All of our inventory of Genuine IQAir PreMax and HyperHEPA filters now feature longer filter life and increased airflow. While the outer appearance has not changed, the filters are now made with lightweight inert thermoplastic separators. This has resulted in an increase of active surface area, more even filter loading and more than a 10% reduction in total weight. Enjoy more clean air and spend less on filter replacement costs than ever before!

PreMax Prefilter - F1 - Replace approximately every 18 months (based on average daily usage of 10h on speed 3)*
While most air purifiers use small prefilters with particle efficiencies well below 20%, the large, commercial-sized super-efficient IQAir PreMax prefilter typically retains over 90% of coarse and fine dust. The PreMax prefilter is thus the most efficient pre-filter of any household air purifier, allowing the Hyper-HEPA filter and V5-Cell to last up to 5 times longer than similar filters in ordinary air purifiers.

Hyper-HEPA Filter - F3 - Replace approximately every 4 years (based on average daily usage of 10h on speed 3)*
IQAir's HyperHEPA filter is tested and certified to filter dust particles down to 0.003 microns (the world's smallest particle) with a guaranteed minimum efficiency of over 99.5%. This is 100 times better than what can be achieved by ordinary HEPA technology. The Hyper-HEPA filter eliminates bacteria, viruses and combustion particles from automobiles and smoke through a nano-fiber structure. HyperHEPA filtration technology is the safest, healthiest and most effective way to clean the air. Air is filtered with no ozone, no ions, no UV, no chemicals or any other unhealthy byproducts. Unlike the HEPA filters used in conventional air cleaners, the IQAir HyperHEPA filter is manufactured to such a high quality standard that it conforms to the most stringent hospital and cleanroom requirements.
