BACTIGUARD Air Filters.

Bacteria, yeasts and moulds require certain criteria in order to thrive, such as dirty damp and warm conditions. What better than some air filtration systems, areas of air conditioning plant and ductwork where high levels of contamination have built up?
Since the early 1990s studies have confirmed that air filters support the growth of micro-organisms that are associated with the phenomenon of Sick Building Syndrome. By the mid-1990’s it had been established that microbial colonisation of filters may constitute a hazard before they fail, i.e. before the pressure drop across the filter reaches the recommended standard for replacement. Under such conditions, contaminants can be quickly and easily spread throughout ductwork and into occupied areas causing a potential risk to the health of building occupants.

While micro-organisms may be brought into the building via the air handling unit, people and activities within the building also generate micro-organisms. Where recirculation systems operate, the micro-organisms are continually transported throughout the building.

An extensive development programme throughout the 1990s has resulted in the Nationwide Filter Company’s range of BACTIGUARD air filters. BACTIGUARD air filters have the singular ability to eradicate a wide range of micro-organisms on contact rather than simply inhibit their growth (independent reports available).

BACTIGUARD air filters are available in the grades shown below and the Bacti-cell Air Filter Cartridge.

Anti-Microbial Filtration

BACTIGUARD F/S air filters are available in a range of synthetic materials and grades

BACTIGUARD F/S products are also available in filter grades, F7, F8 and F9. .

NOTE: The anti-microbial treatment of BACTIGUARD Air Filters is not surface sprayed onto the face of the air filter, but is applied during fibre manufacture, to provide effectiveness throughout the filter depth.

Anti-Microbial Treatment

BACTIGUARD coatings are also available as a lasting system treatment for ductwork, air conditioning systems and plenum chambers – or any surface where bacterial growth may occur.

On 1 January 1999, the Health & Safety Commission’s Code of Practice for Workplace Health, Safety and Welfare came into effect for existing buildings.

Regulation 6 of this Code relates to ventilation and requires effective fresh air supplies to the work place. Clause 33 of this Code recommends every mechanical ventilation system, including air conditioning, to be regularly and properly cleaned, tested and maintained to ensure it is kept clean and free from anything that may contaminate the air.

Ensure system cleaning expenses are kept to a minimum by:

A. Selecting the correct NFC filter grade

B. Utilising BACTIGUARD coatings and air filters as a lasting system treatment.

Presence of high microbial loadings (bacteria and fungi) can lower the quality of indoor air.
