Coway Sleek Pro air purifier has taken the Indian air purifier market by storm since it showed up on online portals. Coway, a Korean brand boasts of being one of the world’s biggest air purifier sellers of all times. Its air purifiers are a rage, especially in the USA where the Coway Airmega 300S and Airmega 400S set the benchmark very high with their performance and unique designs. MI, a Chinese brand, has also had a very successful stint in India with its affordable yet feature packed MI Air Purifiers. MI first introduced the MI Air Purifier, followed by MI Air Purifier 2, and then its smarter version the MI Air Purifier 2S. Now the latest in the series, the MI Air Purifier 3 has wowed the users.
In this Coway vs MI air purifier post, you’ll know some subtle differences between these path breaking air purifiers.

COMPARE COWAY vs MI AIR PURIFIER
To compare these two air purifiers, I would be taking up one specification at a time. For your convenience I’d also be listing out a summary table for a quick glance.
PRICE ON AMAZON
Price-wise there cannot be any comparison. Coway Sleek Pro has its price fluctuating all round the year between 13,000 – 17,000 INR. MI air purifier 3 on the contrary has a fixed price of just a tad below 10 Grands. It is arguably a very cost efficient air purifier. If we see its features then you’d find the Coway Sleek Pro lacking.
COUNTRY OF ORIGIN
Coway is a well-known Korean company. While MI is a Chinese brand. Considering the fact that China is India’s enemy No.1 ,I would shun its products at all costs. Still for the sake of comparison, I would remain unbiased throughout the post.
Coway Sleek Pro has comfortable press buttons which produce a short jingle when pressed. MI air purifier 3 has a touch screen as well as WiFi and APP connectivity. From security point of view, I would not download or install MI App if I were you.
REAL-TIME PM2.5 DIGITAL INDICATOR
This is one feature I always rue its absence in the Coway Sleek Pro air purifier. Not sure why the company is not considering to include this. I am sure in some upcoming models, Coway would seriously add this feature.
Coming to how the real-time pollution display works in the MI air purifier. I am mighty impressed with the accuracy and specifically the sensitivity of the particle sensor. I’ve tried a few times by lighting match sticks, and the particle count does go up quickly. Even by the closing and opening of doors, the sudden change in air pressure changes the PM2.5 in the otherwise sealed (nearly) room.
|Coway vs MI Dimensions (H*W*D)||666 x 335 x 205 mm||520 x 240 x 240 mm|
As you can see Coway is bigger then the MI Air purifier 3. In terms of weight too, Coway weighs 5.9 Kilos as against MI’s 4.8 Kgs. Overall, MI air purifier 3 is more portable and light. In terms of stability, both air purifiers are equally stable. Coway Sleek Pro may look like it may topple anytime, but its just an illusion.
You do not find any handle or niche to lift MI air purifier up. Its so light and compact that you can wrap your arms around it to lift it up. Coway has a niche at the top back to put your fingers in for lifting.

Even though the Coway Sleek Pro is bigger in size yet MI air purifier 3 scores better in this area. The MI Air purifier has a specially well-designed fan inspired from jet-engines. This creates a powerful air current in the room. Also, MI air purifier has a round filter which takes in impure air from three sides. Contrast this with Coway’s rectangular filters which pull the air from two crevices on the sides of the air purifier body.
Coway Sleek Pro – 355 sq.ft.
MI Air Purifier – 484 sq.ft.
CADR (Clean Air Delivery Rate)
On this parameter too, MI Air purifier steals the show. As I already mentioned above that the MI air purifier has an excellent air circulation thanks to its powerful fan. This makes it capable of cleaning more air per hour. For your reference, MI has a CADR of 380 m³/h while Coway AP-1009 has a CADR of 303 m³/h.
Whatever air the Coway Sleek Pro cleans, it does so excellently. Users of Coway notice a marked improvement in not just air quality but also the foul smells are gone. The air smells different, which people living in cities seldom experience. Its the smell of freshness and purity. In terms of filter quality, Coway wins hands down. It is not to suggest that the filter used in MI air purifier is any inferior. It is a H13 grade filter and is of international standards. But, it is the overall performance and the impact of air quality that Coway air purifier produces.
I am not impressed with MI air purifier’s ability to remove odors. Be it kitchen odors while the food is being prepared or the smell of crop stubble burning in nearby states. I have never been satisfied with MI air purifier in this aspect. Overall, from the point of view of air cleansing, it is good. Bringing down pollution levels quickly is one of its good things worth mentioning.
