Quick replacement answer
OEM part: Coway Airmega AP-1512HH & 200M Filter Replacement Set (commonly referenced as part number 3304899). The set contains a True HEPA filter and a deodorization/carbon pre‑filter. Suggested intervals: True HEPA ≈ 12 months; carbon/deodorization pre‑filter ≈ 6 months under typical home use (replace more often in smoky, dusty, or pet‑heavy environments). Always confirm the model sticker on your unit (AP‑1512HH / Airmega 150) before buying.
What the Airmega 150 actually uses
The Coway Airmega 150 (sold in some markets as AP‑1512HH) uses a two‑part replaceable filter system: a washable or disposable carbon/deodorization pre‑filter that traps larger particles and odors, and a True HEPA main filter for fine particles. Coway’s official replacement pack for the AP‑1512HH / Airmega 150 is listed as a True HEPA + pre‑filter set (part referenced in listings as 3304899). Coway’s product description notes the True HEPA lifetime at roughly 12 months and the carbon pre‑filter at roughly 6 months.
Confirming model: if the sticker on the back of your unit shows AP‑1512HH, AP‑1512HHS, or Airmega 150 (some sellers group the 200M as compatible), the filters in the Coway AP‑1512HH replacement family match. If your label shows a different model, check that model’s guide at AirPurifierFAQ’s filter index or the model’s specific replacement page (see /filters/coway-ap-1512hh-replacement-filter/).

How to decide: OEM or generic
- Choose OEM when you want Coway‑branded packaging and the manufacturer’s stated specifications and support. OEM is straightforward if warranty, original part labeling, or verified performance matters.
- Consider vetted generics to reduce cost per filter. Compare the exact pack contents, dimensions, and seller notes—many third‑party packs bundle extra carbon pre‑filters which is good value if you plan to swap pre‑filters twice per HEPA cycle.
- Check seller claims against the unit label: many generic listings explicitly reference part 3304899 and list dimensions (e.g., isinlive shows filter dimensions and notes compatibility). If dimensions or orientation aren’t stated, request seller confirmation before purchasing.
- Watch out for listings that omit either the HEPA or the carbon piece; make sure the pack contains the components you expect.
Step‑by‑step replacement (photo plan for editors)
This short procedure is written to pair with five step photos so a reader can complete the swap in one session.
Preparation (Photo 1: unit & new filters laid out)
- Unplug the purifier. Work on a flat, clean surface large enough for the cover and filters.
- Lay out the new filters on clean paper or a towel. Have disposable gloves and a mask available if you’re sensitive to dust.
- Confirm the new HEPA matches the dimensions and shape of the old one (orientation tabs/labels should align).
Open the unit (Photo 2: rear cover removed)
Locate the rear access panel or filter cover. On the Airmega 150 / AP‑1512HH the rear cover typically snaps free when you press the release tabs—no tools required. Set the cover aside with the screws/tabs if present.
Remove old filters (Photo 3: removing old filters)
Grip the carbon/deodorization pre‑filter and pull it out first; then slide out the HEPA filter. Tip the HEPA away from your face—if it is heavily loaded with dust, consider bagging it immediately for disposal.
Install new filters (Photo 4: inserting new pre‑filter then HEPA)
Insert the carbon/deodorization pre‑filter first (if the new set uses a thin carbon sheet, place it in the same orientation as the old). Slide the True HEPA filter into the main slot with the printed side or arrows facing the same way the old filter did. Ensure each filter seats flush and there are no gaps.
Close, reset, and quick test (Photo 5: reset button / unit running)
- Reinstall the cover until it snaps into place. Plug the unit back in.
- Reset the filter‑change indicator according to the manual: most units have a filter reset or indicator button—press and hold until the indicator resets (consult your unit manual if unsure).
- Run the purifier on low for a few minutes to clear any loose dust and confirm normal fan sound.
Troubleshooting & practical tips
- If the unit displays a persistent filter alert after replacement, power‑cycle the purifier and repeat the reset procedure; if it persists, verify filter orientation and seating.
- Do not wash disposable True HEPA filters. Washing can damage the media and void any performance claims.
- Keep a spare carbon pre‑filter on hand: because the pre‑filter life is shorter (~6 months), third‑party multi‑packs can be convenient.
- Dispose of used filters in household trash unless local regulations require special handling for heavily contaminated filters (e.g., wildfire soot or chemical exposure).
Where to buy (short affiliate note)
Common merchants carry both the Coway OEM pack and vetted generics—Amazon is a frequent source for both OEM and third‑party replacement kits. When purchasing, verify the listing shows compatibility with AP‑1512HH / Airmega 150 (or references part 3304899) and confirms the pack contents you need.
