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.

I’ve had this for about 1 year and 4 months now, and it is WORTH ITS WEIGHT IN GOLD. I’ve researched and tested a lot of air purifiers, and this one is by far the most effective for everyday living. Setup & Design Setup took less than 5 minutes — just unbox, pop in the filters, and it’s ready to run. Performance & Odor Removal The HEPA filtration and air quality sensor are excellent. I have a sensitivity to smells, and this purifier clears out odors shockingly fast — my roommate’s strong odors or cooking smells are gone within about 60 seconds, no exaggeration. The air feels cleaner, fresher, and lighter within minutes of turning it on. Noise & Everyday Use On the lowest setting, it’s whisper-quiet, perfect for sleep or background use. Medium and high are noticeable but not disruptive, especially given how much air they move. Auto mode reacts quickly to changes (like frying food or candles), and Eco Mode shuts the fan off when the air is already clean, saving energy. Filters & Maintenance The pre-filter catches a lot of dust and hair, and it’s easy to clean. Filter replacements aren’t the cheapest, but they last 6–12 months with regular vacuuming, and the filter indicator takes the guesswork out of when to swap. Value For the price, it’s a great balance of performance and cost. It easily handles medium rooms, and unlike some “smart” purifiers, the features here actually work as promised. Overall: If you’re sensitive to odors or allergens, this purifier is a game-changer. It’s quiet, efficient, and genuinely improves air quality in minutes. The fact that mine has lasted over a year with heavy daily use makes it even more of a win.

We have seven air purifiers in our home and this is the best. We have two cats and a grandson with a cat allergy, so we have air purifiers in almost every room. We also have a dusty and smoky season where we live. We have two of these in the main areas of our 3600 sf home and they keep our air clean. It’s amazing how filthy the filters get, which is gross but grateful we aren’t breathing it! It’s sleek and modern looking. Quiet for the most part - we keep them on auto and they kick up occasionally when their sensors indicate more particles in the air which can get loud but it quiets down quickly. I’ll eventually replace the other purifiers we have with these.

I originally bought this Coway Mighty Air Purifier during COVID when I was spending more time indoors and wanted cleaner, fresher air — especially in my bedroom. It’s turned out to be one of my favorite home purchases. This unit works beautifully for a single-room setup. It’s simple to operate, intuitive, and clearly does its job. I can actually see and hear it respond — for example, when I change my bed sheets, it automatically kicks on because it detects dust and lint in the air. That feature alone proves how sensitive and effective it is. I first bought it because The New York Times Wirecutter had recommended it for years, and I completely understand why. The design is minimal and sleek — slightly futuristic, but still subtle enough to blend into a modern or minimalist space. The odor filter is a big plus for me since I have a dog. It noticeably reduces pet smells and general room odors. Changing the HEPA and carbon filters is quick and easy, and while replacement filters are an ongoing expense, the overall build quality makes it worth it. It’s a bit bulky, but that’s expected with purifiers of this caliber. Mine has been running for almost five years now, and it’s still performing perfectly with no signs of wear or fatigue. If you’re looking for something reliable, durable, and good-looking enough to keep in your main living space, this is an excellent choice. I’d absolutely buy another one for a second room — though if I had the space (and the budget), I’d upgrade to a whole-home system next.
