If the ventilation pipe is too long you can cut it with a saw shown on an image. Wrap a piece of paper around to make a perfect cut.

Wooden legs were chosen as wood is quite cheap and is normally available everywhere.

To remove the step with wooden legs you can simply buy a piece like a chimney cowl to support the leg.

The lamp holder is made of a plaster board metal profile and the socked is screwed to it.

To function the lamp needs an electronic balast ans you have a small scheme on the ballast to understand how to connect the lamp. The power wire was soldered and then the wire for the motor was soldered as well.

It is a normal 20$ air extractor, normally used in WCs. In order to fit it inside the tube all the excessive plastic needs to be removed.

The motor is attached with an expandable foam.

The Disk Valve is installed to control the air flow. If the air passes to fast the bacteria will not have enough contact with the light and therefore will not be killed.

In the video every step is described.
