Coway Airmega AP-1512HH Air Purifier Replacement Filter Set, 1 Count (Pack of 1), White

Seem to be high quality filter

Like many other people who have written reviews about the chemical odor issue. This is what happened to me and what happened after I talked to the manufacturer. 1) I bought a replacement filter from Amazon and like many, it had a strong chemical odor 2) Upon contacting Coway support via email, I told them about the issue and they said that the filters had been exposed to something (no mention of any details on of what or how) but that they did not think it was toxic and that Amazon knows about this so I should ask for a replacement. I had to include a screenshot of my receipt as proof of purchase. 3) I explained this to Amazon support about the issue. There was no mention of knowing about the exposure or the odor but they did send me a return label and a replacement. 4) This second filter still had the odor but was much less. Still concerned, I reached out to Coway again and told them that the issue still persisted with the new filter, described to them a little more about the issue, and provided other information (upon their request) such as my name, address, photos of the filter inside the 1512HH, and the serial number of the 1512HH, and they would consider sending a replacement. 5) I got a replacement from Coway and the filter had a very slight odor but was much, much better than the two from Amazon. However, the plastic packaging around the filter was a little different as it contained a yellow informational tag (with a diagram to remove the plastic), and the plastic packaging had an adhesive flap that one can reopen and close. There were also a few crease marks on one of the sides of the filter itself, possibly from sustaining pressure or impact or from being handled. Im not sure of the exact cause but none of the filters (including the original one that came with the 1512HH had that) have such creases. So, I cant definitively say that this filter was handled in some way to remove the smell before it was sent to me, or if the filter sustained some sort of pressure from storage or shipping, but I can at least say that they were responsive to my concerns and sent me one that barely an odor. Another observation is that the printed identification on the filters are different (as shown in photo). Also, it came in the same box as the filters from Amazon but only had 1 odor filter, instead of 2. The final observation is that I continued to use the second, and less smelly filter from Amazon. I tolerated through the odor because I live in an area affected by wildfire smoke and didnt have much of a choice while I corresponded with Coway and waited for the replacement. I cant say if that was right move in terms of possible toxicity but thats what I decided for myself. The smell did eventually go away, but it definitely takes a couple weeks of regular use/airing out though.

This is the thing we needed. It had the quality the brand carries.

I have three of these units. The thing that I like best is the option to remove the carbon filter. I have found those can create a bad, as well as irritating smell for me and make units unusable. I have 2 of these hepa replacements. Haven’t found a problem with any smell. But, on receipt, the first thing I do is throw away the carbon. I also don’t use the ionizer. Hope this helps someone.

Authentic and economical. I am happy with it

Purchased these as replacements for my Coway air filter. Easy to replace and works as expected.

I decided to pay extra for the OEM version rather than the generic, and I could instantly tell that the Coway brand had thicker pleats than the generic. Working fine.

I really love my air purifier and this filter does its job

* Updated to 1 star as I ordered a 2nd filter set for my other air purifier and seem to have received a counterfeit. This was also ordered directly from Amazon, so buyer beware! Note in the image that replace is relpace and odor is oder. Also noted that the correct filter set has #3304899 in the lower righthand corner vs #3109905 in the counterfeit. The COWAY logo is also the incorrect font. I expect better than this when ordering from the 1st party instead of shady 3rd parties. * Product appears to be genuine OEM replacement filters from Coway. These were ordered directly (sold by) Amazon and delivered on the last day of 2021. The black filters did not have any sort of chemical smell, however the same cannot be said for the HEPA filter, sadly. The HEPA filter had an incredibly intense chemical odor upon removing it from its plastic wrap. I left the filter to sit in the garage for 1.5 weeks before attempting to use. The odor dissipated some, however as soon as the filter was placed in the air purifier and ran, the odor emitted was very strong again. I can only imagine how bad it would have been had I not left the filter to rest for that 1.5 weeks prior. I ended up having to place the air purifier in the basement, running on maximum strength, for 24+ hours. After running the air purifier for 24+ hours, the odor finally dissipated. This type of chemical odor should not be acceptable for a consumer product, particularly one aimed at cleaning the air. I would imagine that if you used this filter directly without a safe place to get rid of the odor, this could potentially be a health risk? This is only my opinion, not an expert (clearly). I would look at finding an alternative solution in the future should reviews reflect strong chemical odors persist.

My original purchase of the Coway Airmega AP-1512HHS air purifiers (I bought two) came with honeycomb frames filled with charcoal filtration beads instead of the cheap mesh replacement set. I want to cancel this subscription, but it does not seem intuitive. One air purifier seems to run red all the time, suddenly, indicating poor air quality. We havent changed anything in the environment. I swapped units, placing them in different rooms, and the one was still going red all the time despite the room change. I think something is wrong with it. I bought both in January, 2022. The one that indicates the red light nearly all the time smells like its burning when it runs. I have cleaned it and changed filtration. Nothing helps. The other one seems to perform fine.
