  • The card can be worn or placed in the area where people are.
  • Simply compare to the color of the ozone test cards to read the level of ozone.

Comtech Research ran a test on an Air Oasis 3000 with the test card 2" away. After one hour (the normal test time), the ozone test card showed NO color. And it took hours before the card showed any color, proving that the ozone levels from the Air Oasis was quite safe.

HINT: You cannot test ozone quantity in the front of an ozone generator (such as the GreenAir Machine or the NA50 in real time. The proper way is to test the room's ozone density away from the ozone generator in your living space, (where people and pets are).
