HEPA/Carbon Air Scrubber

There has been a lot of talk about desktop 3D printing and it’s effects inside the home. There are a few studies that show the emission rates of Ultra Fine Particles and VOC’s from 3D printing rising to what could be considered harmful levels. Here is a recent study that was published about it. http://pubs.acs.org/doi/full/10.1021/acs.est.5b04983

After looking for a possible solution for an embedded filtration system for my Flashforge Creator Pro, I stumbled across Rod Laird’s air scrubber couplings for use with a respirator (the kind found in breathing masks) and high pressure fan motor.

I thought perfect; so I ordered a High Pressure Axial Fan and printed up Rod’s fantastic couplings. There’s was a problem though, I could not obtain the resperator Rod uses in the US, so I purchased the Neiko R-621 on Amazon that was recommend in Rod’s thingy comments.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

  1. Bigger diameters will most likely help, slower speed of fans but same air flow is less noise for same output

    Something like, this is also low flow
    Hacked Filter from a Computer fan powered by a USB port



  2. Bigger fans= same airflow less noise

    Mine is low end, cheap air flow
