Charcoal Pollen Filters

[FarmerPug]

Eurocar parts has a bit of a sale on, and i ordered up everything to service the 406 for £30 including the oil, one of the things ordered was a pollen filter, there was an ordinary type available for £4 which i bought, but a carbon one is £14, is there any advantage to having a carbon one?

FWIW, I know that charcoal filters will clean most chemicals out of water, maybe they help keep CO and CO2 levels down inside the car?

Carbon filtering must be very effective, the NBC suits we used to have in the army had a charcoal impregnated fabric

The Volvo's cabin filter is a Carbon one and I have to say the interior has always stayed very fresh to be fair. They call it an 'active' multi filter, it's electrostatically charged and impregnated with active carbon.

Extract from Baldwin Filters website:
The charcoal in the filters is treated with chemicals and heat to give it specific odor-control properties. Charcoal traps odor-
causing gases by adsorption (not absorption), and therefore holds the gases on the surface of the charcoal treated media.
Because charcoal is porous, the filter has a very high capacity for trapping noxious gases.

Other sites I have looked at include that they keep out odours from sewage farms, bonfires and hot tarmac. As I drive round the M25 past the sewage farm between Heathrow and Chertsey, i may well invest in one now.

The only issue with carbon is its finite life when I worked in a composite workshop we had to change our respirator filters monthly due to the high levels of airborne pollution but if you left the filter on a side it would only be 3months before it was ineffective anyway.

There's plenty of noxious gasses in my cabin of a morning.....

Gandhi's revenge?

My 407 also has the carbon cabin filter... so does my kitchen extractor hood...
