Yeah ideally something merv10 plus. Off the shelf filters aren't usually rated that way, so something like a 1500 or better gets you in that range.

No mention that all @tdsb.on.ca schools except for new installations have MERV10 filters in their HVAC, not the MERV13 filters recommended by ASHRAE and other expert orgs. Every other school board in the GTA has switched to MERV13, and dealt with any issues afterwards (it's rare). There's no excuse.

Lasko 20” fans with a MERV10 (they sell them like that, model FF305) will clear out wildfire particulates in your room a lot faster than not having one. And then once you are ready to change out the filter, you can upgrade to Filtrete 20”x20” MERV13 or so.

After a control bd change it started throwing air flow faults. Despite the only change being the control bd, manager refused warranty work until I had the condenser cleaned. Seems the 3 yr old cond behind a merv10 filter was blocking airflow. Took photos of the shiny condenser.
