Hunter PermaLife Air Purifiers: 30747, 30748, 30750

Permanent cleanable filter effectively captures 99.5% of particles as small as 0.5 micron in size from the air that passes through the filter.

The PermaLife Filtration System is a cleanable filter that never has to be changed, only cleaned. If you notice a decrease in air output or an increase in noise at any time during normal operation, the filter may be clogged. When clogged, the filter should be cleaned with a vacuum cleaner and upholstery brush attachment. Do not use water or liquids to clean.
