The great Korean company Coway produces some excellent air purifiers. For example, the Coway AP-1512HH and airmega 300 are great additions to their collection. So, cheers for choosing Coway!
However, I should clarify one thing and that is, you will get two variations of this Coway airmega 400 in the market. In terms of features, these two variations (400 and 400s) are identical except the 400s includes a WiFi smart control.
You can use this airmega 400s via a mobile app. And that is only the single difference between airmege 400 and 400s.
In the rest of the Coway airmege 400 review, we will discuss some important factors. The air purifier’s quality depends on these factors below.
- Design and size
- Filtration
- Filter replacement
- Fans and Functions
- Room coverage
- Noise level
- Power usage
- Warranty
Now, it’s time to know how the airmega 400 behaves in an uncontrolled environment.
Construction design
Coway’s latest flagship – the AIRMEGA 400 (AP-2015F) is a very premium looking air purifier in the market. At first glance, you may think it is a large speaker because of its design concept.
Furthermore, the airmega 400 is square-shaped and both the front and the backside of the device are almost similar with the perforated air grill which takes air from both sides.
Besides, there is a typical outlet vent on top of the device which takes out the fresh air. This design concept of the device can deliver the maximum efficiency even if you put it anywhere in your room.
Moreover, it comes with two color variations white and graphite/silver. And its sleek and clean design gives it an incredible appearance wherever it is placed.
Also, the unit stands at 22.9-inches height and 14.8 inches both depth and width. So, it takes up a little bit of space in your room but does not dominate the space.
Along with, the weight of this airmega 400 is 24.7 lbs which looks a little bit heavy and is about double the weight of Coway AP-1512HH. But it easily matches the weight of the Honeywell HPA300 air purifier. However, the weight of the airmega 400 is still a lot better than the Blueair Classic 605 which is 35 lbs.
As the air purifier is a little bit weighty, so it can be a little bit difficult for you in case of lugging it one place to another. However, it does have handles if you do decide to move this. But, yet be a little bit careful about carrying the device.
Filter types
The most important feature of an air purifier is filtration. To be more efficient in destroying any type of pollutants an air purifier must have a better filtration system. In this case, the coway airmega 400 is offering one of the best filtration systems that we are going to talk below.
Pre-filter: Coway Airmega 400 comes with a 3 multi stage physical air filters. The first stage has a permanent and washable filter. This filter helps to block larger objects of pollutants (PM10) such as pet fur, hair, lines, and dust. It also protects the primary filter from getting clogged.
Max2 filter: After the permanent pre-filter, you will get a combination of both an activated carbon filter and a HEPA filter, which they called max2 filter. This filter can trap 99.97% of tiny particles such as dust, mold spores, smoke particles, and others as small as 0.3 microns. It also absorbs more than 99 percent of household odors and VOCs such as NH3 and CH3CHO.
The airmega 400 has no ionizer feature, UVC light, or other electronic air filters. That’s why it is a 100% ozone free air purifier.
Filter replacement: Coway airmega 400 also has a filter replacement indicator that helps you to instantly know when to replace the filter. Max2 filter only can last almost a year.
Fans and Functions
You will have to operate The Coway Airmega 400 from its manual control interface. Because, It does not come with a remote control or an App. But, if you are concerned about this then you can go for similar airmega 400s which was mentioned earlier as it comes with wifi smart control.
Fan modes: Coway airmega 400 no longer has as many buttons as the previous Coway air purifiers. You will only have one on/off touch button and two air filter indicators on the unit.
However, the airmega 400 comes with five fan speeds that are smart, sleep, low, medium and high. If you’d prefer a different mode then just run your finger along the touch sensor to choose the mode you want.
Eco-mode: The coway airmega 400 is equipped with another interesting feature which is Eco mode.
When the air purifier is in Eco mode, the fan automatically turns off when the air quality sensor detects low pollution levels of the air for 10 minutes or more.
Once air quality drops, it automatically turns back on again until the sensor indicates good air quality again. The advantage of this is to give you a much more energy-efficient air purifier.
Instant air quality indicator: The air quality indicator is another bright side of this Coway airmega 400. You can instantly know how much clean or polluted your indoor environment is by just looking at the device. Displayed as a color-coded ring.
| Blue | Good |
| Purple | Moderate |
| Pink | Unhealthy |
| Red | Very unhealthy |
Timer or Auto shut off: If you do decide to run the device for a limited amount of time then select auto shut off in 1, 2, 4, and 8-hours. The essence of this great feature is helpful when you get to sleep and don’t need the air purifier to run the whole night.
Pre-wash button: We also appreciate the pre-wash button that will light up to alert you on the need to clean the pre-filters at 6 stages; 100%, 80%, 60%, 49%, 20%, and 0%.
Room coverage, ACH and CADR
If you are looking for an air purifier for large spaces, such as spacious living rooms, combination living, dining, and kitchen open- floor space, garage, gym, and basements, then the airmega 400 can be the right choice for you. Because, this device has an impressive room coverage which can easily handle up to 1560 square feet area.
ACH: The airmega 400 offers only 2x ACH. So, it can purify its coverage area two times per hour which isn’t as impressive as its room coverage or other spaces.
This ACH is on par with Rabbit Air MinusA2 Rabbit, but not as good as how Honeywell HPA600B can do. As a high range air purifier, its ACH should be 4x or more. However, if you want to achieve 4x ACH then use the device in a room that’s half the size that’s recommended.
CADR: The CADR rating of AIRMEGA 400 is not mentioned in the manual. That means the CADR rating of airmega 400 is not verified by the Association of Home Appliance Manufacturers (AHAM) which is an independent testing organization for air cleaning devices. Actually, some manufacturers choose to ignore the test for their product. So, it is not a big issue for an air purifier and it does not affect its performance at all.
Low noise profile:
The noise produced from this airmega 400 is surprisingly low. At lowest, it is just 22dB, below the whisper level. If you run the device at the highest setting, the noise level is also low, only 52dB. So, you can run the unit at the highest setting when all you want to do is sleep and forget about the little devils!
Power Usage
With only 64 watts, the airmega 400 is one of the best energy-saving air purifiers in the market. Thanks to the reliable Eco Mode which increases the efficiency of the air purifier in saving energy cost. If you run this energy star certified air purifier regularly you need to pay approximately $24 per year. That means the airmega 400 has a double cleaning power with only the same energy cost as the Winix 5500-2.
Warranty
The Coway airmega 400 offers a long 5-year warranty on their motor and electric parts. And that is just too good for the users as it is double or triple the amount compared to other brands.
