Key Features to Consider (With Comparison Table)

When shopping for a smart air purifier, focus on these critical features:

• CADR (Clean Air Delivery Rate): Measures how quickly the purifier removes smoke, dust, and pollen. Higher CADR means faster cleaning.
• Filter Type: True HEPA (H13 or H14) is essential for capturing fine particles. Activated carbon helps with odors and VOCs.
• Smart Features: Wi-Fi connectivity, app control, voice assistant compatibility, and real-time air quality monitoring.
• Room Size Coverage: Ensure the purifier is rated for your room size (e.g., 300-500 sq. ft. for a bedroom).
• Noise Level: Look for sleep modes under 30 dB for undisturbed rest.
• Energy Consumption: Check wattage; efficient models use 15-55W.
• Filter Replacement Cost: Factor in annual costs ($30-$80).
