Description
Update:
Added the configuration as a 3D-Printer filter. It slots into my Filament wall hook.
Also messured VOCs with bme680 airquality sensor. The air quality improves slowly when the printer is printing and the fans are running on max speeds.
Overview:
This is my air filter I use for soldering and 3D-printing ASA and PETG in my enclosure. It uses a Hepa filter for vacuums that you can find easily on amazon. For the second stage I use Carbon Pellets such as found in the Nevermore filter system. As Fans I use 2x 120mm Desktop Pc fans and a cheap PWM controller.
You will need:
Print instructions:
Watch out!!!
Print the CarbonBasket with 12% lines infill and no top and no bottom layers.
The CarbonLit with at least 6 walls and 12% lines infill and no top and no bottom layers.
So that Air can pass but the Carbon Pellets not!!!
I printed all files out of PLA except the parts that say TPU out of TPU. I use 3x Walls and 3x Top/Bottom Layers with 10% infill on the standard parts. The TPU parts are optional and not mandatory for the function of the Filter System.
You need to print more than 1x :
5x HepaHolderClips / minimum 2x
3x TPU_Feet_Base_1
3x TPU_Gasket_Fan
