Step 1: Cut Pc Blade

cut all the blade on a pc fan,drill 4 hole on a moni dv disk and glued 4 laser

Step 2: Place Plasric Bottle on the Machine

tape with black tape and let 4 hole for the air extraction,place 4 screw for making the leg of the machine

Step 3: Plug a Usb Cable

plug a switch and after take a usb cable and take the red and black wire for powering the machine

Step 4: Now Just to Put the Switch on and See the Beautiful Light

    Not to down your instructable, but can;t laser radiation severely impair your eye-sight or even make you blind?Just thinking...

    Its impossible that you can purifie air with that.Air is a compound of 78.08% nitrogen,20.95% oxygen, 0.93% argon, 0.038% carbon dioxide and 1% water vapor that can varie.You cant realy say theres "bad air", you may consider it has a high quantity of bacteria,CO2,humidity...etc.The lasers dont do anything to them facts, all your doing is producing a stream of fotons throw a bottle, thats not going to change the quantity of humidity or C02 and the only way it could kill bacteria would be a powerfull laser that beamed still in one spot and mabe then the heat would kill the bacteria(that would only happen on the surfice of what your aiming at).Sorry to say but that laser thing doesnt do anything to the air.

    Even if he cannot purify anything with that ... is just another way to enrich your lab with "freaky technology" ... next to jacob scale and tesla coil...this will look gorgerous on the shelves of your lab ...

    Or, like hivoltage said, you could try get hold of a UV laser diode then try with that with some sort of protection from the beam

    Yeah probably but then you would have to mess about with an inverter to drive the tube off 5v but the USB port might not have enough current... :)

    You're right - it would defeat the purpose to make it not-USB and not-laser. Still, though, it would actually do something...

    2- where do i get this laser parts and for how much ??
    please i am in the dead line for doing this project so i need ur help as soon as u can

    I don't believe this "purifier" is actually capable of killing bacteria. The only way red light can kill a bacteria is if it causes enough localized heating to the bacterium to kill it, which would require a very high power laser. light in the UV-C range can cause damage to the DNA of a bacteria or virus and effectively prevent it from reproducing and render it harmless. UV-C is around 250nm while this uses red laser light at around 630nm, not nearly a short enough wavelength to do much besides looking cool.

    This is not purifing air, maybe something with carbon pellets would but not this..
