1. Do you advise running the IQAir when the replacement filter light is on?
Yes, it is safe to continue using the system while the filter life indicator is on. What color is the light?
The filter life indicator LEDs signal four possible stages in the life of the filter:
Green: The filter is within 80% of its estimated lifespan.
Orange: The filter is approaching the last 20% of its lifespan.
Red: The filter has reached the end of its estimated lifespan.
Red (blinking): The filter has exceeded its estimated lifespan and should be replaced immediately. The system’s effectiveness may be significantly reduced due to decreased airflow (clogged particle filters) or reduced efficiency (saturated gas filter).

2. Does it still clean the air, or is it releasing polluted air if the filter needs replacement?
The system continues to filter air—it does not release pollutants. Air still passes through the filtration stages that have not been saturated, although overall performance may be reduced.

3. What do you suggest given immune concerns and the need for clean air?
Given your situation, we recommend:
Continuing to run your system while waiting for the replacement filter
Operating it at a moderate to higher fan speed (if comfortable) to maximize air circulation
Replacing the filter as soon as the new one arrives for optimal performance

Your HealthPro Series is designed to provide continuous protection. Even with the filter change indicator active, it is still far better to run the system than to leave the air untreated—especially for someone who has health concerns.
