H2 Modular HEPA & Activated Carbon Filter System

Designed around a larger, more readily available 125x125x30mm dual stage carbon and HEPA air filter, this system breathes better than other "Vento" style filtration system and readily allows for fume extraction and adaptation.

FEATURES

✓ Multi-Stage Filtration
Captures fine airborne particles with a HEPA filtration stage while the activated carbon stage helps reduce odors and volatile organic compounds (VOCs) generated during printing.

✓ Larger Filter Surface Area
Our oversized filter design provides lower airflow restriction than many compact filter solutions, helping maintain strong exhaust performance and more consistent chamber conditions. Unlike other Vento styled exhaust filters, this oversized design helps maintain lower chamber temperatures when printing materials like PLA and PETG, without having to remove the filter.

✓ Modular 4" Exhaust System
Exclusive modular attachment system supports standard 4" (100mm) ducting, allowing filtered air to be directed outside your workspace when desired. The duct can be routed to either side, up, or down for whatever you need!

✓ Serviceable Design
Filters can be replaced without reprinting the entire assembly, helping reduce long-term operating costs.

✓ Designed for Engineering Filaments
Ideal for ABS, ASA, Nylon, PC, PETG, and other materials that generate noticeable odors, fumes, or ultrafine particles during printing.

✓ Engineered for Long-Term Leak Free Designs
This system uses TPU gaskets in every place air can escape from the filtration path. TPU seals better and holds up much longer than other foam tape sealing applications.
