- Hello and welcome back to Mickey's Flightdeck.
In this video I will show you my home build filter system for my CO2-Laser. It is made from 18mm MDF and has four different filters inside.
The first filter is a G4 prefilter.

Then a F9 filter

Followed by an active coal filter

And at the end a HEPA H13 filter

A day only gets better when you see and hear. ``Hello and welcome back to Mickey's Flightdeck.``
I hope I will see you soon back on the flightdeck.
Thanks a lot for another great video! Could you add some details of the filters, what types exactly and where you can get them?
Thank you. I will look it up and add it to the video description.
Hi Michael,
thanks for video.
We have now June 2024. Can you please give short update about your filter system?
Did you need to update the design?
After how many hours of laser cutting did you change the filters?
Until now there was no need to change the filters. The pre-filters show some change of color but not more. I'm not lasering too much and so there is still a lot of life span left over. I think you would have to change them more quickly if you are cutting more wood.
Hi
I want to build a filter too and have watched your video many times and did my research. What really boggles my mind is that you have used an inline fan, while all the places on the internet say that inline fans are not good for enough pressure generation to suck the air through all the filter layers. Those sources suggest that we must use centrifugal fan to generate enough pressure. I want to make my filter just like yours but I am not sure about the fan. Can you please share your fan specs with us.
Thanks a ton in advance.
I also wait for some details about filters and fan :)
I've updated the video description.
@@Mickeys_Flightdeck Hi, can you post details about the fan? It's missing in description. Thanks!
This was a great video. How do you figure out the filter requirements and fan power? 7:35 ish. That is what I am most worried about, making a filter system but the fan is not enough to pull the dust and smoke from the machine effectively.
Honestly I haven't looked up, what the laser needed. I have made sure that the new inline fan harmonized with the filters. I thought it was more importend to match the filter requirements. And I looked fore several videos on youtube where other users have built such a system and looked after the filters they used.
@@Mickeys_Flightdeck Thank you for the reply. I was more meaning how to factor the filter(s) and fan (I have a better understanding, sort of, now) and not really the laser air requirements. Because I can use this also as a general room filter to help with cats as well.
Quick question. Do you really need to exhaust the air? Can it not just go back to the room? This would save a lot on heating costs.
You can do it and when I only have to cut one single piece I do it like this. But the percentage of oxygen in the air doesn't become better with a filter system and it is still used and little bit contaminated air. So I think it is the best decision to get it out of the room. And I'm not living here in an arctic region. The window opening is closed with a 18 mm OSB plate when the filter is in use and the vent is pressing the air to the outside. I think the heating isn't the main cost producer.
