IQAir's Super Efficient Pre-Max Prefilter retains 90% of coarse and fine dust, thus prolonging the life of the fan motor and subsequent HEPA and gas filters. Lasts 6-18 months, depending on usage and environment conditions.

High-Efficiency Pre-Filtration:
While most air purifiers use prefilters with particle efficiencies well below 20%, IQAir systems typically retain over 90% of particle mass in the pre-filter. As a result, IQAir's HEPA and gas phase filters are better protected from permature loading.

Large Filters:
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.
