Depending on the level of air cleaning desired, the IQAir system can be operated as frequently as needed. For general air cleaning purposes, the system should filter the room air volume at least twice every hour on the set fan speed in order to achieve a significant air quality improvement. If the intensity of the pollution source is high or a high degree of purification is needed, more air changes may become necessary. More air changes may be achieved by selecting a higher fan speed and/or by running the room air cleaner more frequently. In order to achieve the desired number of air changes, more than one room air cleaner may be required, or an IQAir whole-house filtration system should be considered.
It is the customer's discretion as to how often they actually operate their IQAir system. All IQAir room air cleaners can be run 24 hours a day, if needed, without harm to the system.
Generally, when running the system at speed 6 it will take about 15 minutes to clear 50% of the particles in a 900 square-foot room. A smaller room at the same fan speed would achieve results more quickly. Keep in mind that fan speed and room measurements can affect the length of time to achieve results.
For more information, please refer to the HealthPro™ User Manual, chapter 4.3, Fan Speed & Air Delivery.
