Laser fume extractor airflow in CFM and m³/h
This table lists airflow, filtration and noise for 8 laser fume extractors from xTool, Glowforge and FumeClear. Airflow is shown as the manufacturer lists it and converted between CFM and cubic meters per hour (m³/h). 1 CFM is 1.699 m³/h. 7 of 8 extractors have a listed airflow.

|---|---|---|---|---|---|---|
| xTool SafetyPro AP2 | 150 m³/h | 88 CFM / 150 m³/h | up to 7 filter layers across the line. xTool lists 99.97% particle filtration. | Not listed as a number | designed for machines with a fume extraction of 150 m³/h or less; 3-inch exhaust pipe | xTool: SafetyPro AP2 air purifier page |
| xTool SafetyPro AP2 Max | 700 m³/h | 412 CFM / 700 m³/h | up to 7 layers, adds a formaldehyde filter | Not listed as a number | suitable if your machine's fume extraction requirement is 700 m³/h or less and its exhaust port diameter is within 60-110mm or 200-250mm | xTool: SafetyPro AP2 air purifier page |
| Glowforge Performance Laser Filter | 275 CFM | 275 CFM / 467 m³/h | activated carbon and HEPA (Glowforge Air Filter text) | Not listed | Glowforge Pro, Plus; 4" hose connector; 350W brushless DC motor | Glowforge: Performance Series tech specs (Pro, Plus) |

| FumeClear FC-2004 | 247 CFM | 247 CFM / 420 m³/h | multi-stage (model dependent) | <58dB | heavier smoke, higher-power lasers | FumeClear: 2000 Series comparison |
xTool P2S exhaust and the AP2 limit
xTool lists the P2S built-in exhaust fan at 145 CFM. Calculated: 145 CFM is about 246 m³/h. xTool lists the AP2 as designed for machines with a fume extraction of 150 m³/h or less. The P2S exhaust airflow is above that limit.
xTool's AP2 FAQ lists the P3 at 238 m³/h. It states that the AP2 “must be paired with a duct fan when used with P3.” No xTool statement on pairing the P2S with the AP2 is linked here.
The fume and room lookup runs the same comparison for any machine on the laser machines page. It also takes a CFM number from a manual.
