The filter showed up fast, the sensor helped me to pin point the source of the pollutant by referencing the charts in the app

I did a lot of research on air purifiers after having mold grow on a home ERMI test and landed on this brand. I couldn’t be happier! They are stylish, quiet, and my allergy symptoms are so much better. I am super happy with all 4 units I bought and have great peace of mind that my air is clean especially during fire season.
