Coway Airmega AP-1512HH(W) True HEPA Purifier with Air Quality Monitoring, Auto, Timer, Filter Indicator, and Eco Mode, 16.8 x 18.3 x 9.7, White

I bought a $90 tower purifier which took a long time to clear the air and which was noisier than a jet engine. I lived with it, but when the Canadian wildfire smoke descended upon us in NYC, I loaned it to my downstairs neighbor, who had elderly and special needs family members, and I ordered this as a replacement. It's more than double the cost of the other unit, but based on the reviews from the New York Times and other review sites, the quality and performance are well worth the investment. So I splurged and got this unit. While I was waiting for it to arrive, the air pollution got really bad and I had been coughing, eyes were watering and I was forced to wear an N-95 mask at home just to breathe. When the purifier finally arrived, I turned it on and the sensor light went red to indicate the high level of contamination in the air. I opened the doors of every room of my apartment to let it go to work and after a few minutes at full power, the light turned from red to purple, and about 5 minutes later, it went blue. I took my mask off and the air was pure and fresh. It is an absolute superhero at cleaning a large volume of air very quickly. I was thoroughly impressed. The sensor is very sensitive and will turn purple if you are just cooking something that releases strong scents into the air (sauteeing onions and peppers, etc.) and it goes red if you're burning anything. Another upside is that my kitchen smoke detector has stopped going off if I'm grilling something, because the purifier keeps the air quality under control. At the highest setting, it's about as loud as my old purifier at the middle setting, which is to be expected, as you would only set it that high to quickly clear out a room or if there's smoke from cooking, etc. But the massive volume of clean air it blows out in exchange for that short term annoyance is staggering. However, at the 2nd highest setting it is barely detectable, producing a pleasant, white noise background sound that you quickly tune out. It makes falling asleep very easy, and if you have the air conditioner on you can't hear the purifier at all. At it's lowest setting, it blows out a nice stream of air but is utterly and completely silent. You couldn't even hear it at night time in a small, quiet room with the door shut. Amazing. They say you never regret buying the best. They know what they're talking about. This is worth every penny and then some. 5 stars, all day.

Shopping for an air purifier might be one of the most headache-inducing purchases (that isn’t a house, car, or insurance plan) in existence. So many factors have to be taken into consideration such as room size, the type of filtration, electricity costs, filter costs, noise level, durability, and effectiveness. In my air purifier research, I watched countless videos, read countless articles, and almost pressed the purchase button on countless units. All while growing overwhelmed by the sheer number of recommendations and dishonest manufacturers. After a lot of mind-numbing research, I eventually settled on this Coway unit and am very happy with the decision. I keep it in my 150 square foot bedroom on speed 2 (ionizer off) at all times. This gives me over 5 air changes per hour, and speed 2 only uses 8 watts of electricity (according to my research) so it had no noticeable effect on my electric bill. What it has had a noticeable effect on is the air quality. I find less dust on furniture and none in the air. I don’t wake up congested anymore. The air purifier gets rid of that smell when you just vacuum, litter box odors, and the dust that is kicked up when you clean the litter box. Filters are affordable when you take into account that you only need to purchase a replacement pack annually. My unit has worked well for the time that I’ve had it (and many other users have said their Coway Airmega units have lasted 4-7+ years) so the product seems durable. Overall, I am happy with my purchase and glad that I get to breathe fresher air. I can see why this unit is so highly recommended. It does what it’s supposed to do, and while some may find the design polarizing, I like it. It’s unique and interesting.

This air purifier keeps the air in my bedroom clean, helping reduce dust mites. When it detects disturbances in the air, it kicks into high and runs. When it is on auto, its quiet and doing its job. When the unit kicks on to that high mode constantly, you know the filter needs cleaning. Vacuuming it regularly prevents this from happening.

This air purifier is very quiet and moves a lot of air. I have it in the living area and forget it's on as you don't hear it. It will automatically ramp up the speed when it senses debris in the air, and then shuts off when it's clear (totally not from cooking mishaps). Dust in general seems to be much less, which shows it working. The replacement filters are not expensive, and the energy usage is low. Would recommend.

