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

Not sure how well its doing as I just started using it but I can tell that I wake up with less congestion and sneezing so yay! Looks like Im on a successful path!

Until you use this hepa filter! I’m amazed at how well this works, how it automatically turns up or down based on air quality, how quiet it is at low setting, and how quickly it cleans the air! Very user friendly product, very happy so far! I can see why NY Times Wirecutter recommended it so highly!

You can just tell the air is clean. Its in the master bedroom, approx 300 sqft. I am allergic to a dog we got for the family after having dogs most of my adult life prior to having kids. Immune systems change....so this thing helps during sleep and when in the bedroom in general for my eyes. I have zero respiratory problems when in the bedroom as well, not stuffed up at all, but I will preface by saying I dont really have any breathing issues in other rooms the dog is allowed in either. So do not take my word on respiratory quality after purchasing. I used to have dogs as I said so somethings up now and I bought for my eyes solely, another major part of allergies and what hits me the worst. I have eye issues in the house in all other rooms if in them too long, except when spending lengthy time back in the bedroom and of course sleeping. One might think its obvious that sleep is okay even without an air purifier because you close your eyes, but if you know, you know. Without, if your eyes bother you, theyll physically hurt even when closed sometimes, all the way to wanting to scratch the daylights our of your tear ducts during the day. And then when you wake up without better air in your bedroom in this case, youll end up with puffy eyes and massive eye crust, way more than a nights sleep without exposure to the clean air. ALL GOES AWAY WITH THIS. I even have high cathedral ceilings in my bedroom. Starting at 8ft on one side with a pitch to well over 14ft in a room that is just over 300sqft. The auto mode seems effective even for the added cubic feet in the room (remember CADR rates are based on 8ft ceilings), but my wife doesnt like it when it kicks up to medium sometimes while sleeping. It does work though, the dog will literally come in and sleep on the floor at times...and wouldnt you know..Mr. Mighty mitigates her footprint in the air. Run it on high during the day and change the air over as often as possible in a bedroom when no one is in it if its too loud for you and it will be more than effective even if just permanently set to low at night instead of auto unless youve placed it in too large a room. It is too loud on high. High is like sleeping in a hotel room in a humid climate location where they let you change the thermostat temp, but the fan is ALWAYS programed to be on. If you cant deal with that kind of white noise, then do not plan on using this on high when present. It can be barely heard on low and you cant even tell its on. Medium is certainly tolerable depending on your tastes. Easy to clean pre-filter. Put a quarter over the air sensor light at night if it bothers you, its the light, not the sensor itself. Hope the HEPA filter last a long time. It should, my dog doesnt shed and I have mine sitting on a wide dresser at the end of the room across from the bed for a reference point to the distance, placement and noise factors. Perhaps if you are looking for this for a pet that sheds, especially a cat of course, then your filter may not last as long as advertised. I get a sense after all of the research that while these are good for pet allergies too, they are designed for folks that have serious environmental allergies, but this DOES work for me for the dog issue with my eyes. Hope this helps someone.

I have been using it for 2 weeks, Eco mode. Working well, and quiet. The only thing I do not like is the blue light is very bright, and bothers me at night. I covered it to make it less bright.

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.

What I love: this does what it says it will do, the LED light turns off at night, and you have a lot of options on the settings, timing, sensitivity, and speed. What I wish: that it were smaller and cheaper, but cest la vie. Good stuff.

Been using for about week in a bedroom, works well, mostly just leave it in auto mode, detects quickly and filters room quickly, very quiet at night on speed 1.
