I'm sure there are some of you out there, like myself, whose room is full of dust, allergens, and other debris.  After looking at the prices of some of the purifiers on the market, I decided to make one myself, and construct an instructable on how to recreate it.  

Step 1: What you'll need

You will need the following parts:

A foot of 3 - inch diameter PVC tubing
A 3 - inch diameter computer fan (mine was 12V)
An AC/DC adapter, with a DC output the same as your fans
Filter for a room air conditioner
Toggle switch
Hose clamp for the 3 - inch pipe

I already had the fan and adapter laying around, but everything shouldn't cost more than 20 dollars.

You will need the following tools:

Drill and various bits
Soldering iron + solder
Hot glue gun + sticks

<p>Cool, but will it remove farts?</p>
I got the best air purifier, which is the Winix PlasmaWave, from Amazon a couple of months back and it has worked wonders for me and my family. Got a great price, you can see the discount here: http://amzn.to/10akR10 - You have got to see the real reviews on this air purifier, you will not be disappointed. <br>
wow awesome now have to figure away to block off the air from the glass door one issue solved in my room thanks i wonder if i could hide this and still work i love this project very simple oh i am rambling again sorry
How well does this filter works?
did something similar in Iraq for the dust!!! used bat powered fans off Ebay and some MRE boxes! used Wet wipes as Filter!!!! it work well for about a month ! the fan from ebay kept breaking down! lol<br>
I like this, especially since I can do it almost completely with stuff I have in my shop. I am going to add another filter section with a cartridge of activated charcoal. I'll post the results...
Very nice, very inspring! Now I find myself eyeballing my old computer with the toasted hard drive- Mouhahahahaaa! Those little fans have so many uses, but I didn't think about hooking one to an adapter. Thanks!
Nice. If you added some aquarium activated charcoal or something similar, between the filter layers, it could also help to remove fumes and chemical odors. I don't know where you find it but there is a product that is basically corrigated paper coated with charcoal
Putting a layer of washed, activated charcoal, between the filter layers will do the same thing. When I had aquariums, I used to make my own filters after I found out that the charcoal was just activated charcoal, and could be bought in the pharmacy area of most stores. You wash, or rinse off, the charcoal to eliminate the dust before using.
