If you’re searching for the right Coway AP-1512HH replacement filter — or your Airmega’s filter indicator just lit up — you’re in the right place. This guide covers the exact filter you need, how OEM and third-party options compare (with honest notes on quality complaints), step-by-step replacement instructions, and how to reset the filter light afterward.
The short answer: the official replacement is part number AP-1512HH-FP (catalog #3304899). It’s sold on Amazon and works with both the AP-1512HH and the Airmega 200M. Third-party alternatives cost significantly less per set and perform similarly for most households — but there’s one specific quality issue you should know before buying.

Which Filters Does the Coway AP-1512HH Use?
The Coway AP-1512HH uses a three-stage filtration system. The correct Coway AP-1512HH replacement filter set (part AP-1512HH-FP) covers the two inner replaceable stages. Listed here in physical order from outermost to innermost, as Coway’s official manual names them:
1. Pre-Filter — the washable outer mesh screen on the outside of the unit. This is Coway’s term for the reusable plastic grid that captures large particles like pet hair and dust before they reach the inner filters. It is not replaced — rinse it under cold water every 2–4 weeks and reinstall. Coway sells it separately if damaged, but it does not come in the AP-1512HH-FP replacement set.
2. Deodorization Filter — Coway’s official name for the flat activated carbon layer directly behind the Pre-Filter. It absorbs odors, VOCs, and gases. Coway recommends replacing it every 6 months. The OEM replacement set includes two Deodorization Filters because this stage needs changing twice as often as the HEPA.
3. True HEPA filter — the innermost and primary replaceable filter. Captures 99.97% of airborne particles down to 0.3 microns, including pollen, pet dander, dust mite debris, and smoke particles. Coway recommends replacing it every 12 months under normal use.
Only the outer Pre-Filter (mesh screen) is washable. The True HEPA filter and Deodorization Filter must never be washed, rinsed, or vacuumed. Water destroys the HEPA filter media permanently — a wet HEPA filter provides no filtration and can damage the motor by restricting airflow once it collapses. Vacuuming dislodges and releases captured particles back into your air. When these two filters are spent, replace them — do not attempt to clean them.
Compatible models: AP-1512HH, AP-1512HH(W), AP-1512HH(B), Airmega 200M (AP-1518R), AP-1519P. Need the official manual? Download it directly from Coway: AP-1512HH User Manual (PDF) →
The AP-1512HHS (the Wi-Fi-enabled version) uses a completely different filter — the AP-1512HHS-FP — which has a honeycomb-design Deodorization Filter instead of the flat carbon mesh used in the AP-1512HH. These are not interchangeable. Buying the wrong set is the most common and costly ordering mistake. Check the sticker on the bottom of your unit before ordering.

Subscribe & Save tip: On the Amazon listing, select “Subscribe & Save” at checkout to receive an additional 5–15% off the OEM price on a recurring delivery schedule. Set the delivery frequency to every 6 months so a new Deodorization Filter arrives automatically — and you’ll get the HEPA filter on every second delivery. This brings the OEM annual cost closer to ~$30–36, narrowing the gap with third-party options significantly.
How to Avoid Fake Coway Filters on Amazon
Counterfeit AP-1512HH filters are a documented problem on Amazon. Because Coway’s filters are among the most searched replacement parts in the air purifier category, fake listings are common — and a counterfeit HEPA filter may look identical to a genuine one while providing little to no actual filtration. Here’s how to protect yourself:
Buy from the Coway store specifically
On any Amazon listing, check the “Sold by” field under the Buy Box. It should say “Coway” — not a generic third-party seller name. Amazon’s commingled warehouse system means that even a listing displaying the Coway brand can ship inventory from a third-party seller who sent counterfeit units into the same storage bin.
Check the packaging on arrival
Genuine Coway AP-1512HH-FP packaging includes the Coway Airmega logo, the part number AP-1512HH-FP, and catalog number 3304899 printed clearly. The HEPA filter should be individually wrapped in plastic. If the packaging looks generic, flimsy, or printed in low quality, contact the seller before installing.
Verify the filter fit
A genuine OEM filter seats flush against the housing with no gaps and no looseness. If the filter wobbles, doesn’t click in, or leaves visible air gaps around the edges, it’s either counterfeit or a low-quality third-party unit — return it.
Buy direct to be certain
The safest option is ordering directly from cowaymega.com or Walmart’s first-party listing (not Walmart Marketplace). Both ship OEM product directly from Coway’s own inventory, bypassing Amazon’s warehouse entirely.
Third-Party AP-1512HH Filters: Do They Actually Work?
The AP-1512HH is one of the most popular air purifiers in North America, so the aftermarket filter market is enormous — dozens of brands, most priced 40–60% below OEM. The honest answer from verified owner reviews and independent testing: quality aftermarket filters perform comparably to OEM for most households, but you need to know what to avoid.
