Mini Purifier 3D Printer Accessories, Lightweight Ultra Quiet Purifier with High Density Activated Carbon Filter for LCD DLP 3D Printers (Pack of 2)

When I print ABS, (my printer doesnt have an internal filter system) the entire room is filled with a Nauseating smell even with the windows open. These help... a lot. They last quite some time as well so you can leave them running in your printer overnight. I think I had them running for 8 hours or so, so they last a fairly long time. One does just well enough to reduce the smell, but using 2 works even better. they both fit inside my Flashforge Adventurer 5M with and enclosure, just make sure theyre against the wall and the air intake is facing the print bed. Also theyre super quiet, like I have to hold it up to my ear to hear the air blowing into my ear to even tell its on. So theres 0 chance youll hear them over your printer unless youre a bat and your printer is off. For $30 (i bought them on sale for 18) its well worth it to not inhale toxic abs fumes.

I bought these because of the price, and the carbon filter replacements aren't that expensive. I charged one until it was complete and then performed a ~4-hour print. The battery was still going after I had finished my print and left it alone for an hour. When I went to turn off the filter, I lifted the lid and was extremely surprised by the lack of smell, unlike when I lifted the lid this morning to put the filter in.

I exclusively use water washable resin. While it has low oder, it still has a strong smell when printing. These things work wonders in taking care of that smell. I only have to use one, but assume if you use standard resin you'll want to use both. The filter is easy to replace, and replacements are reasonably priced. They have a pretty decent life span. 10kg+ worth of prints and they are still working. The only complaint I have, and why it is a 4 star is because of the battery life. They last about 6 to 7 hours, while a decent amount of time. But if you're running 36 hour printing marathons, i.e. 40k large scale warmachines, large busts, or multiple plates of anything, these can go out many times on you. While I can rotate them out, standard resin users will be faced with having to charge them. And there is no warning they have gone out other then the resin smell. A little trick I learned, they will run while plugged in. Running the cable out of the printer will cause oder to leak, so I've gone to using cellphone backup batteries. The one I have was given to me, but it adds another 7 hours or so to the time, and can charge inbetween charging the units. Just get a really short and stubby USB cable, you don't want it falling into the vat, like me.

Pretty small units but they work well. Batteries often last a couple days. I turn them off at night when the printing is done but they otherwise run the whole day. They do help keep the smell down so id say it’s a good value.

It feels like these can run forever. They noticeably reduce the smell of my 3d printer. They are tiny, and I can easily fit both in my printer. You can barely hear these run.

Notice the improvement in air quality when printing the more toxic ASA and ABS filaments. Helps with other filaments though not really needed as much. Mount them up to plate level or in printer and they will clean the air, noticeable difference. Easy placement. Can be mounted in holder or even upside down in blower tunnel (print separate).

These are for reducing smell and not filtering the air of contaminants...

For their size, I am impressed. They have lasted 8 to 10 hours each. I have no issues with battery life. I can tell the difference when using them inside of my enclosure. Depending on the smell of the filament, I will use two at once. Low noise. I can barely hear them. I chose these because I did not have a suitable place to exhaust using a fan and hose.

These things reduced the resin smell to almost nothing!

Me encantó que la batería dure 14 hr no se ha quedado sin descargar el aparato en tiempos prolongados de impresión. El tamaño es perfecto para mi Anycubic Photon Mono 4 y reduce considerablemente el olor de la resina. Trae dos flirteos de carbono uno para cada purificador. Uso únicamente uno y los voy alternando, los cargo inmediatamente cuando termino una impresión, así nunca me hace falta. Lo único que me gustaría saber es cuánto dura el filtro de carbono ósea cuando debo reemplazarlo. IMPORTANTE: aunque en el video parece hacer mucho ruido es realmente silencioso, imagino que el micrófono del celular es sensible pero es casi perceptible el sonido del purificador encendido.

Solo se escucha un zumbido cuando se enciende que se reduce al tener la tapa de la impresora puesta, reduce el olor de la resina también, la carga de la batería dura como 8 horas, trae cable pero no adaptador de corriente

Work a dream and are so quiet you forget they are on, they are the perfect extra buffer for clearing out the fumes from what’s left over from prints before opening up the hood.
