Key Evaluation Criteria for Buyers
-
CADR vs. Room Dimensions: Always match CADR to room volume. Compact units (150–230 m³/h CADR like Honeywell or Qubo) are tailored for smaller bedrooms/studies, while high-CADR units (300–355 m³/h like Eureka Forbes or Coway) are required for open living rooms.
-
True HEPA Standards: Ensure the unit features True HEPA H13 or NanoProtect technology capable of capturing 99.97%+ of sub-micron particulate matter (PM2.5 and PM0.3).
-
Filter Replacement Economics: Factor in long-term ownership costs. Models with higher filter life ratings (e.g., 8,500–9,000 hours) or washable pre-filters reduce recurring annual maintenance expenses.
