Hi LarrySabo
I was just going to ask you to measure air particles with a meter. It looks great, I will try to replicate its cabin in aluminum instead of wood. Does the HEPA 14 filter come in various sizes? Do you also have pre-filters before you get to the HEPA filter?
regards
Thanks for the kind comment. The HEPA filter I used was available from a local hardware store and they didn't have many choices. For the V2.1 version of the chamber, I used a larger filter with higher filtration ability (BlueAir 200 series, 18 x 14 x 1.8 inches, 99.97% @ 0.1 microns). I did incorporate a pre-filter (Hammock filter - Duststop Ultimate) which as shown in the pictures for which I provided
the link above, under other stuff, but it's pretty transparent (even folded over several times as it was) so a better pre-filter would definitely be an improvement.
If I were to start over, I'd make it longer; with all the head comb storage boxes piled up along the left edge, and miscellaneous tools in a parts tray and pouch on the side-wall at the right side, there's not a lot of spare room. Two of the BlueAir 200 filters end-to-end would make it 36" wide and you could add a few inches on each side to make it 40" internally, which would be more comfortable. I'd also make it about 6" deeper.
Good luck with your project and please do share your results!
