AirMac-400H Replacement Pre Filter

Replacement Pre-Filter for the AirMac-400H Portable HEPA Air Purifier

The metal mesh pre-filter is designed to capture large particles including hair, dust, lint, dander & pollen, so the true HEPA filter can do its job. The smaller microscopic particles flow through the pre-filter where they are captured by the HEPA Filter. 

To clean the pre-filter, remove and shake out or brush off the accumulated dust and lint. If this is not adequate, a vacuum cleaner may be used or the prefilter can be cleaned with an all-purpose alkaline detergent to remove tobacco smoke or cooking grease stains. Thorough rinsing is required after each cleaning. The pre-filter should be completely dried before inserting it back into the unit. The pre-filter will need to be replaced after repeated washings as the material will naturally begin to deteriorate after about 2 years.
