About Coway Air Purifiers: Popular Models Compared
To start with Coway air purifier models, 2-3 years back, there was only one model, Coway AirMega 150. It became not only India’s but one of the world’s most-rated air purifiers. It’s still the best-selling air purifier to buy in India online 2024.
About 1 year after another model, Coway AirMega 200 (AP-1018F) launched in the market. With slight improvements, it comes with a price of about 7,000 more than the Coway Airmega 150. I didn’t like it much. So, as expected it didn’t become that popular. It’s also not available on Amazon this time.
Now, in place of it, there is the newer model Coway AirMega 250 (AP 1720B) for extra large areas (up to 930 sq ft). It claims to clean the air in this space within just 30 minutes. It is priced at around 25,000.
There is another model, Coway AirMega Storm (AP-1220B), with some advanced modes & megajet technology. It’s a good air purifier for big areas (coverage area 575 sq foot).
Now coming to the next & latest coway air purifier which is also my favorite in 2024, Coway Airmega Aim. Suitable for small-medium spaces, the special thing is it has oscillation angles.
To know more about these 4 models please continue reading the article.
1. Body & filter designs
All four models including Coway Air Mega 150 have a sleek minimalist design which makes them suitable for every nook and corner.
They have the thickest Green Anti-Virus HEPA filter (25 mm) with the longest life span of around 8500 hours. Because of the cartridge-type design, you can detach the whole filter tray with only a touch of a button and can carry it to a cleaning area.
You won’t need to separate filters because they are designed in a way you can vacuum them together without any hassle. It means that you don’t have to worry about getting your clothes dirty while cleaning.
2. Technology & modes used in coway air purifier models
According to different models, Coway has installed the latest & different technologies.
The common features:
- Optimized airflow design which ensures better reach and maximum airflow.
- The green anti-virus true HEPA filter is made up of Gingko and Sumac plants which have the unique property of a damaged protein present on the virus surface making it harmless to us.
- In the auto mode, the air purifier monitors the air quality. And when it senses any dip, it automatically switches between its different modes.
- In the night mode, it turns off all its lights so that you can enjoy full darkness for a good night’s sleep.
- All models have a child lock and a filter replacement and cleaning indicator too. There are real-time air quality indicators too.
Besides it, Coway Air mega storm priced at around 22,000, has some extra modes like eco (to save energy) & turbo mode (for quick cleaning in just 6 mins) and uses MegaJet technology to regulate the airflow in your premises.
Turbo mode is for those situations where air quality dips to severe levels or you want space to clean ASAP. Eco mode is the best mode if you live in the suburbs; it will keep your surroundings clean and prolong the filter’s life.
And coway Airmega 250 comes with smart mode(automatically adjusts fan speed) & rapid mode(extra fast air cleaning).
3. The filtration process & pollutants removed
Each coway air purifier model comes with 3 different filters to let you inhale pure air again up to 99%.
- Pre-Filter for PM10 particles:
- Activated carbon filter for deodorizing the air and removing VOCs and cigarette smoke and,
- A unique Anti-Virus Green HEPA filter made up of Gingko (Japanese leaves) and Sumac (Japanese tree). It is the thickest HEPA filter that traps 99.97% of PM 2.5 particles, bacteria, pollens, and 99.9 % of allergens, and Viruses.
Overall, with all technologies & filters, Coway claims to remove impurities up to 0.1 microns.
It’s a big claim indeed. If you look at other air purifiers like Sharp, Philips, and Qubo, they guarantee to remove impurities up to 0.3 microns. Only Dyson with HEPA 13 filter & its air multiplier technology claims to capture but with a minimum efficiency of 99.95%.
Things to consider:
The reason is they are designed to capture particles down to 0.3 microns with a minimum efficiency of 99.995%. While the filter is officially rated for 0.3 microns, it is also capable of capturing smaller particles, including those as small as 0.1 microns, although with slightly lower efficiency. For Dyson air purifiers using H13 filters, they are also effective at capturing particles down to 0.1 microns, but with a minimum efficiency of 99.95%. While the H13 filter is slightly less efficient than the H14 filter, it is still highly effective at capturing ultrafine particles. And, how much level of impurities your air purifier can capture, depends upon many factors like the technologies, modes, and cadr /polar test. In short, all are capable of giving you clean indoor air.
