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

I had some neighbors complain about the hall smelling like the Chinese food while we cook. So I figured I would try this out to see if it helps. I just received it and set it to auto. As soon as she started cooking the machine turned in high. Then went back down to level 1 shortly after. I could noticed a decrease in oder while she was cooking. I don’t know if the hall way smells, but at least my home doesn’t have the smell like it usually does while cooking. Also, it’s nice to know it is working awesome to circulate the air. First day and I’m pleased. We’ll worth the money. I’m sure our allergy symptoms will improve as well in a few days.

After reading reviews in wirecutter and on Amazon I thought it would be a worthwhile purchase. Having it for only a few days, I would recommend this for anyone concerned with their breathing comfort. I was amazed at quickly it turned to right speed when sensing smoke from cooking in the kitchen. And no sooner was the smoke gone, it turned itself back to low speed. Very quiet and looks good while doing great job.

It works great. Very efficient electric consumption on the Auto mode. The multi-stage filter is awesome for pet hair. I clean my pre-filter and charcoal every week. The HEPA filter unfortunately didnt last much past 4 months, but it catches a lot of stuff from the kitchen and we do not have a hood at the stove.

Bought one for my open plan downstairs, made a noticable difference immediately. Ive since purchased two more.

The auto feature is wonderful as it operates at a near-silent level most of the time. With allergies prevalent in the family, we’ve noticed a true difference in interior air quality.

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.

Im not sure how this is so highly rated. Although it does work, more or less, for the price it really has many issues of poor design. Some of the features you are paying for are useless because of the way they work. 1. The Air Quality Indicator is useless. It stays blue (meaning good) even at readings that are clearly high on my 2 separate Air Quality meters. For example, with an AQI of 90 and PMI2.5 of 35 (both of which are definitely too high and cause problems for my asthma), the indicator on this unit still shows that the air quality is good. From reading other reviews, I think this is a design defect and not just a one-time faulty unit. 2. Because of the problem with the Air Quality indicator, that makes the Auto and ECO modes useless as well. If I turn on Auto, it just stays on low fan speed (which is very, very low) all the time. And on ECO mode it seems like it would just never turn on, although I didnt test that extensively. Apparently the air quality would have to be pretty severely bad for this unit to register that its out of the good range. Whereas I need something to try to make the air quality as good as I can get it, not something where a moderately bad air quality is considered good. (There is a sensitivity setting for this indicator, and I had it set to the most sensitive setting. So the issue would be worse at the medium/ standard setting.) 3. The Fan speeds dont make any sense, meaning manual operation of the speed is also problematic. Speeds 1 and 2 are both quite low and dont do much. Speed 3 is then a very large amount of air moved and very loud. In other words, speed 2 is not in the middle between speed 1 and 3. Its much closer to speed 1, and then theres a big jump from 2 to 3. So I guess it would work if you wanted to manually leave it set to Speed 3 100% of the time. Otherwise, there is no speed that meets what I need much of the time, which is a middle speed. Again, after digging deep into other reviews and customer questions, I did see someone else reference this, so its not just a one-time defect in the unit I received. 4. Other misc notes if you do decide to buy this - The Air Quality Indicator light is very, very large and bright, lighting up the dark room when I tried to sleep. Although the user manual doesnt mention this, you can hold the Ionizer button down for 3 seconds to turn off this obnoxious light. - Moving and unpacking the unit as shipped could be problematic for some people. The Coway box it ships in is fairly large and bulky, about 20x22x13, so quite a bit larger than the unit itself. So although its not really heavy, if you have short arms and have to move this anywhere before unpacking, it might be a little difficult because of the bulk. It also means you have to be able to lift it almost 2 feet to get the unit out of the box (theres an inner box that is a very tight fix inside the outer box) or turn the box over. So again if you have short arms or have any strength limitation issues, the unpacking might be a bit of a problem for you even though its not super heavy. Also note that the AC power cable has plastic tightly wrapped and taped around it, and there isnt any way to get it completely off without cutting. That could be dangerous if you accidentally cut a little bit into the AC cable while trying to get this off, so please be careful. Its also difficult to remove the plastic bag on one of the filters without cutting, so you do need a knife or scissors to unpack and set this up. Overall, Im not happy with this at all and am going to buy something else. Update: I decided to give this one more chance. After trying it again, two further observations: - Even with an AQI (on my separate monitors) of close to 150, and PMI2.5 of around 50, the air quality indicator on the unit still shows blue = good on the most sensitive setting, so the auto mode still wont kick up being the lowest level - The unit has started making a whining noise, in addition to the normal fan noise. The whining noise, while not incredibly loud, is more obnoxious and annoying than the white noise of the fan, because its more of a constant tone.

Definitely breathe more comfortably with this bad boy by my bedside.

Really like the noise level. have been using it on ECO and only comes on when needed. the air quality is much improved in our bedroom. I had developed allergies to our cat and these are much improved.

Love this air purifier! Works great and has different settings and easy to clean. I have 2 small dogs and since air purifier have noticed less dog hair on floor between vacuumings. The first filter in purifier I vacuum if there is hair on it. I have also noticed less dust on furniture and our windows are open.
