HEPA Air Purification Systems

A true HEPA filter captures at least 99.97% of airborne particles as small as 0.3 microns. This includes dust, bacteria, mold spores, and some viruses, making it a highly reliable option for improving lab air quality and reducing contamination.

HEPA filters alone do not remove gases or chemical fumes. To remove volatile organic compounds (VOCs), solvent vapors, or lab odors, you’ll need a purifier that includes an activated carbon filter in combination with the HEPA system.

HEPA filters remove 99.97% of particles 0.3 microns or larger, while ULPA filters are even more efficient—removing 99.9995% of particles down to 0.12 microns. ULPA systems are typically used in highly sensitive cleanroom environments.

Fan filter units are ceiling-mounted systems that pull in air, filter it through HEPA or ULPA filters, and push clean air downward in a laminar flow. They’re used in cleanrooms or controlled zones to maintain contamination-free environments.

Pre-filters should typically be changed every 6 to 12 months depending on dust load. HEPA filters can last 2 to 3 years, while carbon filters may require more frequent replacement—especially if used in areas with strong odors or chemical fumes.

Yes, HEPA purifiers are effective at capturing airborne virus particles, including aerosols similar in size to the COVID-19 virus. While they don’t kill viruses, they can significantly reduce their presence in shared indoor environments.

For compact spaces like tissue culture rooms or benchtops, a portable or tabletop HEPA purifier is ideal. These units offer targeted filtration with quiet operation and are perfect for small labs needing clean air in specific zones.
