what it does

Assure® DBF provides solutions for respiratory care.  

The Assure DBF Compressor Inlet HEPA Filters are installed in the inlet air stream of a respiratory device, such as an oxygen concentrator.  Once installed, these HEPA rated filters remove bacteria and viruses with greater than 99.97% efficiency.  

In addition, these HEPA filters remove the atmospheric dust and debris found in typical oxygen concentrator environments thereby helping to remove contamination that can cause premature compressor failure.  The silencer design helps to reduce noise levels.
