Does it claim to KILL Covid?

No, not that I'm aware of.

Looked up Xlear and found this:

"The Federal Trade Commission sued Xlear, Inc., a Utah-based company, for violating the COVID-19 Consumer Protection Act,
alleging that it falsely pitched its saline nasal sprays as an effective way to prevent and treat COVID-19".
