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.

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.