Coway Sleek Pro has a pair of filters that are clubbed together when put in the air purifier assembly. These are the anti-flu HEPA filter and the carbon filters. Coway’s HEPA filter is coated with a special compound extracted from some native plants. This green coating renders viruses ineffective by breaking their cell walls. In times of this virus pandemic, it is a very good feature. Coway’s replacement filters cost much more than MI. This Coway vs MI air purifier war is getting heated up right?
MI air purifier 3 on the other hand has a single compound filter in the shape of a cylinder. The outermost layer is the pre-filter made of nylon. The middle layer is that of a True HEPA filter. An activated carbon layer forms the innermost layer of the composite filter.
NOISE – COWAY vs MI
Coway Sleek Pro is definitely the quietest air purifier around. At lowest fan speed, Coway registers just 22 dB on the decibel meter. Coway is super quiet when running at full throttle. At max fan speed, it makes 45 dB noise, very silent operation is Coway Sleek Pro’s USP.
MI air purifier 3 gets noisy at highest fan speed. My mother can’t even sleep with the air purifier ON, now you’d slowly understand why Coway is so popular. What good is an air purifier’s coverage if some light sleepers can’t sleep? For this, we put this Turbo mode on our MI air purifier before going to sleep. When its time to go to bed, the Sleep Mode is the best deal.
Coway Sleek Pro air purifier offers more control over the fan speed. It allows you to choose from 4 speed levels. Speed level 1, 2 , 3 and a Turbo mode. On the other hand, speed setting 3 is the maximum fan speed setting for the MI air purifier.
What is the purpose of the Sleep mode in air purifiers? It is there so that the air purifier lights and fan noise does not interrupt your night’s sleep. The air purifier operates at its lowest fan speed so as to make the least noise. Also, its LED lights are dimmed or completely shut-off in this mode. An air purifier running in Sleep Mode is akin to a compromised efficiency as the fan at a very low speed cannot remove the pollutants well.
Coming to the applicability of Sleep mode in the Coway Sleek Pro. This air purifier is already so silent that its operation does not hinder the family’s sleep. For the air quality indicator lights there is a MOOD lamp to turn them off. Problem solved! You need to not that you can run your Coway Sleek Pro at max speed in Turbo mode while sleeping comfortably. Yet another reason to go for this masterpiece!
Coway Sleek Pro air purifier does not have a Timer.
MI air purifier 3 does not have a timer on the air purifier body. Instead, you can make the air purifier to start or stop at a set schedule via its APP.
WiFi And APP Connectivity
MI air purifier is a smart air purifier replete with WiFi and mobile application functionality. It can be very well controlled through the APP once it is paired with the air purifier. The APP shows statistics of real-time pollution, and can do all that the touch buttons on the air purifier can do. You can voice control it with ALEXA as well.
Coway air purifier lacks all these features. But, what is the use of all these features when the MI application leaves you vulnerable at the hands of China’s sinister motives of stealing your data ? It is for a reason that Chinese APPs are being flagged for data theft and privacy concerns worldwide.
The Coway Air purifier consumes more power than your MI air purifier. Its all in the excellent fan design of the latter. The difference however is not very tangible. One would not even notice any difference in their monthly bills. Just for the sake of brevity, Coway consumes 49 W and MI air purifier eats 38 W.
Coway offers a 5 years warranty on the fan motor and 1 year warranty on electrical parts. Any physical damage to the air purifier body is not covered in warranty. MI offers only a 1 year peace of mind. There is no comparison in the level of peace of mind you can enjoy if you choose Coway over MI air purifier. The reason for this is simple. Coway has one of the best after sales support. Their customer care representatives are very professional and helpful.
MI is nowhere to be seen should you face any issues with your air purifier. Just like any other Chinese product, if it works well its your good luck, if it doesn’t still its your own luck.
VERDICT – Compare Coway Sleek Pro And MI Air Purifier
Coway Sleek Pro air purifier is a simple air purifier devoted to excellent air cleaning. Coway has this knack of keeping things as simple as possible. At the end of the day, an air purifier must produce perfectly clean air. It hardly matters if it allows you to control it with an APP or voice assistant or not. MI air purifier, although very feature studded for its price, lags behind in the noise and air cleaning part. Also, MI being a Chinese company is bound to have lost the favor of patriotic Indians.
Of the rare users of Coway who’ve faced some issues with their air purifiers, they have a common thing to say. They all agree that Coway’s response to their issues was very well received and helping. What more can a customer ask for? A product par excellence and that too from the World leader in air purifiers, that’s Coway for you.
Hope you found this Coway vs MI air purifier comparison informative!
