The Coway Airmega 300S and the Coway Airmega Mighty AP-1512HH are two well-known air purifiers, but they serve different spaces and needs. Here’s a detailed look at their specifications and what reviewers have experienced when using them.
Coverage
According to the product description, the Airmega 300S is designed to clean spaces up to 1,256 square feet in 30 minutes. The AP-1512HH is described as suitable for rooms up to 361 square feet.
Reviewers of the 300S mentioned that it worked well even in larger homes and open layouts. Reviewers of the AP-1512HH emphasized its effectiveness in smaller areas, such as bedrooms.
Filtration System
The Airmega 300S uses what the product description calls a HyperCaptive Filtration System. This includes a pre-filter, deodorization filter, and True HEPA filter, which together reduce 99.999 percent of particles as small as 0.01 microns and 99 percent of volatile organic compounds and odors.
The AP-1512HH is described as using a four-stage system: a pre-filter, deodorization filter, True HEPA filter, and Vital Ion. It reduces 99.97 percent of particles at 0.3 microns and also helps reduce odors and volatile organic compounds.
Smart Features
The Airmega 300S offers a range of smart options, according to its product description. It includes app and voice control, indoor and outdoor air quality monitoring, scheduling, filter notifications, and automatic fan adjustments through Smart Mode. It also has Eco Mode, which powers down when air remains clean for 30 minutes, and Sleep Mode, which reduces noise and power when clean air is detected.
The AP-1512HH, by contrast, is described as offering manual fan speeds, an automatic mode that adjusts based on indoor air quality, and a pollution sensor with color-coded feedback. It also includes a timer, Eco mode, and a filter lifetime indicator, but it does not include Wi-Fi or app-based features.

The Airmega 300S product description does not specify noise levels. However, one reviewer shared that the model operates at 22 to 52 decibels, depending on the mode. Another reviewer described it as “virtually unnoticed” except when running in intensive cleaning.
For the AP-1512HH, the product description specifies a noise range of 24.4 to 53.8 decibels. Multiple reviewers described it as quiet, with one calling it “utterly and completely silent” on its lowest setting.
Maintenance
The Airmega 300S product description mentions a filter alert system that signals when pre-filters need cleaning or filters need replacing. A reviewer noted that the pre-filter can be washed and that replacement filters cost about $43 each. Another reviewer mentioned that while filters seemed costly at first, they saved money compared to allergy medications.
The AP-1512HH product description states that it has a filter lifetime indicator to remind users when cleaning or replacement is required. One reviewer mentioned that replacement filters are affordable and typically purchased once per year.
