What to look for

  1. A mask only protects you if it fits. Practice putting it on before an emergency.
  2. Check filter expiration dates and store spare filters sealed.
  3. Plastic sheeting and duct tape let you seal a room to shelter in place.
  4. Follow instructions from public health officials during any chemical or radiation event.

Common questions

What is the difference between a gas mask and an N95?

An N95 filters particles like smoke and dust. A gas mask with the right filter also protects against many gases and vapors. Neither protects in every situation, so follow official guidance.

Do I need a Geiger counter?

A Geiger counter or dosimeter tells you if radiation levels are elevated. Most families never need one, but they are valuable for anyone living near nuclear plants or preparing for the worst.

What is a Faraday bag?

A Faraday bag blocks radio signals. People use them to protect electronics from electromagnetic pulses and to stop phones and key fobs from being tracked or hacked.
