# What micron size are the particles people talk about?

## Answer

In this field you will hear **1–5 microns** a lot. A micron is one-millionth of a meter. The claim is that particles in that range can travel past the nose and throat into smaller airways, which a coarse grain of table salt cannot do.

That range is industry-typical language, not a lab result this magazine ran on every cave in America. Generators differ. How long they run differs. Whether the machine is on while you sit or only beforehand differs. Some hosts will show you a flashlight beam so you can see that *something* is in the air. That is a demonstration, not a prescription.

Do not let a number become a medical dose. If a website promises a precise milligram delivery into your lungs, be cautious. Ask the host. Ask your physician if you have reactive airways.
