You Need To Protect your Lungs from your Laser Cutter | LaserPecker Air Purifier Review

[@SianaGearz]

Normally HEPA filters are at a disadvantage for room air filtration, due to their high impedance; but as a flow-through filter directly hosed to the source of pollution that's exactly the right way to use them, and this one seems adequately designed and fit for the task. I don't think i would trust its VOC filtering performance though purely because it's a lot of unknowns and the little pollution meters don't thoroughly detect them, and this is why you should still vent outdoors. There can always be stray unforeseen hazards such as binders and additives in your materials that you end up lasering that are not actually laser-safe.

Those are very good points, thanks for sharing. When researching how to try and quantify air quality, I fell down that rabbit hole of detecting VOCs and found exactly that. You'd need a number of specialty sensors tuned to the narrow range you'd be expecting in order to accurately quantify them. So trusting a single number on a relatively inexpensive sensor might give some information, but not the full picture. I'd love to see folks with more experience in air quality share their perspectives on this kind of filtration.

Would this work for filament 3D printers? Resin 3D printers? It seems it should work, maybe the VOC of resin is too much, but the website does not even mention that - maybe because they squarely aim it at their own laser engravers - or because it wouldn't work for printers? Or would it be overkill? Sorry for so many confused questions!

The technology would be the same, filters and activated carbon. LaserPecker is definitely a laser company, so they probably didn't do much testing or market research on the printing side of things. It would be a topic I'd be interested in experimenting with though.

Hi do you think i could use this with my xtool s1 as its far more cost effective (with the right pipe fittings) ??

[@HoffmanEngineering]

Absolutely, ive used it with my xtool S1. It worked great.

I use an inline 4" shower fan and a few metres of ducting shoved out of a window for a fraction of the cost of Laserpecker's overpriced filter box.

[@HoffmanEngineering]

Yeah, if you just want to vent outside than you don't need this air purifier. But if you wanted to filter the air before venting outside (close neighbors, others in a shared open air workshop, etc), then this would be a decent option if you didn't want to source all the parts/filters/etc yourself.

I’m looking to buy an extractor. I have an xtool M1. Do you think this machine would be suitable? Thanks
