Coway AirMega 150 vs 200 – What’s the same?

Type & Use

The Coway AirMega 150 and 200 are two air purifiers from the same brand. They’re made of plastic so they won’t rust for years, and you should mount them straight to the ground for maximum coverage. You can also use both devices in your home or office for fresh air 24/7.


On average, you get 99.9% clean air indoors, excluding gas. If there are concentrated gasses around the cleaner, the efficiency drops to 93% in the worst case. You can minimize this by changing the filter frequently to always get the best results.


Both Coway air purifiers come with a five-year warranty covering all internal/functional parts such as motor and electronics. One exception to the warranty is that you will not receive a filter cover as it starts deprecating from the date of purchase.

Quality Indicator

Real-time quality indicators are equipped with two air purifiers to constantly monitor the air in your room. There are 4 coloured LEDs covering different quality levels. Blue means good, green is decent, yellow is unhealthy, and pink/red needs to be cleaned up immediately.

Coway AirMega 150 vs 200 – What’s so different?


If we compare the designs of the two air purifiers, we have a clear winner. The Coway AirMega 200 comes with a sleek and beautiful frame that you can place anywhere in the house. However, the Coway AirMega 150 has such a minimalist look that many people want to install it outside the window.


The Coway AirMega 200 is significantly larger than the 150-option due to a wider and taller body that takes up more space. The unit is also 3.8 pounds heavier than the AirMega 150 for increased ventilation and overall reach indoors.


The Coway 150 is available with a total of three filters, pre, deodorization and HEPA, while the other unit comes with four. An additional dust filter is attached to the Coway 200 to help you clean the room better. You can also wash the pre-filters on both units from time to time to extend their life.


The Coway 200 is an upgraded model that offers wider coverage than other air purifiers. With the AirMega 200, you get a maximum range of 364 ft², while with the Air Purifier 150 you can easily manage more than 214 ft² of space. So, if you have a large room, you can opt for the latter option and get a better cleaning range.

Power Usage & Noise

As a larger device, the Coway 200 uses more power than the others. The AirMega 200 exhibits a maximum power consumption of 38 watts, while AirMega 150 averages under 35 watts. Apart from that, the Coway 200 air purifier makes a bit less noise than the others, but you won’t find any air purifier interfering with your work.

Air Flow

The Coway 150 is available in four speeds that you can control or leave everything in auto-mode, but the Coway 200 only operates in auto-mode. The Coway 200 has two-speed settings, and the system controls the speed completely so you don’t have to manage it every day.
