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

I was concerned, of course, because of the many reviews talking about a toxic smell. No toxic smell on mine. It smells like every other HEPA replacement filter Ive bought in the last 20 years from many different brands. Tested once with my dylos particle counter. I am getting about 30 ppm ambient indoors (after running these filters for a couple of days) and 3 ppm of 2.5pm at the exhaust (0 to 1 ppm of pm 10). 30 ppm is already very low, the outdoors is generally well over 1,000 ppm on my dylos meter. With the Canadian wildfires the ppm outdoors has been routinely over 5,000 ppm of pm2.5 and I even saw over 12,000 one day. Ill update when I get a few more readings. Im very happy with Coway so far, its a high quality and quiet machine with good filter replacements.

We purchased 2 of these back in February along with two other filter replacement packs. The latter were specifically for the Coway Air Mega 150W (of which we have 4 in our home). Due to limited availability of the correct 150 replacement packs we were told by Coway that these AP-1512HH filters could be used also in the 150. Well ... sadly, that is not the case. Perhaps this is our own fault for waiting until spring to actually swap out the filters ... and now we are beyond the return window. Either way, identifying the correct filter for a particular Coway model sold not be as difficult as it is. Now we have 2 of these things that are quite useless.

* 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.

Replaced both filters and cleaned my air purifier in less than 5 minutes. The replacement filters were a perfect fit.

Ive tried the generic versions to save money, but the Coway replacement is the only one that snaps in easily. I feel more confident that air is being efficiently filtered. Im very sensitive about odors and the Coway filter has no odor of its own, and does a great job cleaning the air.

I should have taken a photo, but after ordering and installing my second replacement filter I can say this isnt a bad deal. The air purifier this goes in is a good setup for home use and the ability to tune its speed to air conditions is excellent. I however had mine set to the medium (2) speed every day, 24/7 for 6 months. And it was still able to filter air through. The old filter came out weighing three times as much as a new one and was nearly as dirty as a lint trap in a dryer! The carbon filters do an excellent job catching cat hair and large particles allowing the Hepa to catch the finer things! So long as you keep the carbon filter cleaned at least monthly the hepa does an excellent job with air quality of your area! Im Completly satisfied and sold on this product line and replacements even though I know I could DIY hepa filters for less $$$ these work so well I dont want to!

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.

Was happy to open the package and get the exact OEM filter when purchasing my Coway mighty along with 2 additional prefilters. I did read some reviews stating the filters had an awful smell to them, mine did not so that issue must have been resolved.

Great purifier. Can most certainly notice a difference in the air!

I was a little nervous buying this product after reading some of the reviews about the smell. However, I needed replacement filter because the one came with the purifier has turned black after 8 months of used. I am glad that I gave it a try. The replacement filter has NO SMELL as some of the reviews indicated. It works great. I would recommended the product.
