Kenko Air Purifier HEPA filter pack

HEPA filtration is rated at 99.95% efficiency on particle sizes as small as 0.3 microns, more than sufficient to clean air in any room of the house or office. The HEPA filters will actually allow for increased air filtration over the ULPA filters (rated at 99.999% efficiency on particle sizes as small as 0.12 microns) in the same amount of time.

The recommended filter replacement pack for the NIKKEN Air Purifier is every six months.
Note: Keep the reusable prefilter that came with the unit.
