IQAir GCX Series Post-Filter Sleeves are the last stage of filtration in IQAir GCX Series air purifiers. These post-filter sleeves slide snugly over each of the 4 GCX 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 GCX Series air purifiers.
