Learn about the respiratory dangers caused by tornadoes:

www.stlpr.org/health-scien...

Tornadoes can cause breathing problems even after they’re gone

Debris kicked up during the storm and building materials from destroyed or damaged buildings can cause respiratory issues such as asthma flare-ups and infections.

Tornadoes devastated many areas of St. Louis & we are mobilizing to provide DIY air filters to combat “Tornado Lung,” a serious respiratory threat. We are committing $2.5k and raising another $2.5k.
