Nanoparticles or ultrafine particles (UFPs) can be dangerous because of their chemical composition but especially because of their size (less than 100 nanometers).
When inhaled, UFPs can be trapped in the smallest areas of the lung’s alveoli, which are tiny sacs covered with blood capillaries where oxygen and carbon dioxide are exchanged between the bloodstream and the lungs. UFPs are small enough to pass directly from the lungs and into the bloodstream. This way they accumulate in other organs of the body such as the brain, the liver, or the spleen.
And the particles need not be toxic in and of themselves in order to cause problems or poisoning : even PLA particles (which are currently widely believed to be non-toxic) can build up in the lungs and cause serious harm.
As for VOCs, they can include any number of different chemicals and in varying amounts. For example, the VOCs released when an ABS filament is melted can contain 10 to 20 different chemicals, most notably Styrene, a chemical classified as being toxic, and possibly a carcinogen.
Have you noticed this strange and irritating smell when you’re near your 3D printer? It is actually a mix of harmful gases and nanoparticles. This is due to thermoplastic fusion. Professionnals in the thermoplastic industry or folks with an average sense of smell alike, you have already smelled this melted plastic and you know it can’t be good for your health.
With one 3D printer operating continuously in a 45 m3 (1600 ft3) furnished and conditioned office space (complete air renewal rate of once every hour), we observe an ultrafine particles concentration of 58 000 particles/cm3. This is more than 11 times what we observe in a typical home, office or school ambient air.
Regarding the gases : In this configuration, the predicted styrene concentration is about 150g/m3, which is 20 times more than the highest styrene concentrations measured in commercial buildings in the U.S. In France, particle pollution is the 3rd cause of death : more than 48 000 people die every year as a result of particle pollution. We do not accept even more pollution in our homes! Source

"I couldn’t be happier with my Zimpure. It’s the 3D printing solution that I had been waiting years for."
"If you’re looking for an inexpensive and portable 3D print filtration system, this might be it."
It was important for us to test and evaluate our new and innovative way to filter nanoparticles and gases issued by 3D Printers.
That’s why we worked with a specialised laboratory (LSCE, CEA) to evaluate and improve our product.
We are now proud to provide an efficient, reliable, compact and affordable filtering solution for all 3D printer users!
Consumption: 15.6W, 12V.
Size: L 204mm, l 159mm, h 164mm.
Air Flow: 70L/min.
Filtration rate: 99% for nanoparticles, 90% for gases.
With our new injected molded case and acoustic foam filling, Zimpure makes little noise. When your printer is on, you will barely notice any noise from Zimpure. Check out this video to see how much noise a Zimpure really makes.
The filters have been tested to last (at least) 500h (4Kg of ABS).
To get an idea of how long the filter will last regarding your habits, look at your printer's information section. There you have access to the hour counter of your printer.
We recommend that you write down the hour counter value, and when at +500 hours, change both filters.
2 sets of filters (1000 hours of filtration) cost 19,9€. Note that a set of filters is already installed on your Zimpure.
Additional filters will are available here! We will add them into your Zimpure box.
Because 3D printers release both nanoparticles and gases, we need to use two different filters : A particulate filter (N95), filtering 99.9 % of the nanoparticles, and an active charcoal filter (ABEK1), filtering more than 90% of the gases (VOC). The filters we use are manufactured by 3M. We’ve tested them in laboratory, they are very efficient. Read more in our study report.
You can throw them in the bin, they can’t be recycled.
You can already check if your printer's suction head is online. Print it and follow the tutorial to see how Zimpure will fit on your printer.
If your printer is not in the list, check out this page to see our “Let’s make it compatible” process. !
We attended the experiments and measurements, and took part in the writing of the study report. Roland Sarda Esteve from the LSCE lab was in charge: the instruments used are not trivial, and we are not qualified to use them.
Our suction heads are made to have the same filtration rate at the same distance from the extrusion nozzle of any 3D printer. We have designed Zimpure to be efficient with all filaments.
We manage the production ourselves, at our facility in Southern France. This way, we can control each stage of the production process and reduce the risk of problems along the way. All our suppliers are ready and standing by to ship the components.
No, both the the silicone pipe and the suction head are lightweight, and the pipe is very flexible: they do not interfere at all with the mechanics of your printer.
No. The airflow rate is so low that it doesn’t affect the overall temperature in the enclosure.
No, we’ve tested it on different printers, with different materials, and printing quality doesn't change.
In order to make Zimpure efficient, compact, and very silent, 3D printed parts are not enough. Zimpure comes with an injected molded case, vibration absorption foam, acoustic foam, and high quality components that cost a lot if you buy them on your own. Also, we have conducted lots of tests in a laboratory to provide you with an efficient and reliable product. The instruments used for nanoparticles and VOC measurements with the precision we had are rare and expensive.
Contrary to what is usually thought, PLA is also a source of nanoparticle and VOC emissions. Plastic filaments are also never pure ABS or pure PLA. Filaments are made up of a complex mixture of different polymers, in order to provide the best printing quality, layer adhesion, warping resistance, flexibility, and other parameters. Many different toxic compounds can be found from one filament to another. Like most plastics, PLA has the potential to be toxic if inhaled and/or absorbed into the skin or eyes as a vapor or liquid (i.e. during manufacturing processes like 3D Printing).
Yes you can use it with your enclosure. If your enclosure is almost perfectly airtight, you can use Zimpure as a filtration system without the suction head. Just place it inside the enclosure, or run the tube into it. If your enclosure isn’t really airtight, use Zimpure with the suction head.
