The Thunder Bay Catholic District School Board (TBCDSB) now has 20 more HEPA air filters for area schools.

In an email to Acadia News Tuesday, spokesperson Alex Frankow said officials received the stand-alone units in a recent shipment.

Frankow also laid out what the board is doing in terms of ventilation in the classrooms:

Fully automated air quality control systems through Honeywell Solutions for all facilities
Demand Control Ventilation used to maintain air quality and automatically adjust spaces in response to changes in conditions, occupant numbers and CO2 levels
Full control of heating, ventilation and air systems via remote access
Portables are fully equipped with automated air exchangers

The Ministry of Education promised Monday an additional 40,000 filters for school boards and 9,000 to child-care settings.
