Understanding Air Purifier Performance
What is CADR?
Clean Air Delivery Rate (CADR) measures the volume of filtered air an air purifier delivers. Higher CADR means faster air cleaning. All Blueair purifiers are AHAM Verifide for CADR ratings on tobacco smoke, pollen, and dust.
What are Air Changes Per Hour (ACH)?
ACH indicates how many times per hour the air purifier can filter the entire room volume. Blueair models are rated for 4.8-5 ACH in their recommended room sizes, meaning complete air refreshment every 12 minutes.
Room Size Recommendations
Choose an air purifier that matches or exceeds your room's square footage. Blueair provides AHAM-based room size recommendations for optimal performance.
