Airmega AP-1512HH Mighty
The Coway Mighty is the industry standard for efficiency and longevity, consistently outperforming units double its price in CADR (Clean Air Delivery Rate) tests. Its combination of a true HEPA filter, a long-lasting motor, and an eco-mode that shuts off the fan when air is clean makes it the most cost-effective high-performance unit available.
Quality & Materials
Features a four-stage filtration system: a washable pre-filter, a deodorization carbon filter, a True HEPA filter (capturing 99.97% of particles down to 0.3 microns), and a bipolar ionizer (which can be toggled off).
Evidence & Testing
AHAM Verifide with a CADR of 233 (Smoke), 246 (Dust), and 240 (Pollen). It is CARB (California Air Resources Board) certified for zero ozone emissions.
Brand Transparency
Coway provides full specifications for CADR and energy consumption. Filter replacement indicators are based on actual air processing, not just a timer.
Value Assessment
At ~$200, it offers the best CADR-per-dollar ratio of any purifier on the market. Filter replacement costs are reasonable (~$50/year).
Why Not Alternatives?
Unlike the Levoit Core series which has faced scrutiny over HEPA marketing claims, Coway uses AHAM-verified true HEPA filtration. It also offers significantly higher airflow and durability than the budget-focused Winix models while maintaining a smaller footprint.
