Replacing the filter set every 6-12 months is recommended to ensure optimal performance. When the red lights flash, it is time to check and replace the filters.

It can be challenging to distinguish between the two terms, but California has taken the initiative by implementing strict regulations for air cleaners sold in the state. These regulations mandate that air cleaners must be CARB Certified by the California Air Resources Board and meet other specifications, ensuring they are environmentally and Ozone safe. The YesAir is incredibly safe regarding Ozone levels, testing 98% lower than the certified limit, essentially testing Zero Ozone.

The YesAir 1000 is a certified Ozone-Safe air purifier. The Ionizer used in the YesAir tested 98% lower than the certified limit (0.050) at 0.001 parts per million and is safe around humans and pets. It's lab tested under UL STD. 867 and California Air Resources Board (CARB) Certified. The built-in Ionizer is optional and turns off if desired. Learn more about YesAir Filter Technology.

An Ozone Generator is a machine with a specific purpose (NOT an air purifier) that emits high amounts of Ozone to combat issues like mold accumulation after a flood. It is unsafe for humans or pets to be present when these machines are running as they produce high levels of unsafe Ozone (O3), which can cause difficulties in breathing.

The YesAir 1000 MED+ODOR filter system provides the ultimate protection against virus-size particles, odors, and gases. Lab test results show the MED+ODOR Medical (H13) HEPA filter removes 99% of the H1N1 virus in lab-conducted tests. As we conduct more testing with the lab, we will update the COVID-19 information.

Once done, turn on the unit and hold the "Sleep" button on the control panel for 3 seconds to clear the memory and reset the filter replacement reminder.

The YesAir has an Auto Mode that activates when there is light in the room and automatically switches to Sleep mode when the room gets dark. However, you can switch to manual speed mode to prevent the YesAir from going to Sleep mode automatically due to changes in ambient light.
