With viral and bacterial filtration efficiencies of over 99.99+% the Hudson 1605 Universal Inline BV CPAP/BiPAP Filter comes complete with holders as shown! Hudson's filter technology helps stop the viruses and bacteria that often plague CPAP/BiPAP users creating a clean, sterile environment for airflow. The 1605's naturally hydrophobic filter allows maximum filtration with a minimum loss of air flow.
These white ultra fine fiber filters are designed for use with all (older) REMstar Series CPAP & BiPAP Machines. There is a tab on the center of each filter for easy insertion and removal from the machine.
