Losma discusses the difference between green air filters and other filters on the market.

Standard filters are made up of a metallic structure, glass fibre or synthetic fabric (plastic coming from petrol).

Losma discusses green air filter attributes

These materials contaminate with mineral or synthetic oils and metallic particles should be separated from each other.

It is not possible to separate these materials easily, as this takes time and can be dangerous.

This means that this kind of waste is to be stocked into ’special waste’ and deposited, for example, in the ground.

This generates not-treated pollution.

Green filters are made solely from natural fibres and when contaminated by oil are treated by through a thermal waste programme.

Natural fibres are also ’burned’ in this way but, as they are not special waste, they can generate energy.

The small metallic particles are left behind during the burning can be collected for reuse.

This is very different from stocking hazardous materials.

The production of metal, glass fibre and synthetic filters is polluting in itself, and uses energy.

The natural fibres do not need energy for production and have no carbon impact as they produce the same amount of carbon that they take.

In the presence of humidity and oils, the filtering capacity is increased, but the characteristic of the fibres avoids mould generation.

The natural fibres we use have been declared by the Journal of the American Medical Association in 2007 as ’useful to fight bacteria’s as staphylococcus’, which typically are contained in the synthetic filters.

The type of fibres contained in green filters are very long and strong, and are 70 per cent cellulose, containing small amounts of lignin (8-10 per cent).

The diameter of the fibres is between 12 and 25um and between 16 and 50um, which allows sub-micron pollutant particles to be captured.
