An air purifier is one of those small but useful accessories that can make resin 3D printing far more comfortable—especially if you’re sensitive to the unmistakable resin smell. In this updated Elegoo Mini Air Purifier review, we take a closer look at how well this compact unit handles odor reduction and whether it truly adds value to your resin printing workflow.
If you’ve ever wondered whether there’s a simple, affordable way to reduce resin fumes without installing a full extraction setup, this little device might be worth a look. I discovered the Elegoo Mini Air Purifier while browsing the Elegoo store and ordered it immediately to test with my resin printers. As the name suggests, it’s a small, cartridge-style purifier designed to help minimize unwanted smells during printing.

Elegoo Mini Air Purifier Review: Does It Really Work for Resin 3D Printing?
In this review, we break down how the purifier works, what you get inside the box, how well it performs, and whether it’s worth adding to your resin setup. If you’ve been asking yourself whether resin 3D printing odors can be controlled without spending a fortune, this review will give you the clarity you need.
Quick Verdict:
What’s in the Box?
When I got the Elegoo Mini Air Purifier, I unpacked it and was presented with two filter systems!
In the box, you will get:
- 2 filter systems, each with a carbon filter
- Power supply adapter, 5V, 1000mA
- Micro USB charging cable
- Instructions in two lines glued to the top of the lid as a sticker
Note: The supplied instructions are minimal — just a sticker that says to remove the protective paper. No lifespan guidance or maintenance schedule is included.
Technical Specifications
| Voltage | 5V, 1000mA |
| Dimensions | 43mm x 43mm x 109mm (LxWxH) |
| Fan Speed | 4000 RPM |
| Battery Capacity | 2000mAh |
| Power | 0.3 Watt |
| Running Time | 24 hours (single charge, per manufacturer) |
Installation & Setup
I pulled off the lid labeled ELEGOO and saw the wrapped carbon filter that was visible in the upper white lid.
Unpack the charcoal filter carefully — loose charcoal dust is messy. Put the unpacked carbon filter back into the cap and place it on the base. The purifier houses a small fan, battery, and electronics under the blue grille.
There is a fan, battery, and some electronics under the blue protective grille.
How It Operates
Charge both units with the included cable and adapter. Once charged, press the front button to start. Important: there’s no operation LED—only a charging indicator—so the unit runs very quietly and you may need to listen to confirm operation.
Placement: put the purifier inside your printer enclosure or near the build plate during printing. The unit draws air from the top, filters it through activated carbon, and exhausts at the base. This is a recirculating, localized odor-reduction system.
Real-World Performance
In daily use the units reduced the sharp, chemical smell from standard resins by approximately 60–70%. That makes printing in small rooms or apartments noticeably more comfortable. However, they do not remove all VOCs — think of them as an odor reducer rather than a health-grade air cleaner.
Noise and Power
The purifier is very quiet (practically inaudible in most printing spaces) and runs for up to ~24 hours on a single charge according to the specs. In practice, runtime depends on fan speed, battery age, and whether the device is run continuously.
Pros & Cons
Pros
- Rechargeable & portable
- Very quiet operation
- Reduces odor noticeably (60–70%)
- Small footprint — fits inside many printer enclosures
- Includes 2 filter cartridges
Cons
- No operation LED (only charging light)
- No official filter lifespan guidance
- Replacement filters not sold separately (as of 2025)
- Not a substitute for ventilation or a proper VOC scrubber
Does It Remove Harmful VOCs?
No — the Elegoo Mini uses activated carbon to absorb and mask smells. Activated carbon can reduce some organic compounds and odors, but it is not a certified VOC eliminator. For safety, always combine local odor control with room ventilation or a dedicated air exchange system when printing regularly.
Who Should Buy This?
- Beginners & hobbyists printing small models in cramped spaces.
- Apartment users who need a low-cost way to reduce odor during prints.
- Users of strong-smelling standard resins who want comfort while printing.
Comparison: Elegoo Mini vs Other Options
| Option | Best for | Notes |
|---|---|---|
| Elegoo Mini | Small enclosures, portability | Good odor reduction; limited long-term filters |
| Full-size HEPA+Carbon Purifier | Whole-room VOC/particle reduction | Better at particles; pricier and larger |
| DIY Vent + Charcoal | Budget-conscious users | Effective if vented outside; requires setup |
| Low-odor Resins | Users avoiding smell at the source | No additional hardware; may cost more |
Are Replacement Filters Available?
As of this update (2025), Elegoo does not list replacement carbon filters sold separately. That means long-term users either need to source third-party filters or replace the unit when the included filters saturate (community estimate: ~1–3 months of regular use).
Final Verdict
The Elegoo Mini Air Purifier is a useful, budget-friendly accessory to reduce resin odors in small spaces. If you need a quiet, portable odor reducer for a small enclosure, this is worth the money — but treat it as an odor-control convenience, not a safety device.

Buyer’s Tip
If you print often, pair the purifier with proper ventilation or low-odor resin for the best experience. Running two units inside larger enclosures helps coverage.
FAQ
Can the Elegoo Mini Air Purifier remove all resin fumes?
No. It reduces odor but does not eliminate all VOCs. Always ensure proper room ventilation.
How long do the filters last?
Elegoo doesn’t provide official lifespan data. Community reports suggest ~1–3 months with regular use.
Can I use just one unit instead of two?
Yes, but two units give better coverage, especially in larger enclosures.
Is it compatible with non-Elegoo printers?
Absolutely — it’s a standalone device that works with any resin 3D printer.
