CLEANING AND MAINTENANCE To get the most out of the PuRXium Air Purifier, it's best to clean the washable pre-filters once a month or more often, depending on where the air purifier is placed and if you have pets. The HEPA H13 filters should be cleaned once a month using the brush attachment from a vacuum. The air purifier will automatically tell you when it's time to change your filter when 2,500 hours of purification have been reached. The filter replacement light will illuminate in red when it is time to replace the HEPA H13 and active carbon filters on the unit.
