Key Metrics: Choosing Your Air Purifier
CADR Rating Explained
Clean Air Delivery Rate (CADR) measures how quickly the purifier filters smoke, dust, and pollen. Higher is always better for larger rooms.
The Importance of True HEPA
Don't settle for "HEPA-like". True HEPA filters capture 99.97% of particles down to 0.3 microns, including allergens and bacteria.
