Ensure your PF40 Kit operates at peak capacity by replacing the filter pads in a timely manner. This will allow your IQAir system to trap the most coarse-dust particles possible. Please note that this is a replacement filter package, not the PF40 Kit.
Replacement interval: Varies – check and wash every 2-4 weeks, then replace when washing is no longer effective.
This replacement filter purchase includes five pads.
