Boost your ioniser with a retrofit carbon fibre emitter.

Most older ionisers use steel needles as the ionisation tips. This video shows how you can make a retrofit carbon fibre emitter that simply push-fits over the existing needles to make the ioniser much more efficient.
You only really need to make a single carbon fibre point and put it on a single needle to make the ioniser much more effective.

The carbon fibre tape I used is commonly used by the fibreglass industry. It comes on a roll or by the metre, and the preferred type is the non woven stuff like in this listing:- http://www.ebay.co.uk/itm/361177509542
