ELEGOO 2PCS Mini Air Purifier with Activated Carbon Filter and Universal Adaptor for LCD/DLP/MSLA Resin 3D Printer

The media could not be loaded. I ordered the ELEGOO carbon filter replacement and it works perfectly! It came well-packaged in a sealed plastic wrap, which I really appreciated for keeping it clean and protected. The design was slightly different from the original model that came with my machine, but it fit just fine and functions just as well—no issues at all. It's been doing a great job filtering out odors, and I’m happy with the quality. Definitely a solid replacement option!

Haven't had and gripes about them. Some complained about not having a light when it's running. I don't think it needs it. It's very easy to tell when they are running. They're quiet, but they do make sound, and you can feel them running. Light feels like an unneeded power drain. As for power, some people had issues with that too. I'm not seeing it. On more than one occasion I turn them on for a print in the early evening, and they are still going by late morning when i remember I had stuff on the printer. On top of that, they went another 6-8 hours a couple of those times as i queued up another print. A single charge seems to last... I dunno, like 18 hours for me? It's just been a non issue.They're good for the price point.

These little air filters definitely work. I put them in my Phrozen Sonic Mini 4K with Anycubic Eco UV Resin (they fit inside the printer no problem) and they basically suck up all the odor during printing. I print in a small room with an air intake and printing fumes always worried me (I wear a respirator when handling resin), but I could probably print in my living room now since these little Elegoo filters work so well at eliminating odor.The only downside is they are terribly designed. There is no way to tell if they are on. The light on the front is only for charging, which is just inane. The motor/fan is so quiet that you can’t hear them when they’re on either, which would be great if there was some other way to tell that they are on. It’s also hard to tell when they are fully charged as the light is always red. It would be better if it turned green when fully charged. There is also no way to check battery life so you basically just have to charge after each print to ensure they don’t die mid-print. Lastly, as others have noted, you can’t buy replacement filters. Elegoo has said something about not being able to store them so they don’t sell them, but that’s very odd as they already come with a second pair of replacement filters that have to be stored until use anyways. Pretty sure you can jury rig filters with some cheesecloth and aquarium charcoal beads but it’s a big miss to not have prefabricated replacement filters for these.Would love to see a second gen version of these that fixes these large flaws. Eventually it would be great to see charcoal air filters integrated into a 3D printer itself, but for now at least these will do to help reduce odor during printing.

Elegoo Saturn owner. I have only one printer, and using just one of these clears out my entire room of scent, which is useful in more ways than one.... I tested it by doing an 8 hour print. I left mine OUTSIDE the machine by the two little fans in the back, and it almost immediately started making the area smell normal, and these resin printers are smelly, ha! I also keep it on while washing/curing my prints, and for about an hour after I leave the room. Then I come back, and no smell.Tested it by going for a walk to clear my nose of any smells (its a thing, look it up) and even after cold winter air, no smell that a human can pick up on.Buy it, and you likely only need to use one. I have the main one that I use, and plan on using the second one as a backup in case anything happens to the first.Comes with two extra filters, so one for each. Or for my particular needs, three (including the basic filter from my "spare" unit).BUT, BIG BIG BUT....You can not find the little activated charcoal filter anywhere. I have looked. I have found similar, but none in the appropriate dimensions, and none that were cheap enough for me to validate shaving the piece down that much.I will be instead buying some activated carbon cotton sheet as a filter. Cut several little squares (as many as needed, obviously) down to size and just layer them in the place where the little charcoal filter would normally go.Great product, works as good as advertised or even better.Stupid filter problem that NEEDS to be fixed.I say buy it, and also add some of that activated charcoal cottons sheets to your cart with it, save yourself the trouble in the future.

Amazing Works like a description Thanks
