How to Choose

• Room Size: Always match the air purifier’s coverage area (measured in square feet) to the dimensions of the room you intend to use it in. For optimal performance, look for a unit rated for a slightly larger space than your room.
• Filter Type: A True HEPA filter is essential for capturing 99.97% of airborne particles as small as 0.3 microns, including allergens and fine dust. Activated carbon filters are crucial for odor and smoke removal.
• CADR Rating: The Clean Air Delivery Rate (CADR) indicates how quickly an air purifier can clean a room. Higher CADR ratings mean faster air purification. Look for ratings suitable for smoke, dust, and pollen.
• Noise Level: Air purifiers operate at various noise levels, typically measured in decibels (dB). For bedrooms or quiet living spaces, opt for models with a low decibel rating on their lowest setting, often below 30 dB.
• Smart Features: Many modern air purifiers offer Wi-Fi connectivity, allowing control via a smartphone app, scheduling, and integration with voice assistants. Air quality sensors that automatically adjust fan speed are also a valuable feature.
