The original Coway Mighty is a legend… It’s been on the market for over 10 years, and in that time, it has become one of the most recommended air purifiers online.
But the reign of the Mighty has potentially come to an end with the release of the Coway Airmega Mighty2 AP-1512N in March 2026.
But is this new Mighty2 better than the original Mighty? And how does it compare to popular mid-sized air purifiers like the Levoit Vital 200S and the Winix 5510?
I bought one with my own money to test its air cleaning performance, sound generation, energy efficiency, yearly running costs, and day-to-day user experience.

The pros and cons of the Coway Airmega Mighty2 AP-1512N
A summary of our top-level findings after testing this air purifier, following our methodology.
“The Coway Mighty2 looks like a million bucks and, in our tests, it outperformed the original Mighty AP-1512hh, the popular Levoit Vital 200S AND both the Winix 5510 and the 5520. Outstanding and unexpected.
When you compare it to PC fan-powered units, it still loses on raw power but for a traditional mid-sized air purifier, the Mighty2 is one of the best options out there — especially considering how quiet it is.”

Filtration technology
An all-in-one filter that combines HEPA-grade particle filtration with pelleted activated carbon.
The filter is larger than the ones in the old Mighty and the 200M, and it comes with pelleted carbon, which offers better odor removal.
The downside of bonded filters like this one is that you will need to replace the whole thing when the carbon filter runs out, which usually happens before the main particle filter needs replacing. But they help improve performance.
You can easily slide the pre-filter out to vacuum it or wash it without opening the front cover, unlike with other models.
Not only is this feature cool, but it also significantly minimizes the amount of dust and fluff that fly into the air every time you open the front cover when the time comes to clean the pre-filter.
The short answer: yes, but only when running in sleep mode.
This might seem odd, but it’s actually just science – the higher the speed of the air flowing through the filters, the higher the penetration of particles and the lower the CADR. You can see in the image below how the class of the particle filter in the IQAir Atem X changes at different fan speeds:
Particle filters classed as HEPA-grade at top speed result in a very low CADR. That means that the low-grade particle filter in the Mighty2 allows this air purifier to circulate air through the filter multiple times per hour – and this is a good thing.
Design, controls and app features
A relatively small air purifier with similar dimensions to the old Airmega Mighty and the Airmega 200M.
The design is stylish and compact, with a retro modern vibe that I personally really like.
We used our Mighty2 in different rooms around the house, and it was never out of place.
Coway upgraded the old Mighty design with a laser particle sensor that won’t need regular cleaning.
This makes the Mighty2 much quicker at detecting airborne particles than models with infrared sensors.
You get buttons to set smart modes, adjust fan speeds, schedule timers and control lights.
You also get an air quality indicator light with real-time PM1, PM2.5 and PM10 readings on screen.
Air cleaning performance
We tested the Coway Airmega Mighty2 AP-1512N in our 728-cubic-ft test room, measuring how quickly it removed PM1 particles from the air after we filled the space with incense smoke.
When running at top speed, our PurpleAir Zen sensor shows that the Mighty2 needed 23 minutes to reach PM1 zero. I’ll be honest… I wasn’t expecting that!
Based on this performance, we estimated a PM1 CADR of 260 cfm, which is powerful enough to clean the air five times per hour in rooms up to 390 sq. ft.
This is faster than the original Mighty AP-1512hh, but it’s also faster than the larger Levoit Vital 200S and the Winix 5510 and 5520.
BUT results at top speed won’t tell us the full story… We need to take sound into account because you don’t want to sleep or watch TV next to a leaf blower.
Sound levels
The sound levels of the Coway Airmega Mighty2 range from 35.9 dBA to 56.9 dBA — which is quieter than mid-sized air purifiers from Levoit and Winix with similar performance.
As always, I used our BAFX sound meter to measure how much sound the Mighty2 AP-1512N generates at each of its fan speeds at 3 ft away:
Reaching 56.9 dBA at Turbo speed, the Might2 is still louder than PC fan-powered models like the Luggable XL Ultra and the AirFanta 3Pro, but it is the quietest compared to traditional mid-sized air purifiers from Levoit, Winix, Blueair and even Coway itself.
Running at Speed 2, it reached 42.6 dBA and cleared our test room in 38 minutes – this is a very impressive result for a unit of this size. The Mighty2 was a full eight (8) minutes quicker to clean the air than the next traditional air purifier in the comparison.
Based on the natural ventilation of our test room, I estimate a PM1 CADR of 151 cfm at speed 2, which can clean the air five times per hour in spaces up to 226.5 sq. ft (or 21 m2).
Long-term running costs
Running a Coway Mighty2 will cost you $145.94 per year, combining energy and filter replacement costs.
We used our energy meter to record how much electricity the Mighty2 pulls at each fan speed and while on standby.
At top speed, the Mighty2 draws 49.12 watts, so if you were to leave it running at top speed 24/7 for one year, it will add $75.95 to your energy bill, based on the average electricity price as of June 2026. Compared to older models in the Airmega line, it’s clear that Coway has improved the fan motor’s energy efficiency.
According to Coway, you need to change the filter every 12 months. The genuine filter costs $69.99, so you can expect to spend $69.99 each year on filter replacements alone.
Overall, you will need to budget $145.94 each year to keep your Coway Mighty2 running 24/7 in your home at top speed:
The only mid-sized models in our benchmark that are cheaper to run are the CleanAirKits Luggable XL (with generic filters and super-efficient PC fans), the Levoit Vital 200S (with its cheaper filter replacements and less power-hungry motor), and the 311i Max from Blueair (with its highly energy-efficient fan motor with ionization technology).
However, when it comes to performance, the Mighty2 will offer more air cleaning power than the Levoit and the Blueair, so the additional running cost comes with benefits.
But… Is the Coway Airmega Mighty2 worth it?
Bottom line: Should you get a Coway Airmega Mighty2?
Honestly, I think this could be a possible contender to take the crown from the Vital 200S as the best air purifier for most people…
When you compare it to PC fan-powered units, this new Coway still loses on raw power but for a traditional air purifier, it is one of the best options out there — especially considering how quiet it is:
The older Mighty is a solid air purifier in terms of value for money, but it’s also loud, it’s power-hungry, and it uses an ionizer – which I know a lot of people prefer to avoid.
The Mighty2 has managed to keep all the good stuff from the original while upgrading things in the right areas: you get a stylish design, a more accurate laser sensor, lower energy consumption and better performance at quieter fan speeds.
The only tradeoff is the price…
The Mighty2 is selling for $269.99, and when you add this to the running cost, your total investment in the first year goes up to $415.07:
This makes the Airmega Mighty2 the most expensive mid-sized air purifier to buy and to run in the first year of ownership. But, in my opinion, you’re getting your money back in good performance, good design, and good quality.
Plus, it comes with the coolest slidable, removable pre-filter I’ve seen **heart-eyes emoji**
And let’s not forget about Coway’s 3-year warranty. I regularly hear from people who have been using the original Mighty for 10 years or more, so I have confidence that the Mighty2 will follow in the footsteps of the old one.
The only possible fly in the ointment is the lack of app support, which I know might be an issue for some people. But it’s worth noting that this model works with any smart plug, so you can add it to your smart home setup without downloading another app on your phone.
