Air Safety devices are manufactured for use in demanding clinical environmnets, where safety and resilience are essential prerequisites. Filters and HMEs are rigorously tested to ensure each component offers reliable consistent performance throughout its lifetime. All pleated filters are individually tested before despatch.

The bacterial/ viral filters are manufactured to provide efficiencies of up to 99.99999%.

All products are designed to deliver maximum efficiency in a lightweight, resilient, ergonomic unit.

Clinical application sinclude:

- Anaesthesia & ventilation
- Drug therapy
- Paediatric care
- Respiratory
-
CPAP/BIBAP

Testing provides security. Throughout the development and design stage all Air Safety products undergo stringent testing by internationally recognised Camr Porton Down, Nelson Laboratories, USA, and/or University Hospital Wales – Medical Devices Agency, as well as ongoing in-house testing.

Camr (Centre for Applied Microbiology and Research) Porton Down: 24 Hour Test

Measures efficiency and resistance of a new filter against a known air flow and volume of viable micro-organisms (Bacillus subtilis var niger, 0.7um – 1.0 um for bacterial test; MS-2 coliphage, 0.02um for viral challenge). The filter is then subjected to 98% Relative Humidity for 24 hours to simulate the effect and duration of clinical use, and then re-tested. The efficiency of the filter should be the same or better, whilst the resistance should not dramatically increase.

Nelson Laboratories, Utah, USA

Carry out BFE and VFE tests at increased challenges

University Hospital Wales, Medical Devices Agency: 24 Hour Test

Assesses the likely affect of an Hme (heat moisture exchange) filter during clinical use by measuring Hme weight to assess resistance to gas flow; moisture output, and time taken to reach maximum efficiency.

In-house Testing to BS3928

All Air Safety mechanical pleated filters undergo a Sodium Flame Test prior to dispatch.
