Coway Airmega AP-1512HH True HEPA Air Purifier with Air Quality Monitoring, Auto Mode, Timer, Filter Indicator, Eco Mode

I purchased this air purifier in June of 2018 after it was clear I had to do something with the air quality due to frequent fires we have had in Southern California. It works really well during the last almost to be two years. I have not turned on ionizer because I was not clear whether or not it would be harmful and I left the question for the future. Now however, with covid-19, and being inside all the time, and hearing conflicting messages whether or not covid-19 is airborne or not, except it could be spread from the human droplets and other human fluids. The question what we are to do if we are outside, it is windy, six feet is no guarantee we cannot be affected by the infected person complying with the six feet distancing. So being afraid to open the windows and air the house out, I kept the window closed except late in the evening I left them open, each room separately up to an hour each to prevent any draft. I love the fresh air. After a long time not using an ionizer, I decided to try it on. At first it was pleasant, and even generated a slight scent, which was okay but leaving it on for longer, I have mine on auto settings, with one cat in a household, works really well, the scent became heavy, almost nauseating. Dont get me wrong, this is still an excellent product, at least it worked out for me so I am giving it a five stars alll the way, and I agree with all the other reviews having a good experience. The question of an ionizer is not clear to me though since the numbers do not mean too much to me. For the Coway manufacturer, it would be good to explain more about the ionizer installed in this unit, whether or not it generates an ozone which would be dangerous to human, and animal health, and how long we should leave it on to avoid the heaviness that I started to feel/smell. I went on to a google, and researched how long should one leave the ionizer on, and the answer is no longer than five to eight hours. So there you have it. Once I turned it off, the smell was quickly gone, and I left the air purifier continue its quite performance. I had a feeling leaving the egg spread bowl open, it left the after taste on the spread as well, after the ionizer was already off or was a little bit residual in the air still, hard to say but lesson learned, not to leave it the ionizer on for more than five to eight hours. I looked everywhere in the attached booklet that came with the unit but found nothing specific about possible ozone and recommended duration for an ionizer without feeling the heavy ions in the air. The good news is, that according to the google search, ozone smells like a chlorine, and the smell I had was nothing like that, so I am just hoping this ionizer does not generate ozone. It would be nice to have that comment in the instruction booklet. Thank you.

I read all the other reviews and was motivated to buy this particular product and I am VERY GLAD I DID. It is so quiet and I can feel it working which is great!!! The packaging weighs a lot more than the actual product so be aware when lifting it. I simply took a knife and cut it away and then it was easy to move to my apartment. ONE NOTE: I HAD OFFERED THE DRIVER A SUBSTANTIAL TIP TO DELIVER IT TO MY DOOR BUT THEY UNFORTUNATELY (FOR THEM) DID NOT READ THE INSTRUCTIONS COMPLETELY... SO I HAD PIZZA FOR DINNER TONIGHT:) GREAT PRODUCT. WORTH THE EXPENSE!!

UPDATE: We were so impressed we also purchased the Coway Airmega 400, the model that clears up to 1600 sqft in addition to the model I’m reviewing here. These are wonderful air purifiers, our air is so clean. We use the ECO mode on both and they come one and off all the time depending on the quality of the air it samples. ORIGINAL: My cat has severe respiratory problems. She has been seen by veterinarians, respiratory therapists, allergists, and internal medicine specialist veterinarians in multiple states and even with medications she’s still miserable. We dread Springtime. We’ve had air purifiers before which have helped, but not nearly enough …and then we found this one. My kitty’s nose is dry. It’s dry! For the first time in years she’s not heaving, hacking, and her nose isn’t constantly running. She’s sleeping without snoring. And it’s a Spring day! See the picture? She’s so relieved that with the exception of her visits to the cat box, I can’t peel her away from it. She’s even ignoring looking out her favorite window at the birdies. I don’t know why this is so much better than the other HEPA brands, but they’re night and day. We’re going to be buying more of them, no doubt. See her sleeping? This is what relief looks like. ❤️

We dont have proper ventilation in our kitchen and my husband cooks a lot every day so I was worried about air quality. After trying this out for the first time we could literally feel the difference in the air. I no longer suffer from irritated eyes and lungs when hes cooking. Its very powerful and can even combat the smoke from cooking bacon. Also, its super easy to clean. These things do take maintenance but its well worth it for clean air. For anyone wondering about filter replacement costs who doesnt want to do the research themselves, this will cost you about $55 a year for filters. Really not bad at all for how well it works.

Used this yesterday afternoon for the first time. Set it on Eco mode on the sensitive setting. With the ionizer on. Started feeling a lot better with improvement in air quality. Let it run through the night. Woke up with a dry and inflamed sinus. Realized it probably was the ionizer (ozone). So now Im using it with the ionizer off. Otherwise its nice and quiet, and easy to setup. Judging from the previous reviews, it works just as well without the ionizer.

The eco mode and air quality sensor is a nice feature, and the low fan mode is whisper quiet with pretty good airflow. My main complaint is that the air quality light is big and bright and cannot be turned off. You will want to tape something over it if you want to sleep at night.

