3 smart presettings for different airborne pollutants

Healthy air protect
HEPA Replacement Filter lifetime is accurately calculated based on indoor pollution level, air flow and operation time. The healthy air protect alert lets you know promptly when it is time to replace the filter. If the filter is not replaced promptly, the appliance stops functioning -to avoid ineffective purification. So you are assured of healthier air always.

Low noise
When in silent mode, the purifier turns down its fan speed and noise level to allow a comfortable night’s sleep.

Smart light control
Both AQI and the light on the UI can be dimmed and/or turned off avoid light disturbance for consumers.

VitaShield IPS technology
Vitashield IPS with its aerodynamic design and NanoProtect Filter has a boosted clean air delivery rate up to 344 m3/hr* (according to China GB/T 18801-2015). It can effectively remove ultra-fine particles as small as 20nm, effectively reduce harmful gases such as formaldehyde, TVOC and odor. Removes up to 99.9% bacteria.

Aerodynamic Design
Aerodynamic architecture boosts efficient airflow.

Pollution Mode
Indoor PM2.5 levels can increase far above local guidelines because of activities like cooking. Pollution mode can accurately detect invisible indoor air pollutants in real time, and then boosts the air purifier’s speed to reduce harmful particles, gases, for a cleaner air output.

Allergen Mode
The Allergen Mode includes a special event-detection algorithem from AeraSense – a professional grade sensor that can detect daily events such as shaking pillow or a vaccume cleaner passing by. After accurately detecting these events, the purifier will automatically gives an extra booste to airflow to instantly reduce the risk level of allergens to a minimum.

Bacteria and Virus Mode
Bacteria and Virus particles are the ones seldom detected by air sensors. Hence the most effective way to reduce these particles is to significantly boost the airflow and increase the air exchange per hour. This mode boosts the Air flow, then the high quality HEPA filter in the purifier effectively captures the bacteria and virus by upto 99.9%, ensuring cleaner air output.
