IQAir GC Series Post-Filter Sleeves are the final stage of filtration in IQAir GC Series Air Purifiers. These sleeves slide snugly over each of the 4 GC Series filter cartridges. They are constructed with electrostatically charged material to trap nearly 99% of allergen particles and harmful microorganisms measuring down to 0.003 microns. Air moves through the post-filter sleeves for a final pass of filtration before clean air is released into your space. These sleeves are filter F3 on your control panel and they fit all IQAir GC Series air purifiers.
