Quick answer: This coway ap-1512hh replacement filter guide highlights the evidence, practical fit, and buying limits that matter before you decide.
Which filter fits the Coway AP-1512HH?
| Your purifier | Correct filter | Compatibility note |
|---|---|---|
| Coway Airmega Mighty AP-1512HH, white or black | AP-1512HH-FP, SKU 3304899 | Correct genuine set |
| Coway Airmega 200M, AP-1518R | Same AP-1512HH and 200M set | Coway confirms shared compatibility |
| Coway Mighty2 AP-1512N | AP-1512N-FP Max2 | Does not fit the older AP-1512HH |
| Coway MightyS AP-1512HHS | MightyS-specific Max2 filter | Do not assume AP-1512HH compatibility |
“Mighty” has become a family name, which makes filter listings unusually confusing. The original AP-1512HH, the WiFi-enabled MightyS, and the new Mighty2 use different internal arrangements. Similar model names do not make their filters interchangeable.
If your label says AP-1512N, use our Coway Mighty2 replacement-filter guide. If you are comparing the old and new machines, see the AP-1512HH vs Mighty2 comparison. That two-minute model check prevents the most expensive ordering mistake in this category.
What is included in the genuine 3304899 set?
Coway’s genuine AP-1512HH and 200M set includes one pleated True HEPA filter and two thin deodorization filters. It does not include the washable plastic pre-filter already inside your purifier. The three physical layers work in this order from the room side toward the fan:
- Washable pre-filter: catches hair, lint, and larger dust. Clean every two to four weeks and dry fully before reinstalling.
- Deodorization filter: a thin carbon-treated sheet for limited odor and gas reduction. Coway supplies two because it recommends a six-month change interval.
- True HEPA filter: the main particle filter for airborne dust, pollen, dander, and smoke particles. Coway recommends replacing it after about one year.
The deodorization sheet should not be confused with a deep bed of carbon pellets. It can help with routine kitchen and pet odors, but it has little carbon mass compared with specialist gas filters. For persistent tobacco smoke, wildfire gases, paint fumes, or renovation VOCs, source removal and safe ventilation remain important. The HEPA layer targets particles, not carbon monoxide. Maintain working carbon-monoxide alarms separately.
Genuine filter price and yearly cost
On August 13, 2026, Coway listed the genuine set at $59.99, reduced from a $64.99 list price. Retailer prices change often, and Amazon coupons or subscription discounts can disappear without notice. Use $65 as a cautious annual filter budget and treat a lower checkout price as a saving.
| Option | Typical contents | Evidence level | Best use |
|---|---|---|---|
| Genuine Coway AP-1512HH-FP | 1 HEPA + 2 deodorization filters | Fit, schedule, and compatibility confirmed by Coway | Lowest fit and specification uncertainty |
| PUREBURG-compatible set | Listing-dependent; verify current package | HouseFresh found the same PM1-zero time with a PUREBURG set in one purifier test | Budget buyers who check dimensions, seal, odor, and return terms |
| Unbranded marketplace multipack | Often 2 HEPA + several carbon sheets | Seller claims and reviews only unless the exact set has independent testing | Only when price matters more than evidence certainty |
A cheap two-pack is not automatically cheaper per clean-air year. If the frame leaks, the media loads quickly, or the carbon smells unpleasant, you may replace it early or stop using the purifier. Compare delivered price, contents, recent reviews, seller identity, return policy, and the number of filters you can realistically use before buying a large multipack.
Do generic AP-1512HH filters work?
The strongest public evidence we found is narrower than many replacement-filter guides suggest. HouseFresh bought a PUREBURG-compatible filter and repeated its particle-removal test in the AP-1512HH. With the ionizer on, the purifier again reached PM1 zero in 26 minutes, matching the result obtained with the genuine filter.
That is useful evidence that one compatible set did not reduce room-cleaning speed in that test. It does not prove that every generic is equivalent to Coway. The test did not certify the filter’s claimed efficiency grade, compare bypass leakage over a full year, measure carbon adsorption capacity, test emissions from adhesives, or establish long-term durability. Generic brands can also change suppliers without changing the Amazon listing.
Owner reports are mixed. Some AP-1512HH owners say generic filters fit and work without obvious issues. Others report loose frames, reduced airflow, a chemical or musty odor, or slower smoke clearing. Similar odor and fit complaints also appear in reports about genuine filters, so packaging or batch quality can matter on either route. Anecdotes identify failure modes to check; they do not measure filtration.
Our decision rule
- Choose genuine when you want the least uncertainty, the price gap is modest, or returns would be difficult.
