We hope you are healthy and staying safe. Are you running the air purifier with the ionizer on? If yes, then the white dust is caused by the ionizer being used for an extended time. This is caused by negative ions exiting the air outlet, evidence of the ionizer&amp;rsquo;s air cleaning effectiveness. You can remove the dust with a soft brush or clean, damp cloth.

We hope you are healthy and staying safe. Negative ions help air purification by attaching themselves to very small airborne particles in the room. These particles take on a negative charge and may join with positively charged particles such as dust, pollen smoke, and pet dander to form larger particles. These larger particles are then more easily captured by the filter system. The ionizer in this appliance produces less ozone than the UL established limits of 50ppb (parts per billion). However, in high concentrations, ozone can be harmful to birds and small pets. To prevent ozone buildup, we suggest using the ionizer in well ventilated areas with the fan on. <div class="bvseo-author">Answered by: Holmes Consumer Care</div> <div class="bvseo-pubdate">Date published: 2021-03-13</div> </div> </div> <div class="bvseo-question-answer" data-questionid="7021413"> <h2 class="bvseo-question"> Do you guys have pictures of the previous model?
