CowayAirmega 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

Finally got to put this to the test as my area experienced some very smoky air. My eyes and chest would burn when I went outside, but inside with this on I was 100% fine. I'm extremely sensitive to bad air, so if I'm doing well then you know anyone will be okay. It's also great for day to day use as dust and allergens naturally builds up in the air of indoor spaces. If I'm feeling snuffly, turning this on helps me breathe easy.The lowest setting truly is whisper quiet, you can run it all night around the soundest of sleepers without anyone even noticing any noise. The highest setting is the opposite, quite loud, but it's good for if you need bad air cleaned ASAP. Don't think of the speed settings as "low, medium, high", think of them as "Silent mode, normal, MAXIMUM OVERDRIVE."Some people like ion mode, some people don't. There's an easy on/off button for that here, so whatever you like this air purifier will do it for you. The fact that it takes a standard filter size also makes it very versatile. A big problem with air purifiers is that if they take a weird custom size/shape of filter, it's nearly impossible to find proper replacement filters. For this, you're always going to be able to find a replacement to fit into it no problems.The only less than ideal thing about this is that you can't run this right next to sensitive electronics. It can create interference that might upset delicate electronics like computers, so it needs to be at least a few feet away from anything of that sort. That can be difficult in a small space. I haven't had any problems with my 'dumb' electronics (microwave, non-smart TV, remote control, that sort of thing) being neighbors with it though.

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.

This product is the real deal. Worked great at eliminating smoke smell from cooking or outdoors. We have a sensitive smoke detector and this product has successfully stopped it from sounding off scaring everyone in the house should we forget to turn on the hood fan. No more grass smell or outside odors coming into the home. Easy to use and very functional. Love the economy mode saving electricity, and the option to switch to Hepa or Odor mode too. Easy to move from room to room. I’m pleased with this product.
