What is Coverage Area (Square Feet)?
The maximum room size an air purifier is designed to effectively clean, measured in square feet.
Definition
Coverage area specifies the largest room size, in square feet (sq ft), for which an air purifier can effectively circulate and filter the air. This figure is often based on the air purifier's CADR and assumes a standard 8-foot ceiling. It's recommended to choose a purifier with a coverage area slightly larger than your room to ensure optimal performance.
Why It Matters
Matching the air purifier's coverage area to your room size ensures efficient and effective air purification, preventing underperformance in larger spaces.
What to Look For
Higher values mean the purifier can handle larger rooms (e.g., 300+ sq ft for living rooms, 70+ sq ft for small bedrooms).
