Frequently Asked Questions
How often is cleaning required?
Clean the grids at least every two weeks, anytime
The Sharper Image® Quadra® Silent Air Purifier makes a sound or when the Cleaning Overdue indicator illuminates.
How should it be cleaned?
Wipe the removable collection grid with a damp cloth, paper towel or sponge. It is very important that the collection grid be allowed to dry completely before returning it to the main housing.
What is the clean fresh scent I smell?
The scent is ozone, (O3), a combination of three oxygen atoms. (The U.S. government has set safe standards for ozone and Sharper Image® Silent Air Purifiers comply with those standards.)
Which power setting should I use?
If the odor of ozone is strong (for instance in a smaller room), you may prefer to have the power setting on medium or low.
