ELEGOO Mini Air Purifier with Activated Carbon Filter and Universal Adaptor for LCD,DLP,MSLA Resin 3D Printer（Pack of 2）

I do love the brand, but sadly these are useless, they do nothing at all, smell is still and not even reduced by 10%, i put one in the machine and one outside the machine and still nothing, i wish i knew i would have invested in a big air filter instead of this

Eliminates smell by a very noticeable margin. Just one work super good. Super long battery life. Very compact and can fit inside of printer.

Despues de unas impresiones les comento que si disminuye el olor en gran medida tal vez un 85% no lo cancela al 100% pero si hay una gran mejoria. Lo recomiendo. Efectivamente trae 4 filtros de carbon, 2 en la caja y 2 dentro que hay que saar de sus bolsitas. Seria de agradecer que el led indicara que está funcionando, pero en realidad es mejor asi, puesto que cualquer luz podria afectar nuestra resina. creo que es un excelente producto, y si me parece que debe ser compra obligada si compras una ipresora de resina. Aunque se lleva casi todo el olor, siempre es recomendable que la habitacion este aireada, para evitar risgos.

I took a chance on this product based on all the positive reviews but wasn't expecting much. I've got to say though, these little filters actually do work and work well! They are extremely quiet, compact, and they fit perfectly in my Phrozen Sonic Mini 4K, on either side of the Z-axis arm. Fully charging them can take a few hours or more but they seem to be able to last a good 16 hrs with a full charge. As for their filtering capability, these little units do a surprisingly good job; the resin smell from my printer is almost entirely eliminated. My wife noticed the improvement right away when she came down to the basement and commented that the "stinky smell" was pretty much gone. I'm running a print right now and forgot to charge the filters and the resin smell is definitely much stronger without the filters running - so they definitely work! Interestingly, my package came with two replacement carbon filters and one already installed in each unit, which isn't mentioned in the product description here. I've been so happy with these little guys that I bought a second set for backup / extra filters. If you do a lot of printing and don't have a well-ventilated dedicated space for your printer, these are definitely a must-buy in my opinion.

Sí reducen considerablemente el olor a resina y no son ruidosos. Traen un carbón extra y aguantan buen tiempo sin cargar. Indispensables si tienes tu impresora en espacio cerrado.

Cumple muy bien su función de eliminar el olor de la resina, son fáciles de usar y muy prácticos.
