Modix Active Air Filter

Modix Active Air Filter (MAAF) is an external air filter device. The filter cleanses the printer's chamber by capturing micro-particles and gas fumes that are released from melted filament throughout the 3D printing process.

MAAF provides a constant air cleansing process during the entire printing process, circulating the air in and out and back into the printer while cleaning it repeatedly.

Multi-layer filtering
A large fan inside the device draws the air from the printer through a flexible vent tube connected to the top of the device. The air is then guided through a set of three filters before it is circulated back into the printer.

The triple filter system includes

  1. Pre-Filter – Remove large dust particles from the air.
  2. HEPA Filter – High-Efficiency Particulate Absorbing (HEPA) filter, composed of a mat of randomly arranged fiberglass fibers designed to capture tiny particles released during printing.
  3. Active Carbon Filter – Clean the air from toxic fumes released during the 3D printing process.

It is about your health!
Sub-micron particles and fumes released during the plastic melting process pose risk to your health. Therefore, every owner of a Modix 3D printer is strongly advised to install an air filter. Air filter is a MUST-HAVE add-on if you intend to print with any plastic beyond PLA, i.e. PETG, ABS… Although common knowledge is that printing PLA in a well-ventilated room is fine, there is no clear definition of proper room ventilation and during the winter and summer times windows are normally closed.

Note: Filters will require routine replacement. Replacement filter sets available here:
