What to Check First
- When the PuriCare 360 is running in [Auto] mode, it can be operated in [Boost] mode, depending on the overall cleanliness. (Please check if the Clean Boost is activated.).
- → When used in [High/Turbo], as the fan rotation speed (RPM) increases, the motor noise gets louder, and air speed gets faster. Therefore, the air friction noise increases in the air inlets and outlets.
- Press the [Wind Speed] or [Wind Power Control (Speed)] button to adjust the wind power manually to either [Mid] or [Low]. You can change it to [Low/Mid/High] with the button.
- → When the red lamp lights up due to indoor pollution, the wind speed runs at High, and when it is blue, it runs at Low.
- If it is operated continuously for 50 minutes in good overall cleanliness, it adjusts to Mid level for 10 minutes to detect nearby pollution and circulate the air around it.
- → Here, the wind speed runs at [Auto], and the wind power can be adjusted.
- The noise of wind may be disturbing during your sleep, so please adjust the wind power to [Low].
- → The filter is a passage that air moves through.
- If a lot of dust accumulates, the air purifying performance can be poor and there can be a loud sound of wind. Use a vacuum cleaner regularly to remove dust.
- Use the [e-mail inquiry / phone consultation reservation] menu on the customer support menu of LG Electronics homepage. [Book a visiting service] provides accurate diagnosis and inspection by a professional service manager.
