Best Air Purifier for 3D Printing – Hand-Picked and Tested!

I used the Creality Ender 3 V2 Neo for a while because I wanted to get a feel for how these devices work and explore 3D printing as a hobby.

However, due to a lack of time, I wasn’t able to use it as frequently as I had planned, so I eventually sold it.

Still, I noticed one major issue during use: a device like the Creality Ender 3 V2 Neo produces a significant amount of harmful particles, unpleasant odors, and fumes. If you plan to use a 3D printer indoors, rather than in a separate room, garage, or similar space, you definitely need a solution to deal with the airborne pollutants generated during printing.

While using this printer, I also had the opportunity to test how dozens of different air purifiers perform during operation. In this article, I’ll share a list of the best options you can buy.

Best Air Purifiers for 3D Printing

Depending on which filament you use, you will pollute the air more or less. PLA is the safest, while ABS and nylon are the most risky. If your printer has an enclosure, it keeps particles contained inside until they settle, making it slightly safer.

• ABS (Acrylonitrile Butadiene Styrene): Known for releasing styrene, which is potentially carcinogenic and has a strong, unpleasant odor. It often causes headaches.
• PLA (Polylactic Acid): Considered “safer” because it is corn-based, but it still releases lactide, which is less toxic yet still contributes to the number of airborne particles.
• Nylon and polycarbonates: Can release caprolactam and other irritants that affect the eyes and throat.

This means that HEPA and activated carbon air purifiers can drastically reduce the amount of ultrafine particles and VOCs produced by 3D printers.

IQAir HealthPro Plus – Best Option You Can Get

Without a doubt, the best air purifier you can get for 3D printing is the IQAir HealthPro Plus.

It’s a large, reliable, and highly efficient air purifier that easily captures harmful airborne particles, odors, and VOCs produced by 3D printers.

It uses a three-stage filtration system, including the PreMax F8, V5-Cell Gas & Odor Filter, and HyperHEPA Filter (H12/13). It doesn’t produce ozone and is 100% safe to use.

I often recommend the IQAir HealthPro Plus as one of the best air purifiers for smoke and VOCs, thanks to its high-density, pellet-based carbon filter.

With room coverage of up to 406 sq. ft. (37.7 m²), it’s suitable even if you’re running more than one 3D printer.

In our performance tests, the IQAir HealthPro Plus achieved some of the best results we’ve ever recorded, improving air quality by 96% in a 320 sq. ft. (30 m²) room.

Overall, the IQAir HealthPro Plus is the best air purifier for 3D printing you can buy.

Alen FLEX – Best for the Most People

Another excellent air purifier for 3D printing is the Alen FLEX. It uses a high-quality True HEPA filter but has slightly less carbon in its gas and odor filter.

The Alen FLEX doesn’t have smart features or an air quality sensor, but it delivered excellent results in our performance tests.

It’s also one of the quietest air purifiers we’ve tested and has one of the best CADR-to-noise ratios.

The Alen FLEX uses a three-stage filtration system: a pre-filter, a True HEPA filter, and an activated carbon filter. It doesn’t produce ozone.

With a motor rated at just 50W, it’s well optimized for power efficiency.

Overall, the Alen FLEX is the best air purifier for most people using 3D printers. It’s significantly more affordable than the IQAir while still delivering high efficiency.

Austin Air HealthMate Jr. – The Best Option for 3D Printing VOCs

The Austin Air HealthMate Jr. is very similar to the IQAir when it comes to high-quality carbon filtration.

However, it offers smaller room coverage, fewer features, and weaker airborne particle removal performance.

What stands out about the Austin Air HealthMate Jr. is its carbon filter, which contains 6.5 lb of carbon. This is the largest amount on the list and the heaviest carbon filter among all the air purifiers I’ve tested.

This confirms its outstanding ability to neutralize odors, VOCs, plastic fumes, and other pollutants associated with 3D printing.

Where the Austin Air falls short is in airborne particle removal. It operates much more slowly than some other air purifiers on the list, meaning it needs to run significantly longer than models like the Alen FLEX to achieve similar particle reduction.

Overall, the Austin Air HealthMate Jr. is the best choice if your primary concern is VOCs and strong odors produced by 3D printing.

Winix 5510 – Good for Small 3D Printers

The Winix 5510 is an air purifier I recommend very often and one of the best options for regular home use.

However, for more specific use, such as 3D printing rooms, there are some better choices, especially the models recommended earlier in this article.

What makes the Winix 5510 a solid option for 3D printing is its affordable price, True HEPA filter, pellet-based activated carbon filter, and excellent results in our performance tests.

But, it doesn’t contain enough carbon pellets to effectively capture VOCs and odors over the long term. For this reason, I recommend the Winix 5510 primarily for users with a single 3D printer who print only sometimes.

For more demanding or frequent printing, or for users running multiple 3D printers, the Winix 5510 may not be the best choice. In those cases, it’s worth spending a bit more and choosing the Austin Air or IQAir instead.

Final Thoughts

The particles produced by 3D printers can be truly harmful, and during printing, you can often notice an unpleasant burnt or plastic-like smell, sometimes mixed with other irritating fumes.

That’s why using an air purifier is an important line of defense and possibly the most effective way to reduce the harmful airborne particles generated by 3D printers.

In my opinion, the model you simply can’t go wrong with is the IQAir HealthPro Plus, while one of the best options for most people is the Alen FLEX.
