Thank you for sharing your feedback. I understand it can be difficult to give a fair rating when the unit doesn’t seem to show any change in your environment.
The air quality indicator may register 0 if the sensor does not detect particles above its threshold. This can happen in certain environments, and having plants in the house is not likely to affect the sensor readings. To ensure accurate performance, we recommend gently cleaning the sensor area with a soft brush or cotton swab, and making sure the unit is placed in an open space at least 2 feet away from walls or objects.
Our support team will be reaching out to you directly to assist further and guide you through troubleshooting steps.
