This post is the latest in our series of Coway Air Purifiers. We have discussed in great detail about Coway air purifiers in various posts. Time now to analyze the largest of all the models we have covered so far. This Coway Airmega 400 review highlights areas where it is good at. Not just it, we take a look at its smarter version, the Coway Airmega 400S too. Earlier we reviewed Airmega 300. The AirMega 300 is just a little smaller in size. From a distance both brothers are indiscernible.
Choosing an air purifier can often turn into a confusing and tedious affair. There are so many brands and a multitude of models out there. This is where unbiased reviews can help. But, how to differentiate true reviews from fake and paid ones? Its simple, search for reviews from verified consumers and multiple sources. If you have patronized a blog then watch out if it has only positive things to say for every product. Match what the blog says with what online reviews on Amazon or eBay say. This should give you a fair idea of what to expect.
COWAY AIRMEGA 400 REVIEW – Why Its A Cut Above
The first and foremost thing all of us are interested in knowing is whether an air purifier delivers on its promise. Promise of performance, efficiency and good customer support. My answer for Coway Airmega 400S is a big Yes but a squeaky No both. The Yes outnumber the No by a good margin. If you have a big living room touching 1500 sq.ft then go for it.
- The fans generate very good air circulation. The high coverage area which is marketed is not a sham.
- Excellent air purification is achieved by the double set of the MAX2 filters. TRUE HEPA and activated carbon filters constitute a composite filter called the MAX2 filter.
- Some entry models from Coway lack a couple basic convenience features. Not so with the Coway Airmega 400 and 400S.
- The Airmega 400S Smart air purifier is WiFi enabled like its smaller brother 300S. The Coway 300 and 400 series being the top of the line air purifiers, are a robust air cleaning package.
- We all come across negative reviews for a product. But, do not like even the idea of experiencing it ourselves. You can see how users have reviewed Coway air purifiers. Anyways, for starters Coway air purifiers are world renowned with their origin in Korea. Which one you may ask – North or South? Ofcourse South Korea, where Samsung originated. That little psycho dictator of the north only produces bombs!
- Not everyone can think of comfortably buying it. The filters last considerably long. Whenever they need replacement, a considerable amount needs to be shelled out. Its a little impractical to spend this much on an air purifier.
- The size is quite imposing so you need to consider this factor as well.
INSIGHT – ITS AIR CLEANING
Just to let you know distinctively that there is no Ionizer or UV light provision. Some US states have stringent guidelines for what can be sold on marketplaces and what not. Ionizers as you may already know are always looked with suspicion as a source of ozone. Ozone can be harmful in the long-run.
AIR CHANGES PER HOUR (ACH)
ACH is an important parameter which indicates the performance of an air purifier. The more the ACH the better it is. This reflects how many times the complete volume of the room passes through the filters in an hour. This can be more that the rated value if a larger air purifier is used in a small space. For the Coway Airmega 400, ACH stands at 2 air changes per hour. If you place your Airmega in a 1,560 ft2 room then it will clean all of the room’s air atleast twice hourly.
The ACH can go up to 4 if used in a room sized 780 sq.ft. The height of the ceiling should be 8 feet as a standard. For patients of asthma and allergies specialist recommend an ACH of 4 or above. I hope you are liking this Coway airmega 400 review till now?
EFFECT ON DUST, POLLEN AND SMOKE
I must say that if after spending this much money an air purifier fails to remove all of these, then its trash. As expected the AirMega 400 counters these pollutants like a boss! You can look at the CADR values in the table below. The low fan speeds are very quiet but the highest one records around 56 dB. The particle sensors modulate the fan speed according to how much pollution is around. For your satisfaction you can experiment yourself to see if indeed what we say is true. Let me tell you what you can do.
Put the air purifier in SMART mode which is the default mode by the way. Bring some cigarette smoke or incense stick near to the air purifier. Let the pollution reach the sensors and see how the device reacts. SMART mode intelligently increases the fan speed to arrest the pollutants. The LED lights in the front change their colors to reflect all these air quality changes.
COMPARE COWAY AIRMEGA 400 vs 400S
There are a couple of differences between the AirMega 400 vs 400S. Same two differences exist for AirMega 300 vs 300S. One difference is that the ‘S’ version has an extra 2 hour timer setting. So, you have 1/2/4 and 8 hour timers in 300S/400S. Only 1/4 and 8 hour settings are available in Airmega 300/400.
THE IoCARE APP
The 400S and 300S both have a WiFi module which 400 and 300 lack. The IoCare APP enables controlling the air purifier through your mobile or tablet. The APP shows you outdoor and indoor air quality comparison, temperature, humidity and much more. Not just this, Alexa voice control is a possibility now. You can ask the AirMega to switch fan speeds, set timers or about the air quality levels.
The Airmega 400S is the Smart version of Airmega 400. Don’t confuse it with the SMART mode which is present in both. By ‘smart’ what we mean is intelligent. There are three subtle differences between the two models. First would be the price difference which is close to a 100 bucks. Second is the ability of the air purifier to be connected to WiFi. The trend of connected devices controllable by voice or mobile Apps is getting viral. You can instruct the air purifier using Alexa and it will do some predefined tasks for you.
Third difference is in the Timer functionality. The Smart models have an advanced timer that can be scheduled. Here you can choose the time interval in which the air purifier should turn ON and OFF. Not just this you can choose the day of the week to schedule the timer. Isn’t it a great thing to have! Setting timers for preset number of hours is a basic thing. Coway Airmega has taken it one step ahead with a Scheduler. You can now define in advance the time when the timer would start. Say, you can set the timer for 8 hours, 2 hours from current time.
The mobile APP is very informative. So much so that some people get bogged down by information. APP, WiFi connectivity, Scheduler are good features to have. But, I doubt you’ll want to spend extra for it. With all due consideration, the Airmega 400 is still our preference.
CONCLUSION – COWAY AIRMEGA 400 REVIEW
If your pocket allows you then there’s no issues in owning a Coway Airmega 400. Still deeper pockets and Airmega 400S can be yours too. I have tried to explain in good detail the subtle differences in features of the two. You can decide if the extra things that Airmega 400S brings forth are of any worth to you. My personal choice if i were to make a choice would be the Airmega 400. I see no point in shelling out extra money for things which I can do manually. Take the case of outdoor air quality dashboard in Airmega 400S. I can see that info on websites. Moreover, the App still does not show real-time PM2.5 reading which if present I could have been moved to buy it. This Cost i think i can afford.
