Design & Build Quality
Coway Airmega AP-1512HH
The Coway Airmega AP-1512HH has a more traditional rectangular design. It’s slightly larger but feels more premium, with a front-facing air intake and visible LED air quality indicator.
The standout feature here is real-time air quality feedback, which changes color depending on pollution levels. That’s something you actually notice during daily use—especially if you live in areas with fluctuating air quality.
Levoit Core 300
Levoit takes a different approach with a compact cylindrical design. It’s modern, minimal, and blends well into bedrooms or small apartments.
Because of its size, it’s easier to move around—but it doesn’t include a display or sensor. Everything is manual.
👉 Bottom line:
- Coway = more functional, informative
- Levoit = more minimal, space-saving
Filtration Performance
Coway Airmega AP-1512HH
Coway uses a 4-stage filtration system:
- Pre-filter (captures hair/dust)
- Deodorization carbon filter
- True HEPA filter
- Optional ionizer
In real-world testing, it performs very well against dust, smoke, and pet dander, especially in medium-sized rooms. The airflow is stronger, which means it can cycle air faster.
Levoit Core 300
Levoit also uses a True HEPA 3-stage system, but what makes it interesting is the custom filter options:
- Pet Allergy filter
- Toxin Absorber filter
- Smoke Remover filter
This flexibility gives it an advantage if you have a specific need (like cooking odors or pet hair).
👉 Bottom line:
- Coway = stronger airflow, faster cleaning
- Levoit = more customizable filtration
