MDH Defence CBRN units utilise the NATO No 1 Composite Filter. Designed by MDH Defence, the filter is compliant with the performance specifications detailed in the NATO Tryptych AC/225 (Panel VII) D251 and AEP 54.
For use during periods of conflict or raised threat, the Live Filter offers protection against known chemical and biological warfare agents as well as many toxic industrial chemicals. Offering protection for up to 17 occupants, the filter is in service with many different armed forces worldwide.
MDH Defence CBRN units can also be fitted with a HEPA only filter, designed for use during peacetime operations but where dust and particulate filtration is still essential. As a lower cost consumable, it provides significant protection against particulate ingress but reduces life cycle cost.
All MDH Defence CBRN units can be fitted with a training filter to be used for peacetime operations. With an infinite life and low initial outlay, it reduces life cycle costs to a minimum whilst allowing the CBRN Unit to be operated as required for training and maintenance purposes without consuming Live or HEPA filters.
