Best Air Purifiers for 3D Printers [With HEPA and Carbon Filters]

If you’re a 3D printer enthusiast, then you’re probably well aware of the pollutants that are emitted when printing. In this article, we’ll be discussing the best air purifiers for 3D printers, with both HEPA and carbon air filters.

Printing in a well-ventilated room is always advisable, but if you want to take things one step further, an air purifier is a great way to eliminate any harmful emissions from your 3D printer.

Which Air Filters Work for 3D Printers?

There are three types of filters that are effective at trapping particles emitted by 3D printers: HEPA, carbon air filters, and PECO filters.

HEPA Filters

Airborne contaminants come in many forms, from large particles that are easily visible to the naked eye to smaller microparticles that can only be seen with a microscope. During the printing process, 3D printers release a fine mist of ink particles into the air, known as ultrafine particles, or UFPs. These particles are small enough to bypass the body’s natural defenses and enter the bloodstream, where they can cause respiratory problems, heart disease, and cancer.

HEPA filters are designed to trap particles as small as 0.3 microns in size, which means they are effective at capturing most UFPs. However, True HEPA filters are even more effective, with the ability to trap 99.9 percent of particles as small as 0.1 microns. This makes True HEPA filters the best option for reducing exposure to UFPs emitted during the 3D printing process. You can also find out if HEPA air filters remove asbestos from the air by checking our article here.

Carbon Air Filters

A carbon air filter is a type of air filter that uses activated charcoal to trap pollutants. Carbon filters are effective at trapping a range of pollutants, including volatile organic compounds (VOCs), which are released when plastic is heated during 3D printing. VOCs can be dangerous to your health, so it’s important to remove them from the air you breathe.

But, while carbon air filters are good at removing VOCs and odors, they are not as effective at trapping UFPs. This is because the pores in activated charcoal are too large to capture such small particles. Moreover, carbon air filters need to be replaced more frequently than other types of air filters, as they lose their efficiency over time.

PECO Filters

There are many dangers that come with 3D printing, chief among them the release of toxic fumes into the air. But a new technology promises to change all that, and it’s called photoelectrochemical oxidation (PECO).

PECO filters out both particles and VOCs from the air, permanently destroying any toxins. What’s more, PECO can destroy carbon-based particulates, which is what most plastic molecules are made of. In other words, PECO filters are the best way to keep your air clean and safe when 3D printing.

California has banned the sale of denatured alcohol as a fuel, but it's not clear if it can still be used to clean 3D printed parts.

$22 at Amazon

Breathe Free: Air Purifier

Resin printing is not carcinogenic, but may have an unpleasant odor and fumes may irritate the eyes and nose. Always use resin 3D printers in a well-ventilated room, but an air purifier definitely won't hurt. It will clear the air of any significant irritants. It also works on any mold or smoke from your workshop.

$90 on Amazon

These things matter

I know I'm telling you to be as careful as a broken record, but that's because it's important. I love this hobby and I want you to enjoy it. However, to do this, we must be careful and respect the tools. Don't worry about chemical burns.

Nitrile gloves are absolutely essential if you want to work with resin in liquid form or immediately after it has been printed. From personal experience, you want to wear safety glasses too.

On the other hand, the 3D printing community found this little pickle strainer for cleaning and sold out in one day! When we find something that makes our lives easier, we jump to it, and we've bought so many of them that when you add a resin printer to your Amazon cart, it prompts you to buy that too. Brilliantly.

Introduction How the printer pollutes the air How BOFA filters

What is 3D printing

3D printing is also known as additive manufacturing. This means that the product is created by adding material in layers. The process is controlled by a coordinate XYZ robot with digital control. Printers work with plastic or metal. The material is fed to the deposition point in the form of wire or powder. The printer is melting the material. Then it connects to the previously applied base.

A 3D printer will produce objects of complex shape. This favorably distinguishes the additive process from the subtractive one, when excess is removed from a large piece of material. Machining, laser processing, soldering or welding generate more contamination. And a lot of material is wasted. 3D printing does not consume a lot of extra material. It appears to be a clean process, but it still pollutes the air.

