    • Very impressed!
Style: 400 White
Due to my allergies being worse than usual this year, decided to do an air quality overhaul on the home. This included an upgraded whole-house filter on the AC/Furnace (Merv 16), a Coway Mighty unit for the bedroom and this larger Coway Airmega 400 for the rest of our open floor plan. Immediately I notice the build quality of this unit is really nice. Tight fitting parts, nice design details (magnetic doors, for example). Everything visually looks and feels high quality. It is a step up from the Coway Mighty, for sure.. The filters on this unit are impressive. One side is a honeycomb filter media loaded with carbon pellets for filtering out odors, with the other side being the HEPA. Once I had these unpacked, I installed the pre-filters and replaced the exterior covers and got this unit up and running! Operation is very easy and straight forward. I don’t mind the touch-screen style buttons at all, it’s actually quite nice. Buttons are responsive to touch and work perfectly. You have the power button, fan speed selection (with ECO mode) and a button for turning the lights of the unit on/off. Note, at first I thought my power button was broke until I read the short and concise manual which does state to hold your finger on the power button for 2-3 seconds to power off. Worked like a charm! So keep that in mind if you skipped the manual, like me… Oops! Sound level wise, it is practically silent on low. Even sitting right next to it, you can’t really hear it. Medium picks up a tiny bit of volume, but it’s still very impressive how quiet it is. You start feeling quite a bit more airflow at this point, it seems to the be the sweet spot in terms of air being moved and the volume level if you are occupying the room. On high, it’s still honestly not bad but can be a little distracting depending on what you are doing. The sound is simply just air moving, no motor or other offensive types of noise. For those who really like white noise, it’s quite soothing in my opinion! We have a split level with an open floor plan. We have the unit located on our 2nd floor in the corner of the room. The Airmega really pushes air around, you could feel a draft in the other rooms when the unit is on high. Very happy with that, it really circulates the air well. The air quality sensor responds very well to stimuli when the air quality drops. When my dog jumped on the couch nearby, it kicked on to a higher level. When I dusted window blinds on the opposite side of the room, it detected the change in air quality and quickly kicked on high. Even blowing out a candle in the next room, it was detected. Very happy with it’s performance. The air absolutely feels cleaner. Perhaps it is a placebo effect, but there is no denying that this unit is great for removing allergens and odors out of the house. I am very happy with this unit and would highly recommend it! ... show more

    • Worth it

Holy grail air purifier. So easy to use and makes a real noticeable difference. Extremely user friendly and easy to clean too. Also appreciate that it is not a huge eye sore. Very quiet. Worth every penny.

    • air cleaner
Style: 400 White
This was pricey unit however got a good price through Amazon, we have run the unit now for about 3 weeks as noted in some other reviews it runs very quite. This unit was the most recommended on many of the sites I checked on. We have a1,400 sq foot one level condo and thus far we have noticed a difference in the air. It feels cleaner , fresher with less dust. Haven't had any odor issues as of yet so unsure how good it removes any house hold odors. It also looks great and is easy to move if needed, filters are a bit pricey but if they last 6 months or more I can live with that. Good unit. ... show more

    • Simple and effective!
Style: 400 White
Who doesn’t love clean fresh air? I have really bad allergies so an air purifier is basically a must-have, but even if I didn’t have allergies I would still make having a good air purifier a top priority. I sleep better, my apartment smells and feels cleaner, I breathe better, etc. I tried to go cheap twice, and it bit me twice. Before my Coway setup I had a unit that I bought from your favorite home improvement store, and when I went to replace my filter they had stopped carrying the unit/filters. I tried finding the filters online but they were hard to find and expensive for the low quality. Furthermore, it was a cheap cumbersome purifier that wasn’t super effective and was annoying to use. I bought a Coway Airmega 250 (which I still have and love), but I tried to make it my “everything” purifier. I would move the unit back and forth from my bedroom living/dining area as needed, but the living/dining area (roughly 650 square feet) was just too much for this unit. Every time I cooked it would max out and stay maxed out for quite awhile, and it always felt like it was trying to keep up. However, in my bedroom (which is much smaller) It’s perfect! I decided to buy the Airmega 400 for my living area and what a huge improvement! The 400 is more than adequate for this space and I don’t hear it kicking into high gear nearly as often, and when it does it’s much more brief. I now keep the 250 permanently in my bedroom, so not having to drag a purifier around is a nice cherry on top. I am very happy with the quality of Coway products. Both units have a nice heft to them so they don’t feel cheap, the filters fit super flush (they are actually satisfying to install because they’re so flush, hah), the OEM filters feel nice and dense, and I really like that they are one-button-per-function. Instead of using arrows and navigating around on a cheap LCD like my previous purifier, every button on these units serve a single clear function with no frills. Simplicity at its finest! ... show more

