+# Basement Workshop Air Filtration
+
+Both the north and south basement workshops have Axminster air particle filters.
+These are suitable for removing the worst of suspended dust from the air.
+
+They are not helpful for particularly fine or hazardous dust/particles/fibres (i.e. anything you would usually use a HEPA filter or class H vacuum for).
+
+## Essential Information
+
+- Responsible Person(s): Dan Nixon
+
+## North Workshop Filter
+
+Currently the filter in the north basement workshop is serviceable.
+
+It is effectively stock and located in the position it will remain in.
+
+Please use it when creating dust in the north workshop (e.g. when running the Workbee CNC router).
+
+## South Workshop Filter
+
+The filter in the south workshop is not currently serviceable and not mounted in a suitable position.
+
+## To Do
+
+- [ ] New control system, with:
+    - network remote control
+    - automatic start/stop based on presence and/or air quality
+- [ ] Install new control system, in
+    - [ ] south workshop filter
+    - [ ] north workshop filter
+- [ ] Mount south workshop filter overhead in a suitable central location

+# Main Workshop Air Exchange
+
+There is an air extraction fan for the main space fitted above the front door.
+The control for it is located in the south west corder of the ground floor main workshop.
+
+When operated, the negative pressure in the room draws in fresh air from whatever source is available.
+Such sources include:
+
+- The ceiling vent above the inner door, via the ceiling void, eventually feeding from the vents in the boiler room
+- Any open windows (e.g. in the goldfish bowl)
+- Via other routes through the building when the inner door is held open (e.g. via Vane or the rear/courtyard door)
+
+This fan can be used to maintain the main workshop at a comfortable balance of temperature and air quality.
