<p>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.)</p>

<h5 class="sub-tit">The sound of the wind changes depending on the [Wind Speed], [Speed], [Booster Speed].</h5>
<p class="info-desc">→ 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.</p><p>Press the [Wind Speed] or [Wind Power Control (Speed)] button to adjust the wind power manually to either [Mid] or [Low].<br/> You can change it to [Low/Mid/High] with the button.</p>
<h5 class="sub-tit">When it is in [Auto] mode or [Auto Clean] mode, the fan rotation speed (RPM) automatically changes, so the noise goes louder and smaller.</h5>
<p class="info-desc">→ 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.</p><p>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.</p>
<h5 class="sub-tit">In [Sleep] mode, the display is turned off a few seconds after entering [Sleep] mode.</h5>
<p class="info-desc">→ Here, the wind speed runs at [Auto], and the wind power can be adjusted.</p><p>The noise of wind may be disturbing during your sleep, so please adjust the wind power to [Low].</p>

<h5 class="sub-tit">If there is a lot of dust in the ultrafine filter and is clogged, it can make a loud sound of wind.</h5>
<p class="info-desc">→ The filter is a passage that air moves through.</p><p>If a lot of dust accumulates, the air purifying performance can be poor and there can be a loud sound of wind.<br/> Use a vacuum cleaner regularly to remove dust.</p>