4. Coway air purifier cadr & coverage area (all models)
It is an important figure that all prospective buyers should keep in mind. CADR refers to the Clean Air Delivery Rate.
Starting with Coway Airmega 150, it has a CADR of 303 cubic m/hr. Sufficient enough for a coverage area of 355 sq. ft./ 33 sq. meters. You can see, it is ideal for small offices or medium-sized rooms to maintain the clean air in it with no hassle.
Another model apt for small-medium sized spaces, Coway Airmega Aim has a similar CADR: 303 cubic m/hr & coverage Area is 355 sq. ft. But I don’t think the CADR is right. It’s given on the higher side. You just remember that both the air purifiers work well and do their job.
Now coming to Coway Air Purifier models suitable for larger spaces, Coway Airmega Storm & Coway Airmega 250. Coway Airmega Storm (AP-1220B) has 309 cubic m/h around & a coverage area: of 575 sq ft.
Coway Airmega 250 supports a coverage area of up to 930 sq ft if the round of changing air is 2 and up to 1860 sq ft if the air change round is only 1. They have given these levels on their website. And cadr is up to 249 for smoke-like impurities.
It’s important to note here the CADR value indicates how fast an air purifier can clean all the pollutants and other unwanted particles to give you clean air.
The higher the Clean Air Delivery Rate, the higher the clean rate of the product!
It’s important to consider that CADR alone is not responsible, additional features like filtration technologies & modes play an equal role. Therefore, Coway has added rapid mode & smart modes. Coway air mega Storm also has mega jet technology.
Still, if you think that the CADR level is not sufficient in Air Mega 250 & storm, if the room has high levels of pollution or if you have specific concerns about certain pollutants, you should go for a purifier with a higher CADR or additional filtration capabilities.
For example: a Dyson air purifier with air multiplier technology.
5. Quality & pollution indicators
All coway air purifier models mentioned above including Coway Airmega 150 come fitted with pollution indicators which give you a real-time update on your room’s air quality.
Indicators are blue, green, yellow and red in decreasing order of air quality. It also has indicators for filter cleaning and replacement so you never have to breathe impure air.
6. Power consumption & noise level
An air purifier is an electronic device so it is obvious to worry about the power consumption and the noise of the motor. No one wants a hefty power bill or the whirring sound of a motor disturbing the peace of your home.
Thankfully, coway air purifier models have an energy-efficient yet silent motor. In coway Airmega 150, It needs a supply of 230V 50 Hz and power consumption is 38 Watts. Its noise level is also low with a range of 22-49 dB.
Only in turbo mode, you will hear the motor sound noticeably but then again, you will not run it in turbo mode always as it is for emergency purposes only.
In all models, these nos. are almost the same.
However, in Air Mega 250, the power consumption is 64 watts and noise level up to 59 dB. Do you remember it comes with smart & rapid mode? That’s the reason the nos are high. In normal mode, both power & noise will be low.
7. Sensors & other features
In today’s world, technology means nothing if it doesn’t offer convenience especially when it comes to home appliances. Coway Air purifier handling comes with minimum hassle.
Each model actively monitors the air quality and switches between modes to give you fresh clean air as well as prolong the life of filters without even disturbing you.
The only manual work you have to do is to change the filters and its tray can be opened with a single button touch.
So no more fiddling or figuring out how to open the filter panel and getting your hands or clothes dirty!
Just press the button, take the old filter out and install a new one. Easy as it gets.
8. COWAY Air Purifier Cleaning & Maintenance
All 4 models including Coway Air Mega 150 are equipped with a unique design and batch separation system where you can easily and safely clean the filters. Contactless cleaning extends the life of filters.
