IQAir H-11 Pre-Filters last up to 18 months and capture smoke, mold spores and other allergens, and bacteria and viruses. IQAir H-11 Pre-Filters are HEPA filters, certified at ≥ 99% efficiency for particles as small as 0.3 microns.
New Edition™ filters feature an increase of active surface area, more even filter loading, longer filter life and a reduction in total weight, all resulting in greater airflow and higher particle holding capacity. With these improved filters, you get more clean air and save money on filter replacements.
H-11 Pre-Filters are the first stage of filtration for the GC series of IQAir purifiers.
