3D printing has recently become a very popular hobby thanks to commercially available 3D printers. But many hobbyists are unaware of the toxic fumes, dangerous VOCs, and ultrafine particles that are spread into the air during 3D printing.
Industrial 3d printers utilize extensive ventilation and filtration systems to deal with these toxins and VOCs. These systems are not viable for small home workspaces or labs.
For smaller spaces, Air purifiers can substantially reduce the number of toxins, VOCs, and burning odors in the rooms. Air purifiers can also filter the ultra-fine particles UFPs generated during resin printing.
Here is the list of best air purifiers for 3d printers.
3 Best Air Purifiers for 3d Printers
1. Levoit core 400S
The sleek and stylish design of the Levoit Core 400s will look great sitting next to your 3D printers.
It comes with an H13 true HEPA filter which can easily remove ultrafine particles released during 3d printing.
The high-efficiency active carbon filter will help neutralize odors, VOCs, and dangerous fumes released by a 3D printer during printing.
Levoit Core 400S is one of the quietest air purifiers on the market. At the lowest fan speed, the noise level is 42.1db (the sound level of a refrigerator), and at the turbo fan speed, the noise level reaches 59.9 dB (the sound that an air conditioner makes). This quiet operation is best for a workspace, as you can focus on other tasks without being bothered by the sounds.
The Levoit core 400s has a CFM of 260 and can purify rooms up to 403 square feet. At the turbo fan speed up to 260 CFM, it takes in a power of 35 watts; at low fan speed, it takes in a power of 5.8 watts. The Levoit core 400s is an efficient air purifier.
Smart App features provided in the Levoit Core 400s make it unique. The advanced controls provided in the app make the air purifier even better in day-to-day use. 3D printers sometimes take a long time to print 3d structures. The timer option provided in the app can help schedule the air purifier to turn off when the 3D prints finish.
Levoit Core 400s purifier comes with an air quality sensor and indicator. The air quality sensor measures real-time particles and displays the data in the smart app. This is a very neat feature that lets you check the room’s current air quality at any time.

4. ELEGOO Mini Air Purifier
The ELEGOO mini air purifiers come from a 3D printer manufacturer of the same name. These purifiers come in a pack of two and are small compared to other air purifiers on this list.
These small and affordable air purifiers are meant to be placed inside the chamber of 3d printers. It consists of a small brick of activated carbon filter, effectively removing odors, VOCs, and fumes at the source.
The filter lasts 3 to 6 months, depending on your 3d printing. Its filters are hard to get your hands on. Some DIY solutions are popular among the masses. A carbon filter usually used for fish tanks can be used in this air purifier, or stacking some carbon filter sheets inside will get the job done.
These air purifiers have a 2000 mAh battery which lasts up to 24 hours, and are simple in design. They are designed to be put inside the 3d printer chamber and adsorb VOCs. The ultrafine particles somewhat settle down due to the enclosed chamber.

How toxic is 3D printing?
Most commercially sold 3D printers use molten polymer deposition MPD or fused deposition modeling FDM. An extruder melts the resin up to 320 C and builds layers upon layers to create structures. While the resin is melting, toxins, chemicals, and harmful VOCs are created.
Many 3D printer enthusiasts deny such harmful effects of 3D printing. But if you look at 3D printing, you are melting plastic and plastic fumes are hazardous to health.
Some argue that toxins and VOCs don’t reach you, and you’re safe. If you can smell it, you’re inhaling it. If you inhale the VOCs and ultrafine particles, they can get stuck inside your lungs and enter your bloodstream.
The problem with plastics is that they don’t decompose naturally. That particle might stay in your system for over 1000 years. It’s no hidden fact that plastics are carcinogenic.
Types of 3D printer Pollutants
3d Printers produce two types of pollutants
- Ultrafine particles UFPs for short, 0.1 to 0.01 microns in size.
- Volatile organic compounds. Fumes, odors, and gasses all are VOCs.
Frequently Asked Questions (FAQs)
Is a HEPA filter good for 3D printing?
There is large speculation in the online community that HEPA filters are useless when filtering ultrafine particles released during 3D printing. True HEPA filters ensure 99.97% removal of particles under 0.3 microns. This doesn’t mean that below 0.3 microns, nothing gets filtered. NASA researchers found that 0.3-micron-sized particles are the hardest to filter.
Brownian motion affects particles below 0.3 microns, meaning that they travel in a zig-zag pattern while flowing through the air. Hence the particles get stuck in the HEPA filter. So ultra fine particles 0.01 to 0.1 are better filtered by true HEPA filters. 0.3 micron-sized particles are just at the sweet spot of being small and having a relatively straight path, so they pass along deep into the filter.
HEPA filters fail to filter gasses or fumes, so VOCs tend to pass right through these filters.
How do you remove resin fumes?
To Filter VOCs, odors and fumes, and other gaseous chemicals, Air purifiers use activated carbon. The highly porous activated carbon adsorbs the fumes by trapping them in the pores.
Activated carbon filters tend to be used up quickly if there are many VOCs in the air.
Is PECO technology most effective for 3d printing?
Photoelectrochemical oxidation air purifiers are claimed to be the best at dealing with 3D printer pollutants. It utilizes a filter lined with a catalyst activated by a photoelectric effect. The catalyst then produces highly reactive ions, destroying the ultrafine particles trapped inside the filter and destroying the VOCs passed through the filter.
This is an extension of an earlier technology called PCO, which utilizes photochemical oxidation. PECO technology claims that more reactive ions are produced that bond with the VOCs converting them to nontoxic compounds.
The company’s co-founders’ research backs this technology, and 2-3 companies use this method. However, this PECO technology is not as rigorously tested or standardized as HEPA technology. Also, the PECO technology air purifiers are quite expensive.
What air purifier type works best for resin printing?
The air purifier that works best for resin printing has a true HEPA filter purifying UFPs and an activated Carbon filter that eliminates fumes, odors, and VOCs.
Do air purifiers help with VOCs?
Air purifiers with carbon filters remove VOCs effectively.
Which Air Filters Work for 3D Printers?
An air purifier with a True HEPA filter and a carbon filter works best for 3D printers. Removing ultrafine particles and VOCs produced during 3D printing.
What is activated carbon?
Activated carbon is highly porous carbon produced at high temperatures.
Levoit Core 400s is the most energy-efficient and quiet air purifier. Its smart app features and controls will be a great addition to your workspace. Its True HEPA and activated carbon filters deal with 3D printer emissions efficiently.
