ELEGOO Mars Mate Air Purifier with Activated Carbon Filter Suitable for Saturn 3 Ultra Mars 4 Ultra and LCD 3D Printers Large Size 210mmx247mmx410mm

I’ll admit, I was a bit skeptical when I first picked up the Elegoo Mars Mate Air Purifier. I’ve been 3D printing for a while now, and like many, I’ve become pretty familiar with the less-than-pleasant odors that come with resin printing. I’ve tried a few different solutions, but none of them really lived up to the hype. That’s why I didn’t set my expectations too high for this one—but wow, was I wrong! First off, the setup is incredibly easy. It’s literally plug and play. I had it up and running within minutes, and the design is sleek enough that it doesn’t take up much space next to my printer. It’s also super quiet, which is a big plus because I usually have prints going overnight, and the last thing I need is extra noise. But the real magic? The air quality. I’m genuinely surprised at how effective this little device is at reducing those strong resin smells. After just a few minutes of running, I noticed a significant difference in the air around my workspace. It’s almost like the smell just disappears. I’ve been using it consistently for a few weeks now, and it’s made a huge difference. No more having to step outside to take a break from the fumes—this thing really gets the job done. Another bonus is the replaceable filter. It’s a thoughtful touch that extends the lifespan of the purifier, and replacements are easy to find and reasonably priced. If you’re on the fence about whether this will actually make a difference, I can confidently say it’s worth every penny. The Elegoo Mars Mate Air Purifier has exceeded my expectations, and I wouldn’t hesitate to recommend it to anyone looking to improve their printing environment. It’s been a game-changer for me, and I’m glad I gave it a shot!

I am very glad I bought this for my Saturn Ultra. The little usb filters could not possibly help. The thing to understand is that resin in an enclosed space *will* smell no matter what. This is not a replacement for proper ventilation per the resin manufacturer’s instructions. That said the VOC numbers in the room I was printing in were fantastic. Rather than being in triple digits/ppb - over 300/ppb observed - when the cover was open, during a 4-5 hour print it was in the low 80s/ppb. The biggest downfalls I see are filter life, filter availability, and fan speed. 1. Filters are recommended to be replaced every 2 months. Which leads into the next issue. 2. Filters can be purchased from the manufacturer, but not Amazon at the time of writing this review. The cost of these filters did give a bit of sticker shock as I was expecting a single filter. I was pleasantly surprised to receive 2 for the cost. 3. I wish the fan moved a bit more air. I didn’t design the device or use any fancy tools to measure efficacy, but I feel like if more resin air was passed through the filter less stink would get out. Overall, I’m very happy with the device, in my opinion it is a must have for resin because those fumes are no joke.

They seem to work as advertised, they're very quiet and I have to hold one up to my ear to tell whether it's on or not. I've been using them for 4-5 days now, charged them when I got them, and again 2 days later, but I haven't let them die so I don't know how long they really last. You go nose blind to the smell of resin fairly quickly, so I can't say for certain that they're a miracle or anything, but I don't have a headache or scratchy throat since using them, so I'm going to keep using them. They are really light, I knocked one off the printer and behind the stand where I can't get to it at the moment, so maybe watch out for that.

Bought these to use inside my printer enclosure to help eliminate odors and VOCs to reduce the strain on my primary filtration system. They work in the sense that they turn on and air passes through them. The issue comes from their overall performance. A few things I noticed are as follows: A lack of power on the actual fan, making it hard to tell if it was even running, Seemingly poor battery life, and the fact it didn't seem as if the provided carbon filters actually did much for air quality and odor control. Pros: compact size will fit most enclosures, rechargeable, affordable. Cons: weak fan, poor battery life, uses micro USB to charge instead of USB-C. Overall: Not a bad price for what's included, but you get what you pay for. Don't rely on it to do all your filtration.

I'm using these with the large size Anycubic Mono X printer. There is enough space inside the print area to place the filter there. It reduced the "resin smell" significantly. It was difficult to be in the room with the small, now it's workable. Initially I placed the filters outside the printer, but placing them inside is when it really made a difference. The set of 2 filters comes with 4 charcoal blocks, so you have a spare once the first stops working. The only "complaint" I have about the units is the long charging time on the built in battery pack. I almost wish it used 2-3 replaceable AA batteries instead, because I usually run those on high use devices in the house. The run time on the built in battery is quite long. They estimate 10 hours. I ran it for 5-6 and it was still working fine when I shut it off. Pretty decent value for the cost.

Despite my printer having built in air filtering, I found it wasn’t enough to eliminate the chemical odor from the photochemical resin. Gave these a shot, and they work! I must caveat, these work with a second layer of filtration, but the difference was as clear as night and day. They’re quiet, and the battery lasts through multiple uses (quoted as 24hr). Very pleased with this purchase, I highly recommend if you suffer or workaround the bad smell of resin.

I bought these in hopes that they would make a difference in the odor of resin printing. I have a Phrozen 4k sonic mighty. I use their Aqua-gray resin 4k which has a medium odor to it but prints really great. I bought these in hopes to bring down some of that odor so during the winter months I could print in my basement. Well lets just say printing with these off versus printing with them turned on makes virtually no difference. If there is a difference its probably so miniscule you won't be able to tell. It's probably more a placebo affect than anything. Unfortunately for me I bought these months ago in preparation for the winter printing inside versus my garage. I should've tested them in an enclosed area sooner. Not worth the money in my opinion. maybe using 4 of them would make a difference? but 2 I can't even tell. Some other reviewers seem to think these are worth the money but I am not getting the same results as them...maybe mine are defective or something? they hardly blow/move any air...
