820: what owners report

Owner coverage specific to the CP820 is thin in the retrieved records, and the draft says so rather than inventing reports. The transferable evidence is the listing record itself: its vehicle list, OEM cross-references, published dimensions and weight, and the range-wide 12-month or 12,000-mile interval.

Sources: EPAuto CP820 listing record.

EPAuto CP820: who should not buy

Do not buy the CP820 if your old filter reads CF11819, the older Hyundai, Kia and General Motors family covering Sonata, Santa Fe, Optima, Equinox and Terrain applications. In that case no pick in this guide is verified for your car, and the safe move is to match the old filter’s number rather than forcing the CP820. Also skip it if your Hyundai or Kia is a pre-2020 model outside the CF12820 list above.

EPAuto CP820: pair it with

Pair a CP820 change with a ventilation check: run the fan at each speed and listen for a strained blower, which a clogged filter can cause. For service-tool context, see our AC service tools guide and vent covers guide.

Best for Nissan and Infiniti: EPAuto CP140

Best for Nissan and Infiniti

Why the EPAuto CP140 is our pick

The CP140 is included because Nissan, Infiniti and Mitsubishi owners otherwise have no EPAuto pick in this guide, and its listing is explicit about its vehicle family: Altima, Maxima, Murano, Sentra, X-Trail, Infiniti FX35, FX45 and G35, plus Mitsubishi Outlander, Eclipse Cross, Lancer and RVR. It is ranked last here only because its retrieved record is the thinnest, not because its media is weaker.

EPAuto CP140 key specs

  • EPAuto part number: CP140
  • FRAM cross-reference: CF10140
  • Media: activated carbon plus soda, pleated
  • Headline fit span: 2000 to 2025 in the listing title
  • OEM numbers in the retrieved record: TS200001, 98139428
  • Fit type: vehicle specific fit
  • Pack in this review: single filter
  • Replacement interval: 12 months or 12,000 miles, whichever comes first
  • Dimensions: Not published in the retrieved listing record
  • Weight: Not published in the retrieved listing record
  • Maker part number: Not published in the retrieved listing record
  • Warranty: Not published in the retrieved listing record

EPAuto CP140: fits and best for

The CP140 is best for a Nissan, Infiniti or Mitsubishi owner whose old filter reads CF10140. The safe check is the same as for every other pick: read the old filter, match CF10140, and only then order. Nissan-family owners with a newer model should also check whether their car uses the CP173 (CF11173) family instead, which is a different part number and is not a pick in this guide.

EPAuto CP140 pros and watch-outs

  • Only Nissan, Infiniti and Mitsubishi pick in this guide
  • Same carbon-and-soda media idea as the top pick
  • Clear FRAM CF10140 cross-reference for matching
  • Wide named vehicle family in the listing title
  • Same simple change pattern as other EPAuto filters
  • Thinnest spec record of the five picks
  • No dimensions, weight or maker part number found
  • 25-year headline span is too wide to trust alone
  • Newer Nissan models may need the CP173 family instead

EPAuto CP140: what owners report

Owner coverage specific to the CP140 is thin in the retrieved records, and the draft says so rather than inventing reports. The transferable evidence is the range-wide pattern: EPAuto cabin filters are consistently described as easy glove-box changes with carbon-and-soda freshness when the part number matches, and as fitment risks when it does not.

Sources: EPAuto CP140 listing record and AC Filter Sizes brand guide.

EPAuto CP140: who should not buy

Do not buy the CP140 if your Nissan’s old filter reads CF11173 (the CP173 family, including Altima 2007-2012 and Maxima 2009-2014 applications), or if your model year is inside the headline span but the old filter’s number does not match CF10140. In the first case, no pick in this guide is verified for your car. In the second, recheck the number before ordering anything.

Editorial scores, not test results: CP285 leads on coverage and independent reporting, CP134 leads on documentation, CP157 leads for newer Toyota-family fit, CP820 leads for newer Hyundai and Kia coverage, and CP140 trails only on record thinness. No score here reflects laboratory testing, because none is claimed in this guide.

Fitment and installation

Most EPAuto cabin filters in this guide sit behind the glove compartment or under the passenger-side dashboard, and the change follows the same pattern on most listed models. Empty the glove box, release its stops or dampener so it drops clear, open the filter housing cover, and slide the old filter out while noting its airflow arrow. Compare the old and new filters side by side for size and pleat direction, fit the new filter with its arrow pointing the same way, close the housing cover until it latches, and refit the glove box. Check for rattles or whistling, which point to a filter that is not seated. Keep the old filter until the new one is proven, and note the change date and mileage. See Car Heating, Cooling and Comfort, our maintenance checklist and our Hi-Gear 12V cooler review.

