    OPEN SOURCE AIR PURIFIER

    Woww,awesome work!! I really like the center bolt for the filter housing and the 5 micron and 300 CFM flow rate. I willsoon go on an adventure to find it for a good price because I have never seenit before. You are correct about the quality fans, but I would still recommend usinga pacer. But the best way to find out if you really need it, is to just testit. Thanks a lot for your input and good luck building your own. And rememberto show of your OPEN AIR when you are finished, I would make my day :)

    I will not argue with you, if you want to make it as a fan it’s ok! But anyone can make great use of some extraclean air. And it is not even just about your own: “There are more molecules of air in a single breath of air than there arebreaths of air in Earth's entire atmosphere. Therefore, some molecules of airyou inhale passed through the lungs of Billy the Kid, Joan of Arc, Beethoven,Socrates or any other historical person of your choosing.” - Neil deGrasse Tyson.This quote was one of the greatestinspirations for making the OPEN AIR, because we share the same air all overthe world. So make me and a lot morepeople happy and make it a purifier :) thanks a lot for the complement tough!!

    OPEN SOURCE AIR PURIFIER

    Thanks! The filter restricts the air flow quite a lot. so you need enough static pressure to suck the air trough the filter. In this case using 2 fans does generate better air flow.(I did a lot of testing) Important is the 25mm spacer between the fans where the air has some time become less turbulent before it encounters the next fan. Putting more fans in series will only increase the static pressure, the maximum air flow will never be more than just one fan. http://www.arx-group.com/images/pq13.gif

    Thanks forthe compliment I appreciate it! A metalversion would be really sick. Keep in mind the angle of the blades, but bendingmetal gives a whole lot of other design options. Keep us posted if you decideto make one. Ps. everyonecould use an air purifier ;)

    You arecorrect and I am aware the electronics can be improved! I did try to controlthe fan by PWM but I could not make it work within the deadline :(. To reassure you,the POD is cooled by a rather large heatsink, and is has been working nonstopfor couple of weeks now. Thank youvery much for the feedback!
