In today’s article, I will compare two air purifiers from the popular brand Coway: the Airmega 150 and the AP-1512HH (Mighty).
The Coway Airmega 150 is a newer model in Coway’s lineup and brings a fresh design to the market. On the other hand, the Coway AP-1512HH is a proven, reliable unit and is one of the best air purifiers we’ve tested.
The Airmega 150 has a CADR of 152.8 CFM (259.6 mÂł/h), while the AP-1512HH delivers a CADR of 233 CFM (396 mÂł/h). This means the AP-1512HH is better suited for larger rooms.
Aside from performance, the Airmega 150 offers a more stylish design. Both models include an air quality sensor, but neither supports a smart app.
Our Verdict
It’s true that Coway improved many aspects with the Airmega 150 air purifier. It’s quieter, consumes less power, and is still highly efficient.
However, the Coway AP-1512HH has a much higher CADR and delivered better results in our airborne particle removal tests, which is why I would consider it the better buying option.
If you decide to go with the Coway Airmega 150, you won’t go wrong. It’s a solid choice, but keep in mind that it’s best suited for smaller rooms, while the Coway Mighty is slightly more efficient overall.

Performance Test – Comparison
Since these two air purifiers have different CADRs and are designed for rooms of different sizes, we tested their airborne particle removal efficiency in two rooms of different dimensions.
We measured their performance using a Temtop laser particle meter. Each test lasted 60 minutes, with both devices running at maximum speed the entire time.
Particle Removal Tests - Comparison
We placed the Coway Airmega 150 and Coway AP-1512HH in two separate tests and measured their performance using the Temtop laser particle meter.
In the first test, performed in a 194 sq. ft. (18 m²) room, the Coway Airmega 150 improved air quality by 94%, which is an outstanding result.
In comparison, the Coway AP-1512HH improved air quality by 96% in a larger 320 sq. ft. (30 m²) room.
Overall, both air purifiers delivered excellent results, with a slight edge in efficiency going to the Coway AP-1512HH.
Noise Level Test – Comparison
We tested the noise levels of these two air purifiers using a specialized measurement tool that records sound on a dBA scale.
The good news is that both Coway models feature three fan speeds, which makes comparing their noise levels much easier.
Noise Level Comparison
Comparing the Coway Airmega 150 and Coway AP-1512HH noise levels at minimum and maximum speeds.
At the lowest speed, the Coway Airmega 150 is slightly quieter, producing just 40.1 dBA compared to the AP-1512HH’s 42.3 dBA.
At maximum speed, the Airmega 150 is quieter, measuring 59.2 dBA, while the AP-1512HH reaches 63.5 dBA.
The results are clear: the Coway Airmega 150 is better optimized for noise than the AP-1512HH.
Operating Costs – Comparison
Not only is the Airmega 150 better optimized for noise, but it also uses a more efficient 35W motor. In comparison, the Coway AP-1512HH is powered by a 77W motor.
Power Usage Comparison
Comparing the Coway Airmega 150 and Coway AP-1512HH power use at minimum and maximum speeds.
If you were to run both devices at their maximum speeds, your electricity bill would increase by about $6.06 per year with the Coway AP-1512HH, compared to just $2.52 with the Coway Airmega 150.
Considering that both air purifiers use long-lasting filters that typically need replacement only once per year, it’s easy to conclude that the Coway Airmega 150 is significantly cheaper to maintain annually than the AP-1512HH.
