I'm inspired to build a smaller version of this activated carbon air purifier. I have some questions about drilling the tiny holes to create the mesh, which I understand is needed to allow air to flow through while containing the activated carbon pieces. My questions: 1. Just how tiny are the holes? What size drill bit did you use? 2. How many holes do you need? How do you know when you have enough of them?
Thanks for watching! After more tests there are quite a few changes I’d make to this design. The airflow is not as powerful as I’d like it to be. I think I’d recommend making my first air purifier design instead (link below) and rig up a carbon filtration system in-between the fan exhaust and the HEPA vacuum bag. Also, I have to say, drilling those holes was miserable and enough to drive a person crazy! Here is the other video I’m referring to: ruclips.net/video/MeeAv24VjtA/видео.htmlsi=fE_pVmONPhkchUYx
@@MakerDIY What kind of fan did you use for this activated carbon air purifier? EDIT: Good airflow through a carbon filter requires static pressure. I earlier thought that PC fans would be better, but the cfm ratings assume no obstructions to the airflow. I've built your other bucket-based air purifier design consisting of a bathroom vent fan and vacuum bag. I won't be building another, because other designs are cheaper, more compact, quieter, more powerful, or some combination of the above. I think of it as a white noise generator with some air cleaning ability. So I run it overnight while I'm sleeping. How would you implement a carbon filtration system between the bathroom fan exhaust and vacuum bag filter? Would attaching a cut-to-size carbon filter to the exhaust pipe be enough, or is there a more involved but powerful solution you have in mind?
Will show more of this in my next videos. Thanks for the feedback. I’m thinking of making a narrated version of the video with more details. Is that something you would like to see?
Three buckets are involved, and they seem to be identical. The outer bucket has large outflow holes around the top and large inflow holes around the bottom. The carbon filter is in between. The fan is attached to the lid and pulls air in through the holes at the bottom, up through the filter, and then out through the holes at the top. The filter consists of the bottom portions of the other two buckets. The activated carbon is between these two pieces. Both of those bucket components have numerous tiny holes drilled in to allow air to flow through while preventing the activated carbon pellets from falling through. These bucket components are wedged in so that friction holds the filter together. I'm inspired to build a modified version of this. It will involve smaller buckets, so that means fewer holes to drill and less activated carbon to rinse out and dry out. I will use a PC fan that's smaller and quieter than the one used here. I plan to use the PC fan to draw in air from above and push it down through the filter and out through the bottom. I'll also install a pre-filter for the PC fan and more filtration for the output.

I get what effect you are trying to achieve with the music stopping but it’s way to much. The music stops every few seconds.
Haha dude the edits kinda fire tho
Is the charcoal presented as an alternative to the carbon, or is it part of the build as well? Couldn’t see where it’s added in.
Under the BBQ charcoal it says “Don’t”, as in don’t use BBQ charcoal. I got the activated charcoal from Walmart in the aquarium section.

Could I buy this off you? Or you make one and send it?
Can you show the principal how it works

@@MakerDIY yes with product links please

This sucks,to long