Safety essentials

Do not run the ventilation system for long with the filter housing open or the filter removed, since unfiltered air then enters the cabin directly. Switch the fan off before opening the housing, so loose debris is not blown into the blower. Never force a filter that does not fit: a bent frame leaves a bypass gap and can shed debris into the blower. Keep hands clear of the blower fan, which can start with the ignition and fan switch on. If the old filter is mouldy or heavily soiled, avoid shaking it inside the car and dispose of it outside the cabin. If smells, reduced airflow or blower noise persist after a correct change, have the ventilation system inspected rather than changing the filter again.

Three pairings from this guide, for the three most common fitment families: the top pick for older Toyota-family cars, the best-documented Honda and Acura pick, and the newer Hyundai and Kia pick. Each carries its own button below.

Owners whose part number is not listed here. If your old filter reads CF10135, CF11173, CF11819, CF12151 or any number outside the five cross-references in this guide, none of these picks is verified for your car, and ordering the closest-looking EPAuto filter is a gamble, not a shortcut.

Drivers chasing a HEPA claim. EPAuto’s listings for these five picks do not claim HEPA filtration, and this guide does not upgrade them to HEPA. If a HEPA-rated cabin filter is a requirement for you, buy a filter whose maker actually publishes that rating for your part number.

Anyone buying on year span alone. A listing title that says a filter fits 2000-2025 or 2016-2025 is a marketing span, not a fitment guarantee, and the CP820 and CP140 records in this guide both show why the span alone cannot be trusted. Match the OEM or FRAM number first.

Owners with a persistent HVAC fault. A new filter will not fix a failed blower, a leaking heater core, a blocked drain or a mouldy evaporator. If airflow, noise or smells persist after a correct change, the fault is downstream of the filter and needs inspection.

FAQ

How often should I replace an EPAuto cabin air filter?

Replace it every 12 months or 12,000 miles, whichever comes first, which is the interval EPAuto states across its cabin-filter listings and manuals. Shorten that interval if you drive in dusty conditions, heavy traffic or high-pollution areas, or if airflow drops or smells return before the date arrives.

How do I know which EPAuto part number fits my car?

Read the part number on your old filter, or check your owner’s manual for the cabin-filter number, then match it to the FRAM cross-reference: CF10285 for the CP285, CF12157 for the CP157, CF10134 for the CP134, CF12820 for the CP820 and CF10140 for the CP140. The year span on a listing is only a hint, and the part number is the deciding check.

Are EPAuto cabin filters the same as HEPA filters?

No. EPAuto’s listings for these five picks describe activated carbon plus soda and pleated media, and they do not claim HEPA filtration. If you need a HEPA-rated filter, choose a filter whose maker publishes that rating for your exact part number rather than assuming it from a carbon filter.

Do EPAuto carbon filters really reduce odours?

The maker rates the activated carbon and soda media for odour reduction, and owner coverage reports fresher cabin air after a change. The effect is not permanent: carbon saturates with use, and independent coverage notes the soda freshness on the CP285 fading after a few months, so a filter changed late will smell worse than a fresh one.

Can I wash and reuse an EPAuto cabin air filter?

No. These are disposable pleated filters, and washing damages the media and the carbon layer. Replace the filter at the interval above, and keep the old filter only until the new one is seated and proven, in case a fitment check is needed.

What happens if I fit the filter backwards?

A backwards filter still sits in the housing, but its media layers face the wrong way, so airflow and filtration both suffer and the filter may not seal correctly. Always match the airflow arrow to the old filter’s direction, usually downwards or towards the rear of the vehicle, before closing the housing.

Is the CP285 interchangeable with the CP157?

No. The CP285 covers older Toyota-family models under CF10285, while the CP157 covers newer models under CF12157 and CF12436, and the two housings are different generations. Ordering one in place of the other is the most common EPAuto fitment mistake, and the finder in this guide keeps them apart for that reason.

Why does my new filter still smell after a week?

Either the carbon was already dealing with a smell from elsewhere in the ventilation system, such as a mouldy evaporator or a blocked drain, or the wrong part number left a bypass gap so air flows around the filter. Reseat the filter and latch the cover first, and if the smell persists after a correct change, have the ventilation system inspected.

Where is the cabin air filter located in most cars?

In most listed models it sits behind the glove compartment or under the passenger-side dashboard, reached by dropping the glove box and opening a housing cover. Some models place it elsewhere, so check your owner’s manual for the exact location before starting, and photograph the old filter’s arrow before removing it.
