All of our inventory of Genuine IQAir PreMax prefilters now feature longer filter life and increased airflow. While the outer appearance has not changed, the filter is 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.

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 Gas and Odor filter to last up to 5 times longer than similar filters in ordinary air purifiers.
To minimize manufacturing costs, most air purifiers use very little filter material. IQAir uses commercial size filters that are able to collect more pollutants and last longer.