Anyone using 3D printing needs to be aware of the health risks. The 3D printer seems safe. But it can generate toxic fumes and hazardous substance particles. Technological processes that transform the material pollute the air in the workplace. This applies to cutting, engraving, thermal decomposition in a laser machine, soldering with a toxic flux, etc. Molten metals and polymers are no exception.

Why is a 3D printer dangerous?

Ultrafine particles

Heating a substance causes the release of solid particles, droplets and vapors. They may be harmful if inhaled.

European scientists are gradually revealing the dangers of 3D printing to health. According to 3D Printer Emissions Report plastic melting releases small nanoparticles of material into the air. They cannot be seen without special equipment. But that doesn't mean they are safe.

PLA plastic nanoparticles are used in pharmaceuticals as a means of delivering drugs to various organs, including the brain. Cosmetics use the same effect. Ultrafine particles penetrate the skin. By themselves, PLA particles are not toxic. But no one knows about the consequences of accumulation in human organs. Nanoparticles condense into relatively large formations. It is known for certain about harmfulness of nanoparticles of soot from automobile exhausts . They are associated with degenerative brain diseases, such as Alzheimer's disease.

ABS plastic is toxic when melted. Nanoscopic ABS particles are just as toxic. These particles are very small. During inhalation, they enter the brain through the olfactory nerve. They spread throughout the body through the bloodstream. Most organs can get rid of them naturally, but the brain and lungs become clogged for a long time.

In fact, particles as small as 10-200nm easily enter the bloodstream through the lungs. Their toxic action differs from the original substance in the usual shapes and sizes. According to study by the Italian Institute of Health and Consumer Protection nanoparticles are deposited in the lungs in greater quantities than the smoke of an electronic cigarette.

Gases or vapors

Molten ABS gives off a particularly unpleasant odor. Other plastics including nylon, HIPS and HDPE emit the same toxic fumes but have less odor.

Polymer materials can vaporize some of their constituents. Dioctyl phthalate is often added to them for flexibility and mold resistance. During high heat or laser treatment, benzene is released in hazardous quantities. And while working with PVC, HCl aerosol condenses in the air.

The high temperature in the area of ​​the printer head causes the air to expand. Vapors quickly spread in the work area along with plastic particles. Thermal degradation products of polymers are shown in the diagram below.

How does BOFA work?

A smoke extractor is an extractor hood with filters placed in one device. She got her name at the time when she removed the smoke of a soldering iron or a laser engraver. But these same devices with special filters are also suitable for a three-dimensional printer. The smoke extractor block for the printer is not much different from the soldering block.

3D printing is sensitive to changes in air temperature. Therefore, he is afraid of drafts. If you are using a small open printer, then the polluted air can be removed with a conventional smoke extractor. In order not to disturb the climate in the printer, select the minimum air suction speed.

If your 3D printer model is closed, there is a protective cover, then you can install a cleaning curtain. During operation, while the printer window is closed, it can be turned off. But it will clean the outgoing air when you open the box to take out the finished product.

If your printer is large and completely enclosed, then it will most likely have built-in pipes for connecting the hood. They can be connected to a smoke extractor with large filters. It can operate continuously or turn on at the command of the printer. The fume extractor captures dirty air and returns it back to the printer so as not to change the air temperature during the printing process.

3-stage filtration

A complete smoke extractor is equipped with three filters. The first is the pre-filter. It does not let in coarse dust, so as not to clog the main fine filter with it. The fine filter is HEPA. Particles of all sizes, including aerosols and nanoparticles, settle on its fibers. The gas filter completes the cleaning. It consists of densely packed activated carbon granules with interlayers of fiberglass. Activated carbon traps VOCs and nanoparticles that HEPA missed.

Smoke extractor against exhaust

The cheapest way to remove smoke is a duct fan and air ducts. The emission of polluted air through the window is prohibited by SanPin standards. And the smoke extractor has advantages.

  • Good air purification from all kinds of solid particles and aerosols
  • There will be no odors from melted plastic or metal in the room
  • You will be sure that your health will not suffer
  • The microclimate in the 3D printing machine will be stable
  • Supply ventilation with heating or air conditioning is not needed, as for the hood in the window

Eliminate the harmful agent

The hood with filters will solve the problems with harmful emissions from 3D printing with polymers and metal powder.