- Consider a tested-brand generic when the saving is meaningful and the listing matches 3304899 dimensions and compatibility.
- Return any new filter that arrives opened, damaged, visibly undersized, or produces a strong persistent odor after brief airing in a clean, dry place.
- Never buy a used air-purifier filter.
Inspect the filter before the return window closes
Open the shipping box soon after delivery, but keep the product packaging until the purifier has run normally. First confirm the model and part number printed on the package. Check that the HEPA media is dry, evenly pleated, and firmly attached to its frame. A few cosmetic pleat variations are different from torn media, crushed corners, detached glue lines, or a frame that has twisted in transit.
Place the new frame beside the old one without pressing their dirty surfaces together. Their outside dimensions and gasket position should align closely. Install the new filter and inspect all four edges with the front cover still off. A visible bypass gap matters because air follows the easiest path. If the frame rocks in the housing or cannot sit behind the retention points, stop and recheck the model number.
Run the purifier for several minutes on each speed in a ventilated room. Listen for rattling, rubbing, or a new whistling sound. Compare the outlet airflow with your normal experience after confirming that every shipping wrapper is removed. You do not need laboratory equipment to identify a damaged frame, wrong fit, blocked intake, or strong abnormal odor.
Do not perform a destructive “test” by cutting the frame or pulling apart the media. That ends your chance of a clean return and still does not prove filtration efficiency. Photograph the package label and any visible defect, then contact the seller while the order record and return period are current.

When should you replace each filter?
The manual’s schedule is a baseline based on eight hours of daily use at maximum fan speed. Your environment can move the date in either direction. Use the indicator, elapsed time, physical condition, and performance together.
| Layer | Coway baseline | Check sooner when |
|---|---|---|
| Washable pre-filter | Clean every 2 to 4 weeks | Pet hair, lint, or dust visibly covers the mesh |
| Deodorization filter | Replace every 6 months | Ordinary odors return quickly despite adequate airflow and source control |
| True HEPA filter | Replace every 1 year | Airflow drops after pre-filter cleaning, the filter is damaged or damp, or use has included heavy smoke or construction dust |
Do not judge a HEPA filter only by color. Fine media can hold particles that are not visible, while surface discoloration does not automatically mean airflow has collapsed. Do not rinse the HEPA or deodorization layer. Coway’s cleaning instructions apply to the reusable pre-filter; its maintenance table identifies the other two layers as replacement items.
If your home has pets, start by cleaning the pre-filter more often. A mat of hair on the washable screen can reduce airflow and make a healthy HEPA filter look spent. Our broader air-purifier filter schedule guide explains the conditions that shorten filter life.
How to replace the AP-1512HH filter
- Turn off and unplug the purifier. Move it to a clear area where dust from the old filter will be easy to collect.
- Remove the front cover. Pull the upper sides of the cover toward you. The magnetic panel releases without tools.
- Lift out the washable pre-filter. If it is dusty, clean it separately and allow it to dry completely.
- Remove the deodorization and HEPA filters. Handle the used HEPA by its frame and avoid shaking it through the room.
- Vacuum loose dust inside the empty housing. Use low suction on the plastic interior and sensor-area vents. Do not wet the motor compartment.
- Unwrap every new filter. Shipping plastic must be removed before operation. A wrapped filter blocks airflow and can overwork the fan.
- Install the HEPA in the marked direction. Follow the “front” label and make sure the frame sits flat against the housing with no obvious side gap.
- Place one deodorization sheet in front of the HEPA. Store the second sheet sealed in a clean, dry location for the six-month change.
- Reinstall the dry pre-filter and front cover. Check that each layer is seated before the magnetic panel closes.
- Plug in, turn on, and reset the correct indicator. The machine does not automatically know a new filter was installed.
How to reset the Coway AP-1512HH filter light
After replacing the filter named by the blinking indicator, press and hold the Reset button for two seconds. Coway uses separate Odor and HEPA indicator LEDs, so replace the indicated layer before clearing it.
If you changed a filter before its normal indicator activated, use Coway’s forced-reset sequence:
- With the reset function inactive, hold the Reset button for two seconds to enter forced-reset mode.
- Press once to select the Odor LED or twice to select the HEPA LED.
- After selecting the correct filter, hold Reset for two seconds again.
- If you make no selection for five seconds, the forced-reset mode cancels without erasing the counter.
The indicator is an accumulated-time counter, not a particle sensor looking through the filter. Resetting without replacing or checking the selected layer only clears the reminder. It does not restore airflow or adsorption capacity.
