Extensive research has reported that HEPA filters can significantly reduce airborne levels of Aspergillus and other fungi and hospital-related Aspergillus infections. A meta-analysis of 6 published studies involving 759 patients with neutropenia reported that use of HEPA filters in hospital rooms was associated with a 71% lower rate of invasive fungal infections (relative risk, 0.29; 95% CI, 0 An ultrafiltration filter has a pore size around 0.01 micron. A microfiltration filter has a pore size around 0.1 micron, so when water undergoes microfiltration, many microorganisms are removed, but viruses remain in the water. Ultrafiltration would remove these larger particles,  Pros & Cons of HEPA Filter vs. Ionic Purifier Systems HEPA Filter Pros: Excellent at capturing large and fine particles and preventing them from re-entering the air.
