CLEANING THE PRE-FILTER

The particle pre-filter helps pick-up large airborne particles that enter the rear grille. This pre-filter can be
removed and rinsed by hand under warm water. Let the pre-filter dry completely before inserting it back
into the unit.

POLISH, OR ANY CHEMICAL SOLUTION.
• The IFD filter and pre-filter should be cleaned at least once a month, or sooner depending on the air
quality of the room (See "Removing/Cleaning the IFD Filter" or "Cleaning the Pre-Filter" respectively).

FREQUENTLY ASKED QUESTIONS

How often is cleaning required?
About every four weeks depending on the air quality of the room. You should clean your IFD filter
regularly by gently running a vacuum attachment over it. We recommend washing the IFD filter when
needed but not more than once a month.
Is the IFD Air Purifier considered an ozone generator?
No. Ozone generators produce large amounts of ozone and the EPA considers these unsafe for
household use.
