As per the subject, has someone measured the effectivness of the VentoBox on reducing the VOCs? I have my P2S in my study room where I sit for several hours during the day and, as you can imagine, can’t be ventiled while I’m there in Winter. I really would like to start printing with PC and Nylon but I’m really too “scary” about VOCs & bad company (I already went through a cancer and I’d like to avoid to repeat the experience)….some data? I repeat, real measured data not opinion, please
I don’t have real data but I can assure you that printing with ASA with the Ventobox doesn’t help much - there’s still a distinct smell. So I would imagine in your specific situation it would not be enough.
Did you mean scientific or “scientific”? If you actually meant scientific, no, if you meant a measurement where the person starts by saying “I bought a VOC meter off Amazon and…” there is that guy on youtube who has them as a sponsor, you could look at his stuff.
Looking at the website I don’t see any quantitative claims about VOC removal at all, except that it does it.
not scientific, nor in a P2S but a X1C :
I have a bentobox, inside the printer with an activation switch, and an Ikea Vinstrad air filter, which I can activate manually, or keep in auto mode
I noticed that while printing ASA the smell is there, but lower, and the Ikea air filter seems to be less active
I’ll have a real test when I have more ASA parts to print
I am going to buy a Ventobox but only as the first filter. I added carbon filters to my dehumidifier and I have a huge Levoit filter with a Hazard VOC filter in it and in a small garage it is barely enough. You have to buy an Air quality meter and continually test to get the right set up. It took way more Air Flow than I expected to get any real results. Less about Hepa more about air flow is my advice. I will also say in my opinion if you smell it get out of the room regardless of what the meter says.
just to be sure we’re on the same idea :
I see posts about “ventobox”, acting as a filter, while the solution I use is a “bentobox”
per the Voxel website
I have order this FNATR filter box to help with odor and VOC emissions. I also have bought the Vento - 2 stage also. Again we are a couple weeks out from getting our P2S so this is our plan. Anybody have experience with this combo so far.
Eh, I’ve taken the Vento off. H2S. I didn’t find any advantage. I haven’t noticed a difference in odor at all, and none of my sensors have gone off, that’s the end of my experience. Keep in mind that if you want that filter you can only get it from VoxelPLA who sucks at shipping and service. They seem to be proprietary for that design.
There are other options on MakerWorld to try that use more readily available filters. The Bento box was created by the same guy. They work a bit better, more intrusive.
I have both. I cant tell if they even do anything im just using pla/petg and it seems like im still getting less irritation in my sinuses vs nothing. This is also in a small room in the winter no windows open.
Chemist here. There are definitely different qualities and grades of active carbon. VOC adsorption is a factor of flow rate, surface area, quantities and adsorption capabilities. 1 - I have no idea if that provided carbon is good. 2- if you get your own, get the right one and dont cheap out.
I know there are uses and needs for stronger filaments, but just to mention it PLA emissions are low enough not to make any noticeable difference on my airgradient monitor, neither as VOC or microparticles. This is measured in the same room. I’ll do a test close to the printer and share results.
I came so close to ordering this yesterday. I can’t say why I didn’t, and I may still. I just want to know how well it works. ■■■■ it’s just a box with a fan that holds a filter. Shouldn’t be that hard to build your own really.
I have a P2S in my home office and am also concerned about the air quality.
I am thinking about getting the chamber exhaust kit and then lead the exhaust air via a tube either outside or through a filter.
Would that also help with printing PLA and PETG?
I am a bit confused because the advertising focuses on ABS and the filtration that happens at the end of printing. But what I am after is something that sucks out the air also while printing.
Would that work with the official chamber exhaust kit? Or does that not make sense because it would change the temperature in the chamber to aggressively?
The exhaust kit will use a filter. It’s in the “box” mounted on the back of the printer from the kit. You’ll have to print those parts.
Short answer is yes.
ABS has a distinct smell that can bother some, and is mostly unhealthy to breathe in. The filtration kit will help remove the smell and most harmful particulates. Can’t say it will remove all because I don’t think it’s been tested.
If I read the exhaust kits description it looks like it works like the H series. With that the vents are open while printing PETG and PLA. If the filter is present on the exhaust it will help with those filaments. As for temp change PLA and PETG print well with a cool chamber, you’re not using heat so there’s not much to worry about.
This is without any filters and reflects what i measured on my open frame printer: I ran a 12+h PLA print with an air quality monitor (Airgradient One: decent quality) right beside the printer, right in front of the printer, and even inside the chamber under the bed. The room was mostly shut with no air purifiers running.
No extra PM 2.5, PM 0.3, PM 1 or PM 10 compared to the rooms base level.
No extra VOC compared to the rooms base level.
The monitor is fairly sensible and nothing shows up. There is probably something, but completely negligible compared to common air pollution and the rooms base level.
Here are the graphs.
The spike on PM is someone having a smoke on the balcony, door ajar. Had it not been raining there would also be spikes when opening the windows (dips in VOC)
The spike in VOC is the espresso maker in the room where the printer is.
The room base level is 60-100, same as during print: the best example is the flat line when it was running undisturbed at night.
Joined also: The other PM measures, again, same as room base level. Outside air when is doesn’t rain or is windy is systematically worse. (Average EU city).
On top of being handy and less bad for the environment, this is why I favor (and recommend) PLA for anything that isn’t a particularly demanding mechanical part. For “fairly strong” there is PLA+. I haven’t yet needed “indestructible”.
Maybe not the answer you wanted, but rather than “experiement” with all these VOC filters, just get a tent for the printer (either a 3d printer tent, or a re-purposed plant grow tent) and pipe the tent’s extractor fan out of the window.
Thats what i want to do overall but right now i can’t do to only having space for it in a place where id need to run hose in an inconvenient way across the hall or room. Lol