I bought this one for upstairs because I really like the first one I bought for downstairs. I have zero complaints about the first one. This new one though is noisier. We are keeping it but are a bit disappointed. Other than that, it works great. Easy to use, and filters are easy to replace.

La entrega fue muy rápida, me llegó un día antes de lo previsto, primer punto positivo. El purificador esta hecho de muy buenos materiales segundo punto positivo. En cuanto al ruido en el nivel 1 el ruido no es perceptible y en el nivel 2 es casi imperceptible, en el nivel 3 si se escucha mucho pero son muy pocas ocasiones y por muy poco tiempo en las que se tiene que usar en nivel 3 por lo que también es un punto positivo. Otro punto positivo en mi opinión es su tamaño que es más compacto que otros de su misma capacidad. Yo vivo en una zona donde hay muchas construcciones de edificios en los alrededores lo cual ha hecho que en los últimos dos años haya mucho polvo en el ambiente, además la calidad de aire en la ciudad donde vivo ha bajado mucho también lo que ha provocado que tenga reacciones alérgicas que sobe todo en las noches provocando que se me congestionen las vías respiratorias y batalle para respirar. Las 3 noches que llevo usándolo hasta ahora el nivel de polvo en la habitación a bajado casi en un 90%, no he tenido reacciones alérgicas y en las noches no se me congestiona la nariz, lo tengo encendido las 24 horas del día en el nivel de velocidad 1. Todavía es pronto para ver si tendré buenos resultados a largo plazo pero hasta el día de hoy ha sido muy bueno. A los que están investigando la compra de un purificador de aire les recomiendo que analicen muy bien su situación particular. Este purificador me ha sido muy útil ya que elimina polvos, olores y la gran mayoría de contaminantes, también por lo que investigué elimina solo parte de los gases emitidos por los automóviles en zonas de tráfico pero cuidado, no los elimina del todo, si tu vives en una zona de mucho tráfico vehicular y necesitas eliminar los gases producidos por el tráfico necesitas otro tipo de purificador. En mi caso particular ha resultado excelente compra y si lo recomiendo, estoy por comprar el segundo para la recámara de mis hijos.

Compré este purificador de aire que al principio me gustó, realmente es muy silencioso, solo que después de usarlo solo 2 meses ya me dice que cambie el filtro. Por qué? Se supone que hay que cambiarlo después de 6 meses...y eso que solo lo usamos durante la noche...realmente decepcionante...

I'm not commenting on the specs as I'm not qualified to, I hope it matches the specs. Wirecutter says this device is "quiet enough to sleep near". This device when operated on low fan speed is indeed very quiet, but if it's operated on auto mode (as it should be for optimal performance) it will change fan speeds as required and the first night it woke us up. Our bedroom is on the second floor and I can hear it on the main floor when it changes speed. We had originally planned to buy 2 units, one for the bedroom and the other for our family/living room. But we bought one to try it and we won't buy another! When it kicks into auto mode it's loud enough to disturb conversation and TV watching. Oddly the device has lots of lights on it (not sure why it's necessary), but it also produces far to much light for sleeping. I've attached a picture of the device at night from our bed so you can see the glow (while not exact it's a good approximation, think 2 iPhones on). The light is a bit annoying for us, but we can live with it, but if you are used to complete darkness then this is not the unit for you. I've also included a video with sound so you can hear what the device sounds like when it kicks into auto mode. I'm using an iPhone 14 about 3 feet away and on my phone if I turn the volume upto max and play it then it gives me a realistic approximation of the sound.

I got this as we have pets and I have asthma and I am allergic to dust, spores, scents e.g. It came very carefully wrapped from the boxing of the product to the individual filters all in protective packaging. I turned it on and straight away it detected cooking smells and on Auto it started up and turned itself off when air went from red to blue. For those saying it doesnt work … did you take all the wrapping off the filters? Its a modern design and fits nicely against a wall. The air felt so much fresher this morning ( we live near to the sea so home has a sort of beach hut smell generally and close by trees blow pollen in) It clearly removes spores as I didnt have my usual sneezing fit this morning having left it on auto over night.

Opened the box a and followed all the instructions to remove packaging etc but it never worked. After switching on the power butter the speed buttons flash and then I’m not able to click on anything else. It doesn’t turn on at all. And very unhelpful customer service so have not been able to return the item!
