Understand the air you breathe.

TELLUS, born in Utah, is on a mission to keep you informed and safeguard the well-being of every family member – whether at home, work, or anywhere in between.

The worst air quality you experience might be in your living room.

Indoor air quality can suffer from factors like trapped and stagnant air, as well as pollutants from sources like candles and dust, impacting where you spend 80% of your time.

Know when it's safe for you and your family.

The air around your neighborhood may look clear, but that doesn't mean it's pollution free.

In some cases, indoor air pollution was 100X greater.

EPA studies found indoor air pollutants were generally 2 - 5 times greater than outdoor pollution levels.
