Filters for GoodKnight 420 and 425 CPAP

CPAP Filters for GoodKnight 420 and 425

Ultra fine filters add another level of filtration for the Puritan Bennett GoodKnight CPAP machines. When used with a pollen foam filter, air pollutants are trapped in the filters prior to their ability to enter the user's airflow being provided by the machine.

CPAP machines draw from room air to provide the necessary air pressure to the user and these filters help reduce the chance of air pollutants from getting into the user's air pressure.

These disposable filters are not cleanable and should be replaced monthly. Failure to properly keep a clean filter in the machine can cause the machine to over work and eventually completely fail.
