Germs hide in plain sight. Echo Clean helps you stop them safely, and on the go.

What is CFU/in²?

CFU stands for Colony Forming Units, and it measures the number of viable bacteria or fungal cells on a surface that are capable of growing into colonies.

When you see CFU/in², it means the number of living microorganisms per square inch. It's a common metric in microbiology used to quantify how "germy" a surface is.

From hotel surfaces to airplane seats, you're constantly touching hotspots you’d rather not think about. Germs travel too, be ready.
