Nanofibres to purify air in 'world first'

Remember Revolution Fibres, the company hard at work creating fibres naked to the human eye with potential in the cosmetics, health and electronics markets? Well, now it has developed and produced a new ultra-sensitive air filter for HRV using nanofibre technology infused with the antibacterial properties of manuka.

Remember Revolution Fibres, the company hard at work creating fibres naked to the human eye with potential in the cosmetics, health and electronics markets? Well, now it has developed and produced a new ultra-sensitive air filter for HRV using nanofibre technology infused with the antibacterial properties of manuka.

Technical director Iain Hosie, together with Simon Feasey and Michael Perrett, founded the company two and a half years ago after working at HRV in various guises.

Seta nanofibres, found in the new HRV filters, are about 1000 times thinner than human hair, allowing for millions more fibres to be used in a filter. The Seta filter is a world first and unique to HRV. Completely natural, it uses nanofibre spun from hoki collagen, along with antibacterial properties provided by plant extracts such as manuka. The fibres are held in place by a biodegradable potato starch base, which can be thrown away at the end of its six-month life.

HRV chief executive Bruce Gordon says the Seta filter should help to significantly reduce the level of allergens and dust mites that create health issues for many New Zealanders, especially children.
 
“The launch of the Seta filtration technology links in with our ongoing campaign to raise awareness of the unacceptably high level of unhealthy New Zealand homes and highlights how innovative technologies such as Seta, combined with other heating and insulation solutions, can help address this issue.”
