Corrections

A story about Boulder Valley School District that appeared on Page 1A of Friday’s Camera should have reported Michael Behar was still hoping to work with Bear Creek Elementary’s parent-teacher organization to raise money to buy individual HEPA air filters for each classroom. It also should have reported the filters the district bought for its schoolwide HVAC systems are an improvement, but aren’t as effective as higher level filters because officials with the district told him in an email that the higher-level filters could comprise the school systems.
