   Astoundingly effective, whisper quiet, highly recommend.
   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.

   Best room purifier in this price range!
   Absolute champ when it comes to air purifiers in this price range, and possibly even when compared to much more expensive models. I’ve had several room purifiers from different brands, and this is the best and most efficient. The build quality is also fantastic. Very easy to change the filter, almost instantly removes odors, and operates very quiet. Bought two, and is the only one i recommend to friends/family.

   Clean Air Ninja
   My home backs up to open fields and while it affords a beautiful view, the year round dust and pollen is problematic. I also have two Boxers who shed like it’s their job. So between the dust, dander, pet hair and pollen I developed adult onset allergies. After trying several highly rated air purifiers, and much research, I ran across the Coway AP-1512HH in early 2015 and decided to give it a try. It was the best decision I could have made.1. The Coway is highly effective. During the spring when pollen counts are highest, the unit keeps my indoor air noticeably cleaner. I rarely need to take OTC allergy meds, and my dogs no longer have watery eyes.2. On low setting, the Coway is silent. I have two units running now on opposite ends of a really large open family room / kitchen space and I can’t hear them. On its’ highest setting, the Coway is about as loud as low/medium settings on other brands that I have tried. I never have to turn up the television volume because of this unit – which was not the case with other brands.3. Economical and durable. My first Coway purchased in early 2015 runs 24×7 365…I only turn it off when I’m leaving town for a few days or longer. It runs flawlessly and performs today as effectively as it did when I first purchased the unit. In addition, I have been unable to detect any measurable increase in my electricity bills.4. Auto setting works well – increases fan speed when a change in air quality is detected. For example, if I open the door to the backyard frequently within a short span of time, the unit picks up speed, clears the air, then returns to low when the air quality improves. The Coway also has a sense of humor – ramping up to the highest setting about 10 minutes after I start cooking. And now, with two units running, BOTH seem to take issue with my culinary skills simultaneously. Humph…5. Maintenance is easy. I vacuum the pre filter once a month – it takes two minutes, and I am constantly astonished by the amount of dog hair and dirt it collects. The carbon filters should be changed every 6 months – I flip mine once after 60 days, then replace at about 4 – 5 months depending on how dirty it is. HEPA filter should be changed once a year, and so far, that has been the case for me – probably because I diligently maintain the pre-filters. I found an after market compatible brand of carbon filters on Amazon at a much better price than the Coway replacement kit – which is why I don’t mind changing the carbon more frequently than recommended.The only “complaint” I have is that the air quality indicator light is about the size of a quarter and bright enough to send a signal Mars. I had to cover the light with several layers of blue painters tape then use a black marker on the tape to block the light. There is no way to change the light level setting on the unit.This is an excellent air purifier – the best of many that I have tried. So effective that I now have two in my home. Well worth the price – highly recommend.

   PC – December 19, 2025

   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.

   I purchased the Coway Airmega AP-1512HH(W) for my son, who suffers from seasonal allergies and dust mite allergies, and I can’t say enough good things about it. Within just a few days of using it, we noticed a significant improvement in his symptoms -less sneezing, better sleep, and far fewer allergy flare-ups.This air purifier is quiet, powerful, and incredibly effective. It quickly clears the air, and I love that it automatically adjusts the fan speed based on air quality. The filter system is excellent, and replacing filters is easy and affordable.It’s now running almost all day in his bedroom, and I honestly can’t imagine being without it. If anyone in your home struggles with allergies, this is an absolute game changer. The Coway Airmega truly delivers on its promise of cleaner, healthier air!

   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 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!