OEM vs. Third-Party: Quick Comparison
| OEM (AP-1512HH-FP) | Cabiclean 2-Pack | |
|---|---|---|
| HEPA Standard | True HEPA, 99.97% at 0.3µm | True HEPA, 99.97% at 0.3µm |
| Annual Cost | ~$36–57/yr | ~$13–15/yr |
| Fit | Precision-cut, guaranteed seal | Good fit; occasional loose Deodorization Filter |
| Off-Gassing Smell | Rare / none reported | Possible on first use — air out 24–48 hrs |
| Warranty Risk | None | Low (Magnuson-Moss protects buyers) |
| Best For | Medical households, chemical sensitivities | Budget-conscious households, multi-unit homes |
Best Third-Party Pick: Cabiclean 2-Pack
The Cabiclean 2-pack (ASIN B07Z67NG78) is the most rigorously validated aftermarket option for this machine. Wirecutter physically tested both the Cabiclean and Durabasics filters against a genuine Coway filter in controlled smoke particle tests, and reported that both performed almost identically to the OEM in their 0.3-micron filtration measurements. A 2-pack with 6 Deodorization Filters runs roughly $25–30, giving you two years of coverage for less than the price of one OEM set at list price.

Need to Replace Only the Deodorization Filter?
Because the Deodorization Filter needs replacing every 6 months while the HEPA lasts 12 months, you may find yourself mid-year needing only the carbon layer — not a full set. Coway sells the Deodorization Filters separately, and several third-party brands offer carbon-only packs. The Breathe Naturally carbon pre-filter pack is a well-reviewed carbon-only option that fits the AP-1512HH precisely at a lower per-unit cost than buying a full set.

The Quality Complaint You Need to Know
The most consistent complaint across multiple third-party AP-1512HH filter brands is a strong chemical smell on first use. This off-gassing comes from manufacturing residue in the activated carbon Deodorization Filter, and some owners report it persisting for the first 24–72 hours. A secondary issue on some brands: the Deodorization Filter is slightly undersized and sits loosely behind the retention tabs — it’s functional once the HEPA and Pre-Filter lock into place, but feels imprecise during install.
Remove new third-party filters from packaging and leave them in a well-ventilated space (a garage works well) for 24–48 hours before installing. This eliminates the off-gassing smell that generates most 1-star third-party reviews — and it costs nothing.
If you have severe chemical sensitivities, asthma, or are buying for a medical household, the OEM filter is the lower-risk choice. For most homes, airing out a third-party filter first resolves the only real complaint. For more context on how we evaluate all purifiers in this category, see our Best HEPA Air Purifier guide.
How to Install Your Coway AP-1512HH Replacement Filter (Step by Step)
Installing the Coway AP-1512HH replacement filter requires no tools and takes about two minutes. Watch the video below, then follow the steps:
- Power off the unit. Press the power button or unplug from the wall. Never replace the filter while the machine is running.
- Remove the Pre-Filter. The washable mesh Pre-Filter snaps off the back panel — pull straight off, no twisting. Rinse under cold water, shake off excess, and set aside to dry completely before reinstalling.
- Slide out the old filter module. Behind the Pre-Filter you’ll find the combined HEPA + Deodorization Filter unit. It slides straight out. Place it into a bag for disposal — avoid shaking, as it will release trapped particles.
- Install the new Deodorization Filter first. The flat carbon Deodorization Filter sits in the frame slot at the front of the housing (the side facing outward). Seat it flat behind the retention tabs. If using a third-party filter that feels slightly loose, it will be held in place once the HEPA filter and Pre-Filter are installed.
- Insert the True HEPA filter. Slide it in behind the Deodorization Filter. The directional arrow printed on the filter should point inward toward the machine’s intake. Press firmly until it seats flush.
- Reinstall the dry Pre-Filter. Snap the mesh screen back onto the rear panel — you’ll feel it click into place. Make sure the Pre-Filter is fully dry before reinstalling.
- Reset the filter indicator light (instructions in the next section).
How to Reset the AP-1512HH Filter Indicator Light
After installing a new filter, the indicator will not reset automatically — you must do it manually or the machine will continue showing a replace-filter alert even with fresh filters installed.
To reset: With the unit powered on, press and hold the Filter Reset button on the control panel for 3–5 seconds until the indicator light turns off. The AP-1512HH has two separate indicators — one for the HEPA filter, one for the Deodorization Filter. Reset each one individually depending on which filter you replaced.
If the reset button doesn’t work: Unplug the unit from the wall and leave it unplugged for 30 seconds, then plug back in and try the reset again. This clears the control board’s memory cache and resolves the majority of stuck-indicator issues. If the light still won’t reset after this, confirm you’re holding the correct button — the AP-1512HH has separate Filter Reset and Power buttons that are easy to confuse on first use.
