ABSOLUTELY REFRESHING

I was having issues with my downstairs neighbor cooking and the smell going through my floor vent. I decided enough was enough and looked into heppa air filters. I saw Coway recommended a few times and thought the design for the Airmax 240 looked nice and would fit neatly in my office. I was correct. It fit great. What I wasn't expecting was how easy to setup and maintain the unit would be. It has two filters, the Heppa filter which I clean once a month and replace annually and a front mesh filter that's simple to pop out (there is a convenient plastic tab) which I clean quickly each week using my dust buster. I literally change it along with my PC dust filters and it takes like 3 minutes. The front grill pattern is nice and the unit is very quiet unless you put it on max setting. I keep it on auto which automatically adjusts as needed and it only gets really loud if I fart into the sensor which makes the LED turn a comical red. Great machine and it can clean a large room and a lot of cooking and fart smells for those wondering. 👍

Works great, and looks nice too

Works great, and looks nice too. It's quiet, especially on low, but even on higher fan speeds, not to distracting

Great investment- especially with wildfire season

I like how quiet this runs. Even at full fan speed it’s like white noise. The air quality in my apartment is noticeably better after 2 days of running it. I run it on smart mode almost always and it meets my needs. It has a vintage look to it and blends well with decor. Love it!

Amazing filter

Bought this one as a second filter because the first one (identical model) worked so well. Extremely quiet, works very well (judging by both elimination of wildfire smoke and sickness not getting passed between people in the same room over a long period of time).

I loved it so much I bought another!

I bought an Airmega 400 and 240 this past winter and love them. So I had buy another Airmega 240 for our master bedroom. It works so well that we sleep even better now with cleaner air. Night or sleep mode is so quiet but still cleans the air and automatically turns on from Smart mode. I like that you can also manually switch to sleep mode or turn off all the lights. This model is great for any room in the house.

Clever Design

I've owned several air purifiers over the years and this Coway Airmega is the best one. It's sleep feature is so quiet it doesn't disturb my sleeping. The design allows you to place it against a wall and has a screen you can pull out and clean. One of my co-workers recommend as she has had hers for several years and still loves it. My allergies are terrible and this has made a huge difference for me at home.

A great investment for our family of 4 kids and 2 adults who struggle with allergies and our 2 fur babies

Not too bulky or ugly, with 2 furry pets and 4 kids and 2 adult who all struggle with allergies, this product works so well. Ive definitely been able to tell a difference in the air quality and i love that you can feel movement in the air even sitting across the room. We were hesitant on spending this much for a purifier but its been well worth the money! The filter is easy to clean too which is a plus.

Efficiently captures and eliminates polluation

[This review was collected as part of a promotion.] This Airmega 240 HEPA filtration system is remarkable. It efficiently captures and eliminates airborne pollutants, allergens, and odors, leaving the air noticeably cleaner and fresher. I have noticed a significant reduction in dust particles and pet dander, which is a game-changer for my allergies. The air quality indicator is a great feature that keeps me informed about the air conditions in real-time. It accurately displays the current air quality level using a color-coded system, allowing me to adjust the settings accordingly. The auto mode is incredibly convenient as it automatically adjusts the fan speed based on the detected air quality, ensuring optimal purification without any effort on my part. The timer function is a fantastic addition, allowing me to set the purifier to run for a specific duration. It's especially useful when I want it to operate during certain times of the day or night. Additionally, the filter replacement indicator takes away the guesswork, notifying me when it's time to replace the filters, ensuring that the unit maintains its peak performance. The Airmega 240 is designed for spaces up to 403 sq. ft., and it effectively covers the entirety of my living area. The sleek white design effortlessly blends into my decor, and the unit operates quietly, not disturbing me during my daily activities or sleep. Overall, I highly recommend the Airmega 240 True HEPA Air Purifier to anyone in need of a powerful and reliable air purification system. Its exceptional performance, convenient features, and robust filtration capabilities make it a standout product in the market.

Quiet and does the job well

Very quiet unit. I don't even notice it is running on low settings. In Smart setting, it adjusts its fan speed based on what the sensor reads in the air. The only thing I wish it has wheels to move around a little easier without scratching the floors.

Great product

[This review was collected as part of a promotion.] My wife and I purchased a home in March. It was so stuffy feeling and the air quality just sucked. It was carpeted throughout. We pulled the carpet and started using this purifier and we noticed a big difference. We have it placed in between the kitchen and living room. It has removed the odors the previous owners left behind lol. It’s very easy to setup. It’s really quite I forget it’s on unless I see the light indicating it’s still on. I leave it on smart setting and just let it be. Our kitchen and living room is grayish it goes perfect with the decor.

Awesome Addition to the House

[This review was collected as part of a promotion.] I've actually never owned an Air Purifier before and recently moved into a smaller apartment, with pets, in the midst of allergy season. This machine is wonderful and was so easy to set up right out of the box. It's a little large, but being neutral colored is great for my space. It's not too loud, which was something I was worried about, and it's super simple to change the different modes. I like that I don't need to use a remote as I tend to just lose them/ end up using the buttons on whatever device I have anyways. I feel like the air in my apartment is so much better and cleaner. I haven't yet had to change out the filter but that also seems to be very easy! All in all, really happy with this and glad I finally thought about getting an air purifier.

Helped make our musty basement smell fresh

[This review was collected as part of a promotion.] We are currently living with family in their basement room and when we moved in it was quite musty. We got Airmega 240 to help clean the air and it has done a great job reducing the musty odors and making the toom more livable.

So good

[This review was collected as part of a promotion.] I needed something to keep my house, feeling clean and keep dust off of my electronics. This product was absolutely amazing and did everything it was supposed to and it looks great. I will always have one of these in my office as I feel like it helps me with my work and helps my room feel great.

Perfect for my son with allergies!

[This review was collected as part of a promotion.] I'll admit when I got this I was a little skeptical about everything it claimed to filter out. But after only a few hours I already noticed a difference in the air quality in the room. My son has dust and pollen allergies and his sinuses were really bothering him. After a few nights of having the purifier in the house he doesn't seem to be having issues inside anymore. It was super simple to set up and get started and there's a light indicator to tell you when it needs a new filter. It's about as loud as a fan so not that bad. There's definitely a draft around it though where it shoots out the clean air and it can be a little chilly at times if you're right next to it. But I can definitely tell a difference in the quality of air in my house and I love it!

Nice Air purifier

[This review was collected as part of a promotion.] GIVE IT TIME; I have to stress this due to the smell that the new filter emits. I plugged mine in and had it running in seconds. Operation is very easy and smooth. I love the smart option that selects the setting for you based on air quality. Once the smell went away from the new filter, it didn't take long and the air in the room seemed to be a much better quality. I like the ease of access and use of the pre-filter in the front. I clean it once a week with a vacuum. Great purifier and blows cold air out too.

Powerful machine

[This review was collected as part of a promotion.] This is the 4th in my house. My MIL used to smoke so I became a bit neurotic about the indoor air quality in our building (she lives downstairs) anyway, this air purifier is huge. I wasn’t expecting it to be this size but I am so glad it is, it has replaced the use of two purifiers I used in one area. The color and design make it look like art. It’s very nice.
