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

When I first turned it on the room, red, dark purple, indicating the room was polluted after four hours of running on high, the light is now blue.. fan on high is extremely noisy. Fan on low is OK and I had no problem sleeping.

I have two cats and a corgi that sleep with me at night. I keep this purifier in my bedroom between the dog bed and the enclosed litter box about four feet away. The window is almost always open unless it’s very cold out, so a lot of pollens get in, too (especially with this year’s super blooms!). I can’t believe how much this thing catches! Not just the loose pet hair, but the really fine dust as well. I love how quiet and compact it is. My dog is fond of “fluffing” his bed and blankets before settling on them, and the air quality sensor kicks into high gear automatically to catch the fur and dander when he does. He also likes to lay directly in front of it and feel the air flow as its drawn into the lower intake opening. I’ve had this a few months now and am very pleased with the performance. I clean the prefilter and carbon filter about every month and a half; the photo shows just how much accumulated.

I bought the Coway after researching top air purifiers - I have 2 cats that shed and dust seems to build up very quickly these days. The eco mode is my favorite as I can just set and forget that it is on. It is very lightweight and has a handle that makes it easy to move around as needed. The design is so that changing the filters will be easy.

Bought one for my open plan downstairs, made a noticable difference immediately. Ive since purchased two more.

I like the eco mode best where the filter senses the air quality and only turns on when the air quality gets bad. I can just leave it on eco mode and not think about it again. Highly recommend!

I bought my Coway back in October of 2019. At the time we lived in an apartment that was right outside a freeway and our air was disgusting. After getting the Coway, every two weeks Id end up having to vacuum a significant amount of soot off the Coways metal screen filter and the carbon filter. Before using the Coway, it was easy to see (with a flash light at night) how much stuff was floating in the air. After using the Coway, the air was clean. The unit ran on the medium setting basically 24/7 for 3 years before we moved to a nicer place with cleaner air. By the end of that 3 years, the unit was pretty gross with dust built up on the exhaust grill and right inside of it, and after the move I partially disassembled the unit and gave it a very thorough cleaning and its as good as new. I figure this unit will last for the rest of my life at this point, seems like a solid and extremely effective model and the high price was definitely worth it. This is a great unit if you have dogs that shed. It picks up a lot of hair on its own just running in your home, but its most useful when brushing my dogs. Lying my corgi right in front of it, turning the fan on high, and using a furminator to remove his loose undercoat... the hair removed just gets sucked right up into the Coway and is held there until the brushing session is done. No real need to vacuum the floor after, and such easy clean up! Cant understate how great this is.

I just bought my second Coway Airmega - because Ive had the first one for 5 years, it still works great, and I needed a purifier in another zone of my home. This time around, I needed something for my office. The microphone I use for calls somehow picks up pretty minimal background noise - but this purifier is perfect. The 1st level is nearly silent, and level 2 is quieter than our bathroom fan. I typically put mine on level 3 to sleep, because its really good white noise. I really like that this model uses a pretty big air filter, so it catches a lot. Every time I clean the filters or replace them, Im impressed by what it picked up. The ONLY downside to this air purifier is the notification light on the top - theres an indicator light that changes colors depending on air quality in the room. When trying to sleep, its pretty bright, so weve covered the light with tape. Other than that... its so nice, I bought it twice! TLDR; if you want an air purifier that packs a punch, but also has a super quiet setting, stop looking and buy the Coway Airmega!

Just received this and it’s working well so far. Four stars because this was meant to replace a fan in the bedroom that is used for white noise while sleeping. There are only three fan speeds, and there needs to be one more between 2 and 3. Two is very quiet, almost imperceptible. 3 is very loud with a continuous high-pitched whine in the background. We’re going to keep the Coway for air purification, but we’re having to keep the white noise fan as well. Not quite what we had hoped.

UPDATE: Yesterday our backyard door was unintentionally left open. When I found it, our neighbors had already gone through their dose of nicotine and it smelled like they finished it in our house. Fantastic. I closed the room off (165 sqft), cranked the fan speed to 3, turned the ionizer on, and set the timer for 1 hour. After 2 hours (vacating the area for an equal time as the ionizer is used) I walked in and the lingering smoke smell was no more. Original: First Id like to point out that the manual does not give any instructions about the ionizer. What it is for, when to use it, how it can be harmful in some situations - nothing. The only reference is showing where the button is. I stumbled across this information before purchasing and bought the Coway AP-1512HH because there was a switch for the ionizer. However, I did expect some instructions as to when and how to use the ionizer to minimize harmful side effects. Please research this before purchasing if you have respiratory problems or using this around babies. You CAN use the ionizer option safely, but should not be in the room (or house for extra measure) while in use and for the same amount of time after it has been turned off. With all that said, I am still very pleased with this purchase. I bought it over competitors for 3 reasons. The first is the option to turn off the ionizer. Most air purifiers do this however but the switch meant I could compare it to non-emitting filters as well. The second is the cost over a 4 year use. After years of use, the savings after totalling up filters and product was $100 at a minimum. I compared it to Winix 5500-2, Levoit LV-PUR131S, and Honeywell HPA300. Winix filters are very expensive and cost twice as much as the Coway after 4 years. Honeywell was on the other end of the spectrum but the upfront cost of the product kept it costly. The third is the noise level being 3 dB lower than the rest. I plan to use it around my newborn, so this became a factor. This is not to say the other products are loud. The fact it lined up with the cost layout simply provided more reason to purchase it. Even at the 2nd fan setting, I kept checking with my hands if it was actually running. It was and it did not disturb my wife nor I throughout the night (set up 2 ft away from the footboard). Now my anecdotal evidence for its effectiveness has to be understood and taken as that - anecdotal. One night of sleep is a terrible data set. But I felt such a difference the next day that I wanted to share right off the bat. I had the Coway running for 3 hrs on the medium setting (ionizer off) before we went to bed. For the past weeks, I have been waking up with irritated eyes and a very scratchy throat (NOT COVID). I actually would wake my wife up throughout the night when scratching my throat in my sleep. After 7 hrs of sleep, I woke up with barely a scratch in my throat and my eyes were totally fine. All other factors remained the same, so Im impressed with the change literally overnight. My next steps will be to run the filter before leaving for work and a few hours before we go to bed. Will update the review if anything significant changes. TL;DR - Add to cart. Research if ionizers fit your need before turning the option on.

A very nice product. Looks great and is very quiet except on high which really moves a ton of air. Most importantly, it works! I have several allergies including, unfortunately, a minor allergy to my dog. Since using this product, I notice a very substantial difference. I used to wake with stuffed sinuses and something’s a bit of breathing trouble. After two weeks, these symptoms were fine. I never believed HEPA filters could work on a room scale level, I was wrong. Room is about 300 square feet with 9 foot ceilings. Works great. Completely happy with this purchase.
