Why use a breathing  lter
Breathing  lters are designed to prevent microbial cross contamination which can occur via patients, ventilator breathing systems and respiratory equipment. Their use has been widely recognised as an effective method of reducing cross contamination and has been recommended by a number of medical associations1.
The threat to patients is varied
Patients requiring respiratory support at home may be exposed to the risk of cross contamination from the equipment, breathing systems or the environment. Documented areas of concern regarding infection from breathing systems include Hepatitis C, Mycobacterium tuberculosis, blood in sputum and the SARS virus.
Long term ventilated patients may be at risk from pseudomonal growth in the breathing system and in water bath humidi ers. The strategic use of an effective breathing  lter protects both the patient and equipment bi-directionally, helping to prevent infection.
Effective use of  lters in the homecare environment can also help protect the respiratory equipment which the patient relies upon, as well as helping to optimise its function and helping to prolong its life.