I dont want to be one of those giddy-with-first-impressions folks in not testing a product thoroughly for months before posting a review... but this thing makes me wanna do just that. It arrived simple & understated.. and by that I mean, unpacking was easy and it did not take brute force or cleaning stray pieces of styrofoam for 30 minutes after unboxing. It slid out, I removed two pieces of protective styro caps, and unwrapped the shrink wrap. I took off the plastic wrap from the filters (which were already in place so I didnt have to read a book of instructions first to figure out where to put them). Then I simply plugged this sucker in, and it worked on auto right out of the box. It was like unboxing an Apple product -- so intuitive, so seamless, so simple. Kudos to manufacturers. And of course, as first impressions go... it looks good. So I love it even more because its pretty. Aesthetics aside, it is also built well... and perfectly sized. I attached photos to show that its not too tall, nor is it too deep. It is a bit shorter than my nightstand, which is of an average height. Its a bit on the wide-side, but you can position it however you see fit. It does need about a foot on the right side to allow for proper air flow, and probably a good idea to keep the front end free & clear since the circle is from where it pulls in air... but I found this guy could be positioned in many places throughout my home without being an eyesore. I have it in my bedroom currently, but I plan to buy one for my family room as well, and maybe the basement also. It really does work. My bedroom is often very stuffy, especially in the winter when we have the heat temperature set to 73 degrees -- I like it warm & toasty, but my nasal passages feel otherwise. I do suffer from pollen allergies, as well as mild allergies to dust mites, grass, ragweed, mold spores, and pet dander (although I still have 2 shed-heavy fur-babies.) But my allergies are never bad enough to warrant any real attention, I just suffer through it since theyre pretty mild. HOWEVER, I keep saying mild when in all reality, I didnt know the difference between no allergy and mild allergy until sleeping one night with this purifier running. Man what a difference. My nose was not all dry and cracked up feeling on the inside. It also was not runny or scratchy, which is how it often feels after running my humidifier all night (which I run to keep my nose from feeling so dry!) This machine does not mask the issue, or dampen it, or freeze/cold draft it away.... it CLEANS THE AIR. I know, I know... its hard to imagine, but boy is it easy to feel. I slept for the last 2 nights like a newborn baby. Granted, Ive only had it for 2 days but the difference from walking into my bedroom vs the other rooms of my home, cannot be ignored. My home isnt particularly old, or stuffy, or dirty, or dusty. Yes we have pets, but I am a Dyson maniac and we have a brand new HEPA HVAC filtration system; we have our ducts cleaned regularly; and, there are no smokers or other reasons for contaminated air (at least that I can find.) However, when plugging this thing in... it ran a blue and then purple light for a bit on auto, but then changed to RED (which freaked me out a bit as it sounds rather aggressive). And it ran that way for about 10 minutes. I left it to its job, and when I returned a little while later, it was back to a blue light and I could barely hear it running anymore... but the air did in fact feel lighter, crisper, and easier to breathe. It felt much like the very first time I walked onto my hotel balcony in Vancouver, Canada and took in a giant breath. It just felt... clean. Air quality is a legitimate thing, and having poor air to breathe makes life a less tolerable for people with allergies or lung issues. Again, not something I suffer from necessarily, but I appreciate the cleaner air this provides nonetheless. So I cannot imagine how much better breathing could be for someone that does have serious allergies, asthma, or other breathing troubles. I would say this gem is a no brainer, if you do. But even if you dont, youll still notice the difference after plugging this guy in and letting it run for about the first hour. I do think the auto feature could become a bit of a power monger as I have never witnessed it turn off after being on auto as if to say okay, Im done. All clean. So I do set the timer feature when Im not going to be upstairs and I shut it off when Im leaving the house for awhile. Another thing to note is that there are studies about potential harmful effects to lungs when using the UV and ion cleaning features. It is recommended that you only use these settings when not in the house as breathing in UV treated air is said to be harmful as a result of O3 air, similar to breathing in air high in ozone levels. So I only set my purifier with these features when not in the room. I cant yet speak to durability or filter tolerance, but they are priced reasonably enough that changing once or twice a year would be totally acceptable. I will update if I find that longevity or level of purifying impact worsens, or if cleaning/upkeep isnt as great with this machine moving forward, but for now... I am a Coway air purifier believer. ** UPDATE - after 7 months of constant use, I will say that my initial reactions were still pretty accurate in that this purifier does do what it claims to do. I notice that it is reactive to smells, smoke and other air-purity issues when they are occurring, even when I am simply cooking sausage or something extra smokey or fragrant in the kitchen -- while I have this unit upstairs in my bedroom, which is a considerable distance from the kitchen (bedroom in front of the house on 2nd floor, kitchen in the back of the house on the 1st floor.) So I know that it indeed works because I can hear it begin to run rapidly when I accidentally burn something or even when making bacon or something that has a smell or odor. I also know that it is filtering dust and pet hair, because both of my Coway purifiers (I have one upstairs and the tower unit downstairs) needed HEPA filter replacements at 6 months. The manufacturers suggestion is 6 months for the carbon odor filter, and 1 year for the thick, HEPA filter.. but my HEPA filter was so dirty at 6 months that the change filter light came on for the tower unit, so I figured I would change this 1512HH unit at the same time, and it definitely needed it. The filters were both clogged with so much dirt, dust and pet hair.. I couldnt believe this stuff was floating around my house for it to grab. In fact, even strands of my hair were in the filter! And my hair is pretty long, well below shoulder-length. I figure it must have sucked it in from the floor. Pretty cool purifier... I still give it 5 stars and 2 thumbs up after 7 months of use.
