Ultra fine filters are by far the most efficient in regards to filtering harmful particles out of the air, filtering 99.9% of all harmful airborne bacteria and viruses. They are also often referred to as "disposable" due to this efficiency, and the frequency with which they need replacing (typically every two weeks).

To maximize filtration efficiency, the ultra fine filter should be used simultaneously with the foam pollen CPAP filter (sold separately).
