X1C / P1S Activated Carbon / HEPA Air Filter

Reusable Air Filter for X1C and P1S 3D Printers

This 3D-printable replacement air filter is designed to make maintenance simple and efficient while delivering high-quality air filtration. It’s compatible with affordable, readily available automotive HEPA charcoal filters, giving you the flexibility to replace filter materials as needed.

 

 

Materials: 

• High-temperature filament such as ABS, ASA, or PC 

 

 

• Automotive HEPA Cabin Filter Material 

 

• Activated Carbon Media 

 

 

Here’s how it works:

1. Cut a layer of HEPA filter material to fit inside the 3D-printed housing.
2. Add approximately 70 grams of activated carbon on top to enhance filtration performance.
3. Secure everything with the 3D-printed lid, which slides snugly into place.

(NOTE: The HEPA material is not required as long as your infill percentage is high enough - This will allow for more airflow) 

 

 

Additional Features: 

• ~15% More Airflow Surface Area 

• Highly Cost Effective 

• Customizable Top & Bottom Patterns using Infill 

• Directional Arrows

• Easy Grab “Pig Nose” Grips 

• No Additional Hardware Needed

 

 

This reusable design ensures consistent performance and promotes sustainability by minimizing waste; with the added benefit of reducing printer costs. With durable 3D-printed parts and replaceable filter materials, it’s a practical and cost-effective solution for maintaining clean air during printing.

 

Whether you’re running long print jobs or prioritizing air quality in your workspace, this system provides reliable and easy-to-use filtration to meet your needs.

 

Since chamber temperatures can exceed 50 degrees Celsius, I recommend printing this in ABS, ASA, PC, or an equivalent fiber-reinforced filament (I used Bambu ABS-GF). 

 

 

Printing: 

Make sure your build plate is clean as the first layer has lots of small intersecting lines