When Should You Replace Your Coway AP-1512HH Filter?
Coway’s official guidance for the Coway AP-1512HH replacement filter: swap the Deodorization Filter every 6 months and the True HEPA filter every 12 months. The built-in filter indicator tracks usage hours and alerts you automatically — follow that signal rather than a fixed calendar date.
That said, the indicator only measures run time — it does not detect actual filter condition. In heavy-use households, the filter can be exhausted before the light triggers. Watch for these physical signs that your filters need changing ahead of schedule:
- Odors returning despite Auto mode running. The most reliable early sign — if cooking smells, pet odors, or mustiness linger even with the purifier running, the Deodorization Filter has likely saturated.
- Reduced airflow from the top vent. Hold your hand above the unit on a known fan speed. If the airflow feels noticeably weaker than when new, the HEPA filter is clogged enough to restrict the fan.
- Fan running louder or whining. A clogged HEPA increases airflow resistance, causing the motor to work harder. A new high-pitched whine at speeds that previously ran quietly is a reliable indicator of heavy filter loading.
- Visible grey or black discoloration on the HEPA folds. When you remove the filter module, the HEPA pleats should be white or off-white. Dark grey or black patches mean heavy particle accumulation — even if the indicator hasn’t triggered yet.
- Air quality sensor staying elevated despite no obvious source. If the pollution ring stays amber or red for extended periods in a clean environment, the HEPA may be shedding captured particles back into the airstream — a sign of filter deterioration at end of life.
Reddit owners who run multiple AP-1512HH units report that the HEPA filter often performs well beyond 12 months in low-pollution environments. For allergy and asthma households, replacing on schedule is the safer approach. See our guide How Often Should You Replace Your Air Purifier Filter? for a full breakdown by use case.
Annual Filter Cost: OEM vs. Third-Party
| Option | Cost Per Set | Sets Per Year | Est. Annual Cost |
|---|---|---|---|
| OEM (list price) | ~$57 | 1 | ~$57 |
| OEM (sale price) | ~$36–42 | 1 | ~$36–42 |
| OEM (Subscribe & Save) | ~$30–36 (5–15% off) | 1 | ~$30–36/yr |
| Cabiclean 2-Pack | ~$27 (2-year supply) | 0.5 | ~$13–15/yr |
At sale prices, the OEM is reasonable. With Subscribe & Save on top, the gap between OEM and third-party narrows considerably. At full list price without any discount, third-party options cut annual running costs by roughly 75%. For households running two or more AP-1512HH units, that saving compounds significantly.
Frequently Asked Questions
What is the Coway AP-1512HH replacement filter part number?
The official OEM replacement is AP-1512HH-FP, also listed as catalog number 3304899. Each set includes one True HEPA filter and two Deodorization Filters. Compatible with the AP-1512HH, AP-1512HH(W), AP-1512HH(B), Airmega 200M (AP-1518R), and AP-1519P.
Can I use third-party filters in my Coway AP-1512HH without voiding the warranty?
Coway’s warranty covers defects in the machine itself, not filter performance. The Magnuson-Moss Warranty Act (US) generally prevents manufacturers from voiding warranties solely due to third-party consumables. That said, if a third-party filter caused physical damage to the unit, Coway could dispute the claim. For warranty-sensitive situations, stick to OEM.
How do I reset the filter light on the Coway AP-1512HH after replacing the filter?
With the machine powered on, press and hold the Filter Reset button on the control panel for 3–5 seconds until the indicator turns off. The AP-1512HH has separate HEPA and Deodorization Filter indicators — reset each one individually depending on which filter you replaced.
Why does my new AP-1512HH replacement filter smell like chemicals?
This is the most common third-party filter complaint. The odor comes from manufacturing residue in the activated carbon Deodorization Filter and typically dissipates within 24–72 hours. Fix: remove new filters from packaging and air them out in a ventilated space for 24–48 hours before installing. OEM filters rarely produce this smell.
Is the AP-1512HH filter the same as the AP-1512HHS filter?
No — they are completely different. The AP-1512HHS uses the AP-1512HHS-FP, which contains a honeycomb-design Deodorization Filter. The AP-1512HH uses the AP-1512HH-FP with a flat carbon mesh Deodorization Filter. Check the model sticker on the bottom of your unit before ordering.
The official Coway AP-1512HH-FP is the guaranteed-fit, zero-hassle choice — buy from the Coway store on Amazon or Walmart to avoid commingled inventory issues. If you want to cut running costs dramatically, the Cabiclean 2-pack is the most validated third-party option, with Wirecutter-tested filtration performance matching OEM: just air it out for 24–48 hours before first install. Either way, replace the Deodorization Filter at 6 months, the HEPA at 12 months, and always reset the indicator light after a filter change.
