The Ultra Fine Filters are made of white fibers and increase the protection of air pollutants when used with a pollen filter in the System One 60 or 50 Series CPAP and BiPAP machines. It aids in the filtration of dust, pollen, fur and other air pollutants to provide a cleaner airflow to you and protect your devices.

The filters are disposable and are not meant for washing. If you happen to get the filter wet, replace it with a new one and dispose of the other. These filters are meant to be replaced every month depending on the user’s environment. You will typically see the filter change from white to grey. Avoid letting your filters turn black as improper cleaning of the pollen filter and replacement of the Ultra Fine Filter could cause your devices to overwork and eventually fail over time.