Replacement problems and quick fixes
The front cover will not close
Remove the layers and check their order. The HEPA belongs deepest in the housing, followed by one deodorization sheet and then the washable pre-filter. Confirm that no shipping plastic remains and that the HEPA frame is not upside down or caught on a tab.
The replacement light stays on
Turn the purifier on and hold Reset for a full two seconds. A brief tap may only select an indicator during forced-reset mode. If you changed the filter early, follow the full selection sequence above.
Airflow became weaker after replacement
Check for plastic wrapping first. Then compare the new frame with the old one, inspect the pre-filter, and confirm that the carbon sheet is flat. Some third-party filters use denser media or more carbon, which can increase resistance. Return a set that does not seat correctly or causes a large unexplained airflow change.
The new filter smells chemical or musty
Turn the unit off and inspect for dampness, damaged packaging, or visible contamination. A brief new-material odor can occur, but a strong or persistent smell should not be ignored. Contact the seller or Coway and use the return policy rather than trying to mask the odor with sprays.
coway ap-1512hh replacement filter: final decision
Use this coway ap-1512hh replacement filter guide to match the option to your room, usage, and maintenance needs.
A sound coway ap-1512hh replacement filter decision accounts for real-world fit, ongoing costs, and the limits of the product category.
When comparing choices, keep this coway ap-1512hh replacement filter goal in view rather than relying on a single headline claim.
This coway ap-1512hh replacement filter guide is designed to support a practical choice, not replace source control or the manufacturer instructions that apply to your model.
The correct Coway AP-1512HH replacement filter is the genuine Coway filter set sold under part number AP-1512HH-FP and SKU 3304899. Coway’s current product page may also show SKUs 3109905 or 3118096 for regional or package variations. The compatibility statement matters more than the color of the box: the set must explicitly name the Airmega Mighty AP-1512HH or Airmega 200M.
One genuine annual set contains one True HEPA filter and two flat deodorization filters. Coway recommends cleaning the reusable pre-filter every two to four weeks, replacing each deodorization filter after about six months, and replacing the HEPA filter after about one year. Those intervals are estimates, not expiration dates. Heavy smoke, pet hair, renovation dust, and long daily run times can shorten them.
Lowest-risk choice: buy the genuine AP-1512HH and 200M Filter Set, confirm SKU 3304899, and replace on condition plus the indicator.
Budget choice: a well-fitting generic can preserve particle-cleaning speed, but one successful test does not prove every generic brand, production batch, seal, carbon layer, or lifespan.
Do not buy: a Mighty2 AP-1512N-FP filter, a MightyS AP-1512HHS filter, an opened or used filter, or any listing that does not state AP-1512HH or 200M compatibility.

Coway AP-1512HH filter FAQ
Is 3304899 the correct Coway AP-1512HH filter?
Yes. Coway lists the genuine AP-1512HH and 200M filter set with SKU 3304899, plus some current regional or package SKUs. The set includes one HEPA and two deodorization filters.
Does the AP-1512HH filter fit the Airmega 200M?
Yes. Coway’s current filter page explicitly lists both the AP-1512HH and 200M as compatible with the same genuine set.
Does it fit the new Coway Mighty2?
No. The Mighty2 AP-1512N uses AP-1512N-FP, a combined Max2 filter with a different form factor. Use the model label, not the shared “Mighty” name.
Can I use the purifier without the deodorization filter?
The fan may operate, but you would lose the intended odor and gas stage and depart from Coway’s specified filter arrangement. Install all listed layers for normal use.
Can I wash the HEPA filter?
No. Wash only the reusable plastic pre-filter and dry it fully. The manual treats the deodorization and HEPA layers as replaceable, not washable.
Are generic filters as good as Coway filters?
Not as a universal rule. HouseFresh found no loss in PM1 cleaning time with one PUREBURG-compatible filter in one AP-1512HH test. That result does not validate every brand, batch, efficiency claim, carbon layer, seal, or service life. Genuine remains the lower-uncertainty choice.
Final choice: OEM or generic?
The genuine Coway AP-1512HH-FP is the default recommendation because Coway confirms the fit, contents, and schedule, and the current annual cost is moderate for an OEM set. The AP-1512HH remains a capable purifier, as the independent results in our Coway AP-1512HH review show. A correctly fitted fresh filter is a sensible way to keep it running.
A generic can be reasonable when it saves enough money to matter and comes from a seller with clear specifications and easy returns. HouseFresh’s result shows that a compatible set can maintain particle-cleaning speed, but it is evidence for that tested setup, not permission to trust every “fits Coway Mighty” label. Check 3304899 compatibility, frame fit, odor, airflow, and recent reviews each time you buy.
