- Replaceable and effective filter for your Laser Engraver.
Are you tired of changing air filters?
Do you want a replaceable filter which is free of charge? Well, we have one - DIY Water filter.
Remember chemistry lab lessons from your student days. And specifically - remember water filter for gasses.
It surprising how well water filters air passing through it.
Just use a 20 litre bottle to make the filtration element. Use some plumbing hardware easily available in local store.
Make the system modular and stackable.
Put two filters in row, if necessary.
Use the inverted bottle to catch water droplets and feed them back to the main filter.Use another box, if necessary, for additional water safety or to put any additional filtration bags there.
Not necessary after the system has been tested, but could help anyway.Use some silent vacuum cleaner as the suction power.
I use AEG VX9-2-ÖKO vacuum cleaner as my suction pump, but any other will do too.
Use your imagination, test and experiment.
Now you can have a permanently clean air in your laser engraving workshop, even without the need to open window or let the air exhaust out.
Looks great. Does it filter out dangerous fumes and the smell of engraving leather? :)
If it does, then why is there not an affordable solution?
Thank you! I have not tested it on leather, but I think - yes, it will filter fumes out. I took the idea from chemistry lab, where simple water bubble filters are extensively used exactly to filter out any harmful fumes. Works very well in my case (engraving wood). You can cascade the filters, put two bottles in sequence, if you wish. As a final step you have to catch the water droplets (thats is what the inversed bottle is for) and you can also put an extra box of vacuum filter paper, to see the cleanness of air passing through the system. Or you can let the vacuum cleaner used as suction pump to do this final job. I have observed some colouring of vacuum filter, probably from still unfiltered wood oils, but the smoke and smell is almost completely gone. Experiment. Good luck!