Review Image by Mark Kowaleski
We bought our Airmega 400 to handle some basic dust and allergy concerns in the house, as well as another layer of virus and bacteria infections protection. We are a family of 3 and no pets. We do have a central Honeywell F300 electrostatic system (rated at HEPA 13) (including UV light treatment), but we have found that it only works best when the central blower is running full blast (it is loud), so that is not working out for us. We bought one Airmega to try it out first, but I will probably add one more unit. We are in a newer 2100 SF ranch house with 100% hardwood floors and the Airmega is located in an open area (kitchen, dining, family room, sun room) that is 800 SF with high ceilings. This unit is just fabulous for that area! It has reduced dust by 90%. We vacuumed the pre-filter just once in two weeks and it definitely collected dust. When our fireplace is on, it actually distributes the heat throughout this area quite well, which is just incredible comfort. It has helped balance out the temperatures throughout the house. We move it at night to our bedroom suite (about 400 SF) and it has nearly eliminated dust under the bed. My sinus allergies are improved by 90% for sure - basically no congestion and I definitely sleep better due to no congestion at night. The machine, on low, is basically silent at night. I have an opinion that the “auto” mode feature is useless for air purification. Air needs to move to be filtered. The indicator is on blue 95% of the time (so I guess the air in our house is overall clean), which means that the unit would rarely run at all when on auto mode! What is the point of that? Why buy an air purifier only to have it on idle most of the time? It changes to purple when cooking or when the central heat kicks on (maybe some dust inducts). It also immediately detects when a candle is burning 10 feet away. It takes the Airmega about 5 minutes to go back to blue. When there is a lot of activity we sometimes get the yellow/red indicators going, and it clears things up very fast. We basically leave it on medium (which is quiet enough to allow normal conversation and watch TV). It has completely eliminated any visible dust particles in the air and almost all dust on surfaces like lamps and tables. Amazing, but you must have the machine running in order to accomplish that level of difference in visible air quality. Another side note: We have a commercial Santa-Fe Classic dehumidifier with a large 2” HEPA 13 filter in my fully finished 2100 SF basement . We run it year round on fan mode (it is 275 CFM) and the air in the basement is quite clear, especially in the humid months when the unit runs (I switch it to fan mode to get air flowing through it for purification). It was my experience with the Santa-Fe that compelled me to try the Airmega on the main level of the house. Air purifiers (and dehumidifiers) work, no doubt about it. You should know this: After just two weeks of ownership, the “medium” fan speed control stopped working! Amazon exchanged it for us no questions asked, but it sure does leave a very bad taste in my mouth considering the costs and simplicity of the machine. That said, the machine seems well made and appears to be high quality. At the end of the day, it is a plastic box with a fan and basic (thin) carbon and HEPA 13 filters. There is very little carbon in the filter, but we do notice it gets rid of cooking smells. It was packaged nicely (almost like Apple iPhone packaging), and it has a somewhat upscale and modern look. I may add one more dedicated Airmega unit to our bedroom on the other side of the house. Overall, very happy with the machine, but our initial experience is tainted due to the early failure of the speed control (the early failure is reason for 4-stars). ... show more

    • Quiet and effective
Style: 400 White
This is a fabulous purifier. It's so quiet, I wasn't sure it was on. But then I cooked something in the kitchen and it cranked up. It's really helped by allergies. It's not very heavy. I have to remember to turn it off when I light incense.

    • 5 yrs strong!!
Style: 400 White
I’m going on my 5th year using this device daily, it has rarely ever been turned off. I run it on the setting below the highest, always. I will say it isn’t quiet but it isn’t loud. It creates a nice white noise that is adaptable. I have replaced the filters in it every 9-12 months due to a dust issue living near a lot of farm land, plus I have all hardwood floors, no carpet. I have a small dog in the home who often has company and Im a smoker. Over all I feel like the air is fresh and it helps immensely with dust and dog hair! I never smell my dog or cigarettes in the home. When I come in after work and the house has been closed up all day, I can smell my plugins right outside the front door which is a great thing. I clean the pre-filters weekly and they normally have a good coating of dust and dander that I spray away down the sink. In the summer I sometimes find mosquitoes on the pre-filter! I hit the main filters with the Dyson about once a month as the fine dust does collect and prevent air flow. I have to admit that the original filters did a better job and lasted longer than the off-brand ones that I purchase for about $25 per set but the savings outweigh the loss of quality by far as they are quite comparable with fit and filtration. The sensor is very sensitive to the environmental changes and air flow will increase with change. I love that the front and back are also detachable by sliding upwards and can also be easily removed to be cleaned like the 2 magnetic sides that cover the filters. It has a night mode and a timer feature although I rarely use either. My home is a 1300 sq ft ranch style therefore the layout is somewhat boxy. The device is centrally placed however I believe the lay out of my home would be most benefited from an additional unit as the bedrooms still collect quite a bit of dust but are somewhat partitioned except the doorways. I will definitely purchase another Conway product when my budget allows as I’m very pleased with the reliability and ease of the airmega 400 however it was considered an investment at its price point. ... show more

I've had this air purifier for 5 years now and it still works great with minimal care and maintenance. It tells you exactly when and which filter needs replacement and the light is a countdown to when you need to as well. I love this air purifier. Great for people with dogs and cats. I bought this item for $365 +tax in 2021 just an FYI as I do see this being listed at almost $700 which is absolutely insane for a model was already a year old when I originally bought it. ... show more
