This product is a small portable air purifier and is only suitable for small areas. It is not suitable for strong air purification in large rooms. When using the device, a gap for air intake and exhaust needs to be reserved around it. Do not block the ventilation holes on the device body to avoid affecting the air circulation effect. The USB power supply voltage needs to be matched to avoid using abnormal power supply devices. The negative ion emission module is a consumable component and its performance will gradually decline over time.

Keep the intake port clean during daily use, regularly wipe the surface of the device body of dust, and avoid excessive dust accumulation in the ventilation holes, which can affect the device's working effect. The machine cannot directly absorb solid formaldehyde. It only serves as an auxiliary air improvement measure. For new houses, ventilation through opening windows is still recommended. Do not place it in a humid environment, away from water sources, to prevent water from damaging the internal circuitry.

The compact body does not occupy too much space for placement. The USB power supply is compatible with various scenarios. With multiple speed settings, it can assist in air purification in desktops, bedrooms, and small spaces inside cars. It is suitable for users who prefer lightweight and simple air treatment devices.