You can separately clean the pre-filter whenever you want without touching the HEPA & Carbon filter. For cleaning HEPA & Carbon filters, you just need to take the front panel out.
There is a pull tag on the HEPA filter to facilitate contactless cleaning and protect it from viruses and other allergens.
By using this tag, you can vacuum clean the carbon filter without separating it from the HEPA filter.
9. Limitations
No product is 100% perfect and Coway is no exception. They might have some limitations, one size can’t fit all.
- Average control panel in cheaper models
- The Coway app isn’t very impressive
- The small size of the filter replacement LED
- Coway Air mega 150 Buttons are a bit slow. The power button and the quality indicator are not well placed and hidden in the device design.
- Also, they are normally quiet while in operation but in turbo mode, they can make a high amount of sound. But, let me tell you, every brand’s air purifiers make noise in turbo mode.
10. Coway Air Purifier price & warranty: all models 2024
Airmega 150 costs under 15,000 this time for all its features and superior quality.
Coway Air Mega Aim comes with around 11,000, a smaller coverage area but with oscillation angles which is a very awesome feature. It’s 2 in 1 machine, a fan cum air purifier.
Model AP-1220B is priced at 22,000 & model 250 is at 25,000 this time.
The company website mentions a 1-year product warranty and a 5-year warranty on the motor on all models. It’s really good and no other air purifier company offers this much longer warranty period.
Coway also offers an extra 2-year warranty on the motor if you register your device with Coway.
At this price point with all these amenities, we do believe that all Coway air purifier models are unique in their own way.
Buying one of them is a solid deal and that’s why Coway is the no. 1 selling air purifier in India.
Comparison with Other Popular Air Purifiers
While we are at it, let’s take a look at other air purifiers offering the same technologies and benefits and compare them.

- The point where Coway Air Mega wins is that it can remove 0.1-micron impurities while Mi air purifiers 3 & 4 claim to remove only 0.3 microns.
- Honestly, with its 1 filter, it does a decent job but when we compare it with Coway AirMega 150, both work on a triple-layer filtration process.

- And cleaning or replacing the filters is a hassle in Mi 3 & 4 because of its design.

3. Coway Air Mega 150 vs Philips AC1215/20 Air purifier
- Philips AC1215/20 is a good one with its 4-stage filtration and a good CADR. It also has a night mode and air quality indicator like Coway but it just lacks the superior purification quality of Coway.
- There have been reports of some faulty products which don’t show the correct stats/data or don’t do their job correctly.
- But if we talk about Coway, there have been very few incidents like that.
- On top of that, Coway’s customer service is far better than Philips’s. They are more helpful, professional and readily available pan India.
- Philips Air purifier costs under 10,000.
4. Coway Air Mega 150 vs Honeywell Air Touch A5
- Honeywell Air Touch 5 air purifier is good if we are considering a light air purifier as its filter life is only 3000 hours and has a CADR of only 250m3/h. Whereas on Coway the filter life is approximately 8000 hours and it has a much higher Clean Air Delivery Rate.
- The filtration capacity in Honeywell is not made to endure the highly polluted cities of India.
- You will have to change or clean its filters every month or so to optimize its airflow. And it will be a headache removing those filters unlike in Coway where you can remove them with a single button touch.
- Honeywell air purifier costs Rs. 8,000.
5. Coway Air Mega 150 vs Sharp Air Purifier
- The Sharp Air Purifier is a basic one with no fancy frills or anything like that but it does its job good. It is the most underrated air purifier priced at around 10,000.
- It has a coverage area of 320 sq. ft. and, it will clean the air in 15 minutes or so and you can breathe fresh and clean air.
- But Sharp is meant only for small spaces.
- When you think of Coway, imagine it to be a step up on this purifier with its higher CADR, more coverage area, more efficient HEPA filter, smart indicators and ease of usage.
- Coway Professional Air Purifier is considered to be the best-selling one in the world. And this is because they do their job efficiently.
- And if there is a problem, then their service personnel do their job efficiently.
