Seeking a superior air purifier replacement filter, we looked to a manufacturer in Holland for a F8-rated filter, made by CAMFIL FARR and compliant with EN799 and rated by EUROVENT – globally recognised as the leading professional organisaton for overseeing the development of heating and ventilation systems worldwide. View the rating. These deep-pleated filters have a wider filtration surface than most filters used in New Zealand HRV systems, and are manufactured from continuously spun glass fibres with a progressive thickness, enabling dust to be collected across the whole surface area.
The material is also embedded with dust collecting agents, further enhancing its ability to collect particles from the air. HEPA filters are also available as an optional extra, when very high emphasis is placed on air purity – for example, in the home or bedroom of an asthmatic person or child.
