Some manufacturers state that their shelters are "FEMA approved".  This is a misnomer - FEMA is strictly prohibited by law from "approving" a particular shelter.  Instead, FEMA recommends that all manufactured shelters be testing for compliance with FEMA standards.

The AeroSafe Tornado Shelter was tested by the National Wind Institute at Texas Tech University to the guidelines of FEMA 320 (2014) and ICC-500 (2014), and passed the testing.
