ELEGOO USB Purifier with Built-in Activated Carbon, Reducing Resin Odor and Fume, Compatible with Mars 4 Series/Saturn 8K Series/Saturn 3 Series/Jupiter SE Resin 3D Printers (Pack of 2)

I spotted these small air purification units whilst looking for some water washable resin. To be honest they looked to good to be true, offering no more nasty chemical odours in a small and cheap self contained unit. I must admit I didn't have high hopes but for the price I thought it was worth a shot. Upon arrival I charged them up, inserted the activated charcoal filter block (4 included), turned them on (they are virtually silent) then placed them inside my printer's enclosure. Astonishingly they worked! The odour is virtually eliminated! An excellent product, I would highly recommend to all resin 3d modellers.

The ELEGOO Mini Air Purifier is a valuable addition to any 3D printing setup. With its rechargeable battery and USB micro B, it offers convenience and portability. It effectively removes fumes and odors, contributing to a healthier printing environment. While it performs admirably, a few minor improvements could elevate it to a five-star rating. Overall, it's a solid choice for users seeking a compact and efficient air purifier.

I wasn't sure if this was a gimmick or a genuinely useful product but I am glad I took the plunge and ordered them. They work well and last a long time when charged; my first one lasted well over 24 hours of continuous running. The fan is very quiet and it fits inside my Photon Mono. It does also seem to reduce the resin smell around the house too, which was the main reason I bought them. Added to that is that each unit has a charcoal block already inside and you get 2 more in the box. Excellent value.

As many reviews below have mentioned these work great, they have ok battery life and make very minimal noise, fit perfectly into my Elagoo Mars 2 Pro and into my Anycubic Photon S.The main issue you will have is replaceable filters for these, however, there is a workaround that will most probably be cheaper than Elagoos offering when they come out. You can purchase large sheets of carbon filters and cut them to size and they work just as well as the original that comes with these.

Does what it says on the tin, it's pretty much removed the majority of the smell of the resins after removing/ lifting the lids of my printers. I print with plant based and water washable! If you work in a studio or environment that doesnt have ventilation to outdoors nearby this is perfect to get rid of the smell.The only thing I'd love is an indicator for when its turned on after pressing the button, right now the only way I know its on is if I put it up to my ear to hear that the fans running. Apart from that, this is it chief.

I bought these to reduce the odour from my resin. I print in a 3m x 2m spare room and it can get noticeably odourous. These are designed to sit on top of the printer base, inside the shroud that comes with the Elegoo Mars 2. They are very effective, and almost silent. But while they come with one replacement charcoal block each you cannot buy any more replacements. You either have to buy a different charcoal block and cut to size, or buy a whole new set of filters. Good product, but silly not to have spare filters available for purchase.

Works well at removing art and electronic odours whilst taking up minimal desk space so ideal for me. Annoyed and disappointed that Elegoo do not mention that replacement filters not available on their listing (apparently not cost effective). So basically they expect users to buy new purifiers when filters run out. Won't be buying their products again then.

Great value for money. Two complete units. They do a good job of reducing any smell and having one on charge and one in use is great although there is nothing stopping you from using both at the same time. I have the Pro that already has filters so I am just using the one at a time. Battery life is good at around 12 hours. A little difficult to see when it's charged as the light doesn't seem to change but a few hours on charge seem to be fine.
