What should I do if I won't use the air purifier for more than 30 days?

Remove the HEPA Filters from the unit and wrap them in an air tight plastic bag. Remove the Odor Reducing Pre-Filter and place it in an air tight plastic bag. Additionally, clean the air purifier at least once every 3 months before extended storage using only a dry cloth—do not use water, wax, polish, or any chemical solution.
